Gone was the entire United States east of the Mississippi River, together with North Dakota, Minnesota, Missouri, Arkansas, Louisiana, and Iowa. A murmur rolled through the hall—even scientists enjoy a good animated graphic over tables of numbers any day. After Serreze’s talk we milled around some more, wrangling over things like “model downscaling,” “cloud forcing,” and “nonlinear dynamics.” Some were revising the old projections for an ice-free Arctic Ocean from 2050 to 2035, or even 2013. Others—including me—argued for natural variability. We thought the 2007 retreat could just be a freak and the sea ice would recover, filling up its old territory by the following year. We were wrong. The excursion persisted for two more years, with 2008 and 2009 also breaking records for the Arctic summer sea-ice minimum. They were the second- and third-lowest years ever seen, and had followed right on the heels of what happened before.290 Ice Reflects, Oceans Absorb The broader impacts of amplified warming—more rain and snow, and reduced summer sea ice at the top of our planet—extend far beyond the region itself.

By responding in this way to small global temperature changes, sea ice thus amplifies them even more.292 While its global effect is small, the ice-albedo feedback is uniquely powerful in the Arctic because it is the only place on Earth where a major ocean gets coated with ephemeral floating sea ice during the summer. Antarctica, in contrast, is a continent of land, thickly buried beneath permanent, kilometers-thick glaciers. For this and several other reasons, climate warming is more amplified in the Arctic than the Antarctic. 293,294 As an ice-free Arctic Ocean warms up, it acts like a giant hot-water bottle, warming the chilly Arctic air as the Sun crawls off the horizon each winter. The sea ice that does eventually form is thin and crackly, allowing more of the ocean’s heat to seep out even during the depths of winter. Winters become milder, the autumn freeze-up happens later, and the spring thaw arrives earlier. The warming effect is highest over the ocean and from there spills southward, warming vast landscapes across some of the coldest terrain on Earth.

For a brief time window each year, it would become feasible to cross right over the North Pole in ice-strengthened ships. A dream come true. Dream On So by 2050 will global trade flows be pouring through the Arctic Ocean, as they do today through the Suez and Panama canals? Impossible. Those operate 365 days per year with no ice whatsoever. At best the Arctic Ocean will become ice-free for a few days to a few weeks in summer and even then, there is no such thing as a truly “ice-free” Arctic Ocean. From autumn through spring, there will be expanding first-year ice cover, slowing ships down even with icebreaker escort. In summer, there will always be lingering bits of sea ice floating around, as well as thick icebergs calved from land-based glaciers into the sea (a glacier iceberg sank the Titanic, not sea ice). The Arctic Ocean will always freeze in winter—or at least we’d better hope so.

Given that these high-altitude wind belts-narrow corridors of rapidly moving air at the top of the troposphere-mark the boundaries between the different air masses, their gradual movement shows that the location of the world's typical climate zones is already starting to shift in response to rising global temperatures. What we have so far witnessed is still only the beginning. As one group of scientists warned recently: ‘The Arctic system is moving toward a new state that falls outside the envelope of recent Earth history.’ As future chapters show, this new ice-free Arctic will see extreme levels of warmth unlike anything experienced by the northern polar regions for millions of years. Danger in the Alps When the Englishmen Craig Higgins and Victor Saunders left the Hornli hut at 4 a.m. on 15 July 2003, they had no idea that they would end the day being part of the biggest-ever rescue on Switzerland's iconic Matterhorn. The ascent began straightforwardly, with the two climbers scaling three rock towers, after which steep slabs led up to a small bivouac hut midway up the Hornli ridge.

It is time to prepare, both emotionally and practically, for a disaster. I am a social scientist, not a climatologist. So who am I to spread panic and fear when the world’s top scientists say we have twelve years? Like many readers, I had assumed the authority on climate was the IPCC – the Intergovernmental Panel on Climate Change – but it turns out they’ve been consistently underestimating the changes. In 2007 they said an ice-free Arctic was a possibility by 2100. That sounds far enough away to calm the nerves. But real-time measurements are documenting such rapid loss of ice that some of the world’s top climate scientists are saying it could be ice free in the next few years. Sea-level rise is a good indicator of the rate of change, because it is affected by many factors. In 2007, satellite data showed a sea-level rise of 3.3 millimetres per year.

The scope of Changing Climate was impressive, with its various commissions on agriculture and social policy, its subchapters with titles both specific and grand: “The Colorado River” and “Weeds,” “The Deep Circulation” and “The Time Dimension.” Nevertheless, as Pomerance flipped through its pages, he could see that it offered no significant new findings. “We are deeply concerned about environmental changes of this magnitude,” read the executive summary. “We may get into trouble in ways that we have barely imagined.” The authors did try to imagine some of them: an ice-free Arctic, for instance, and Boston sinking into its harbor, with Beacon Hill surfacing as an island two miles off the coast. There was speculation about political revolution, trade wars, and a long quotation from A Distant Mirror, the medieval history written by Barbara Tuchman, Pomerance’s aunt, describing how climatic changes in the fourteenth century led to “people eating their own children” and “feeding on hanged bodies taken down from the gibbet.”

To avoid bringing something comparably drastic upon ourselves, the ecological economists propose we rethink the way we provision civilization—starting now. It’s a big job. Today’s globalized economy literally means an economy the size of our planet—but as Daly points out, that also means there’s no more room to expand. The addition of more fuel reserves than we once thought we had—in the form of gas we free by shattering bedrock, oil we wring from sand and shale, and newly ice-free Arctic deposits—seems impressive from a short-term perspective, such as an election cycle. But the math reveals that they’ll buy us relatively little extra time, and may cost much more than they give. The techniques to harvest them make alarming messes, and burning them turns the skies even more uncontrollable and the oceans increasingly corrosive. “The closer the economy approaches the scale of the Earth,” Daly told the UK’s Sustainable Development Commission in 2008, “the more it will have to conform to the physical behavior of the Earth.”

But if we wait to act until all the numbers are in, we’ll have waited too long, which is why scientists keep jamming every possible variable into models that predict our likely future. Because technically they’re speculative, their credibility is attacked by whoever profits from business as usual. But thus far, the main failing in climate change models has been timidity: the worst possible case for an ice-free Arctic summer, predicted for 2050 back in 2008, has now been moved to as early as 2016. At what point, and with what proof or words, might politicians and industry be convinced that drastic change is already upon us, and will only worsen—perhaps fatally—if we don’t respond accordingly? Later that year, I would be asked by a prominent Japanese business magazine if I thought that people were being hysterical to demand an end to nuclear power in the wake of the Fukushima tragedy.

In 2010, Russia issued only four permits for Arctic sea passage; in 2013, it issued four hundred. That year, the nineteen-thousand-ton Yong Sheng sailed from Dalian to Rotterdam in thirty-five days. At present, more than fifty times more cargo traverses the Suez each year than the Arctic, but because temperatures rise faster at the earth’s poles (while water levels rise faster at the equator), the Arctic could become a major reliable shipping route by 2020. Ice-free Arctic shipping features two major corridors: The Northern Sea Route, taken by China’s Yong Sheng, connects the two ends of Eurasia (the Far East and northern Europe) over Russia, through the Bering Strait and past Russia’s Kamchatka Peninsula—a full two weeks faster than the Suez Canal route. Meanwhile, the Northwest Passage connects East Asia to North America’s East Coast by passing over Alaska and Canada instead of Russia, shaving ten thousand kilometers off the Panama Canal route.
