No models, just statistical analysis of what has been happening to our Earth's temperature and weather.
Hansen's conclusion? The past 10 years of extreme weather events is significant evidence of global warming, as opposed to a continuing random series of weather extremes. Per Hansen, humans and their greenhouse gas emissions are causing the global warming and the associated weather extremes.
My opinion? I see many sound reasons to agree with Hansen, and no significant reasons to disagree. But will this report by Hansen make any difference regarding our actions?
From an article in the Washington Post,
“The science in Hansen’s study is excellent “and reframes the question,” said Andrew Weaver, a climate scientist at the University of Victoria in British Columbia who was a member of the Nobel Prize-winning international panel of climate scientists that issued a series of reports on global warming.
Rather than say, ‘Is this because of climate change?’ That’s the wrong question. What you can say is, ‘How likely is this to have occurred with the absence of global warming?’ It’s so extraordinarily unlikely that it has to be due to global warming,” Weaver said." (bold by finbliz)
And now another quote from the same article, so true and so depressing:
"Science policy expert Roger Pielke Jr. of the University of Colorado said Hansen clearly doesn’t understand social science, thinking a study like his could spur action. Just because something ought to happen, doesn’t mean it will, he said."
