NASA Selects New Instrument to Continue Key Climate Record

From NASA Feb. 26, 2020 RELEASE 20-020 NASA Selects New Instrument to Continue Key Climate Record Earth’s outgoing longwave, or heat, radiation shown here as the average from 2000 to 2015 were measured by the Clouds and the Earth’s Radiant Energy System (CERES) instruments on NASA’s Aqua and Terra satellites. Bright yellow and orange indicate…

A Third Look at Radiation versus Temperature

Guest post by KEVIN KILTY Introduction In a post on June 8, 2019, Willis Eschenbach showed an interesting plot of monthly average surface temperature against total irradiance absorbed at the ground surface. He has updated this original post. His original figure is at the top of this post. He made no hypothesis about the meaning…

Northern Hemisphere snow cover trends (1967-2018): A comparison between climate models and observations

According to the climate models, snow cover should have steadily decreased for all four seasons. However, the observations show that only spring and summer demonstrates a long-term decrease. Ronan Connolly, Michael Connolly, Willie Soon, David R. Legates, Rodolfo Gustavo Cionco , and V. M. Velasco Herrera Abstract: Observed changes in Northern Hemisphere snow cover from…

The Size of Icy Reflections

Guest Post by Willis Eschenbach In my continuing wanderings through the regions cryospherical, I find more side roads than main highways. In my last two posts here and here, I discussed the curious inverse relationship between temperature and ice accumulation rates in Greenland and Antarctica. Wanting to understand the changes in the polar oceans that occur when…

What's Hot, What's Not

Guest Post by Willis Eschenbach I got to thinking about the idea of a temperature field. By that I mean nothing more than an estimation of theoretical temperatures given some variables like say latitude and elevation. We all know that as we go poleward it gets colder, and the same is true when we go…

Weather Two Months From Now

Guest Post by Willis Eschenbach A while back, folks noticed that a couple of months after the El Nino kicked in across the Pacific, the earth would warm up a bit. Since then, people have engaged in what they describe as “removing the El Nino signal” from the global temperature record. A while back I…

Tropical Evaporative Cooling

Guest Post by Willis Eschenbach I’ve been looking again into the satellite rainfall measurements from the Tropical Rainfall Measurement Mission (TRMM). I discussed my first look at this rainfall data in a post called Cooling and Warming, Clouds and Thunderstorms. There I showed that the cooling from thunderstorm-driven evaporation is a major heat-regulating mechanism in…
