How confident should you have been about confidence intervals?

OK, it’s answer time for these questions. First, a little background. This is the paper, or rather, here it is to download. The questions were asked of over 100 psychology researchers and 400 students and virtually none of them got all the answers right, with more wrong than right answers overall. The questions were modelled…

How confident are you about confidence intervals?

Found a fun little quiz somewhere, which I thought some of my readers might like to take. My aim is not to embarrass people who may get some answers wrong – in testing, the vast majority of all respondents (including researchers who reported substantial  experience) were found to make mistakes. My hypothesis is that my readers…

Costs of delaying action on climate change

This post was prompted by a silly twitter argument, about which probably the least said the better. Someone who has set themselves up as some sort of “climate communicator” had asserted that if we don’t halve our emissions in 12 years then the world as we know it will end. Moreover, anyone who even thought…

Comments on Cox et al

I previously blogged quite a lot about the Cox et al paper (see here, here, here). It generated a lot of interest  in the scientific community and I’m not terribly surprised that…

That new ocean heat content estimate

From Resplandy et al (conveniently already up on sci-hub): Our result — which relies on high-precision O2 measurements dating back to 1991 — suggests that ocean warming is at the high end of previous estimates, with implications for policy- relevant measurements of the Earth response to climate change, such as climate sensitivity to greenhouse gases…

Cloudy with a chance of meatballs (on the pizza)

The CFMIP workshop provided the excuse we were looking for in order to visit Boulder again. Last year this meeting had been held in Tokyo which, on top of being a long way away, also directly clashed with the PMIP workshop that jules was duty-bound to attend. The main focus of the CFMIP workshop is…

EGU 2018 Day 1

Going to try a mini-blog straight away to avoid a big backlog. Arriving late on Sunday to a self-catering apartment meant a quick shop on Monday morning and missed session. As I said to Didier when he complained that I missed his 8:30 session (with a sceptic talk first up), I had something else more…
