Models v. Atmospheric Temperatures: Roy Spencer has further comments regarding the recalculated atmospheric temperatures recently produced by Mears and Wentz, who are principals in Remote Sensing Systems (RSS), competitors with the Earth System Science Center at the University of Alabama in Huntsville (UAH). Spencer points out that despite claims in the press, the new (more warming) RSS dataset does not resolve the discrepancy between observed temperature trends in the lower troposphere.
It is in the lower troposphere that greenhouse gas warming occurs. Discussions about surface warming or deep ocean warming are secondary to the issue: are greenhouse gases causing dangerous global warming? According to the greenhouse gas theory, and reports by the UN Intergovernmental Panel on Climate Change (IPCC), and its followers, this warming trend is to be most pronounced over the tropics (roughly 20 degrees South and North of the Equator. As Spencer writes “Even the New RSS Satellite Dataset Says the Models are Wrong.”
The new lower troposphere dataset “(Version 4, compared to Version 3.3) didn’t really change in the tropics.” Spencer produces a chart demonstrating how wrong the models are. See links under Challenging the Orthodoxy.
