Was Extreme Ultraviolet an Andy Warhol Actress?

Guest Post by Willis Eschenbach When folks tell me that the sunspot-related changes in total solar irradiance make changes down here on the surface of our amazing planet, I suggest that they take a look at the numbers. From peak to trough over the sunspot cycle, the top-of-atmosphere total solar irradiance varies by about 1.2…

What’s Absorbing The Sun?

Guest Post by Willis Eschenbach In considering how the energy flows around the planet, I got to thinking about the amount of solar energy that is absorbed rather than transmitted by the atmosphere and the clouds. As with many other such questions, I turned to the wonderful CERES satellite data. Figure 1 shows what CERES…

Of Water And Albedo

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 gas in the modeled atmosphere were modeled water, the model world would basically evolve to a…

The La Nina Pump

Guest Post by Willis Eschenbach Sometimes a chance comment sets off a whole chain of investigation. Somewhere recently, in passing I noted the idea of the slope of the temperature gradient across the Pacific along the Equator. So I decided to take a look at it. Here is the area that I examined. Figure 1.…

The Green Spent By The Green Climate Fund

Guest Post by Willis Eschenbach When President Trump pulled the US out of the Paris Climate Agreement, he also pulled us out of paying any additional money to the so-called “Green Climate Fund” (GCF). Sorry, no more green for the greenies’ fund. This is the fund which has been given $7.2 billion dollars of taxpayer…

Dr. Hansen’s Statistics

Guest Post by Willis Eschenbach OK, this post has ended up having two parts, because as usual, I got side-tractored while looking at the first part. It’s the problem with science, too many interesting trails leading off the main highway … Part The First I wanted to point out an overlooked part of Dr. James…

Stacking Up Volcanoes

  Guest Post by Willis Eschenbach [See Update at end] As readers of my posts know, I’ve held for many years that there are a variety of emergent phenomena that regulate the earth’s temperature. See my posts The Thermostat Hypothesis and Emergent Climate Phenomena for an overview of my hypothesis. One of the predictions derivable…

The Thirty Year War

Guest Post by Willis Eschenbach This is the 30th anniversary of James Hansen’s testimony to Congress regarding “global warming”. It was his testimony that set off the disastrous 30 Year War on Carbon. There have been articles in the press celebrating the anniversary of his testimony and lauding Hansen’s role, but I see nothing to…

MLO and MEI

Guest Post by Willis Eschenbach In my last post, which was about the Mauna Loa Observatory (MLO) in Hawaii, Dr. Richard Keen and others noted that for a good comparison, there was a need to remove the variations due to El Nino. Dr. Keen said that he uses the Multivariate ENSO Index (MEI) for such…

When Eruptions Don’t

Guest Post by Willis Eschenbach Inspired by Richard Keen’s interesting WUWT post on using eclipses to determine the clarity of the atmosphere, I went to the website of the Hawaiian Mauna Loa Observatory. They have some very fascinating datasets. One of them is a measurement of direct solar radiation, minute by minute, since about 1980. I…
