A climatic baby step forward beats a leap backward

The world surely is approaching a danger point when the abrogation of an inadequate agreement is cursed as a disaster. The Paris Climate Summit goals can’t be characterized as anything significantly better than feel-good window dressing, but the argument that the world has to start somewhere is difficult to challenge. Better to take a baby step forward than a leap backward.

As always, we must ask: Who profits? The Trump administration’s decision to withdraw from the Paris Accord is due to factors beyond Donald Trump’s astounding ignorance and his contempt for science or reality. There is a long history of energy company denial of global warming, a well-funded campaign.

Never mind that a widely cited 2015 study by the Stockholm Resilience Center, prepared by 18 scientists, found that the Earth is crossing several “planetary boundaries” that together will render the planet much less hospitable. Or that two scientific studies issued in 2015 suggest that so much carbon dioxide already has been thrown into the air that humanity may have already committed itself to a six-meter rise in sea level. Or that the oceans can’t continue to act as shock absorbers — heat accumulated in them is not permanently stored, but can be released back into the atmosphere, potentially providing significant feedback that would accelerate global warming.

So strongly has public opinion swung on global warming that even Exxon Mobil and Royal Dutch Shell joined a vast array of multi-national corporations decrying the Trump withdrawal, leaving the United States as one of only three countries outside the Paris Accord. Exxon Mobil claims to support the agreement and is “well positioned to compete” under its terms. A measure of skepticism over this recent conversion is forgivable. Exxon has spent more than $33 million on denying global warming from 1997 to 2015, according to DeSmog, a total believed to be an underestimate. DeSmog summarized these findings this way:

“Despite its advanced knowledge of the climate disruption fueled in large part by oil, gas and coal pollution, ExxonMobil turned its back on crafting responsible solutions and instead funded a sophisticated campaign to sow doubt and delay action to curb carbon emissions — honing the tobacco industry’s playbook with even more advanced public relations, advertising and lobbying muscle.”

A separate DeSmog report says that Exxon corporate documents from the late 1970s unequivocally declare “there is no doubt” that carbon dioxide from the burning of fossil fuels was a growing problem well understood within the company. Inside Climate News reports that Exxon confirmed the science on global warming by the early 1980s while publicly mocking those models for decades beyond.

Tobacco is good for you and so is a warming planet

Such denialism is alive and well. A leading global warming denialist lobbying outfit, the Heartland Institute, had this to say about the withdrawal from the Paris Accord: “Angela Merkel and what is left of the E.U. are not happy (itself a victory), but fake science and globalism would take a big hit with this move.” So childish it could have been written by Donald Trump himself! Lavishly funded by Exxon, the Heartland Institute originally was a propaganda outfit for the tobacco industry, going so far as to deny the health effects of second-hand smoke.

Then there is NERA Consulting, which the Trump administration cited in its announcement of the Paris withdrawal. The White House statement claimed that “meeting the Obama Administration’s requirements in the Paris Accord would cost the U.S. economy nearly $3 trillion over the next several decades” and has already cost six million industrial jobs. Among other problems with this phantasmagoria is that none of the commitments of the Paris Accord have actually been implemented. Thus it is difficult to determine how the accord caused those jobs to disappear.

What is NERA Consulting? It describes itself as “firm of experts” that provides economic analysis to corporate clients. DeSmog reports that NERA has repeatedly, sometimes anonymously, issued reports on behalf of coal, liquified natural gas and other energy corporations that claim wildly inflated job and/or economic costs. Media Matters for America reports that a NERA report attacking the U.S. Environmental Protection Agency’s carbon pollution standards “has been thoroughly debunked by multiple experts” on multiple grounds, including failure to acknowledge any economic benefits. The NERA report was explicitly prepared for several energy-industry lobbying groups.

Earlier, NERA was involved in lobbying for the tobacco industry; a vice president said the tobacco industry should aim to explain the health “benefits” of smoking.

The Koch brothers, Charles and David, are also active funders of global warming denialism, and the two stand to profit enormously from the Alberta tar sands. The Koch brothers own close to two million acres that, should that land be fully exploited, would throw another 19 billion metric tons of carbon emissions into the atmosphere. The International Forum on Globalization estimates that the Kochs stand to make more than one million times more than the average Keystone XL pipeline worker over the life of the pipeline, based on potential profits of $100 billion.

Polar warming outpaces warming elsewhere

It is not a long distance from the Alberta tar sands to the Arctic, where global warming is particularly pronounced. Consistent with predictions that the polar regions would experience the sharpest rise in temperatures, the Arctic is 3.5 degrees Celsius warmer than it was at the beginning of the 20th century with the region’s sea surface temperatures up to 5 degrees higher than the 1982 to 2010 average. Much worse could be on the way, the U.S. National Oceanic and Atmospheric Administration warns in its 2016 Arctic Report Card:

“Warming air temperatures in the Arctic are causing normally frozen ground (permafrost) to thaw. The permafrost is carbon rich and, when it thaws, is a source of the greenhouse gases carbon dioxide and methane. Northern permafrost zone soils contain 1330-1580 billion tons [of] organic carbon, about twice as much as currently contained in the atmosphere. Tundra ecosystems are taking up increasingly more carbon during the growing season over the past several decades, but this has been offset by increasing carbon loss during the winter. Overall, tundra appears to be releasing net carbon to the atmosphere.”

Long before the release of such quantities of carbon throw the climate out of control, permafrost melting has begun to alter the Canadian Arctic’s environment in worrisome ways. In an article for Inside Climate News, Bob Berwyn writes:

“Huge slabs of Arctic permafrost in northwest Canada are slumping and disintegrating, sending large amounts of carbon-rich mud and silt into streams and rivers. A new study that analyzed nearly a half-million square miles in northwest Canada found that this permafrost decay is affecting 52,000 square miles of that vast stretch of earth—an expanse the size of Alabama. According to researchers with the Northwest Territories Geological Survey, the permafrost collapse is intensifying and causing landslides into rivers and lakes that can choke off life downstream, all the way to where the rivers discharge into the Arctic Ocean.”

At the other end of the Earth, Antarctic temperatures are up to 3 degrees C. higher since the 1950s and they could increase an additional 5 degrees by the end of the century.

So what happens if the increase in greenhouse gases continues indefinitely? Possibly, global warming unprecedented for more than 400 million years. A study by researchers at Britain’s University of Southampton and University of Bristol, and Wesleyan University in the U.S., reports that if all readily available fossil fuel is burned, by the mid-23rd century atmospheric carbon dioxide concentrations would be around 2,000 parts per million — levels not seen since 200 million years ago. Lead author Gavin Foster said:

“However, because the Sun was dimmer back then, the net climate forcing 200 million years ago was lower than we would experience in such a high CO2 future. So not only will the resultant climate change be faster than anything Earth has seen for millions of years, the climate that will exist is likely to have no natural counterpart, as far as we can tell, in at least the last 420 million years.”

If all the Earth’s ices melted (which they would at such levels of warming and carbon dioxide release), sea level would rise more than 60 meters (more than 200 feet).

