Climate Change

Tripati AK, Roberts CD, Eagle RA. Coupling of CO2 and Ice Sheet Stability Over Major Climate Transitions of the Last 20 Million Years. Science 2009;326(5958):1394-7. http://science.sciencemag.org/content/326/5958/1394.full

The carbon dioxide (CO2) content of the atmosphere has varied cyclically between ~180 and ~280 parts per million by volume over the past 800,000 years, closely coupled with temperature and sea level. For earlier periods in Earth’s history, the partial pressure of CO2 (pCO2) is much less certain, and the relation between pCO2 and climate remains poorly constrained. We use boron/calcium ratios in foraminifera to estimate pCO2 during major climate transitions of the past 20 million years. During the Middle Miocene, when temperatures were ~3° to 6°C warmer and sea level was 25 to 40 meters higher than at present, pCO2 appears to have been similar to modern levels. Decreases in pCO2 were apparently synchronous with major episodes of glacial expansion during the Middle Miocene (~14 to 10 million years ago) and Late Pliocene (~3.3 to 2.4 million years ago).
 
Helmuth B, Gouhier TC, Scyphers S, Mocarski J. Trust, tribalism and tweets: has political polarization made science a “wedge issue”? Climate Change Responses 2016;3(1):1-14. https://climatechangeresponses.biomedcentral.com/articles/10.1186/s40665-016-0018-z

Background - Political polarization remains a major obstacle to national action on global climate change in the United States Congress, and acceptance of anthropogenic drivers strongly differs between Republicans and Democrats.

But has overall interest in science also become ingrained into partisan identity, even among national political figures tasked with making ostensibly science-based policy decisions? Social media outlets such as Twitter have become a popular means of exchanging information and of portraying a carefully crafted public image.

We analyzed the 78,753 unique Twitter accounts followed by U.S. senators to gauge their interests as well as the public images that their offices project to the public. In particular, we examined correlations between follows of science-related accounts and recent votes on a series of amendments defining the “sense of the Senate” on global climate change (GCC). Drawing from these social networks, we discuss how political polarization is strongly linked with the role that science - and climate science in particular - plays in the political process.

Results - Our analyses show that Twitter social networks reflect political affiliation and polarization, with Senate Republicans and Democrats belonging to distinct and semi-isolated sub-networks. Notably, while follows of science-related organizations were low overall, these sub-networks were characterized by very different levels of interest in science, with Senate Democrats three times more likely to follow science-related Twitter handles than Republicans.

This suggests that overt interest in science may partly define party identity. Hence, instead of being viewed as a neutral source of objective information, science may now be considered a special interest in U.S. politics. Notably, however, Republican senators who crossed party lines to vote “yea” on an amendment associated with the Keystone Pipeline bill stating that humans contribute to GCC are more similar to Democrats in their science follows than they are to their fellow Republicans.

Conclusions - Our results strongly suggest that overt interest in science may now primarily be a “Democrat” value. However, opportunities exist to inject scientific information into political discussion by targeting key individuals and organizations connected to both sides of the aisle.
 
The overarching climate goal of the Paris Agreement is to hold “the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels”.

This climate goal represents the level of climate change that governments agree would prevent dangerous interference with the climate system, while ensuring sustainable food production and economic development and is the result of international discussions over multiple decades.

Limiting warming to any level implies that the total amount of carbon dioxide (CO2) that can ever be emitted into the atmosphere is finite. From a geophysical perspective, global CO2 emissions thus need to become net zero.

About two thirds of the available budget for keeping warming to below 2 °C have already been emitted and increasing trends in CO2 emissions indicate that global emissions urgently need to start to decline so as to not foreclose the possibility of holding warming to well below 2 °C.

The window for limiting warming to below 1.5 °C with high probability and without temporarily exceeding that level already seems to have closed.

WHY HAS A DROP IN GLOBAL CO2 EMISSIONS NOT CAUSED CO2 LEVELS IN THE ATMOSPHERE TO STABILIZE?
Why Has a Drop in Global CO2 Emissions Not Caused CO2 Levels in the Atmosphere to Stabilize?

There’s a pretty simple reason why the recent stabilization in global emissions hasn’t caused CO2 levels to stabilize. The ocean and land sinks for CO2 currently offset only about 50 percent of the emissions. So the equivalent of 50 percent of the emissions is still accumulating in the atmosphere, even with stable emissions. To stabilize CO2 levels would require roughly an immediate roughly 50 percent cut in emissions, at which point the remaining emissions would be fully offset by the sinks, at least for a while.

