Global warming has plunged the planet into a crisis and the fossil fuel industries are trying to hide the extent of the problem from the public, NASA's top climate scientist says.
"We've already reached the dangerous level of carbon dioxide in the atmosphere," according to James Hansen, 67, director of NASA's Goddard Institute for Space Studies in New York. "But there are ways to solve the problem" of heat-trapping greenhouse gases like carbon dioxide, which Hansen said has reached the "tipping point" of 385 parts per million.
Hansen calls for phasing out all coal-fired plants by 2030, taxing their emissions until then, and banning the building of new plants unless they are designed to trap and segregate the carbon dioxide they emit.
The major obstacle to saving the planet from its inhabitants is not technology, insisted Hansen, named one of the world's 100 most influential people in 2006 by Time magazine.
