Marginal Parasitic Loss Rates

Guest Post by Willis Eschenbach There is a more global restatement of Murphy’s Law which says “Nature always sides with the hidden flaw”. Parasitic losses are an example of that law at work. In any heat engine, either natural or manmade, there are what are called “parasitic losses”. These are losses that tend to reduce…

Water Vapor Feedback

Guest Post by Willis Eschenbach Well, another productive ramble through the CERES dataset, which never ceases to surprise me. This time my eye was caught by a press release about a new (paywalled) study by Gordon et al. regarding the effect of water vapor on the climate: From 2002 to 2009, an infrared sounder aboard…

Three Clocks

Guest Post by Willis Eschenbach I got to wandering through the three main datasets that make up the overall CERES data, and I noticed an odd thing. The three main datasets are the all-sky downwelling solar, upwelling reflected solar, and upwelling longwave radiation, measured in watts per square metre (W/m2). Here are those three datasets:…

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…

CO2 and CERES

Guest Post by Willis Eschenbach The Intergovernmental Panel on Climate Change, the bureaucratic agency which appropriated the role of arbiter of things climatic, has advanced a theory for the lack of warming since the turn of the century, viz: The observed reduction in warming trend over the period 1998–2012 as compared to the period 1951–2012,…

Upwelling Solar, Upwelling Longwave

Guest Post by Willis Eschenbach The CERES dataset contains three main parts—downwelling solar radiation, upwelling solar radiation, and upwelling longwave radiation. With the exception of leap-year variations, the solar dataset does not change from year to year over a few decades at least. It is fixed by unchanging physical laws. The upwelling longwave radiation and…
