Guest Post by Willis Eschenbach Some days I learn a lot. Today was one of them. Let me start at the start. Back in 1987 in a paper entitled ‘The Role of Earth Radiation Budget Studies in Climate and General Circulation Research“, a prescient climate scientist yclept Veerabhadran Ramanathan pointed out that the poorly-named “greenhouse…
Guest Post by Willis Eschenbach My last two posts, one on Gavin’s claims and the other on the Urban Heat Island (UHI) effect, have gotten me to thinking about the various groups producing historical global surface temperature estimates. Remember that the global surface temperature is the main climate variable that lots of folks are hyperventilating…
Guest Post by Willis Eschenbach Gavin Schmidt is a computer programmer with the Goddard Institute of Space Sciences (GISS) and a noted climate alarmist. He has a Ph.D. in applied mathematics. He’s put together a twitter thread containing what he sees as some important points of the “testable, falsifiable science that supports a human cause…
Guest Post by Willis Eschenbach [OK, had to start over, had bad numbers for the areas. Graphics have been replaced. I was using “core area” but I should have been using “greater metropolitan area”. All conclusions are unchanged.] I got to thinking about the phenomenon known as the “Urban Heat Island” effect, or UHI. Cities…
Guest Post by Willis Eschenbach [see update at the end] How much is a “Whole Little”? Well, it’s like a whole lot, only much, much smaller. There’s a new paper out. As usual, it has a whole bunch of authors, fourteen to be precise. My rule of thumb is that “The quality of research varies…
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 rewrite of the post entitled “THE THUNDERSTORM THERMOSTAT HYPOTHESIS: HOW CLOUDS AND THUNDERSTORMS CONTROL THE EARTH’S TEMPERATURE“. When I started…
Guest Post by Willis Eschenbach I kept hearing so much about the Australian bushfires being the result of or driven by “climate change” or “global warming” that I thought I’d take a look at just what’s happened to the rainfall there. Here are a hundred and nineteen years of Australian rainfall. Here’s the curious part.…
Guest Post by Willis Eschenbach I take as my subject for this post a claim made over at Forbes Magazine, viz: I saw that and said “Whaaaa”? My urban legend detector light started flashing bright red at that claim that we’re on the primrose path to the epocalypse. Me, I always want to go the…
People sometimes ask me why I don’t believe the endless climate/energy use predictions of impending doom and gloom for the year 2050 or 2100. The reason is, neither the climate models nor the energy use models are worth a bucket of warm spit for such predictions. Folks concentrate a lot on the obvious problems with…
Guest Post by Willis Eschenbach I got to thinking about the lack of progress in estimating the “equilibrium climate sensitivity”, known as ECS. The ECS measures how much the temperature changes when the top-of-atmosphere forcing changes, in about a thousand years after all the changes have equilibrated. The ECS is measured in degrees C per…
