Today… Jim and I were painting.
Jim went to take his mother to church.
I visited James Annan’s blog and discovered “A Comment on ‘Heat Capacity, Time Constant and Sensitivity of Earth’s Climate System’” will be published. (I briefly examined the implications of their equation (4) to what I would estimate for the time constant of […]

Don J. Easterbrook, a retired professor from the Dept. of Geology, Western Washington University, in Bellingham, WA sent Anthony Watts a brief analysis of the effect of the PDO on climate:
Dr. Easterbrook’s analysis (PDF). The analysis included two figures: a) a graphic illustrating the PDO over time, and b) Dr. Easterbrooks projection for […]

This article is motivated by Martin Ringo’s rather important question:
I guess I just don’t understand why the change in temperature should be a constant or a constant plus noise. It would seem to imply an exponential growth, upward or downward, of temperature. What am I missing here?

The current falsification of the 2 C/century based on 6 years and 1 […]

Raven drew my attention to something posted at NASA GISS, which implies that, for all practical purposes, normal variations in solar irradiance don’t affect their predictions of future warming trends.
On their web site discussing 2007 temperatures, NASA GISS displays a figure showing the variation in solar irradiance measured over time. I’ve reproduced […]

One of the nice things about Climate Audit is the rapid discussion and the mild amount of editing. At the same time, Steve M likes many discussions to stay on topic, so as to […]
