Antarctic melting slows atmospheric warming and speeds sea level rise

From Eurekalert Public Release: 19-Nov-2018 The research is the first to show how the melting of the Antarctic ice sheet will affect future climate University of Arizona As the Antarctic ice sheet melts, warming of the atmosphere will be delayed by about a decade but sea level rise will accelerate, according to new research scheduled…

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…

A Big Picture Look At “Earth’s Temperature” – "Extreme Weather" Update

By WUWT regular “Just The Facts” Recently there have been increased efforts to link “Climate Change” and “Extreme Weather” e.g., NOAA links extreme weather to climate change CBS – July 10, 2012, “NASA scientist links climate change, extreme weather” CNN – August 6, 2012 and Get used to ‘extreme’ weather, it’s the new normal The…

NASA: High-Altitude Haze and Vortex At South Pole of Saturn's Moon Titan

PASADENA, Calif. — Images from NASA’s Cassini spacecraft show a concentration of high-altitude haze and a vortex materializing at the south pole of Saturn’s moon Titan, signs that the seasons are turning on Saturn’s largest moon. “The structure inside the vortex is reminiscent of the open cellular convection that is often seen over Earth’s oceans,”…

A Big Picture Look At “Earth’s Temperature” – 2nd Quarter, 2012 – "What Global Warming Looks Like" Update

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…

A Big Picture Look At “Earth’s Temperature” – Quarterly Update

By WUWT regular “Just The Facts” This format received a positive response in the previous article and apparently encouraged Skeptical Science to take A Big Picture Look at Global Warming, thus this article will be updated on a quarterly basis moving forward. In their article, Skeptical Science argued that “the planet is indeed warming rapidly”…

Extremely Black Carbon

Guest Post by Willis Eschenbach Of late there has been a lot written about the effect of “black carbon”, a.k.a. “soot”, and also “brown carbon”, a.k.a. wood and dung smoke, on the climate. Me, I think it’s worthwhile controlling black and brown carbon solely because of the health effects. Inhaled soot and wood smoke kill…