Eventually, additional emissions cuts would be required because the sinks will slowly lose their efficiency as the land and ocean start to saturate. A permanent stabilization at current levels therefore requires both an immediate 50-percent cut as well as a slow tapering thereafter, eventually approaching zero emissions. The recent stabilization in emissions might be viewed as a very small first step toward the required cuts.
 
Can New York Be Saved in the Era of Global Warming?
http://www.rollingstone.com/politics/news/can-new-york-be-saved-in-the-era-of-global-warming-20160705

As Zarrilli knows better than anyone, Hurricane Sandy, which hit New York in October 2012, flooding more than 88,000 buildings in the city and killing 44 people, was a transformative event. It did not just reveal how vulnerable New York is to a powerful storm, but it also gave a preview of what the city faces over the next century, when sea levels are projected to rise five, six, seven feet or more, causing Sandy-like flooding (or much worse) to occur with increasing frequency. "The problem for New York is, climate science is getting better and better, and storm intensity and sea-level-rise projections are getting more and more alarming," says Chris Ward, the former executive director of the Port Authority of New York and New Jersey, the agency in charge of airports, tunnels and other transportation infrastructure. "It fundamentally calls into question New York's existence. The water is coming, and the long-term implications are gigantic."

Why Obama’s top scientist just called keeping fossil fuels in the ground ‘unrealistic’
Why Obama’s top scientist just called keeping fossil fuels in the ground ‘unrealistic’



Morning Consult also reported that Holdren stated, “The notion that we’re going to keep it all in the ground is unrealistic. We are still a very heavily fossil-fuel dependent world.”

“When asked whether it was feasible to leave all the remaining fossil fuels in the ground, Dr. Holdren noted that it is not, because the U.S. — and the world — still depend on fossil fuels for more than 80 percent of all the primary energy we use,” said White House spokeswoman Lindsey Geisler said in an email. “It’s not practical or affordable to replace the huge, fossil-fuel infrastructure with nuclear and renewables overnight, no matter how badly we may want to. As a result, the U.S. will be using fossil fuels for decades to come, albeit, one hopes, with the share of non-fossil supplies increasing over time.”

In one sense, Holdren’s remarks could be viewed as simply stating what’s already known. Indeed, wind and solar provided a little over 5 percent of U.S. electricity last year. Meanwhile, a key driver of the recent U.S. trend toward “cleaner” energy has not been burning less fossil fuels, but rather the swapping of one fossil fuel for another.

More specifically, very cheap natural gas prices, which have driven fracking and the exploitation of huge new “unconventional” shale gas reserves, has led to a shift in how we get power. More and more, utility companies are switching away from burning coal for electricity and toward burning gas. According to the EIA, 2016 is likely to be the first year in which the country as a whole gets more of its electricity from gas than from coal.

And that has significant greenhouse gas emissions implications, as natural gas burns cleaner than coal and only produces about half as much carbon dioxide emissions per unit of energy.

“Facts are facts: America is leading the world in oil and natural gas production and in lowering carbon emissions, which are at 20-year lows, because of clean-burning natural gas,” said Eric Wohlschlegel, director of media relations and communications at the American Petroleum Institute, regarding the Holdren statement. “American voters support increased oil and natural gas production. They understand that the wind doesn’t always blow and the sun doesn’t always shine and that an all of the above energy strategy is needed to power our future. Keep-it-in-the-ground tactics aimed at misleading the public present a false choice, especially when there’s overwhelming support for American energy production.”

In the transportation sector, meanwhile, cleaner options like electric cars or cars that run on high volumes of biofuels are even further away from achieving market dominance than wind and solar are in the electricity sector. So when Holdren reportedly called the “keep it in the ground” movement “unrealistic,” it was simply a statement that there is no way we are going to get off fossil fuels in the near term.

The 2015 Paris Agreement aims to limit warming to 2 or 1.5°C above preindustrial level, although combined Intended Nationally Determined Contributions (INDCs) are likely insufficient to achieve these targets. We propose a set of idealized emission pathways consistent with the targets. If countries reduce emissions in line with their INDCs, the 2°C threshold could be avoided only if net zero greenhouse gas emissions (GHGEs) are achieved by 2085 and late century negative emissions are considerably in excess of those assumed in Representative Concentration Pathway (RCP) 2.6 (net −5 Gt CO2/yr, compared with −1.5 Gt CO2/yr in RCP2.6). More aggressive near-term reductions would allow 2°C to be avoided with less end-of-century carbon removal capacity. A 10% cut in GHGEs by 2030 (relative to 2015) could likely achieve 2°C with RCP2.6 level negative emissions. The 1.5°C target requires GHGEs to be reduced by almost a third by 2030 and net zero by 2050, while a 50 year overshoot of 1.5°C allows net zero GHGEs by 2060.
 
