Global warming: "we have a very brief window of opportunity"

On Wednesday at the Climate Change Research Conference in Sacramento, California, James Hansen the director of NASA's Goddard Institute for Space Studies made a firm statement regarding global climate change. He said the world has a 10-year window of opportunity to keep carbon dioxide emissions growth in check to limit the increase in global temperatures to 1 degree Celsius (1.8 degrees Fahrenheit). He warned that taking no action would result in drastic consequences including a significant rise in sea levels putting most of Manhattan under water; an increase in the frequency and duration of droughts and heat waves; a rise in the number and intensity of hurricanes; and the extinction of about half of the world's species.
