Extreme weather event attribution
This is a joint post between myself and Eric Winsberg, Professor of Philosophy at the University of South Florida. Eric has just published, together with Naomi Oreskes and Elisabeth Lloyd, a paper called Severe Weather Event Attribution: Why values won’t … Continue reading
Early 20th century warming
I’ve noticed that Judith Curry is discussing the early twentieth century warming. The idea is that there was a period of warming during the early twentieth century that was similar to the warming we’ve experienced since the second half of … Continue reading
Disasters and Climate Change – part 2
Since I have a bit of free time, I thought I would expand a little on my Review of Roger Pielke Jr’s book about Disasters and Climate Change. As I mentioned in my earlier post, there were a number of … Continue reading

The attribution question
It seems as though the issue of trying to attribute an anthropogenic influence to an extreme weather event is controversial on a number of levels. It sometimes seems to divide even those who largely agree, and almost always produces a … Continue reading

“very likely” versus “extremely likely”
In IPCC land “very likely” means 90% – 100% probability, while extremely likely means 95% – 100% probability. In light of that, I was wondering if anyone had any insights as to why, in Chapter 10 of the IPCC’s WGI … Continue reading

Climate change by numbers
I watched the much-hyped BBC4 show climate change by numbers and thought it was pretty good. It covered 3 basic numbers; why we think global surface temperatures have risen by 0.85oC since 1880, why we’re 95% (or more) sure that … Continue reading
“More than half” is the same as “> 50%”!
A while ago Judith Curry wrote a rather confusing post about the IPCC’s attribution statement (that more than 50% of the warming since 1950 was anthropogenic). Gavin Schmidt responded on RealClimate, and Judith Curry has been promising to respond to … Continue reading