Paris commitments well short of Paris goals

At the conclusion of the Paris Climate Summit, the world’s governments say they agreed to hold the global temperature increase to 1.5 degrees Celsius, but in actuality committed to nearly double that. Nor is there any enforcement mechanism; all goals are voluntary. The summit, officially known as the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, or COP 21, anticipates peer pressure will encourage signatories “to reach global peaking of greenhouse gas emissions as soon as possible” and then “undertake rapid reductions thereafter.”

The Paris goals are based on the Intergovernmental Panel on Climate Change (IPCC) report issued in 2014, which foresees a rise in greenhouse-gas emissions for years to come, to above 450 parts per million, before falling to 450 ppm by 2100, which the report says is necessary to hold the global temperature rise to 2 degrees. Unfortunately, the IPCC report relies on several technological breakthroughs, including capture and sequestration of carbon dioxide, which are not yet close to being feasible.

The now discarded U.S. goal had been to reduce greenhouse-gas emissions by 26 to 28 percent in 2025, relative to 2005 levels. The European Union, Brazil, Canada, Japan, India and Australia have committed to cutting their greenhouse-gas emissions by anywhere from 26 percent (Japan) to 40 percent (EU) by 2030. China didn’t commit to a specific cut but said it would reach a peak in its greenhouse-gas emissions by 2030. The EU goals have an additional barrier, however — the British government under Theresa May has been working hard to significantly weaken draft EU climate and energy rules, including efficiency standards, even though the rules wouldn’t take effect until after Brexit.

A critical weakness of the assumptions underlying these goals is that the IPCC panel is asserting is that the cost of bringing global warming under control will be negligible, less than 0.1 percent annually during the course of the 21st century. No more than a blip noticed only by statisticians. There need be no fundamental change to the world’s economic structures — we can remain on the path of endless growth.

The Earth, alas, does not possess infinite resources. Certainly there should be a continued push toward the use of renewable energy sources in place of fossil fuels. But the idea that “green capitalism” will magically solve the problems of capitalism is a chimera. There is no way around the need to consume less and align production to human need rather than private profit. Capitalism won’t offer people displaced from dirty industries new jobs, and if the only option someone has to feed their family is take a job in the oil sands or in a coal mine, it is pointless to blame those workers. Then there is the “grow or die” dynamic imposed on capitalists through relentless competitive pressures. As Fred Magdoff and John Bellamy Foster, in their book What Every Environmentalist Needs to Know About Capitalism, write:

“ ‘Green capitalism,’ even if products are produced using the utmost environmental care and designed for easy reuse, offers no way out of a system that must expand exponentially and thus continue to ratchet up its use of natural resources, its chemical pollution, its contaminated sewage sludge, its garbage, and its many other toxic substances. Some of these ‘fixes’ will probably slow down the rate of environmental destruction, but the magnitude of the needed changes dwarfs these approaches.” [page 120]

There are no free lunches. Doing what is necessary to keep the climate from going out of control, with catastrophic consequences, will require more economic disruption than the IPCC acknowledges. But the price of continuing business as usual will be much higher. Our descendants are not likely to see short-term corporate profits a fair exchange for a less livable world.

Global warming will accelerate as oceans reach limits of remediation

If humanity stopped all production of greenhouse gases today, Earth would experience several decades more of additional global warming. That is not simply because the carbon dioxide, methane and other greenhouse gases thrown into the atmosphere by human activity won’t disappear in a day, but because the oceans can’t continue to act as shock absorbers.

Earth has tipped into a heat imbalance since 1970, and this excess heating has thus far been greatly ameliorated because the world’s oceans have absorbed 93 percent of the enhanced heating since the 1970s. This accumulated heat is not permanently stored, but can be released back into the atmosphere, potentially providing significant feedback that would accelerate global warming.

The latest in a series of scientific reports detailing the disastrous course of global warming, “Explaining Ocean Warming: Causes, Effects and Consequences,” concludes that the mean global ocean temperature will increase by as much as 4 degrees Celsius by 2100. In addition to the increasingly unstable weather, more potent tropical cyclones, displacements of aquatic life and boost to atmospheric temperatures that such a rise would cause, massive amounts of frozen methane hydrate in the depth of the seas could be thawed, adding a potent new source of greenhouse gases.

Dozens of climate scientists from around the world contributed peer-reviewed work to the report, research that in turn is based on more than 500 peer-reviews papers. The report builds on the work of the Intergovernmental Panel on Climate Change (IPCC), which in turn was the basis for the Paris climate summit in late 2015. That summit was noteworthy in setting a goal of limiting the increase in temperature to 1.5 degrees above pre-industrial levels, instead of the previous target of a 2-degree rise, often cited as the outer limit before uncontrollable changes are inevitable.

But even if all the national pledges of the Paris climate summit were achieved, global temperatures would rise 2.2 to 3.4 degrees C. by 2100, and the likelihood of all those pledges actually being met are minuscule as there are no enforcement mechanisms. A list of major countries’ pledges reveal a failure to make adequate progress, with many pledges dependent on “cap and trade” scenarios that often amount to subsidies for polluters.

Paris climate summit pledges inadequate

The “Explaining Ocean Warming” report does not sugar-coat that, stating in the conclusion that a fulfillment of the Paris pledges would not result in a return to hospitable conditions. The report says:

“[T]hey actually represent a ‘minimum ambition’ to prevent dangerous anthropogenic interference with the climate system. Achieving the ‘minimum ambition’ will already bring major changes in the functioning and resources of the ocean as we know them. Exacerbating an already concerning situation is the fact that the absorptive role of the ocean is also predicted to decline in the 21st Century, suggesting that the physics and chemistry of the ocean will be significantly different by 2100. As atmospheric CO2 continues to increase as a result of our activities, the solutions (i.e. mitigate, protect, repair, adapt) become fewer and less effective, thus decreasing the long-term ability of humankind to cope with the changes in the ocean that are now being observed.”

The report explains that, volume to volume, sea water is 4,000 more times efficient at retaining heat than is air, providing thus far a buffer to further global warming. But how long can the oceans do this? And at what cost? Coral reefs are dying, sea life patterns are changing, fisheries are in danger of collapsing and oceans are becoming more acidic. Further changes are locked in for decades ahead already, and humanity is ill prepared for this as the stresses on the seas through this excess warming are barely understood. The report says:

“[T]he consequences of increasing human activities have indeed injected vast quantities of heat into the ocean, shielding humanity on land, in so doing, from the worst effects of climate change. This regulating function, however, happens at the cost of profound alterations to the ocean’s physics and chemistry that lead especially to ocean warming and acidification, and consequently sea-level rise. … The problem is that we know ocean warming is driving change in the ocean — this is well documented — but the consequences of these changes decades down the line are far from clear.”

The 13 warmest years for sea surface temperatures have all occurred since 1997, with 2015 the highest yet and eclipsing the previous record of 2014. Parallel to that, August 2016 was the 16th consecutive month that overall global temperatures were the highest on record.

