THE NEWS IN mid-May was grim: Scientists announced that melt across the West Antarctic was proceeding much faster than before. In fact, they said that at this point the melt of the six great glaciers fronting Amundsen Bay was “unstoppable,” and that over a number of decades it would raise sea levels by 10 feet or more.
This is another way of saying: Given dominion over the earth, we’ve failed. We’ve taken one after another of the planet’s great physical features and wrecked them. The Arctic? Summer sea ice is reduced by 80 percent, and it’s an every-year affair now to boat through the Northwest Passage, impassably choked by ice until this millennium began. The seven seas? Thirty percent more acidic than they were in the past—and the acidity could double or triple by the end of the century. The Antarctic? It’s not just warming rapidly, but its wind patterns have been changed by the ozone hole in ways that amplify the heating. Storms are stormier, droughts are deeper, fires last longer, rain falls harder.
And all because it was a little easier and a little cheaper not to change off fossil fuels. When scientists sounded the alarm about all this in the late 1980s, the atmospheric concentration of carbon dioxide was about 350 parts per million—or what we now consider the upper bound of safety. If we’d heeded their fervent warnings, we’d have moved with great speed to convert to solar and wind power. We’d have parked our SUVs. We’d have insulated every home in the world. It would have cost money and it would have been inconvenient; on the other hand, it could have bred solidarity in much the same way that preparing for World War II transformed the U.S.
