Interesting finding: coral bleaching less where ocean temp variations are large

Bleaching of coral reefs reduced where daily temperature changes are large By taking a closer look, UCI scientists find resilience in face of heat stress Coral reef bleaching is stark…

The 60-year oscillation revisited

Guest Post by Javier It is a well-known feature of climate change that since 1850 multiple climate datasets present a ~ 60-year oscillation. I recently wrote about it in the…

What's Hot, What's Not

Guest Post by Willis Eschenbach I got to thinking about the idea of a temperature field. By that I mean nothing more than an estimation of theoretical temperatures given some…

TAO Buoys Go Hot And Cold

Guest Post by Willis Eschenbach I got to thinking about how I could gain more understanding of the daily air temperature cycles in the tropics. I decided to look at…

New climate stress index model challenges doomsday forecasts for world's coral reefs

Believe it or not, that’s the actual headline from the Wildlife Conservation Society press release. This model they tout incorporates field data. – Anthony Complex model performs better than common…

Things In General

Inconvenient study: La Niña killed coral reefs 4100 years ago and lasted over two millennia

From Georgia Tech and the “it’s your SUV that’s killing the coral reefs today, why can’t you get that through your head” department comes this inconvenient study. La Nina-like conditions…

The CERES Calculated Surface Datasets

Guest Post by Willis Eschenbach The CERES dataset is satellite data that is based on radiation measurements made from low earth orbit. The CERES data has two parts. The first…

TAO And TAO Again

Guest Post by Willis Eschenbach Impelled by my restless curiosity, I’ve returned to the TAO buoy dataset to investigate a claim by Dr. Ramanathan of a “super-greenhouse” effect. The TAO…

Ocean 'Global Warming' is not actually 'global' at all

UPDATE: I forgot to note that the data in Figure 1 have been zeroed at the year 2003. That was done to simplify the illustration. # # # The National…

Arguments For and Against Human-Induced Ocean Warming

Guest Post by Bob Tisdale UPDATE: Corrected the percentage of ocean heat loss though evaporation. Update 2: Added a link to a post by Willis Eschenbach at the end, and…