How high and fast will the seas rise?

The continuing building up of heat portends a potentially catastrophic rise in sea level. Two papers published last year calculate that, because of the greenhouse gases already emitted, humanity has already committed itself to a six-meter rise in sea level, and a paper published earlier this year predicts that seas could rise “several meters” in 50 to 150 years.

A still more pessimistic National Oceanic and Atmospheric Administration scientist, Margaret Davidson (giving her personal opinion, a NOAA publicist stresses), says that sea level could rise by as much as three meters by 2050 to 2060, a faster rise than current projections. She cites studies being done on the West Antarctic ice sheet. It is important to remember that the scientific controversy centers on the speed of global warming, not its existence — 97 percent of climate scientists agree that human activity is causing global warming, according to a NOAA study that also found the highest levels of agreement correlate with higher levels of expertise.

A major problem is that global warming, as with the associated environmental problems, can’t be solved within the capitalism that has caused, and is accelerating, the problem. All incentives under capitalism are for more growth and thus more greenhouse-gas emissions, and there is no provision to provide new jobs for the many people who would be displaced should the heavily polluting industries in which they work were to be shut down in the interest of the environment. The private capital that profits from environmental devastation is allowed to externalize the costs onto society, an inequality built into the system. The concept of “green capitalism” is a dangerous chimera.

There is no alternative to a dramatic change in the organization of the global economy and consumption patterns. That means significant reductions in energy consumption, an impossibility within a system that requires constant, unending growth. The rosy predictions of magical technology that will allow business as usual while scrubbing the atmosphere of new greenhouse gases, relied upon in the Intergovernmental Panel on Climate Change report that was in turn the basis for the Paris climate summit pledges, are not realistic, environmentalists say, and thus an illusion. Earth’s environment is crossing multiple points of no return — business as usual is impossible.

If we are to be serious about reversing global warming and repairing the environment, we have to create an economic system based on human need that is stable as a steady-state system and under democratic control, rather than our present authoritarian system that is designed to maximize private profit. That is necessary for economic and political reasons, but the environmental crisis adds another dimension. Otherwise, we “will sleepwalk ourselves into a nightmare, where no level of conservation action in the future will be enough,” in the concluding words of the “Explaining Ocean Warming” report. The task is enormous, but the consequences are even bigger.

No planet for optimists: Coastal flooding may come sooner than we fear

When it comes to global warming, what else don’t we know? What science does know, and what it can infer from studying archeological records, already makes anybody who thinks the long-term habitability of Earth is more important than short-term profits very worried.

One detail that may have been under-appreciated is meltwater. Melting ice sheets, especially in Greenland and Antarctica, is well understood to raise the sea level. But the effects might not be simply the additional water added to the oceans. In this scenario, the melted freshwater will additionally increase warming, thereby creating a feedback loop that will accelerate the loss of polar ice sheets, thus accelerating the rate of sea-level rise. How fast? Fast enough that the sea level could rise “several meters” in 50 to 150 years.

This sobering prediction of what might happen without a drastic reduction in greenhouse-gas emissions is the conclusion of 19 climate scientists from the United States, France, Germany and China who studied the effect of growing ice melt from Greenland and Antarctica through the use of climate simulations, paleoclimate data and modern observations. The paper, published in Atmospheric Chemistry and Physics and led by James Hansen, concludes that swift action is necessary in the face of a “global emergency.”

Predictions of a future catastrophic rise in the oceans, threatening to drown many of the world’s biggest cities, are by now far from novel. Two other recent papers conclude that humanity has already committed itself to a six-meter rise in sea level because of the greenhouse gases already thrown into the atmosphere and the retention and later slow release of much of those gases by the world’s oceans. A study in the journal Science estimates that more than 444,000 square miles of land, where more than 375 million people live today, would be inundated by such a rise.

Compare that to the complacency of the world’s governments at the Paris Climate Summit in December 2015. Despite a thunder of plaudits from the corporate media, the governments committed themselves to goals that, even if achieved, would lead to a global temperature rise of nearly 3 degrees Celsius by 2100, with further increases beyond that. That is far beyond the goal of 1.5 degrees set at the summit. But even the summit’s actual modest goals are not necessarily attainable because peer pressure is the primary mechanism to induce compliance; there are no binding legal agreements.

Feedback loops accelerate ice-sheet melting

The Atmospheric Chemistry paper says that sea level was at times six to nine meters higher than today approximately 115,000 years ago when the average global temperature “probably was only a few tenths of a degree warmer than today.” Ice-sheet stability may be a key to understanding rapid sea-level rise, the authors write.

The injection of added freshwater into the oceans from faster ice-sheet melting reduces the mixing of ocean waters, causing warmer water to remain at lower depths and thus making warmer water more available to melt the remaining ice shelves. This additional impact of meltwater on the global climate and its feedbacks had not been appreciated before, the authors write. They summarize this as follows:

“Our principal finding concerns the effect of meltwater on stratification of the high-latitude ocean and resulting ocean heat sequestration that leads to melting of ice shelves and catastrophic ice sheet collapse. Stratification contrasts with homogenization. Winter conditions on parts of the North Atlantic Ocean and around the edges of Antarctica normally produce cold, salty water that is dense enough to sink to the deep ocean, thus stirring and tending to homogenize the water column. Injection of fresh meltwater reduces the density of the upper ocean wind-stirred mixed layer, thus reducing the rate at which cold surface water sinks in winter at high latitudes.”

Existing models, including the authors’ own, underplays this mixing effect, the paper states, and thus anthropogenic warming “may be even more imminent than in our model.” Regardless of the exact timing, a tipping point will be reached:

“If the ocean continues to accumulate heat and increase melting of marine-terminating ice shelves of Antarctica and Greenland, a point will be reached at which it is impossible to avoid large-scale ice sheet disintegration with sea level rise of at least several meters. The economic and social cost of losing functionality of all coastal cities is practically incalculable.”

What might happen if the global temperature rises 2 degrees C. from pre-industrial levels? The possibilities are:

“Continued high fossil fuel emissions this century are predicted to yield (1) cooling of the Southern Ocean, especially in the Western Hemisphere; (2) slowing of the Southern Ocean overturning circulation, warming of the ice shelves, and growing ice sheet mass loss; (3) slowdown and eventual shutdown of the Atlantic overturning circulation with cooling of the North Atlantic region; (4) increasingly powerful storms; and (5) non-linearly growing sea level rise, reaching several meters over a timescale of 50–150 years. These predictions, especially the cooling in the Southern Ocean and North Atlantic with markedly reduced warming or even cooling in Europe, differ fundamentally from existing climate change assessments.”

A cold and arid Europe

The authors cite evidence that at the end of the interglacial period in which sea level was believed to be six to nine meters higher than today, there was a dramatic cooling in northern Europe, estimated at 3 degrees C. in summer and 5 to 10 degrees in winter in southern Germany, accompanied by four centuries of arid weather and a decline in trees. During the period of sea-level rise, the North Atlantic is also believed to have suffered from more severe storms, with archeological evidence from Bermuda and the Bahamas used as evidence.

