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…

Roy Spencer's UAH report for March

See also Dr. Christy’s report from yesterday here UAH Global Temperature Update for March 2012: +0.11 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly jumped up in March, 2012, to +0.11 deg. C. as La Nina conditions in the Pacific Ocean waned (click on the image for the full-size version):

UAH global temperature – holding steady in November

UAH Global Temperature Update for Nov. 2011: +0.12 deg. C By Dr. Roy Spencer The global average lower tropospheric temperature anomaly for November, 2011 remained about the same as last month, at +0.12 deg. C (click on the image for the full-size version): The 3rd order polynomial fit to the data (courtesy of Excel) is…

Global Warming Potentials

Global Warming Potentials fail because gas concentrations are not “well-mixed” Guest post by Dr. Vincent Gray I came across this revealing statement on page 247 of the IPCC Third Assessment Report (2001). paragraph 4.1.4. Chapter 4 “The atmospheric lifetime is truly a scale factor relating (i) constant emissions (Tg/yr) to a steady-state burden (Tg), or…
