U.S. Climate Resilience Tool Kit: Greenland Stays Frozen in 2100… Even Under RCP8.5

Guest DIY by David Middleton It looks like at least some of this money was well-spent. I stumbled across something very useful yesterday on Climate-Dot-Gov’s U.S. Climate Resilience Tool Kit page. The widget generates CMIP5 or PMIP3 model outputs for specific countries and a temperature change map of the world.  You can also spit out…

EXAMPLES OF HOW AND WHY THE USE OF A “CLIMATE MODEL MEAN” AND THE USE OF ANOMALIES CAN BE MISLEADING

THE POST HAS BEEN UPDATED.  SEE THE UPDATE AT THE END OF THE POST: Alternate Title: An Average of Climate Models, Which Individually Give Wrong Answers, Cannot, By Averaging Them, Give the Right Answer, So A Model Mean Can Be Very Misleading. And The Use of Anomalies in Model-Data Comparisons, When Absolute Values Are Known,…

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…

NASA finds something else climate models are missing…. forcing from 'Secondary Organic Aerosols'

A new paper published by NASA by Tsigaridis and Kanakidou suggests that climate models have missed the forcing effects of organic aerosols, such as VOC’s from trees, oceans, and other sources that combine chemically in the atmosphere to create new compounds. Known as Secondary organic aerosols (SOA), they say “SOA forcing could exceed that of sulfate…

New "simplified" Russian climate model promises faster results

From KAZAN FEDERAL UNIVERSITY and the “Russian Collusion Department” First results were published in Geoscientific Model Development. Professor Aleksey Eliseev, Chief Research Associate at Kazan University’s Near Space Research Lab, comments, “To find solutions for some tasks in climate research, we need calculations for hundreds, thousands, or even millions of years. Such tasks are, for example, ice…