Capitalism in Crisis
What Went Wrong and What Comes Next
Capitalism in Crisis

Ever since the emergence of mass democracy after World War II, an inherent tension has existed between capitalism and democratic politics; capitalism allocates resources through markets, whereas democracy allocates power through votes. Economists, in particular, have been slow to accept that this tension exists. Instead, they have tended to view markets as a realm beyond the political sphere and to see politics as something that gets in the way of an otherwise self-adjusting system. Yet how democratic politics and capitalism fit together determines today’s world. Politics is not a mistake that gets in the way of markets.

The conflict between capitalism and democracy, and the compromises the two systems have struck with each other over time, has shaped our contemporary political and economic world. In the three decades that followed World War II, democracy set the rules, taming markets with the establishment of protective labor laws, restrictive financial regulations, and expanded welfare systems. But in the 1970s, a globalized, deregulated capitalism, unconstrained by national borders, began to push back. Today, capital markets and capitalists set the rules that democratic governments must follow.

But the dominance of capital has now provoked a backlash. As inequality has widened and real wages for the majority of people have stagnated—all while governments have bailed out wealthy institutions at the first sign of trouble—populations have become less willing to accept the so-called costs of adjustment as their lot. A “double movement,” in the words of the Hungarian historian Karl Polanyi, occurs in such moments as these, when those who feel most victimized by markets reclaim the powers of the state to protect them. The rise of Bernie Sanders and Donald Trump in the United States is a product of this reaction, as is the strengthening of populist parties in Europe.

Three recent books shed light on this continuing tension between the imperatives of the market and the desires of the people. Together, they offer a biography of capitalism: where it came from, what went wrong, and where it may be going in a world of stagnant living standards, widening inequality, and rising carbon emissions. And the picture they paint is a bleak one.

THE RISE OF CAPITALISM

Capitalism: A Short History, by the German historian Jürgen Kocka, is aptly named. In just 169 pages, it tells the story of capitalism from its origins in the ancient long-distance trade routes of Mesopotamia to the 2008 financial crisis. This is no mean feat. Yet such brevity requires some simplification, which comes at a cost.

For Kocka, capitalism is “an essential concept for understanding modernity.” More important, it is a set of institutions that enshrine property rights, promote the use of markets to allocate resources, and protect capital. And it is also an ethos, he claims, a set of principles and ideas. Defining capitalism so expansively allows Kocka to see its earliest forms developing among traders in Mesopotamia, in the eastern Mediterranean, and along Asia’s Silk Road, until, by the eleventh century, the beginnings of a merchant capitalist bourgeoisie had emerged on the Arabian Peninsula and in China.

Capitalism developed later in Europe, boosted by long-distance trade with Asia and the Arab world, between the twelfth and fifteenth centuries. Merchants formed cooperative institutions that led to greater risk sharing, which encouraged the accumulation of capital. This development, Kocka writes, led to “the formation of enterprises with legal personalities of their own,” rudimentary capital markets, and, finally, banks whose fortunes became intimately connected with the rise of modern states through the management of their debts.

This alliance between merchant capitalism and the emergent state helped usher in the age of colonialism. Merchants, entrepreneurs, and conquistadors, with increasingly powerful states backing them, propelled European expansion. Critical to this expansion was the triangular trade, in which European merchants brought finished goods to Africa, traded them for slaves, and then exchanged those slaves in the New World for sugar and cotton that went back to Europe. This process helped embed capitalism deeper in Europe than in the Middle East and China: the scale of investment that such ventures required led to the rise of what would become known as “joint-stock companies” and the beginnings of what economic historians call “finance capitalism”—stock exchanges opened in Antwerp in 1531 and Amsterdam in 1611.

Much of the profits that early European capitalists enjoyed came from these profoundly illiberal activities. As Kocka points out, “capitalism . . . contains little in the way of resistance against inhumane practices.” Yet in the long run, capitalism laid the groundwork for democracy, because the wealth it generated, and the possibilities that came with its new institutions, disrupted the guilds, helped cities expand, and allowed nineteenth-century industrialization to evolve into twentieth-century managerial capitalism.

