Exactly 20 years after he first warned Congress about the dangers of Global Warming, Jim Hansen, the director of NASA’s Goddard Institute of Space Sciences, told Congress on Monday that the world long ago passed the “dangerous level” for greenhouse gases in the atmosphere and needs to get back to 1988 levels. He said Earth’s atmosphere can only stay this loaded with man-made carbon dioxide for a couple more decades without changes such as mass extinction, ecosystem collapse and dramatic sea level rises.
“We’re toast if we don’t get on a very different path,” Mr. Hansen, director of the Goddard Institute of Space Sciences who is sometimes called the godfather of global warming science, told The Associated Press. “This is the last chance.”
