A Stove Top Analogy to Climate Models

Reposted from Dr. Roy Spencer’s blog September 13th, 2019 by Roy W. Spencer, Ph. D. Have you ever wondered, “How can we predict global average temperature change when we don’t even know what the global average temperature is?” Or maybe, “How can climate models produce any meaningful forecasts when they have such large errors in…

Climate models are fudged, says climatologist – Video

Dr. Patrick Michaels, former Virginia State Climatologist has some strong comments about climate models during an interview with Mark Levin: “It is nowhere near as warm as it’s ‘supposed’ to be,” says climatologist Dr. Patrick Michaels. “The computer models are making systematic, dramatic errors.” There are 32 different computer models used to predict the climate,…

Northern Hemisphere snow cover trends (1967-2018): A comparison between climate models and observations

According to the climate models, snow cover should have steadily decreased for all four seasons. However, the observations show that only spring and summer demonstrates a long-term decrease. Ronan Connolly, Michael Connolly, Willie Soon, David R. Legates, Rodolfo Gustavo Cionco , and V. M. Velasco Herrera Abstract: Observed changes in Northern Hemisphere snow cover from…

New study attempts to “squeeze out” uncertainty in climate models

From the “we’re gonna need a bigger computer” department. Climate model uncertainties ripe to be squeezed The latest climate models and observations offer unprecedented opportunities to reduce the remaining uncertainties in future climate change, according to a new study. Although the human impact of recent climate change is now clear, future climate change depends on how…

Study: Another failure of climate models – they can’t handle barometric pressure change

One of the most basic meteorological factors isn’t handled by climate models – and they run off in a “hockey stick” style. From the UNIVERSITY OF LINCOLN Climate models fail to simulate recent air-pressure changes over Greenland Climatologists may be unable to accurately predict regional climate change over the North Atlantic because computer model simulations have…

Survey tries to assess the usefulness of climate models

From the INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES and the “all models are wrong, some might be useful” department. Researchers work toward systematic assessment of climate models A research team based at the Pacific Northwest National Laboratory in Richland, Wash., has published the results of an international survey designed to assess the relative importance climate scientists…

Study: Climate Models Need More Historical Fudge Factors

Guest essay by Eric Worrall The researchers claim adding historical data derived fudge factors to correct the discrepancy between climate models and historical observations, producing a Frankenmodel mix of fudge factors and defective physics, will make climate predictions more reliable. New approach to global-warming projections could make regional estimates more precise Computer models found to…
