From PNAS: Direct satellite observation reveals that the Arctic planetary albedo, a measure of reflectiveness, decreased from 0.52 to 0.48 between 1979 and 2011, a change in albedo that corresponds…

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…
Weekly Area of Snow Extent
Guest Post by Willis Eschenbach I got to thinking about snow the other day. It was occasioned by my look at the correlation (both positive and negative) of temperature and…
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…
A Tropical Oddity
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…
Greenland Ice Sheet albedo drops 'off the bottom of the chart' – but look closer as to why
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…
A Demonstration of Negative Climate Sensitivity
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…
Observations on TOA Forcing vs Temperature
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…
Sun and Clouds are Sufficient
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…
A Longer Look at Climate Sensitivity
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…
An Observational Estimate of Climate Sensitivity
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…
Earth's baseline black-body model – "a damn hard problem"
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…
Earth's Albedo Tells an Interesting Story
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…
