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…

Global warming and unforced variability: Clarifications on recent Duke study

Guest Commentary from Patrick Brown and Wenhong Li, Duke University We recently published a study in Scientific Reports titled. Our study seemed to generated a lot of interest and we have received many inquires regarding its findings. We were pleased with some of coverage of our study (e.g., here) but we were disappointed that […]

How long does it take Antarctica to notice the Northern Hemisphere is warming?

Eric Steig A series of large and abrupt climate changes occurred during the last ice age, most clearly expressed in ice cores from Greenland and other paleoclimate data rom the circum-North-Atlantic region. Since the discovery of these events, we’ve been trying to pin down the timing of abrupt climate changes elsewhere on the globe. Were […]

Nenana Ice Classic 2015

Unsurprisingly to anyone looking at the exceptionally warm winter on the West Coast of North America, the Nenana Ice Classic had another near-record early breakup on Friday, netting some lucky winner(s) around $300,000 in prizes. As I’ve discussed previously (last year and an update), the Ice Classic is a lottery that has been run every […]

The return of the iris effect?

Guest commentary from Andy Dessler (TAMU) When a new scientific hypothesis is published, two questions always occur to me: Did the authors convincingly show the hypothesis was correct? If not, is the hypothesis actually correct? The answers to these two questions may not be the same. A good example is Wegener’s theory of continental drift […]

An Online University Course on the Science of Climate Science Denial

Guest post from John Cook, University of Queensland For many years, RealClimate has been educating the public about climate science. The value of climate scientists patiently explaining the science and rebutting misinformation directly with the public cannot be overestimated. When I began investigating this issue, my initial searches led me here, which was invaluable in […]

A Scientific Debate

Guest posting from Bill Ruddiman, University of Virginia Recently I’ve read claims that some scientists are opposed to AGW but won’t speak out because they fear censure from a nearly monolithic community intent on imposing a mainstream view. Yet my last 10 years of personal experience refute this claim. This story began late in 2003 […]
