Guest Post by Willis Eschenbach Sadly, I’m in a disagreement with a very good man and a very good scientist, Dr. Roy Spencer. Dr. Roy and Dr. John Christy are…

Guest Post by Willis Eschenbach For a while now, I’ve been using a curious kind of scatterplot. Here’s an example. It shows the relationship between the surface temperature and the…

Guest Post by Willis Eschenbach I’m a visual guy. I understand numbers, but not in tables. I make them into graphs and charts and maps so I can understand what’s…

Guest Post by Willis Eschenbach We have an experiential understanding of the effect of radiation on objects. Oh, not nuclear radiation, that’s something different. I’m talking about things like solar…

Guest Post by Willis Eschenbach There’s an old saying about models—“All models are wrong, but some models are useful.” It’s often used to justify the existence of climate models. However,…

Guest Post by Willis Eschenbach I got to messing about with the MODTRAN Infrared Light In The Atmosphere model. From the Help file. Figure 1. Description of the MODTRAN model.…

Guest Post by Willis Eschenbach Well, for my sins I’ve been working on a paper with the hope of getting it published in a journal. Now that it’s nearly done,…

Guest Post by Willis Eschenbach My mind runs to curious corners of the climate question. I got to thinking about how little the atmospheric CO2 level has changed over most…

Guest Post by Willis Eschenbach Clouds are said to be the largest uncertainty in climate models, and I can believe that. Their representation in the models is highly parameterized, each…

Guest Post by Willis Eschenbach I ponder curious things. I got to thinking about available solar energy. That’s the amount of solar energy that remains after reflection losses.  Just under a third (~ 30%) of the...

Out in the webiverse someone asked me “Willis… do you consider yourself a denialist?” Mmmm … an excellent question, with an answer which likely won’t go the direction that they think...

Guest Post by Willis Eschenbach Eleven years ago I published a post here on Watts Up With That entitled “The Thermostat Hypothesis“. About a year after the post, the journal Energy and Environment published my...

Guest Post by Willis Eschenbach Let me start explaining the link from Picasso to climate science by looking at what Dr. Nir Shaviv called “the most boring graph I have ever plotted in my life”. This is the graph...

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...

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...
