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…

Learning From The Argonauts

Guest Post by Willis Eschenbach The best thing about doing climate science the way I do it is that I can study anything I want, and there is always so much more to learn … in the present instance, there’s another year of Argo data, so I thought I’d take another stroll through the world…

Trenberth Still Searching for Missing Heat

Kevin Trenberth is one of the authors of new Balmaseda et al (2013) paper Distinctive climate signals in reanalysis of global ocean heat content. I find the title of the paper somewhat odd. The paper is based on the European Centre for Medium-Range Weather Forecasts (ECMWF) Ocean Reanalysis ORAS4. That reanalysis is described in detail…

Ocean Temperature And Heat Content

Guest Post by Willis Eschenbach Anthony has an interesting post up discussing the latest findings regarding the heat content of the upper ocean. Here’s one of the figures from that post. Figure 1. Upper ocean heat content anomaly (OHCA), 0-700 metres, in zeta-joules (10^21 joules). Errors are not specified but are presumably one sigma. SOURCE …