BLAME THE BANKERS

In Kocka’s narrative, each stage of capitalism begets the next, in an almost natural progression. Capitalism simply marches onward, for the most part benevolently—at least once the reformers abolished slavery and colonialism. But beginning around 1980, he writes, something started to go wrong. Firms started to derive a larger share of their profits from the financial sector than they did from real investments, a process economists call “financialization.” This process, according to Kocka, “imparted a new quality to the system.”

Modern finance, in contrast to the earlier, “productive” forms of finance that Kocka admires, seems to mainly consist of unproductive “locust” hedge funds that “cannibalize” good firms, contributing nothing to production in the wider economy. Meanwhile, Kocka insists, since the 1980s, governments have failed to exercise self-restraint, and publics have lived beyond their means. Massive growth in public and private debt in the developed world has been the result, which represents “a lasting source of destabilization for capitalism.”

But this trenchant critique of modern finance sits oddly alongside the rest of the book. For Kocka, the system was doing just fine until the rot of modern finance set in. He insists that financialization represents a break in the evolution of capitalism. But he fails to explain where it came from, if it didn’t emerge directly from those earlier forms of capitalism.

After all, the modern finance that Kocka condemns is not so different from the earlier, “productive” finance that he lauds. The financiers that got Germany into trouble in 2007 through their exposure to U.S. subprime mortgages were not “locust” hedge funds but traditional German development banks. And one of the world’s largest derivatives traders at the time of the crisis was Deutsche Bank—hardly a new institution on the financial scene. In short, the idea that financialization may be not a perversion of capitalism but the next stage in its evolution seems to be a little too uncomfortable for Kocka to fully consider.

IN THE RED

The German sociologist Wolfgang Streeck also sees modern capitalism as flawed. Yet its current plight is not an aberration, he argues in Buying Time, but a direct consequence of the unraveling of the postwar marriage of capitalism and democracy.

Streeck’s account focuses on Michal Kalecki, a Polish economist who came to prominence in the interwar period. Kalecki published a remarkable article in 1943 that predicted the economic turmoil of the 1970s. Kalecki argued that if full employment ever became the norm, workers would be able to move freely from job to job. Not only would this undermine traditional authority relationships within firms; it would also push wages up regardless of productivity levels, since workers would have more leverage to demand higher wages.

In response, firms would have to raise prices, creating a spiral of inflation that would eat into profits and lower real wages, which would, in turn, promote greater labor unrest. Kalecki argued that to restore profits, capitalists would rebel against the system that promoted full employment. In its place, they would seek to create a regime in which market discipline, with a focus on price stability rather than full employment, would be the primary goal of policy. Welfare protections would be rolled back, and the discipline that unemployment provides would be restored.

Kalecki’s predictions proved astonishingly accurate. By the 1970s, as Kalecki had foreseen, inflation had risen dramatically, profits had fallen, and capital began its rebellion. Organizations as diverse as the Swedish Employers’ Confederation and the Business Roundtable in the United States pressured governments to reduce taxes, especially on high earners. But cutting taxes in the recessionary early 1980s meant that revenues fell, deficits widened, and real interest rates rose as those deficits became harder to finance. At the same time, conservative governments, especially in the United Kingdom and the United States, set out to weaken labor and shrink the role of the state as they dismantled the regulations that had reined in the excesses of finance since the 1940s.

The financial industry could now grow unchecked, and as it expanded, investors sought safe assets that were highly liquid and provided good returns: the debt of developed countries. This allowed governments to plug their deficits and spend more, all without raising taxes. But the shift to financing the state through debt came at a cost. Since World War II, taxes on labor and capital had provided the foundation of postwar state spending. Now, as governments began to rely more and more on debt, the tax-based states of the postwar era became the debt-based states of the contemporary neoliberal era.

This transformation has had profound political consequences. The increase in government debt has allowed transnational capitalists to override the preferences of domestic citizens everywhere: bond-market investors can now exercise an effective veto on policies they don’t like by demanding higher interest rates when they replace old debt with new debt. In the most extreme cases, investors can use courts to override the ability of states to default on their debts, as happened recently in Argentina, or they can shut down an entire country’s payment system if that country votes against the interests of creditors, as happened in Greece in 2015. The financial industry has become, Streeck writes, “the second constituency of the modern state,” one more powerful than the people.

