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 […]

Ice-core dating corroborates tree ring chronologies

Guest commentary from Jonny McAneney You heard it here first… Back in February, we wrote a post suggesting that Greenland ice cores may have been incorrectly dated in prior to AD 1000. This was based on research by which compared the spacing between frost ring events (physical scarring of living growth rings by prolonged sub-zero […]

Unforced variations: Aug 2015

This month’s open thread. A traditional time to discuss the Arctic sea ice minimum. But NH summer heatwaves, and to be fair, snow in the southern hemisphere, are also fair game…

Unforced variations: July 2015

This month’s open thread. How about a focus on cimate science this time? Data visualizations anyone?

Heaven belongs to us all – the new papal encyclical

Guest post by Brigitte Knopf With his encyclical “Laudato Si” the Pope has written more than a moral appeal without obligation. He has presented a pioneering political analysis with great explosive power, which will probably determine the public debate on climate change, poverty and inequality for years to come. Thus, the encyclical is also highly […]

Debate in the noise

Last week there was an international media debate on climate data which appeared to be rather surreal to me. It was claimed that the global temperature data had so far shown a “hiatus” of global warming from 1998-2012, which was now suddenly gone after a data correction. So what happened? One of the data centers […]

NOAA temperature record updates and the ‘hiatus’

In a new paper in Science Express, describe the impacts of two significant updates to the NOAA NCEI (née NCDC) global temperature series. The two updates are: 1) the adoption of for the ocean temperatures (incorporating a number of corrections for biases for different methods), and 2) the use of the larger International Surface Temperature […]

Unforced Variations: June 2015

This month’s open thread. Some interesting trends in ocean heat content, surface temperatures, multiple oddly reported papers (which are often linked to ambiguous press releases…) etc. But at least we aren’t working in political science…
