Argo And Ocean Heat Content

Guest Post by Willis Eschenbach Today I ran across an interesting presentation from 2013 regarding the Argo floats. These are a large number of independent floats spread all across the world oceans. They spend most of their time sleeping at a depth of 1,000 metres (3,300 feet) below the surface of the ocean. Then they drop…

Changes in Total Solar Irradiance

Total solar irradiance, also called “TSI”,  is the total amount of energy coming from the sun at all frequencies. It is measured in watts per square metre (W/m2). Lots of folks claim that the small ~ 11-year variations in TSI are amplified by some unspecified mechanism, and thus these small changes in TSI make an…

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,…