This shift from taxes to debt initially bought time for capitalism: it restored profits, destroyed labor’s ability to demand wage increases, tamed inflation to the point of deflation (which increases the real value of debt), and even seemed to provide prosperity for all after the crisis of the 1970s. Mortgages and credit cards allowed private citizens to rack up deficits of their own—a process the sociologist Colin Crouch has described as “privatized Keynesianism.” But it was all an illusion. Credit sustained the appearance of prosperity for the lower classes. In reality, the rich captured most of the newly created wealth. In the United States, for example, the top one percent more than doubled their share of the national income over the last three decades, as wages for the bottom 60 percent stood still.

In 2008, the financial crisis shattered this illusion. Governments bailed out the banks and transferred the costs of doing so to public budgets. Public debt exploded as governments bailed out the rich, and austerity measures, intended to reduce this new debt, have only compounded the losses of the majority of citizens. Capital continues to dominate democracy, especially in the EU: in Greece and Italy in 2011, technocrats replaced democratically elected governments, and in 2015, the so-called troika—the European Central Bank, the European Commission, and the International Monetary Fund—bulldozed Greek democracy.

So where Kocka blames profligate governments and debt-laden citizens for the current crisis, Streeck instead sees them as the victims. It’s not lavish public spending, he shows, but rather falling tax revenues and financial bailouts that have created so much government debt and empowered capital. If states are spending extravagantly on voters, as Kocka and those who fetishize austerity maintain, there is precious little to show for it. “Had the rise in public debt been due to the rising power of mass democracy,” Streeck writes, “it would be impossible to explain how prosperity . . . could have been so radically redistributed from the bottom to the top of society.”

Streeck foresees a prolonged period of low growth and political turmoil ahead, in which states commanded by creditors, allied with transnational investors, struggle to get resisting debtor states into line: think of Germany and Greece. “The clock is ticking for democracy,” Streeck writes, but “it must remain an open question . . . whether the clock is also ticking for capitalism.”

“NEOLIBERALISM IS BROKEN”

For the British journalist Paul Mason, that question is closed: capitalism’s current condition is terminal. In Postcapitalism, Mason writes that capitalism is “a complex, adaptive system which has reached the limits of its capacity to adapt.” The roots of capitalism’s demise, Mason argues, lie in the 1980s (also when Kocka saw problems arise), when capitalism was taken over by neoliberalism: an ideology and a set of policies that recognize no limits to the commodification of the world. Unfortunately for capitalism, “neoliberalism is broken.” To explain why, Mason turns to the work of Nikolai Kondratieff, a brilliant Soviet economist whom Stalin had murdered in 1938.

According to Kondratieff, capitalism goes up and down in 50-year cycles. At the bottom of a cycle, old technologies and business models cease to function. In response, entrepreneurs, both public and private, roll out new technologies to open up untapped markets, and an upswing begins. This leads to a loosening of credit, which accelerates the upswing. These cycles bring to mind the concept of “creative destruction” popularized in the 1940s by the economist Joseph Schumpeter. But Mason downplays the importance of the entrepreneur, whom Schumpeter cast in a central role, and focuses instead on the effect of class-based politics on productivity.

Mason’s first cycle runs from 1790 to 1848. The upswing began when British entrepreneurs first harnessed steam power to run their factories, and it ended with the depression of the 1820s. The subsequent downswing produced the revolutions of 1848, when the emergent bourgeois classes of Europe burst onto the historical stage. Mason’s second cycle runs from 1848 to the mid-1890s. The spread of railways, the telegraph, and shipping drove growth until the depression of the 1870s. In the decades that followed, strong labor movements gained momentum all over the world, and capital, in response, became more concentrated. Electricity and mass production then powered a third upswing that crashed in the Great Depression and the massive capital destruction of World War II. After the war, a fourth cycle began with innovations in electronics and synthetics, improvements in the organization of production, and labor’s relative victory over capital in the institutions of the welfare state. That cycle’s upswing peaked in the mid-1970s, but this time, there was no major depression. The fourth cycle stalled.

THE END OF CAPITALISM

Mason’s argument about why a major depression has not arrived during the past 40 years, the Great Recession notwithstanding, is partly conventional and partly surprising. The conventional explanation has four components. First, after U.S. President Richard Nixon took the dollar off the gold standard in 1971, the United States moved to a paper standard, which eliminated the constraints on deficit financing that the gold standard entailed. Second, the financialization of the developed economies masked the reality of stagnant incomes by substituting credit for wage increases. Third, the emergence of global imbalances in finance and trade allowed the United States to keep consuming as Asian countries stepped in as producers. Finally, advances in information technology empowered capital and weakened labor, and helped spread neoliberal practices across the globe.

