Model claim: airplanes of the future won’t be able to take off at some airports due to global warming

Density altitude is the biggest factor in aircraft take off on a given runway length, temperature, and altitude. I know this from firsthand experience as I used to be a private pilot – until my hearing got so bad that I decided I was a danger to myself and others. This study published in the…

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…

A Simple Truth; Computer Climate Models Cannot Work

Guest opinion by Dr. Tim Ball – Ockham’s Razor says, “Entities are not to be multiplied beyond necessity.” Usually applied in making a decision between two competing possibilities, it suggests the simplest is most likely correct. It can be applied in the debate about climate and the viability of computer climate models. An old joke…

‘Icebergs once drifted to Florida’

From the University of Massachusetts at Amherst and the department of melted evidence, comes this interesting story about the last ice age. Icebergs once drifted to Florida, new climate model suggests The first study to show that when the large ice sheet over North America known as the Laurentide ice sheet began to melt, icebergs…
