Can We Tell If The Oceans Are Warming?

Guest Post by Willis Eschenbach Well, I was going to write about hourly albedo changes, honest I was, but as is often the case I got sidetractored. My great thanks to Joanne Nova for highlighting a mostly unknown paper on the error estimate for the Argo dataset entitled On the accuracy of North Atlantic temperature and…

Things In General

Guest Post by Willis Eschenbach My business card gives my job title as “Generalist”. Let me give you an example of why this is an advantage in climate science. I worked for a while in the field of low-tech renewable energy. One of the things I did was to work with inexpensive solar water heating. Using…

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…

Finally Some Reality from RealClimate – But, Unfortunately, They Remained Unreal about Some Things

Guest Post by Bob Tisdale The post Ocean heat storage: a particularly lousy policy target + Update at RealClimate finally presented a few realities of the global-warming metric known as ocean heat content—realities we have discussed numerous times.  But they weren’t completely open about it and the other ocean temperature-related dataset, sea surface temperature. That…

With ARGO, There is a Wide Range Warming (and Cooling) Rates of the Oceans to Depths of 2000 Meters

Guest Post by Bob Tisdale The KNMI Climate Explorer has added a number of datasets to their Monthly observations webpage, where users select desired data based on global coordinates. (Many thanks to Dr. Geert Jan van Oldenborgh of KNMI.)  The new datasets include, under the heading of Ocean mean temperature, the National Oceanographic Data Center…
