A Tropical Oddity

Posted on February 1, 2013 by

Guest Post by Willis Eschenbach I wanted to bring you up to date on my current meanderings in the TAO buoy data that I investigated previously in a post called “Cloud Radiation Forcing in the TAO Dataset“. In my peripatetic … Continue reading →

Greenland Ice Sheet albedo drops ‘off the bottom of the chart’ – but look closer as to why

Posted on July 21, 2012 by

Got this in the mail just as I posted my open thread announcemnt. I’m too busy this weekend to say much else except to post this tweet from Bill McKibben and some past blog excerpts and invite discussion. Bill McKibben … Continue reading →

A Demonstration of Negative Climate Sensitivity

Posted on June 19, 2012 by

Guest Post by Willis Eschenbach Well, after my brief digression to some other topics, I’ve finally been able to get back to the reason that I got the CERES albedo and radiation data in the first place. This was to … Continue reading →

Observations on TOA Forcing vs Temperature

Posted on June 12, 2012 by

I recently wrote three posts (first, second, and third), regarding climate sensitivity. I wanted to compare my results to another dataset. Continued digging has led me to the CERES monthly global albedo dataset from the Terra satellite. It’s an outstanding set, … Continue reading →

Sun and Clouds are Sufficient

Posted on June 4, 2012 by

Guest Post by Willis Eschenbach In my previous post, A Longer Look at Climate Sensitivity, I showed that the match between lagged net sunshine (the solar energy remaining after albedo reflections) and the observational temperature record is quite good. However, … Continue reading →

A Longer Look at Climate Sensitivity

Posted on May 31, 2012 by

Guest Post by Willis Eschenbach After I published my previous post, “An Observational Estimate of Climate Sensitivity“, a number of people objected that I was just looking at the average annual cycle. On a time scale of decades, they said, … Continue reading →

An Observational Estimate of Climate Sensitivity

Posted on May 29, 2012 by

Guest Post by Willis Eschenbach “Climate sensitivity” is the name for the measure of how much the earth’s surface is supposed to warm for a given change in what is called “forcing”. A change in forcing means a change in … Continue reading →

Earth’s baseline black-body model – “a damn hard problem”

Posted on January 12, 2012 by

By Robert G. Brown, Duke University (elevated from a WUWT comment) I spent what little of last night that I semi-slept in a learning-dream state chewing over Caballero’s book and radiative transfer, and came to two insights. First, the baseline … Continue reading →

Earth’s Albedo Tells an Interesting Story

Posted on October 17, 2007 by

Thanks to one of our commenters (thanks Henry), this unique project called “Earthshine” being done at the Big Bear Solar Observatory has been brought to my attention. The project is simple in concept: The Earth’s climate depends on the net … Continue reading →