As a consensus for global warming emerges, there is less certainty that capping global temperature increase at 2 degrees would be “safe”; thus the Paris Climate Summit’s surprise conclusion to set a goal of a 1.5-degree limit. To achieve such a goal, however, would, as noted above, require cuts to greenhouse-gas emissions far beyond anything pledged. The studies indicating that humanity has already committed itself to a six- to nine-meter sea-level rise imply that temperatures will rise past 1.5 degrees as greenhouse gas-generated heat trapped by the oceans is slowly released into the atmosphere over many decades, if not centuries.

There is no alternative to a massive change to industrial activity — no amount of re-forestation can come close to canceling out the effect of industrial activity.

The Atmospheric Chemistry paper concludes with this sober assessment:

“There is a possibility, a real danger, that we will hand young people and future generations a climate system that is practically out of their control. We conclude that the message our climate science delivers to society, policymakers, and the public alike is this: we have a global emergency. Fossil fuel CO2 emissions should be reduced as rapidly as practical.”

Unfortunately, we live in an economic system that requires constant growth and offers no alternative work for those whose jobs would be eliminated were we to shut down the most polluting industries. In one of his novels, Arthur C. Clarke wrote of a 23rd century world that was finally eliminating the clutter and pollution of the 20th century. Sad to say, the late science fiction master was overly optimistic.

Business as usual at Paris summit won’t stop global warming

The bottom line of the Paris Climate Summit is this: The world’s governments say they agreed to hold the global temperature increase to 1.5 degrees Celsius, but in actuality committed to nearly double that. A potential runaway global warming still looms in the future.

The surprise of the summit, officially known as the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, or COP 21, was the decision to set a goal of limiting the increase in temperature to 1.5 degrees above pre-industrial levels, instead of the previous target of 2 degrees. This was done at the behest of Pacific Island countries that might be submerged with a 2-degree rise, and the new, more ambitious target, if achieved, would provide a greater margin of error as a 2-degree rise is widely believed to be the limit at which catastrophic damage can be avoided.

How is the new goal to be achieved? Article 4 of the Paris Agreement, reached on December 12, states:

“In order to achieve the long-term temperature goal [of 1.5 degrees], Parties aim to reach global peaking of greenhouse gas emissions as soon as possible, recognizing that peaking will take longer for developing country Parties, and to undertake rapid reductions thereafter in accordance with best available science, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century, on the basis of equity, and in the context of sustainable development and efforts to eradicate poverty. …

Each Party’s successive nationally determined contribution will represent a progression beyond the Party’s then current nationally determined contribution. … Developed country Parties should continue taking the lead by undertaking economy-wide absolute emission reduction targets. Developing country Parties should continue enhancing their mitigation efforts, and are encouraged to move over time towards economy-wide emission reduction or limitation targets in the light of different national circumstances.”

What mechanisms will be created to ensure that the “Parties” (national governments) to carry out these plans? They “shall” report their progress, “shall undergo a technical expert review” (article 13) and discuss their progress five years from now (article 14). Governments will develop technology (article 10) and will “build mutual trust” through “transparency” (article 13).

In other words, peer pressure is the mechanism. There are no binding legal agreements requiring any country to achieve the reductions in greenhouse-gas emissions pledged for the Paris Climate Summit.

Pledges equate to a tweak, not a reversal

A further problem is that should all the pledges actually be met, the increase in global temperatures will be about 2.7 degrees, according to Climate Action Tracker. The group, comprised of four research organizations that produce independent scientific analyses, calculates that fulfillment of the national pledges would result in an increase in the global temperature of 2.2 to 3.4 degrees C. (with a median of 2.7) by 2100, with further increases beyond that. Although Climate Action Tracker notes that this potential rise is less drastic than the nearly 4-degree rise that the world had been on course for prior to the Paris commitments, what has been accomplished is merely to slow the increase in greenhouse-gas emissions.

The world’s governments have set various goals for reducing emissions by 2025 or 2030, with the European Union’s pledge of a 40 percent cut by 2030 the most ambitious among the biggest greenhouse-gas contributors. But the later that greenhouse-gas emissions are brought under control, the more difficult it will be to cap global warming at 1.5 or 2 degrees. A Climate Action Tracker analysis says:

“The need to fill in the gap between the projected [pledged] emissions levels in 2025 and the levels necessary to limit global warming to below 2°C means significantly more rapid, and costly, action would be needed compared to a situation where more ambitious targets for 2025 were adopted and where governments took immediate action now to achieve them. … Annual decarbonisation rates of 3-4%, which would be needed to catch up from 2025 [pledge] levels, are feasible, but the available modeling results indicate that such a reduction would result in much higher costs, more disruption, and more challenges than if action starts now and continues in a smooth way.”

The Intergovernmental Panel on Climate Change (IPCC) report issued last year foresees a rise in greenhouse-gas emissions for years to come, to above 450 parts per million, before falling to 450 ppm by 2100, which the report says is necessary to hold the global temperature rise to 2 degrees. Unfortunately, the IPCC report relies on several technological breakthroughs, including capture and sequestration of carbon dioxide, which is not yet close to being feasible.

In an analysis of the summit, Ian Angus and Phil Gasper explain this leap of faith:

“Almost all of the scenarios that show an increase of less than two degrees by 2100 require, first, much greater emissions reductions than anyone is proposing in the next 30 years. And then, after 2050, they require ‘negative emissions.’ That is, there would have to be some technology invented that takes carbon dioxide out of the air, and no such technology exists. And if it is invented, no one can say how it would function on a global scale, or whether it will be safe. It’s pure fantasy, and we can’t depend on fantasy.”

Worse, not all countries have necessarily even pledged to reduce their emissions. Writing in Climate & Capitalism, Jonathan Neale calculates that several countries, including China, India and Russia, have merely pledged to slow the rate of their increases in greenhouse-gas emissions, and other governments, such as the United States, European Union, Canada and Australia, have agreed to cut their emissions by one percent per year. He writes:

“[C]ountries like India and China promise to cut emissions in terms of carbon intensity. Carbon intensity is the amount of carbon in fossil fuels that is needed to produce the same amount of work. Carbon intensity has been going down in the United States for a hundred years. It is going down all over the world. This is because we learn to use coal, oil and gas more efficiently, just like we learn to use everything else in industry more productively. So a promise to cut carbon intensity is a promise to increase emissions.”

Pollution as a market commodity

Short-term profits are still given priority over the long-term health of the environment. One manifestation of this is that governments continue to rely on “cap and trade” schemes that make pollution a market commodity. Too many credits are provided for free, and as a result the prices for them have fallen drastically; and politically influential industries are often exempted, even if they are among the most polluting.

All the incentives in capitalism are for more growth, and the accumulation of power that accrues to corporations that grow the most enable large industry to bend laws and regulations to their liking. Stagnation in a capitalist economy causes persistent unemployment and other problems, as the past several years amply demonstrate. And that is before we get to the problem that nobody will be offering displaced workers new jobs should the polluting industries they work in be shut down or curtailed. Industry can say that any new restrictions on it will cost jobs, and rally working people behind them on that basis.

