Is the Bern Model Non-Physical?

Guest essay by Joe Born Is the Bern Model non-physical? Maybe, but not because it requires the atmosphere to partition its carbon content non-physically. A Bern Model for the response of atmospheric carbon dioxide concentration to anthropogenic emissions is arrived at by adopting the values of , (and maybe ) that make the best fit…

An Engineer’s Take on Climate Change #2

Guest essay by Ronald D. Voisin High Atmospheric CO2 is Good for All Life on Earth At an atmospheric concentration of 380ppm and higher the limited long-wave spectral absorption of CO2 is essentially saturated. Consequently, yet more atmospheric CO2 becomes vanishingly less relevant to a greenhouse effect (if at all). And when more atmospheric water…

A case of the vapors – another global cooling mechanism found

From the University of Manchester Organic vapors affect clouds leading to previously unidentified climate cooling University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world’s climate by making clouds brighter. Clouds are made of water droplets, condensed…

By WUWT regular “Just The Facts” In the US we are currently being bombarded with claims that “this summer is ‘what global warming looks like’” from the Associated Press and “summer heat wave an early indication of global warming” from MSNBC, as well as insinuations like “Record heat, derecho storm: Does global warming get blame?”…

A Big Picture Look At “Earth’s Temperature” – Peter Gleick Edition

By WUWT regular “Just The Facts” I recently came across a January 21st, 2012 Peter Gleick article 2011 Climate Change in Pictures and Data: Just the Facts, which appears to mimic the format and approach of my January 1st, 2012 article A Big Picture Look At “Earth’s Temperature”. What I find particularly amusing about Peter’s article…
