Predicting annual temperatures a year ahead

Filed under: — gavin @ 16 September 2016

I have a post at Nate Silver’s 538 site on how we can predict annual surface temperature anomalies based on El Niño and persistence – including a (by now unsurprising) prediction for a new record in 2016 and a slightly cooler, but still very warm, 2017.

An update on mid-latitude cyclones and climate change

Filed under: — rasmus @ 6 September 2016

Why is it so hard to say what the future North European climate will look like? A recent review paper by Shaw et al, 2016 explains the reason in persuasive terms.

Unforced variations: Sep 2016

Filed under: — group @ 1 September 2016

To come this month: Arctic sea ice minimum, decisions from the IPCC scoping meeting on a report focused on the 1.5ºC target, interesting paleo-climate science at #ICP12 and a chance to stop arguing about politics perhaps.

Usual rules apply.

Australian silliness and July temperature records

Filed under: — gavin @ 16 August 2016

Some of you that follow my twitter account will have already seen this, but there was a particularly amusing episode of Q&A on Australian TV that pitted Prof. Brian Cox against a newly-elected politician who is known for his somewhat fringe climate ‘contrarian’ views. The resulting exchanges were fun:

Unforced variations: Aug 2016

Sorry for the low rate of posts this summer. Lots of offline life going on. ;-)

Meantime, this paper by Hourdin et al on climate model tuning is very interesting and harks back to the FAQ we did on climate models a few years ago (Part I, Part II). Maybe it’s worth doing an update?

Some of you might also have seen some of the discussion of record temperatures in the first half of 2016. The model-observation comparison including the estimates for 2016 are below:




It seems like the hiatus hiatus will continue…
