Cooling Deep Oceans – and the Earth’s General Background Temperature

Guest Post by Wim Röst Introduction Five million years ago, average temperatures were higher than they are now. During the Pliocene, the era just before the period of the Quaternary Ice Ages, ‘glacials’ did not yet exist because temperatures were too high. As cooling of the deep seas continued, temperatures became that low that large…

Hoegh-Guldberg’s Coral Sophistry Triggers Sagan’s Science Baloney Alert!

Guest essay by Jim Steele Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism Recently The Australian published an article by Graham Lloyd, “Great Barrier Battleground Over Coral Bleaching”. Lloyd quotes 2 of Hoegh-Guldberg’s claims that are not quite an honest representation…

The Coral Bleaching Debate: Is Bleaching the Legacy of a Marvelous Adaptation Mechanism or A Prelude to Extirpation?

Guest essay by Jim Steele Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism A Warm Evolutionary Legacy Despite increasing confirmation of the Adaptive Bleaching Hypothesis and its ability to explain coral resilience, most people are unaware of its debate within the…

"Phytoplankton rapidly disappearing from the Indian Ocean" or not.

  Guest post by David Middleton, feature image borrowed from iHerb. A rapid loss of phytoplankton threatens to turn the western Indian Ocean into an “ecological desert,” a new study warns. The research reveals that phytoplankton populations in the region fell an alarming 30 percent over the last 16 years.

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 variables like say latitude and elevation. We all know that as we go poleward it gets colder, and the same is true when we go…

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 what happens when the early morning (midnight to 5:00 AM) of a given day is cooler than usual, versus what happens when the early morning…

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 temperature threshold predictions Recent forecasts on the impacts of climate change on the world’s coral reefs–especially ones generated from oceanic surface temperature data gathered by…

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…
