Arctic temperature anomaly uncertainties

Dr. Roger Pielke Sr. writes of a new paper which suggest that Arctic temperaturehas even greater uncertainty problems. He writes (excerpts) New Paper “A Multi-Data Set Comparison Of The Vertical Structure Of Temperature Variability And Change Over The Arctic During The Past 100 Years” By Brönnimann, et al 2012 I was alerted to a new paper on…

May UAH Global Temperature – unchanged

UAH Global Temperature Update for May 2012: +0.29°C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for May 2012 (+0.29 °C) changed little from April (+0.30 °C), with some warming to near-average temperatures in the tropics being balanced by a little cooling in the Southern Hemisphere (click on the image for the…

UAH Global temperature, up in April

UAH Global Temperature Update for April 2012: +0.30°C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly increased again in April, 2012, to +0.30°C., with warming in both Northern and Southern Hemispheres, but slightly cool conditions persisting in the tropics (click on the image for the full-size version): The corresponding April anomaly from…

A Tale of Two Altitudes: how stratospheric temperature is de-coupled from the surface temperatures

On the battle between Arrhenius and Ångström. Story submitted by John Kehr, The Inconvenient Skeptic Any serious discussion about the Theory of Global Warming will eventually include the absorption band argument that started more than 100 years ago between Arrhenius and Ångström.  One of the arguments presented by Ångström was that the main CO2 absorption…
