An alternate theory for the terrestrial ice-age trigger

[Note: This essay discusses a theory that some people might consider as impossible, and it may very well be, even though there is some support for the idea that continental position plays a role in major ice ages. As seen below, Milankovitch cycles resulting in insolation variance is a leading theory that seems much more…

NASA revises Earth’s Radiation Budget, diminishing some of Trenberth’s claims in the process

From the “settled science” department comes this new revision of Earth’s entire radiation budget. Many WUWT readers can recall seeing this radiation budget graphic from Kenneth Trenberth in 2009: Source: Trenberth et al. 2009 http://echorock.cgd.ucar.edu/cas/Staff/Fasullo/my_pubs/Trenberth2009etalBAMS.pdf That figure in a slightly different form also appeared in the 2007 IPCC AR4 WG1 report with different numbers: 

Climate as a heat engine

Guest essay by Jan Kjetil Andersen As Willis describes in his article on December 21, the atmosphere can be seen as a gigantic heat engine, i.e. a machine which convert thermal energy, namely temperature, into mechanical energy, namely wind. It may seem a bit strange to view the weather system as a kind of machine…

Earth’s self regulation of Carbon Dioxide is remarkably stable

From CSIRO: “What we learned is that in spite of droughts, floods, volcano eruptions, El Niño and other events, the Earth system has been remarkably consistent in regulating the inter-annual variations in atmospheric carbon dioxide levels,” Tropical ecosystems regulate variations in Earth’s carbon dioxide levels Rising temperatures, influenced by natural events such as El Niño,…

Length of day governed by Earth’s core processes

From the University of Liverpool , something I found interesting because a few years ago, former State Climatologist Jame Goodridge said he saw correlations between length of day and other atmospheric processes. Research reveals Earth’s core affects length of day Research at the University of Liverpool has found that variations in the length of day…

Claim: Faint Young Sun Paradox solved

From the University of Colorado at Boulder a claim that computer modeling has solved the problem, with an atmosphere that is 20,000 parts per million of  CO2 and 1,000 ppm of methane. CU study shows how early Earth kept warm enough to support life Scientists tackle faint young sun paradox with 3-D climate models Solving…