Professors Angus and Gasper, in their analysis of the Paris Climate Summit, stress the necessity of environmentalists working with labor:

“The fact is that workers don’t want to lose their jobs. Here in Canada, we have the phenomenon of people from some of the poorest parts of the country going to work in the Alberta Tar Sands. After six months or a year, they can go home, to a place where there are no jobs, and buy a house or a car, or pay off their debts. Telling those people ‘Don’t do that because you’re causing greenhouse gas emissions’ is just absurd. It’s a guaranteed way to turn working people against the environmental movement.

Now again, unfortunately, we see a lot of that. I’ve heard greens argue that we shouldn’t even try to reach oil sands workers because they’re just part of the colonial-settler assault on First Nations territory. Which is true–so we have to win them away from doing that, not force them into a firmer alliance with their bosses. We need to find ways to work with the labor movement around the whole concept of a ‘just transition.’ That concept has come out of the international labor movement–that we realize the change in the economy is going to result in lost jobs, and nobody should suffer as a result. There should be jobs or full pay, free retraining and so on.”

A worthy goal indeed. But could such a program be accomplished under capitalism? It does not seem so. Professors Angus and Gasper note that such a goal won’t be won without a strong movement. But as capitalism is a system designed for private profit, achieved through the exploitation of working people, a strong movement would have to push beyond it, to a more humane, rational economic system.

Another factor to contend with is that the goals of the Paris Climate Summit, inadequate as they may be, will be null and void should the Trans-Pacific Partnership and/or the Transatlantic Trade and Investment Partnership be approved. These multi-national “free trade” agreements would enable corporations to sue to overturn laws that protect the environment, and provide further incentives for production to be moved around the world with an accompanying increase in fossil fuels used for transporting components and finished goods across longer supply chains. TPP rules codifying benefits for multi-national corporations are written in firm language, but there is no such language for environmental or health protections. The TTIP’s language will likely be no better. The TPP does not mention global warming once in its text.

The Paris Climate Summit has been an exercise in feeling good, with the world’s corporate-media reporters at risk of sore arms from all the back pats they are giving. A future world of uncontrollable climate change, with agricultural patterns disrupted and species dying at accelerating rates, won’t feel good, however. Business as usual won’t save the future; only mass mobilization on a global scale can.

Earning a profit from global warming

As evidence mounts that a warming world is hurtling toward the point of no return, the plan of the world’s governments is to make adjustments to the ability of corporations to profit from polluting. Short-term profits continue to be elevated above the long-term health of the environment.

There does seem to be a new sense of governmental urgency ahead of the Paris climate summit scheduled for December, with several governments announcing new proposed reductions in future greenhouse-gas emissions. But is it already too late? Two scientific studies issued this year suggest that so much carbon dioxide already has been thrown in the air that humanity may have already committed itself to a six-meter rise in sea level. A separate 2015 study, prepared by 18 scientists, found that the Earth is crossing several “planetary boundaries” that together will render the planet much less hospitable.

The Paris climate summit, officially known as the 21st Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change, or COP 21, has set itself the goal of “achiev[ing] a new international agreement on the climate, applicable to all countries, with the aim of keeping global warming below 2°C.” Representatives of the world’s governments will meet with an intention of setting goals for combatting global warming.

Thus far, however, the world’s governments have done little, relying on “cap and trade” schemes that make pollution a market commodity, setting goals for far in the future, and raising false hopes that “green capitalism” will magically save the day with shiny techno-fixes that will allow business as usual to continue. Worse yet, the same governments that claim to be taking steps toward reigning in pollution and greenhouse-gas emissions are negotiating destructive “free trade” agreements like the Trans-Pacific Partnership and Transatlantic Trade and Investment Partnership that will allow corporations to eliminate laws that protection the environment.

There are no free lunches, however, and definitely no free planets.

“Free trade” is not free for the environment

Already, under the North American Free Trade Agreement, laws protecting people and the environment from toxic chemicals have been overturned. NAFTA is the starting point for The Trans-Pacific Partnership and similar secret deals, which will have still more draconian rules.

Maude Barlow of the Council of Canadians notes that measures to reduce greenhouse-gas emissions are no less susceptible to attack:

“Lawsuits totalling hundreds of billions of dollars have challenged environmental protection measures such as solar power programs, neurotoxin and additive bans, and the rejection of proposed mines. Canada, the most-sued state under NAFTA, is facing $2.6 billion in corporate challenges against legislation that restricts or bans carcinogenic additives in gasoline, lawn pesticides and fracking. Around the world, corporations have challenged governments over 600 times. With no way around these provisions, countries have been unable or unwilling to advance climate change legislation.”

“Free trade” agreements also contribute directly to global warming because they facilitate the transfer of production to the countries with the lowest wages and weakest regulation. Products are assembled from parts produced in multiple countries then shipped across oceans, greatly adding the environmental costs of transportation. This is not some natural phenomenon like the tides of the ocean, but rather are products of the competitive dynamics of capitalism.

Not wanting to upset this dynamic, or their benefactors, political leaders instead fiddle while the Earth burns, as the G7 leaders did when declaring their intention to commit themselves to a 40 to 70 percent reduction in greenhouse-gas emissions in 2050 and a complete phaseout in 2100. No government can bind a successor 80 years in the future, but it surely is easier to announce such a goal than to impose one scheduled to take effect when you might still be in office.

Those long-term targets mirror those of last year’s Intergovernmental Panel on Climate Change report, which set them with an eye toward holding greenhouse-gas concentrations in the atmosphere to 450 parts per million in 2100, and even there envisions a temporary rise above 450 ppm before falling late in the 21st century.

The Paris climate summit, scheduled to take place November 30 to December 11, is being billed as the last chance for the world’s governments to set interim goals that could prevent global temperatures from rising more than 2 degrees Celsius above the pre-industrial average, a level widely believed (perhaps optimistically so) to be the limit before runaway global warming results. Yet the Earth is already experiencing climatic changes of a speed never before seen in the geological record, with atmospheric carbon dioxide at 400 ppm.

