"Early naturalists talked often about "deep time"--the perception they had, contemplating the grandeur of this valley or that rock basin, of the profound slowness of nature. But the perspective changes when history accelerates. What lies in store for us is more like what aboriginal Australians, talking with Victorian anthropologists, called "dreamtime," or "everywhen": the semi-mythical experience of encountering, in the present moment, an out-of-time past, when ancestors, heroes, and demigods crowded an epic stage. You can find it already by watching footage of an iceberg collapsing into the sea--a feeling of history happening all at once. It is. The summer of 2017, in the Northern Hemisphere, brought unprecedented extreme weather: three major hurricanes arising in quick succession in the Atlantic; the epic "500,000-year" rainfall of Hurricane Harvey, dropping on Houston a million gallons of water for nearly every single person in the entire state of Texas; the wildfires of California, nine thousand of them burning through more than a million acres, and those in icy Greenland, ten times bigger than those in 2014; the floods of South Asia, clearing 45 million from their homes. Then the record-breaking summer of 2018 made 2017 seem positively idyllic. It brought an unheard-of global heat wave, with temperatures hitting 108 in Los Angeles, 122 in Pakistan, and 124 in Algeria. In the world's oceans, six hurricanes and tropical storms appeared on the radars at once, including one, Typhoon Mangkhut, that hit the Philippines and then Hong Kong, killing nearly a hundred and wreaking a billion dollars in damages, and another, Hurricane Florence, which more than doubled the average annual rainfall in North Carolina, killing more than fifty and inflicting $17 billion worth of damage. There were wildfires in Sweden, all the way in the Arctic Circle, and across so much of the American West that half the continent was fighting through smoke, those fires ultimately burning close to 1.5 million acres. Parts of Yosemite National Park were closed, as were parts of Glacier National Park in Montana, where temperatures also topped 100. In 1850, the area had 150 glaciers; today, all but 26 are melted." --
