Yamal and Polar Urals: a research update
Guest commentary from Tim Osborn, Tom Melvin and Keith Briffa, Climatic Research Unit, UEA Records of tree-ring characteristics such as their width (TRW) and density (usually the maximum density of the wood formed towards the end of the growing season – the “maximum latewood density” – MXD) are widely used to infer past variations in [...]

Introducing PubPeer.com
Guest post from PubPeer.com The process of reviewing published science is constantly occurring and is now commonly being called post-publication peer review. It occurs in many places including on blogs such as this one, review articles, at conferences around the world, and has even been encouraged on the websites of some journals. However, the process [...]
The scientific debate on climate change

This month’s open thread.
The answer is blowing in the wind: The warming went into the deep end
There has been an unusual surge of interest in the climate sensitivity based on the last decade’s worth of temperature measurements, and a lengthy story in the Economist tries to argue that the climate sensitivity may be lower than previously estimated. I think its conclusion is somewhat misguided because it missed some important pieces of [...]
The PAGES-2k synthesis
Guest commentary by Darrell Kaufman (N. Arizona U.) In a major step forward in proxy data synthesis, the PAst Global Changes (PAGES) 2k Consortium has just a suite of continental scale reconstructions of temperature for the past two millennia in Nature Geoscience. More information about the study and its implications are available at the FAQ [...]
Ice hockey
Eric Steig It is well known that ice shelves on the Antarctic Peninsula have collapsed on several occasions in the last couple of decades, that ice shelves in West Antarctica are thinning rapidly, and that the large outlet glaciers that drain the West Antarctic ice sheet (WAIS) are accelerating. The rapid drainage of the WAIS [...]
Verification of regional model trends
Guest post by Geert Jan van Oldenborgh, Francisco Doblas-Reyes, Sybren Drijfhout and Ed Hawkins Climate information for the future is usually presented in the form of scenarios: plausible and consistent descriptions of future climate without probability information. This suffices for many purposes, but for the near term, say up to 2050, scenarios of emissions of [...]
Thin Ice — the movie
Some of my friends have made a film, Thin Ice, which tells the story of CO2 and climate from the standpoint of the climate scientists who are out there in the trenches trying to figure out what is going on. I have a small role in the film myself, and I am sure RealClimate readers [...]
Should regional climate models take the blame?
recently provided a critical review of regional climate models (“RCMs”). I think his views has caused a stir in the regional climate model community. So what’s the fuzz all about? RCMs provide important input to many climate services, for which there is a great deal of vested interest on all levels. On the international stage, [...]
Movie review: SWITCH
This year, the Geological Society of America is rolling out their SWITCH Energy Awareness campaign. The centerpiece of the campaign is a documentary film, SWITCH, which purports to be about the need for a transformation in the world’s energy systems. Recently, I attended the Chicago premier of the film, presented as part of the [...]

Open thread for April…
Response by Marcott et al.
Readers will be aware of the paper by Shaun Marcott and colleagues, that they published a couple weeks ago in the journal Science. That paper sought to extend the global temperature record back over the entire Holocene period, i.e. just over 11 kyr back time, something that had not really been attempted before. The paper [...]
Climate change and consequences on the groud
The link between extreme weather events, climate change, and national security is discussed in Extreme Realities, a new episode in PBS’ series Journey To Planet Earth hosted by Matt Damon. The video features a number of extreme weather phenomena: hurricanes, tornadoes, floods, wild fires, and flooding. The discussion is about climate change and the consequences [...]

A new open thread – hopefully for some new climate science topics…
Urban Heat Islands and U.S. Temperature Trends
US temperature trends are not rising because of Urban Heat Island effects. New research using multiple datasets from Zeke Hausfather and other bloggers in collaboration with NCDC scientists.
2012 Updates to model-observation comparions
Time for the 2012 updates! As has become a habit (2009, 2010, 2011), here is a brief overview and update of some of the most discussed model/observation comparisons, updated to include 2012. I include comparisons of surface temperatures, sea ice and ocean heat content to the CMIP3 and Hansen et al (1988) simulations. First, a [...]

The Greenland melt
Last July (2012), I heard from a colleagues working at the edge of the Greenland ice sheet, and from another colleague working up at the Summit. Both were independently writing to report the exceptional conditions they were witnessing. The first was that the bridge over the Watson river by the town of Kangerlussuaq, on the [...]