Sure we’ll cut emissions — eventually

National global-warming commitments include these goals:

  • The United States has pledged to reduce greenhouse-gas emissions by 26 to 28 percent in 2025, relative to 2005 levels; instituted new national regulations on power-plant emissions; and announced a state-level cap-and-trade system whereby states, rather than enterprises, will trade pollution permits.
  • China intends to reach a peak in its greenhouse-gas emissions by 2030; will inaugurate a cap-and-trade system in 2017; and pledges to have 50 percent of its new buildings meet “green” standards by 2020.
  • The European Union’s goal is a 40 percent cut in emissions in 2030, relative to 1990. The centerpiece of E.U. efforts is a failed cap-and-trade system that will not be reformed until 2021.
  • Brazil said it would cut emissions by 37 percent in 2025, relative to 2005, and intends to achieve a 43 percent reduction by 2030. Brazil intends to generate 20 percent of its electricity from non-hydropower renewables by 2030 and pledges to restore 30 million acres (120,000 square kilometers) of forests.
  • Canada has committed to cutting output of greenhouse gases by 30 percent in 2030, relative to 2005, but this includes international “offsets” and fails to address the Alberta tar sands. On a provincial level, Ontario and Québec will participate in a cap-and-trade system.
  • Japan intends to reduce emissions by 26 percent in 2030, relative to 2013 (the equivalent to 18 percent below 1990 levels by 2030), reductions that would include international “offsets” and “credits” for forest management.
  • India has pledged to reduce the intensity of its emissions 33 to 35 percent in 2030, relative to 2005, and to produce 40 percent of its electricity from non-fossil fuel sources by that year. This goal, however, is a commitment to only slow the rate of emissions rather than cut them.
  • Australia has committed a 26 to 28 percent cut in emissions, relative to 2005, reductions to be achieved in part through land-use changes and forestation. But the current coalition government has repealed the Clean Energy Future Plan, seen as a step backward.

None, however, are judged by environmentalists to be making adequate progress toward these goals.

Cap-and-trade a subsidy for polluters

There has been a flurry of approval over Chinese President Xi Jinping’s September 25 announcement that China would institute a cap-and-trade program. Such schemes are often promoted by North American liberals and European social democrats. But these do virtually nothing to reduce greenhouse gases while allowing corporations to profit from pollution.

The European Union cap-and-trade program, 10 years old and the world’s biggest, has been a complete failure. Europe’s emissions trading system mandates that an enterprise that emits carbon dioxide must hold certificates equal to their emissions, and can buy or sell them from other corporations. But 43 percent of these certificates are issued for free, a subsidy for carbon emitters.

The targeted carbon trading price was €30 per metric ton, but because far too many certificates were issued, they trade at between €6 and €8. The E.U. proposes to reduce the number of free certificates, but not until 2021. Moreover, although the number of industries eligible for free carbon certificates will be reduced to 50 from 177, wine makers and tomato growers will no longer be eligible for the freebies, but cement factories, aluminum plants and others in heavy industry will still get them, according to Deutsche Welle.

The watchdog group Carbon Market Watch issued this caustic summation:

“[T]he EU Emissions Trading System review proposes to increase pollution subsidies to industry to at least €160 billion after 2020. … After more than a decade, the EU’s main climate instrument still lacks the teeth to make the polluter pay and drive emission reductions. Today’s proposal serves the interests of Europe’s largest polluters at the expense of the climate and taxpayers’ money.”

Carbon Market Watch reports that industries representing about 95 percent of industrial greenhouse-gas emissions will continue to receive free pollution permits after 2020. Despite the current excessive number of tradable credits — the reason for the plunge in pricing — there will be no cancelations of any of them despite calls by environmental activists for the number of credits to be diminished. Threats by industrialists to move out of Europe helped shape the “reforms.”

Industry had already shaped the cap-and-trade plan from the beginning. Richard Smith, in his paper Green capitalism: the god that failed, recounts the experience of former German environment minister Jürgen Tritten, a Green Party official:

“Mr. Tritten recalled a five-hour ‘showdown’ with [Social Democrat] Wolfgang Clement, then economy minister, in which he lost a battle to lower the overall limit. Clement reproached the Greens saying that ‘at the end of their policy there is the de-industrialization of Germany.’ Similarly, in confrontation with the Federation of German Electricity Companies, ‘good sense triumphed in the end’ and industry won: whereas under EU commitments, German electricity companies were supposed to receive 3 percent fewer permits than they needed to cover their total emissions between 2005 and 2007, which would have obliged them to cut emissions by that amount, instead the companies got 3 percent more than they needed – a windfall worth about $374 billion at that time.”

Offsets don’t necessarily offset emissions

A French plan to go beyond cap-and-trade schemes with a tax on carbon was ultimately declared unconstitutional because, among other problems, it would have exempted more than 1,000 of France’s biggest polluters, Professor Smith said.

An additional weakness of cap-and-trade schemes is that some allow “offsets,” whereby companies can buy emission credits from outside the program to “offset” emissions above the allowable level. But the offset is not necessarily real, and often is counted twice, by the enterprise buying the credit and by the entity providing the offset. Food & Water Watch explained this slight of hand:

“Through offsets, a company can pay to theoretically prevent emissions outside of the cap, instead of reducing emissions at the source. For example, a power plant in California could pay for a section of forest to not be cut down in Oregon. This would count toward the polluter’s required reductions even though emissions are not reduced in California but are in theory prevented in Oregon. … The supposed benefits that offsets are intended to provide often fail to materialize. … [I]n reality, [offsets] allow polluters to substitute unverifiable reductions for real reductions.”

Business as usual isn’t possible: The atmospheric content of carbon dioxide continues to rise. Less reliance on fossil fuels and more reliance on renewable fuels is certainly a strong step in the right direction, but because many renewables also produce considerable greenhouse gases, they are incapable of reversing global warming by themselves.

There is no escaping that humanity must consume much less, an impossibility under a system, capitalism, that demands continual growth, whose incentives are for more consumption, and that enforces a competitive race to the bottom that includes the ongoing corporate globalization that systematically moves production to low-wage havens.

To stave off further global warming, and avoid the massive disruptions it promises, requires nothing less than an entirely new economic system, one that provides for human need under community control rather than private profit under the control of industrialists and financiers. Let us not sugar-coat this: Such wrenching changes will come with considerable costs. But the costs of business as usual will be immeasurably greater from rising sea levels, mass extinctions, droughts and chaotic weather. Our descendants are not likely to believe short-term profits for a few now will be a fair exchange for an unlivable planet for the many then.

We may have already committed ourselves to 6-meter sea-level rise

Even if humanity were to stop throwing carbon dioxide and methane into the atmosphere today, a catastrophic rise in sea levels of six meters may be inevitable. Two previous prehistoric interglacial periods, in which the carbon dioxide content of the atmosphere was believed to be about what it is today, resulted in dramatic rising of the oceans.

High-latitude ice sheets are melting, and given that global warming is most pronounced in the Arctic, it may already be too late stop a rise in sea levels that would flood out hundreds of millions around the world. Two new papers, the latest in a series of scientific studies, paint a picture considerably less rosy than conventional ideas that major damage can still be avoided.

One of these papers, a nine-scientist report led by geologist Andrea Dutton at the University of Florida published in the journal Science, found that modest rises in global temperatures in the past led to sea levels rising at least six meters. She summarized the findings this way to Climate Central:

“Even if we meet that 2°C target, in the past with those types of temperatures, we may be committing ourselves to this level of sea level rise in the long term. The decisions we make now about where we want to be in 2100 commit us on a pathway where we can’t go back. Once these ice sheets start to melt, the changes become irreversible.”

