Unforced Variations: Feb 2016

This month’s open thread. Just so you know, a lot of people have complained that these threads have devolved – particularly when the discussion has turned to differing visions of solutions – and have therefore become much less interesting. Some suggestions last month were for a side thread for that kind of stuff that wouldn’t […]

Blizzard Jonas and the slowdown of the Gulf Stream System

Blizzard Jonas on the US east coast has just shattered snowfall records. Both weather forecasters and climate experts have linked the high snowfall amounts to the exceptionally warm sea surface temperatures off the east coast. In this post I will examine a related question: why are sea surface temperatures so high there, as shown in […]

2015 Temperatures

To no-one’s great surprise, 2015 was clearly a record year in all the surface temperature analyses (GISTEMP, NOAA, HadCRUT4, Cowtan&Way, JMA + Berkeley Earth). There is a lot of discussion of this in the press, and on the relevant websites, so not much to add here. A few figures didn’t make it into the official […]

Marvel et al (2015) Part 2: Media responses

This is a second post related to the new paper. The first post dealing with its substantive content is here. What with #AGU15 going on, and a little bit of overlap in content with Shindell (2014), NASA wasn’t particularly keen to put out a press release for the paper, but we did get a ‘web […]

Marvel et al (2015) Part 1: Reconciling estimates of climate sensitivity

This post is related to the substantive results of the new Marvel et al (2015) study. There is a separate post on the media/blog response. The by Kate Marvel and others (including me) in Nature Climate Change looks at the different forcings and their climate responses over the historical period in more detail than any […]

Unforced variations: Jan 2016

Happy New Year, and happy new open thread. As per usual, nuclear energy is off-topic – it’s not that it’s uninteresting, but it ends up dominating conversation to the total exclusion of everything else and just becomes repetitive and dull. Recent excursions on this topic shows what happens when we relax the moderation, so back […]

Unforced Variations: Dec 2015

This is a belated open thread for this month, for anything non-COP21 and non-AGU related.

#AGU15

So this week it’s the biggest Earth Science meeting on the planet… There is a lot of great science that will be freely streamed via AGU On-Demand (registration required), and there’ll be a lot of commentary using the hashtag #AGU15. Many posters will be available online too. A few highlights have already been discussed by […]

#COP21

Apparently there is a climate conference of some sort going on. Happy to answer any science questions as they arise…

Hiatus or Bye-atus?

Guest commentary by Stephan Lewandowsky, James Risbey and Naomi Oreskes The idea that global warming has “stopped” has long been a contrarian talking point. This framing has found entry into the scientific literature and there are now numerous articles that address a presumed recent “pause” or “hiatus” in global warming. Moreover, the “hiatus” also featured […]

Reports of our demise…

… have of course been greatly exaggerated. But we are having some issues with our domain name. The back story is perhaps interesting to others, so here is quick summary of the situation. Update: The account details have been restored and the domains renewed. We should be back to normal in a couple of days. […]

And the winner is…

Remember the forecast of a temporary global cooling which made headlines around the world in 2008? We didn’t think it was reliable and offered a bet. The forecast period is now over: we were right, the forecast was not skilful. Back around 2007/8, two high-profile papers claimed to produce, for the first time, skilful predictions […]

So what is really happening in Antarctica?

The recent paper by Zwally et al. in the Journal of Glaciology has been widely reported as evidence that Antarctic is gaining mass, and hence lowering sea level. Is it? Expert Jonathan Bamber weighs in. Guest post by Jonathan Bamber, University of Bristol There have been quite few big media stories related to Antarctica recently, […]

Climate change is coming to a place near you

What are the local consequences of a continued global warming? And what kind of future climate can you expect for you children? Do we expect more extreme events, and will a global warming affect the statistics of storms? Another question is how the local changes matters for local communities and the ecosystem. It may be […]

Unforced variations: Oct 2015

This month’s open thread. Since most climate related discussion this month will be focussed on the COP21… What is (or should be) the role of climate science in the upcoming negotiations? Discuss.

Bjørn Lomborg, just a scientist with a different opinion?

Bjørn Lomborg is a well-known media personality who argues that there are more important priorities than reducing emissions to limit global warming. In a recent controversy centering on him, the Australian government (known for its contradictory position on climate change) offered the University of Western Australia (UWA) $4 million to make Lomborg professor – which […]

Let’s learn from mistakes

The publication ‘Learning from mistakes in climate research’ is the result of a long-winded story with a number of surprises. At least to me. I have decided to share this story with our readers, since it in some aspects is closely linked with RealClimate. The core of this story is the reproduction and assessment of […]
