Could we run a twitter poster session?
I’ve been enjoying following the mega-meetup-12k-scientist-strong EGU conference via the hashtag #EGU15. In particular, people are tweeting pictures of and links to their posters, as adverts for other scientists that happen to be on twitter. This got me to thinking: could we use twitter to run an online-only poster session? I really like poster sessions […]
Internal variability in surface temperature and the hiatus
Our paper Quantifying the likelihood of a continued hiatus in global warming is published today in Nature Climate Change. Here is the New Scientist take, the Carbon Brief take, and the Met Office Research News article. Chris Roberts took on a huge task, processing massive amounts of data in the CMIP5 climate model archive, and leading […]
Why model climate?
I wrote a talk on climate modelling, aimed at the interested-but-non-specialist public. Here it is. http://vimeo.com/103371375 It touches on: 1) The choices we have to make as a society. 2) The difficulty of doing controlled experiments with a single Earth. 3) The idea of a climate model. 4) A really simple climate model from first […]
A brief comment on timing
In a comment on Mora et al. (2013), we highlight some errors the authors make in calculating and expressing the uncertainty in the timing of “climate departure” – the time at which a particular place on Earth will see a climate unprecedented in the historical record. There is a reply by the authors of the […]
The great thing about UQ is we know how to spell it
It’s been pretty busy round these parts, here are a few notes from the last month or so. Natural variability – Energy budget Our paper on natural variability in the Earth’s energy budget got a nice write-up from John Abraham in the Guardian. Mat Collins happened to be passing, and took a nice picture of […]
A brief observation on statistical significance
This has been on my mind for a while. I think the observation is best summed up as: If somebody asks if something is statistically significant, they probably don’t know what it means. I don’t mean to offend anyone, and I can think of plenty of counter examples*, but this is borne out of long […]
Why I don’t advocate for climate science policy
I was going to write a long essay on why I try to avoid advocating for any one particular policy for climate, but I think this probably makes the point fairly well. One of the funny things about the hoo-ha around Tamsin’s piece was that the reaction rather confirmed the point*. People hate hate HATE […]
How fast is Arctic sea ice refreezing this year?
Bishop Hill have a post stating “Isn’t the Arctic refreeze quick this year?” I’ve done a quick check on the rate that the ice is refreezing this winter, compared to the previous years. It’s not a terribly scientific method – just copying this years trajectory and moving it to match the previous years by eye. […]
Constraining climate models with observations
This post is an introduction to our new paper, The potential of an observational data set for calibration of a computationally expensive computer model, for non specialists. The paper is in open review, and so can be commented on by anybody. We would appreciate feedback, so please consider making a comment at the open review […]
