The relentless, weather-gone-crazy type of heat that has blistered theUnited 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 scientistJames Hansen. He says that statistically what’s happening is not random or normal, but pure and simple climate change.
“This is not some scientific theory. We are now experiencing scientific fact,” Hansen told The Associated Press in an interview.
Hansen is a scientist at NASA’s Goddard Institute for Space Studies in New York and a professor at Columbia University. But 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.
However, several climate scientists praised the new work.
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:
—Last year’s devastating Texas-Oklahoma drought.
—The 2010 heat waves in Russia and the Middle East, which led to thousands of deaths.
—The 2003 European heat wave blamed for tens of thousands of deaths, especially among the elderly in France.
The analysis was written before the current drought and record-breaking temperatures that have seared much of the United States this year. But Hansen believes this too is another prime example of global warming at its worst.
