Clouds and El Nino

Guest Post by Willis Eschenbach After the turn of the century, I became interested in climate science. But unlike almost everyone else, I wasn’t surprised by how much the global temperature was changing. As someone with experience with heat engines and engine governors, I know how hard it is to keep a heat engine stable…

A New Index to Willis’s Posts

Guest Post by Willis Eschenbach Well, my old index to my posts was out of date, and I finally got tired of not being able to find things that I’ve written. This is me trying to figure it out. So I wrote a program in the computer language “R”. It takes as input a list…

Cooling and Warming, Clouds and Thunderstorms

Guest Post by Willis Eschenbach Following up on a suggestion made to me by one of my long-time scientific heroes, Dr. Fred Singer, I’ve been looking at the rainfall dataset from the Tropical Rainfall Measuring Mission (TRMM) satellite. Here’s s the TRMM average rainfall data for the entire mission to date: Figure 1. Average annual…

The Thermostatic Throttle

Guest Post by Willis Eschenbach I have theorized that the reflective nature of the tropical clouds, in particular those of the inter-tropical convergence zone (ITCZ) just above the equator, functions as the “throttle” on the global climate engine. We’re all familiar with what a throttle does, because the gas pedal on your car controls the…

Evidence that Clouds Actively Regulate the Temperature

Guest Post by Willis Eschenbach I have put forth the idea for some time now that one of the main climate thermoregulatory mechanisms is a temperature-controlled sharp increase in albedo in the tropical regions. I have explained that this occurs in a stepwise fashion when cumulus clouds first emerge, and that the albedo is further…

Further Evidence for my Thunderstorm Thermostat Hypothesis

Guest Post by Willis Eschenbach For some time now I’ve been wondering what kind of new evidence I could come up with to add support to my Thunderstorm Thermostat hypothesis (q.v.). This is the idea that cumulus clouds and thunderstorms combine to cap the rise of tropical temperatures. In particular, thunderstorms are able to drive…

An Index to Willis's Writings

Guest Post by Willis Eschenbach. In an effort to make some sense out of my posts and to enable me to refer to them and remember where they are located and what they are about, I put together a list by category, along with a short description of each one. Figure 1. I try to…

The Thermostat Hypothesis

Guest Essay by Willis Eschenbach Abstract The Thermostat Hypothesis is that tropical clouds and thunderstorms actively regulate the temperature of the earth. This keeps the earth at a equilibrium temperature. Several kinds of evidence are presented to establish and elucidate the Thermostat Hypothesis – historical temperature stability of the Earth, theoretical considerations, satellite photos, and…

Of Water And Albedo

Guest Post by Willis Eschenbach As usual, there is more to learn in the CERES satellite dataset. I got to thinking of the idea put forth by Lacis 2010. He announced model results claiming that if the only modeled greenhouse gas in the modeled atmosphere were modeled water, the model world would basically evolve to a…
