Arctic Layer Cake

Guest Post by Willis Eschenbach There’s a recent paper paywalled here, called Arctic winter warming amplified by the thermal inversion and consequent low infrared cooling to space. Fortunately, the Supplementary Online Information is available here, and it contains much valuable information. The paper claims that during the arctic winter, the atmospheric radiation doesn’t go out to…

New paper: Arctic amplification of temperature not primarily due to albedo changes, climate models need to be reworked

From the Max Planck Institute for Meteorology: Climate changes faster in the Arctic than anywhere else on Earth, a phenomenon that is often explained by retreating snow and ice leading to more solar surface warming (positive ice-albedo-effect). In a new study in Nature Geoscience the scientists Felix Pithan and Dr. Thorsten Mauritsen from the department…

U.S. Dec/Jan Temperatures 3rd Coldest in 30 Years

by Roy W. Spencer, Ph. D. Yes, Virginia, it really has been a cold winter. The winter months of December 2013 and January 2014 averaged over the contiguous 48 United States were the 3rd coldest Dec/Jan in the last 30 years. The analysis is based upon ~350 NOAA/NWS stations that measure temperatures every 6 hours…