That is a fairly familiar analysis. The unconventional part of Mason’s answer harks back to Marx and Kalecki and stresses how neoliberalism managed to prevent profits from falling more effectively than any previous economic system. Mason borrows from Marx and Kalecki the idea that average profits in any market will fall due to both competition and the flood of capital into a new market, which reduce returns on investment. As a result, capitalists will always try to replace human labor with machines to protect their share of profits. During a downswing, as profits shrink, capitalists will do everything they can to boost their share of profits at the expense of labor: they will force employees to work intensively and will accelerate their attempts to replace workers with machines.

In the past, such attempts to restore profits simply by crushing labor failed. In each of the first three waves, one way or another, workers managed to resist. The best examples of such resistance were the postwar constraints on capitalism: strong unions, rigorous regulations, and generous welfare systems. When workers defy capitalists’ attempts to squeeze profits from them by building such institutions, firms have to adapt. Rather than fight labor over the fixed distribution of income, they are forced to invest in improving workers’ productivity, to the benefit of both parties: this was the post–World War II growth story.

But under neoliberalism, capitalists have managed to squeeze labor in an entirely new way. Globalization obliterated the power of workers to resist, because if they did, capital—and jobs—could easily flow elsewhere. This explains why the number of labor strikes has declined so steeply all over the world. As Mason writes, “The fourth long cycle was prolonged, distorted and ultimately broken by factors that have not occurred before in the history of capitalism: the defeat . . . of organized labour, the rise of information technology and the discovery that once an unchallenged superpower exists, it can create money out of nothing for a long time.”

Still, Mason believes that these factors have only delayed capitalism’s inevitable collapse. Where Marx thought that organized labor would rise up and overthrow the system, Mason bets that information technology will destroy it from within. Digital goods, such as music files and software, create a real problem for markets: they destroy the role of price in balancing supply and demand. People can copy digital goods freely forever: they have zero marginal cost and are nonrival in consumption. When one person downloads a music file or a piece of code from the Internet, for example, she makes it no harder for anyone else to do the same. So the only way that firms can maintain their profits is by enforcing monopoly property rights: consider Apple and Samsung suing each other for the right to profit from patents or the need for major pharmaceutical companies to keep drugs prohibitively expensive.

Mason is optimistic about what will replace the profit motive. He points to decentralized networks such as Wikipedia, the “biggest information product in the world . . . made by 27,000 volunteers, for free,” and the rise of the so-called sharing economy: nonmarket peer production systems, where work has value but cannot be priced in a traditional manner. The result is a “contradiction in modern capitalism . . . between the possibility of free, abundant socially produced goods, and a system of monopolies, banks and governments struggling to maintain control over power and information.” In such a world, the central battle will be between those who want to preserve property rights and those who wish to destroy them in the name of democracy. The stakes, Mason argues, could not be higher. Without the revolution he calls for, the world will be vulnerable to a much greater threat: catastrophic climate change.

WHAT COMES NEXT?

Mason’s chapter “The Rational Case for Panic” confronts what most economists and politicians tend to shy away from: the idea that capitalism in its current form is going to kill everyone. Of course, people have predicted an environmental apocalypse before. A group of experts called the Club of Rome famously published The Limits to Growth in the 1970s, forecasting economic and environmental crises—and those predictions have failed to come to pass. But this time may be different.

The science behind climate change is better this time around, and it’s conclusive. The world is in trouble. As Mason notes, in 2012, the International Energy Agency predicted that even if world leaders implemented all the announced emissions-reduction plans, carbon dioxide emissions would rise by another 20 percent by 2035. The world cannot burn 60 to 80 percent of remaining known carbon fuel stocks without causing catastrophic warming. But under capitalism, this is exactly what the world will do. Carbon taxes will do little to change this reality.

Add to this mix an aging developed world with huge pension liabilities and a climate-shocked developing world of young people who have nowhere to go, and it’s little wonder that the Organization for Economic Cooperation and Development has forecast stagnant growth for the global economy for the next 50 years and an almost 40 percent rise in inequality in the world’s rich countries. But despite this stark warning, Mason emphasizes an aspect of capitalism that both Kocka and Streeck underplay: its adaptive potential.