Professor Dutton was referencing the widely held belief that catastrophic damage can be avoided if global warming is held to no more than 2 degrees C. from pre-industrial levels. The “permissible” level may be less than that, however. More sophisticated “sea-level reconstructions” through interdisciplinary studies of geological evidence and better understanding of the behavior of ice sheets enabled the paper’s authors to infer that temperatures only slightly higher than what we are experiencing today upset the climatic balance. A summary of the paper concludes:

“[D]uring the last interglacial — a warm period between ice ages 125,000 years ago — the global average temperature was similar to the present and this was linked to a sea-level rise of 6-9 meters, caused by melting ice in Greenland and Antarctica. Around 400,000 years ago, when global average temperatures were estimated to be between 1 to 2°C higher than preindustrial levels, sea levels reached 6-13 meters [higher.]”

“Small” changes have big consequences

More alarming, the level of carbon dioxide in the atmosphere then was lower than it is today. Although geological forces pushing and pulling Earth’s surface can’t be precisely calculated, and thus introduce uncertainty in the actual level of the oceans in the geologic record, the greater uncertainty lies at the higher level of estimates. The paper’s summary said:

“Noticeably, during these two periods, carbon dioxide in the atmosphere remained around 280 parts per million (ppm). The scientists  also looked at sea level during the Pliocene, three million years ago, when carbon dioxide levels reached around 400 ppm — similar to today’s levels. They hypothesized that sea level was at least 6 metres higher than today and potentially substantially higher. … While the global average temperature rises of 1 to 3°C seem small, they were, like today, linked with magnified temperature increases in the polar regions which sustained over many thousands of years.”

A second paper, State of the Climate in 2014, reports that Arctic sea-surface temperatures are rising faster than overall global temperatures, ice caps across the Northern Hemisphere continue to shrink, record high permafrost temperatures are being recorded in northern Alaska and melting of the Greenland ice cap is accelerating. The paper, a collaboration of 413 scientists from 58 countries, reports that, even if greenhouse gases were frozen at current levels, the oceans would continue to warm for centuries and thus lead to rising sea levels.

Carbon dioxide thrown into the air stays in the atmosphere for a long time and warming oceans will retain added heat and transfer that back to the atmosphere. This is already leading to warming oceans, State of the Climate reports:

“Increasing concentrations of greenhouse gases are preventing heat radiated from Earth’s surface from escaping into space as freely as it used to; most of the excess heat is being stored in the upper ocean. As a result, upper ocean heat content has increased significantly over the past two decades.”

The Science and State of the Climate papers back previous studies that conclude “there is no going back” — the excess heat stored in oceans will be released back into the atmosphere for centuries to come — and that Earth is crossing multiple points of no return.

Ice melts in front of our eyes

Two worrisome trends are that the eight lowest Arctic Ocean sea-ice extents have all occurred in the past eight years, and that the extent of the melting of the Greenland ice sheet during summer 2014 was faster than the 1981-to-2000 average 90 percent of the time. Antarctic ice is not yet showing accelerated melting, State of the Climate reports, but the paper does note that short-term extremes in temperatures have become more frequent on the continent.

Nor does that mean that all is well in Antarctica. Two scientific papers published in 2014 suggest the West Antarctic ice sheet has become dangerously weakened. One finds that a “large sector of the West Antarctic ice sheet … has passed the point of no return” and the other finds that the ice sheet has become sufficiently unstable to possibly collapse in as few as 200 years. That is a long time by ordinary human standards, but very brief in geological terms, and would add greatly to rising sea levels.

So what would a six-meter increase in ocean levels mean? More than 440,000 square miles (1.14 million square kilometers), where 375 million people, would go under water, according to Climate Central.

The current path humanity is walking is to throw more greenhouse gases into the atmosphere. Current plans by political leaders to reduce greenhouse-gas emissions by 2050 and completely by 2100 are woefully inadequate, but even those goals will be difficult to achieve. The metabolism of capitalism, and all its incentives, is for more growth and thus more anthropogenic warming. And although reversing global warming is impossible without reducing consumption, that, too, is impossible under capitalism because a typical advanced capitalist country 60 to 70 percent of the economy is accounted for by household spending.

Because of the growth imperative of capitalism — the need to grow or die forces enterprises into never-ending innovations to cut costs — economic growth of 2.5 percent is necessary to maintain the unemployment rate where it is and “substantially stronger growth than that” is necessary for a rapid decrease, according to a former White House Council of Economic Advisers chair, Christina Romer. Capitalism will not guarantee new jobs for those made unemployed by closing down polluting industries, adding incentives to maintain them. “Free trade” agreements accelerate global warming because supply lines are stretched around the world and production is moved to the places with the lowest wages and weakest regulations. And as conventional sources of energy are depleted, more extreme measures are taken, including the exploitation of tar sands, adding still more greenhouse gases.

Our descendants are not likely to believe that short-term corporate profits and unsustainable consumption were a fair tradeoff for a world left much less habitable.

G7 leaders fiddle while Earth burns

The G7 governments saying they will phase out fossil fuels by 2100 isn’t closing the barn door after the horse has left. It is declaring an intention to consider closing the barn door after waiting for the horse to disappear over the horizon. It is okay to be feel underwhelmed by this.

The Group of 7 summit held earlier this month in Germany, representing seven of the world’s largest economies, ended with a declaration that these governments would commit themselves to a 40 to 70 percent reduction in greenhouse-gas emissions and a complete phaseout in 2100, and an invitation for “all countries to join us in this endeavor.” A communiqué issued after the summit declared:

“We commit to doing our part to achieve a low-carbon global economy in the long-term including developing and deploying innovative technologies striving for a transformation of the energy sectors by 2050. … To this end we also commit to develop long-term national low-carbon strategies.” [page 17]

The G7 governments say they are acting under the impetus of last year’s Intergovernmental Panel on Climate Change report and in anticipation of next December’s Climate Change Conference in Paris. In the conception of the IPCC report, greenhouse-gas emissions should be 40 to 70 percent lower globally in 2050 than in 2010 and “near zero” in 2100 to achieve a goal of holding greenhouse-gas concentrations in the atmosphere to 450 parts per million in 2100. Even that level is a substantial increase above the current level of 404 parts per million, at which the Earth’s climate is already undergoing dramatic changes.

The IPCC report, prepared by scientists from around the world but apparently watered down by the world’s governments, promises that mitigating global warming will be virtually cost-free and require no fundamental change to the world’s economic structure. Alas, there are no free lunches — the IPCC report’s insistence that techno-fixes will magically take care of carbon buildup, allowing humanity to continue the path it has been on since the dawn of the Industrial Revolution, is dangerously unrealistic.

