were this high came during the Pliocene Epoch, which extended from about 5.3 million to 2.6 million years ago. During that period, average sea levels were about 50 feet higher than they are today and forests grew as far north as the Arctic, said Rob Jackson, a professor of earth system science at Stanford University. “Earth was a very different place,” he said. “You would hardly recognize the land surface, and my gosh, we don’t want to go there.
, named for Keeling’s father, Charles David Keeling, who began taking daily measurements of atmospheric carbon dioxide in 1958 from atop the Mauna Loa Observatory in Hawaii. The curve shows a steep climb, owing to human-caused climate change. But it’s hard to say exactly what these changes will bring, or when. Some things, like the loss of vegetation and sea-ice coverage, will grow increasingly visible in the short term. Other things, like theand Greenland, occur more slowly. “But these impacts are going to persist for a very long time,” said Dana Royer, a professor of earth and environmental sciences at Wesleyan University in Middletown, Connecticut. “Once that happens, we can’t really reverse it.
