Our annual post related to the comparisons between long standing records and climate models. As frequent readers will know, we maintain a page of comparisons between climate model projections and the relevant observational records, and since they are mostly for the global mean numbers, these get updated once the temperature products get updated for the prior full year. This has now been … Read Full Article about 2022 updates to model-observation comparisons

2022 updates to the temperature records
Another January, another annual data point. As in years past, the annual rollout of the GISTEMP, NOAA, HadCRUT and Berkeley Earth analyses of the surface temperature record have brought forth many stories about the long term trends and specific events of 2022 - mostly focused on the impacts of the (ongoing) La Niña event and the litany of weather extremes (UK and elsewhere having record years, … Read Full Article about 2022 updates to the temperature records

New misguided interpretations of the greenhouse effect from William Kininmonth
I have a feeling that we are seeing the start of a new wave of climate change denial and misrepresentation of science. At the same time, CEOs of gas and oil companies express optimism for further exploitation of fossil energy in the wake of Russia’s invasion of Ukraine, at least here in … Read Full Article about New misguided interpretations of the greenhouse effect from William Kininmonth
The established ground and new ideas
Science is naturally conservative and the scepticism to new ideas ensures high scientific quality. We have more confidence when different scholars arrive at the same conclusion independently of each other. But scientific research also brings about discoveries and innovations, and it typically takes … Read Full Article about The established ground and new ideas

The water south of Greenland has been cooling, so what causes that?
Let’s compare two possibilities by a back-of-envelope calculation. (1) Is it due to a reduced heat transport of the Atlantic Meridional Overturning Circulation (AMOC)? (2) Or is it simply due to the influx of cold meltwater as the Greenland Ice Sheet is losing ice? The latter is often … Read Full Article about The water south of Greenland has been cooling, so what causes that?

The #ConcordOslo2022 workshop
In recent years, the idea of climate change adaptation has received more and more attention and has become even more urgent with the unfolding of a number of extreme weather-related calamities. I wrote a piece on climate change adaptation last year here on RealClimate, and many of the issues that I … Read Full Article about The #ConcordOslo2022 workshop
Scafetta comes back for more
[latexpage] A new paper from Scafetta and it's almost as bad as the last one. Back in March, we outlined how a model-observations comparison paper in GRL by Nicola Scafetta () got wrong basically everything that one could get wrong (the uncertainty in the observations, the internal variability … Read Full Article about Scafetta comes back for more