It is highly likely, for instance, that statistics such as GDP underestimate the impact of new information-based technologies. Hal Varian, Google’s chief economist, might be exaggerating when he claims that the free search engine is worth $150 billion to users in the United States every year, but there is no doubt that Google has transformed the economics of finding information. Google saves everyone time and money—but that doesn’t show up in GDP. Although capitalism may be reaching its adaptive limits, it has been more robust than most doomsayers realize.

Nonetheless, Mason thinks that climate change may be the one bullet that capitalism cannot dodge. Neoliberals often naively assert that capitalism will generate a miracle technology at just the right moment to stave off catastrophe. But Mason argues that previous Hail Mary passes, such as geoengineering and carbon capture, have failed to pay off. What gives him hope is that large-scale technological innovations may not be as important as micro-level changes in the structure of property rights themselves.

Whether or not such a restructuring will be enough to save the world remains unclear. But Mason is right to hold out hope. Capitalism, in its current form, has reached a dead end. If ever there were a time for pessimism of the intellect and optimism of the will, it is now.
 
McMillan M, Leeson A, Shepherd A, et al. A high-resolution record of Greenland mass balance. Geophysical Research Letters. A high-resolution record of Greenland mass balance - McMillan - 2016 - Geophysical Research Letters - Wiley Online Library

We map recent Greenland Ice Sheet elevation change at high spatial (5 km) and temporal (monthly) resolution using CryoSat-2 altimetry. After correcting for the impact of changing snowpack properties associated with unprecedented surface melting in 2012, we find good agreement (3 cm/yr bias) with airborne measurements. With the aid of regional climate and firn modeling, we compute high spatial and temporal resolution records of Greenland mass evolution, which correlate (R = 0.96) with monthly satellite gravimetry and reveal glacier dynamic imbalance. During 2011–2014, Greenland mass loss averaged 269 ± 51 Gt/yr. Atmospherically driven losses were widespread, with surface melt variability driving large fluctuations in the annual mass deficit. Terminus regions of five dynamically thinning glaciers, which constitute less than 1% of Greenland's area, contributed more than 12% of the net ice loss. This high-resolution record demonstrates that mass deficits extending over small spatial and temporal scales have made a relatively large contribution to recent ice sheet imbalance.
 
Kuwait sizzles in 129-degree heat, setting all-time eastern hemisphere record
Kuwait, Iraq sizzle in 129-degree heat, setting all-time eastern hemisphere record

While much of the continental United States is baking in high heat and humidity, there is at least one spot on Earth dealing with far more intense heat.

On Thursday, with a strong area of high pressure parked across the Middle East, high temperatures soared above 125 degrees Fahrenheit, or 51.6 degrees Celsius, in Iraq, Kuwait, Saudi Arabia and western Iran.

In the community of Mitribah, Kuwait, the high temperature rocketed to a record-setting 129.2 degrees Fahrenheit, or 54 degrees Celsius.

If the World Meteorological Organization verifies this record, it would become the hottest temperature recorded on Earth outside of Death Valley, California, which holds the title of the hottest temperature on record.

This would make the Kuwait reading the hottest temperature on record in the eastern hemisphere as well as the hottest on record in Asia.

High chance that current atmospheric greenhouse concentrations commit to warmings greater than 1.5 °C over land : Scientific Reports

The recent Paris UNFCCC climate meeting discussed the possibility of limiting global warming to 2 °C since pre-industrial times, or possibly even 1.5 °C, which would require major future emissions reductions. However, even if climate is stabilised at current atmospheric greenhouse gas (GHG) concentrations, those warming targets would almost certainly be surpassed in the context of mean temperature increases over land only. The reason for this is two-fold. First, current transient warming lags significantly below equilibrium or “committed” warming. Second, almost all climate models indicate warming rates over land are much higher than those for the oceans. We demonstrate this potential for high eventual temperatures over land, even for contemporary GHG levels, using a large set of climate models and for which climate sensitivities are known. Such additional land warming has implications for impacts on terrestrial ecosystems and human well-being. This suggests that even if massive and near-immediate emissions reductions occur such that atmospheric GHGs increase further by only small amounts, careful planning is needed by society to prepare for higher land temperatures in an eventual equilibrium climatic state.
 
The media largely relegate the greatest challenge facing humanity to footnotes as industry and politicians hurtle us towards systemic collapse of the planet.

The climate crisis is already here – but no one’s telling us

The climate crisis is already here – but no one’s telling us | George Monbiot

What is salient is not important. What is important is not salient. The media turns us away from the issues that will determine the course of our lives, and towards topics of brain-melting irrelevance.

