Vulnerability and resilience

I’m starting to better understand why some reasonable people are often concerned about the way in which the impact of extreme weather events are sometimes framed. It’s quite well explained in this recent paper by Myanna Lahsen and Jesse Ribot … Continue reading

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
