Andy Russell's weather and climate blog.
There’s an interesting new paper in Nature (King et al.) this week that looks at how much the Antarctic continental ice contributes to sea level changes. It initially caught my eye as it uses data from the GRACE satellites, which are very cool! They are twin satellites that can detect tiny changes in the distance [...]... Read more »

A while ago I wrote a post about an analysis of the US climate monitoring network led by Anthony Watts, who has a very popular climate skeptic blog. The reason for that post was that Menne et al. 2010 had used some of Watts’ analysis to find that US surface temperature trends aren’t affected much by [...]... Read more »

I’ve written a couple of posts recently looking at the cold UK weather in context and how snow forms. What I haven’t done, though, is looked at why it’s been so cold over Europe this winter (as well as last year’s winter). It just so happens that a paper came out in the Journal of [...]...

This is a post that aims to go through the evolution of the “Hockey Stick” from 1990 to the present day. It naturally misses out parts of the story, which deserve far more analysis, simply to keep the post short. Comments that expand on the bits I’ve omitted are welcome! What is the “Hockey Stick” [...]... Read more »

I realise that the volcano that is currently erupting in Iceland has caused a lot of problems for a lot of people. However, if I can see one plus side it’s all the impromptu atmospheric science that is going on around it. For example, the first paper about the volcano, which is looking at the [...]... Read more »

Most of our analyses of climate change have focused on the atmosphere and mostly over land and, therefore, mostly in the Northern Hemisphere. This is simply because that is where our best data comes from. This is starting to change though. A paper published in Nature this week uses relatively new ocean data to show [...]... Read more »
I’ve been pretty distracted recently with the Institute of Physics issue. I’ll hopefully draw that chapter to a close in the next couple of weeks (it looks like the IoP are going to stick their head in the sand and wait for it to blow over) but right now I’m bringing my current project [...]...

There’s clearly some interest in the IoP evidence submission and my original letter to the IoP didn’t really go into my objections in great detail. I thought I should go through the evidence submission in one place instead of explaining my views in response to blog comments.
Overall, I’m not objecting to the statement because [...]... Read more »

Antarctica has been in the news recently because two large icebergs (one about 60 miles long and the other about 50) have broken off the continent. These “calving” events often occur naturally and these ones are probably not linked to climate change, although they might affect the global ocean circulation.
But I thought that this [...]... Read more »

[This post is based a question I got in response to a previous post but thought it deserved a short post on its own as there's a few interesting points.]
There’s been a lot of bad press recently for climate science but a lot of has focused on very minor issues. For example, most of [...]... Read more »
Whilst I would describe myself as a scientific skeptic, in that I will try to investigate claims before coming to a judgement, I would not say I was a “climate change skeptic”. This term is often used to label those that are irrationally dismissive of the scientific evidence (or worse). Several commentators on [...]... Read more »