This, on current trends, will be the hottest year ever measured. The previous record was set in 2015; the one before in 2014. Fifteen of the 16 warmest years have occurred in the 21st century. Each of the past 14 months has beaten the global monthly temperature record. But you can still hear people repeating the old claim, first proposed by fossil fuel lobbyists, that global warming stopped in 1998.

Arctic sea ice covered a smaller area last winter than in any winter since records began. In Siberia, an anthrax outbreak is raging through the human and reindeer populations because infected corpses locked in permafrost since the last epidemic in 1941 have thawed. India has been hammered by cycles of drought and flood, as withering heat parches the soil and torches glaciers in the Himalayas. Southern and eastern Africa have been pitched into humanitarian emergencies by drought. Wildfires storm across America; coral reefs around the world are bleaching and dying.
 
Waggoner PE, Ausubel JH. A framework for sustainability science: A renovated IPAT identity. Proceedings of the National Academy of Sciences 2002;99(12):7860-5. A framework for sustainability science: A renovated IPAT identity

Learning actors' leverage for change along the journey to sustainability requires quantifying the component forces of environmental impact and integrating them. Population, income, consumers' behavior, and producers' efficiency jointly force impact.

Here, we renovate the “IPAT Identity” to identify actors with the forces. Forcing impact I are P for population, A for income as gross domestic product (GDP) per capita, C for intensity of use as a good per GDP, and T for efficiency ratios as impact per good. In the “ImPACT Identity,” parents modify P, workers modify A, consumers modify C, and producers modify T.

Because annual percentage changes in component forces add to a change in national impact, actors' leverage is reflected transparently in consistent units of annual percentage changes that can be compared from force to force.

Examples from energy and food, farming and manufacturing, and steel and water show that declining C, called dematerialization, can temper the sustainability challenge of growth (P × A), and that innovation or efficient technology that lowers T can counter rising consumption (P × A × C).

Income elasticity can accommodate connections between income and other forces. From rates of change of forces, the identity can forecast impacts.

Alternatively, by identifying the necessary change in forces to cause a projected impact, ImPACT can assay the likelihood and practicability of environmental targets and timetables.

An annual 2–3% progress in consumption and technology over many decades and sectors provides a benchmark for sustainability.

America’s next president must declare war on climate change in the same way President Franklin Roosevelt fought the Axis powers during World War II, climate activist Bill McKibben said in an article published today in The New Republic.

McKibben argued that the next president should harness the nation’s industrial might in exactly the same way Roosevelt did in the months leading up to the attack on Pearl Harbor and in the years following the U.S. entrance into the war.

“It’s not that global warming is like a world war. It is a world war. And we are losing,” wrote McKibben, an author and activist who co-founded 350.org to fight the Keystone XL pipeline project.

“Defeating the Nazis required more than brave soldiers,” he wrote. “It required building big factories, and building them really, really fast.”

American scientists “have been engaged in a quiet but concerted effort to figure out how quickly existing technology can be deployed to defeat global warming,” McKibben wrote, calling it a “modest start ... for a mighty Manhattan Project.”

McKibben, who supported Vermont Sen. Bernie Sanders (I), says the next administration need look no further than the calculations made by a team at Stanford University led by Mark Jacobson that determined how each state could by powered 100 percent by the sun, wind and water by 2050. Getting there requires about 6,448 gigawatts of clean energy to replace fossil fuels—or the equivalent of 295 solar factories the size of Elon Musk’s SolarCity Gigafactory under construction in Buffalo, N.Y.

But it’s possible, McKibben wrote, if the United States takes on a warlike approach to curtailing greenhouse gas emissions and the resulting global warming.

“Without the same urgency and foresight displayed by FDR—without immediate executive action—we will lose this war,” McKibben wrote.

We’re under attack from climate change—and our only hope is to mobilize like we did in WWII.
We Need to Literally Declare War on Climate Change
 
Historical documents reveal Arctic sea ice is disappearing at record speed

‘Next year or the year after, the Arctic will be free of ice’

Peter Wadhams has spent his career in the Arctic, making more than 50 trips there, some in submarines under the polar ice. He is credited with being one of the first scientists to show that the thick icecap that once covered the Arctic ocean was beginning to thin and shrink. He was director of the Scott Polar Institute in Cambridge from 1987 to 1992 and professor of ocean physics at Cambridge since 2001. His book, A Farewell to Ice, tells the story of his unravelling of this alarming trend and describes what the consequences for our planet will be if Arctic ice continues to disappear at its current rate.