So what do the G7 governments have in mind? Their communiqué says they will increase the number of people in developing countries who have access to insurance, increase developing countries’ access to renewable energy and raise funds “from private investors, development finance institutions and multilateral development banks.” [pages 15-16] Try to contain your excitement when you read the G7 prescription for combating global warming:

“We will continue our efforts to provide and mobilize increased finance, from public and private sources. … We recognize the potential of multilateral development banks in delivering climate finance and helping countries transition to low carbon economies.” [page 15]

It may already be too late

Before we delve into the idea that the World Bank, funder of gigantic greenhouse-gas belching, polluting projects around the world, is the cure for global warming, and before we contemplate the idea that we can bind the policies of governments eight decades in the future, let us ask what actually needs to be done to prevent the climate from spiraling into a feedback loop that will accelerate species die-offs and dangerously disrupt agriculture and water supplies. The U.S. government’s climate agency, the National Oceanic and Atmospheric Administration, issued a study in 2009 that flatly concluded “there’s no going back.” The study, led by NOAA senior scientist Susan Solomon, found:

“[C]hanges in surface temperature, rainfall, and sea level are largely irreversible for more than 1,000 years after carbon dioxide (CO2) emissions are completely stopped. … ‘It has long been known that some of the carbon dioxide emitted by human activities stays in the atmosphere for thousands of years,” Solomon said. “But the new study advances the understanding of how this affects the climate system.’ ”

Carbon dioxide thrown into the air stays in the atmosphere for a long time, warming oceans will retain added heat and transfer that back to the atmosphere, and we have yet to experience the full effect of greenhouse gases that have already been emitted. Global sea-level rises and major disruption to rain patterns will effect billions of people. The NOAA study said:

“If CO2 is allowed to peak at 450-600 parts per million, the results would include persistent decreases in dry-season rainfall that are comparable to the 1930s North American Dust Bowl in zones including southern Europe, northern Africa, southwestern North America, southern Africa and western Australia.

The study notes that decreases in rainfall that last not just for a few decades but over centuries are expected to have a range of impacts that differ by region. Such regional impacts include decreasing human water supplies, increased fire frequency, ecosystem change and expanded deserts. Dry-season wheat and maize agriculture in regions of rain-fed farming, such as Africa, would also be affected.”

A Massachusetts Institute of Technology paper, lamenting the widespread conviction that global warming can be reversed quickly when and if it is decided to do so, notes such beliefs are in violation of basic physics. The paper’s abstract says:

“[W]ait-and-see policies erroneously presume climate change can be reversed quickly should harm become evident, underestimating substantial delays in the climate’s response to anthropogenic forcing. … [Greenhouse-gas] emissions are now about twice the rate of GHG removal from the atmosphere. GHG concentrations will therefore continue to rise even if emissions fall, stabilizing only when emissions equal removal. In contrast, results show most subjects [of an MIT study] believe atmospheric GHG concentrations can be stabilized while emissions into the atmosphere continuously exceed the removal of GHGs from it. These beliefs—analogous to arguing a bathtub filled faster than it drains will never overflow—support wait-and-see policies but violate conservation of matter.”

More heating even if we stopped today

A commentary published on RealClimate, a Web site published by working climate scientists, calculates that if greenhouse-gas concentrations were kept constant at today’s level, there would still be an increase in global temperatures of as much as 0.8 degrees Celsius — combined with the global warming already experienced, that is close to the 2-degree overall rise widely believed to be the outer limit to avoid catastrophic damage to Earth’s ecosystem. But to achieve even that equilibrium requires immediate, significant cuts to greenhouse-gas emissions. The commentary says:

“[C]onstant concentrations of CO2 imply a change in emissions — specifically an immediate cut of around 60 to 70% globally and continued further cuts over time.”

“Immediate” as in now, not decades in the future. The actual proposed cuts, in the near term, are far less than that range, and less than initially meets the eye. The baseline of measurement is being shifted, for example, so that the benchmark against which the reductions are measured are higher than previously set. Environmental Defence Canada calculates that the Harper government’s switch to using 2005 rather than 1990 as the baseline reduces the goal by more than half. In a report, the group writes:

“The U.N. Framework Convention on Climate Change (1992) and the Kyoto Protocol (1997) both used 1990 as the reference or base year. Most countries still use 1990 as the base year but some have started using more recent base years. Since the Copenhagen summit in 2009, Canada has been using 2005 as a base year. This makes comparison between targets more difficult. It also makes targets look stronger than they are since Canada’s carbon pollution increased significantly between 1990 and 2005. For example, the Canadian government’s pledge to reduce emissions by 30 per cent below 2005 by 2030 is actually less than half as strong … when expressed using 1990 as the base year.” [page 3]

Emissions from the Alberta tar sands have increased almost 80 percent since 2005 and the Harper government has every intention of boosting tar sands production as much as possible, including plans for multiple pipelines, while equating environmentalists with terrorists. Environmental Defence Canada notes that the Harper government has no intention of regulating tar sands oil and flatly declares Canada’s post-2020 target “the weakest in the G7 to date.”

The potential global warming just from the Alberta tar sands is so large that the U.S. environmental scientist James Hansen believes it will be impossible to stop runaway global warming should that oil be burned.

Assigning contributions isn’t straightforward

The point here isn’t to single out Canada. But its cumulative greenhouse-gas emissions since the dawn of the Industrial Revolution is the ninth highest in the world, a ranking likely to rise if plans of current oil and gas companies come to fruition. So the argument sometimes made that Canada isn’t a significant contributor to global warming because of its small population isn’t true. The United States, not surprisingly, is easily the biggest culprit, having emitted 29 percent of the world’s cumulative greenhouse gases, according to calculations by the World Resources Institute.

China ranks second, with nine percent of the world’s cumulative greenhouse-gas emissions, and the top 10 countries account for 72 percent. (Italy is the only G7 country not among the top 10.) But even here, it could be argued that China’s ranking deserves an asterisk. Western multi-national corporations have eagerly transferred production to China, particularly U.S. companies such as Wal-Mart and Apple. So much of those Chinese greenhouses gases are the responsibility of U.S. corporations. A paper led by Glen Peters of the Center for International Climate and Environmental Research in Oslo estimates that, in 2008 alone, the U.S. imported as much as 400 million tons of carbon dioxide in Chinese goods.

Regardless of source, global warming does not come without costs. The nonprofit organization DARA claims that global warming already causes 400,000 deaths per year, and that “the present carbon-intensive economy moreover is linked to 4.5 million deaths worldwide each year.”

Can the World Bank and International Monetary Fund realistically be part of the solution to global warming, as the G7 communiqué would have it? No! The World Bank has poured billions of dollars into dams, power plants and other projects that worsen global warming, and shows no sign of altering its indifference to environmental costs. The World Bank and IMF also promote neoliberalism and austerity programs around the world; immiserating people makes them more vulnerable, not less, to the stresses of global warming and pollution.

The amount of industrial carbon dioxide emissions thrown into the atmosphere from 1988 to 2014 is equal to all the emissions from 1751 to 1988, according to the Climate Accountability Institute. That continually rising rate of emissions is reflective of the ever more intensive pressures for growth capitalism imposes, and the continual movement of production to the places with the lowest wages and weakest environmental laws imposed by capitalist competition, stretching supply chains ever longer, is itself a contributor to global warming.

The G7 communiqué is nothing more than wishful thinking that no real change is necessary. There are no free lunches: The world has to drastically reduce its consumption. As this is an impossibility under capitalism, another world is not only possible, it is necessary in the long run for our descendants to even have a livable world.
