The relentless, weather-gone-crazy type of heat that has blistered the United States, Canada and other parts of the world in recent years is so rare it can't be anything but man-made global warming, according to a new statistical analysis from a top American scientist.
The research by a man often called the "godfather of global warming" says that, from the 1950s through the 1980s, the likelihood of such sweltering temperatures occurring was rarer than 1 in 300. Now, the odds are closer to 1 in 10, according to the study by James Hansen. The NASA scientist says that statistically, what's happening is not random or normal, but pure and simple climate change.
"This is not some scientific theory," Hansen told The Associated Press in an interview. "We are now experiencing scientific fact."
Hansen is a scientist at NASA's Goddard Institute for Space Studies in New York and a professor at Columbia University. He is also a strident activist who has called for government action to curb greenhouse gases for years. While his study was published online Saturday in the Proceedings of the National Academy of Science, it is unlikely to sway opinion among the remaining climate change skeptics.
