Hump Day Hilarity – model the bouncing ball

Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit like watching a ball bouncing down a rocky hillside. You can predict some aspects of it behaviour but not others. You can predict it will…

Claim: “golden age of climate science, models” is upon us

Latest Supercomputers Enable High-Resolution Climate Models, Truer Simulation of Extreme Weather Berkeley Lab researcher says climate science is entering a new golden age. Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using some of the most powerful supercomputers now available, Lawrence Berkeley National…

On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison

Guest Post by Bob Tisdale With the publication of the IPCC 5th Synthesis Report, I thought there might be some interest in a presentation of how well (actually poorly) climate models simulate global mean surface temperatures in absolute terms. That is, most climate model outputs are presented in terms of anomalies, with data shown as…
