New Paper On The Need For Improved Cloud Representation In Climate Models By Wang Et Al 2009
Yesterday, I discussed the issue that water vapor feedbacks are more poorly understood than indicated in the papers by Andrew Dessler (see). Today, I have provided a new paper that discusses one aspect of the current inability of the multi-decadal … Continue reading

New Paper “Temperature And Equivalent Temperature Over The United States (1979 – 2005) By Fall Et Al 2009
We have a new paper that documents the need to include water vapor trends, in addition to temperature trends, in the assessment of climate system heat changes (which, of course, includes global warming). Our paper is Fall, S., N. Diffenbaugh, D. … Continue reading

Further Comments on The Inadequate EPA Response To Reviewer Comments On Ocean Heat Content
UPDATE: Decmber 28 2009: The source of the descrepancy between the 0.77 Watts per meter squared reported by von Schuckmann et al and the 0.47 Watts per meter squared that I calculated is that my value distributed this heating over the global … Continue reading

Q & A – The Role Of Landscape Change and Other Human Climate Forcings Within the Climate System
I have been asked two very interesting and important questions by Bill DiPuccio which I paraphrase and summarize below: 1. What is the area of land that is directly modified by human landscape management? While it is clear that local and regional … Continue reading
