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:

—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.

In a landmark 1988 study, Hansen predicted that if greenhouse gas emissions continue, which they have, Washington, D.C., would have about nine days each year of 95 degrees or warmer in the decade of the 2010s. So far this year, with about four more weeks of summer, the city has had 23 days with 95 degrees or hotter temperatures.

Hansen says now he underestimated how bad things would get.
