The relentless, weather-gone-crazy type of heat that has blistered the United States and other parts of the world in recent years is so rare that it can’t be anything but man-made global warming, says a new statistical analysis from a top government scientist.
The research by a man often called the “godfather of global warming” says that the likelihood of such temperatures occurring from the 1950s through the 1980s was rarer than 1 in 300. Now, the odds are closer to 1 in 10, according to the study by NASA scientist James Hansen. He says that statistically what’s happening is not random or normal, but pure and simple climate change.
In a blunt departure from most climate research, Hansen’s study — based on statistics, not the more typical climate modeling — blames these three heat waves purely on global warming:
