James Hansen is one of the most well-known, and well-respected, climate scientists the species has. Now he’s ‘fessed up to the error of his ways. When he made his bold claims about climate impacts in 1988, he underestimated what was coming. Here’s the first few paragraphs of his opinion piece at the Washington Post website. On Monday some new scientific paper by him and other boffins is going to tell us how we’re more screwed more quickly than we previously thought. That’ll be fun!

When I testified before the Senate in the hot summer of 1988 , I warned of the kind of future that climate change would bring to us and our planet. I painted a grim picture of the consequences of steadily increasing temperatures, driven by mankind’s use of fossil fuels.
But I have a confession to make: I was too optimistic.
My projections about increasing global temperature have been proved true. But I failed to fully explore how quickly that average rise would drive an increase in extreme weather.
In a new analysis of the past six decades of global temperatures, which will be published Monday, my colleagues and I have revealed a stunning increase in the frequency of extremely hot summers, with deeply troubling ramifications for not only our future but also for our present.
This is not a climate model or a prediction but actual observations of weather events and temperatures that have happened. Our analysis shows that it is no longer enough to say that global warming will increase the likelihood of extreme weather and to repeat the caveat that no individual weather event can be directly linked to climate change. To the contrary, our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change….
And here is a link to the rest of it.
