Of Water And Albedo

By Willis Eschenbach – Re-Blogged From WUWT

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 modeled ice over condition at a modeled -20°C (-4°F). Here is his money graph, showing the evolution of various modeled climate measurements in the first fifty modeled years after removing all modeled GHGs except for modeled water from the modeled atmosphere. See his paper for details.

Climatology’s Startling Error – An Update

By Christopher Monckton of Brenchley – Re-Blogged From WUWT

Well, we sent out our paper On an error in defining temperature feedback to a leading journal for review. The reviewers did not like it at all. “And, gracious! How Lord Lundy cried!”

We are persevering, though, for in our submission nothing the reviewers have said in any way undermines the scientific validity of our result, which I outlined here in a series some months back.

Cloud Feedback

By Willis Eschenbach – Re-Blogged From http://www.WattsUpWithThat.com

In the comments to Christopher Monckton’s latest post, Nick Stokes drew attention to Soden and Held’s analysis of feedback in the climate models. I reproduce their Table 1 below:

Figure 1. Soden and Held’s Table 1, showing all of the feedback parameters calculated from the models.

I found several amazing things in this table. The first is the huge range of values for the various parameters. While all of the Planck parameters are within a few percent of each other, the lapse rate feedback varies by more than three to one from smallest to largest; the surface albedo feedback varies by nearly five to one; and the cloud feedback varies by an amazing factor of more than eight to one from smallest to largest.
