For the first time, scientists have used artificial intelligence not only to predict sunspots but also to correct the incomplete record of past sunspot activity.

Study Proposes Orbital Ceres Colony
Guest essay by Eric Worrall Ceres, once considered an Asteroid but now classified as a dwarf planet orbiting between Mars and Jupiter, may harbour a significant under surface liquid water…
500 Years of Global SST Variations from a 1D Forcing-Feedback Model
If nothing else, the results in Fig. 3 might give us some idea of the ENSO-related SST variations for 300-400 years before anthropogenic forcings became significant, and how those variations…
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…
AI could deceive us as much as the human eye does in the search for extraterrestrials
FECYT – Spanish Foundation for Science and Technology An artificial neural network has identified a square structure within a triangular one in a crater on the dwarf planet Ceres, with…
Climate sensitivity in light of the latest energy imbalance evidence
Reposted from Dr. Judith Curry’s Climate Etc. Posted on January 10, 2020 by curryja | by Frank Bosse Equilibrium climate sensitivity computed from the latest energy imbalance data. The Earth…
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…
Calibrating the CERES Image of the Earth’s Radiant Emission to Space
By Philip Mulholland 1. Introduction. The following image shows the Earth’s outgoing longwave radiation recorded by the CERES (Clouds and the Earth’s Radiant Energy System) Instrument onboard the NASA Aqua…
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,…
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…
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…
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…
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…
Cooling and Warming, Clouds and Thunderstorms
Guest Post by Willis Eschenbach Following up on a suggestion made to me by one of my long-time scientific heroes, Dr. Fred Singer, I’ve been looking at the rainfall dataset…
Climate Insensitivity
Guest Post by Willis Eschenbach I’ve been wanting to [take] another look at the relationship between net top-of-atmosphere (TOA) radiation changes on the one hand and changes in temperature on…
Temperature and TOA Forcing
Guest Post by Willis Eschenbach I’ve been thinking about temperature and top-of-atmosphere (TOA) forcing. TOA forcing is the imbalance between the TOA upwelling and downwelling radiation. The CERES satellite dataset…
The Desert Finder
Guest Post by Willis Eschenbach Despite doing lots of research and investigations over the last few weeks, I’ve written little. Well, actually, I’ve published little, although I’ve written a lot.…
The CERES Calculated Surface Datasets
Guest Post by Willis Eschenbach The CERES dataset is satellite data that is based on radiation measurements made from low earth orbit. The CERES data has two parts. The first…
Arctic Albedo Variations
Guest Post by Willis Eschenbach Anthony has just posted the results from a “Press Session” at the AGU conference. In it the authors make two claims of interest. The first…
Argo And Ocean Heat Content
Guest Post by Willis Eschenbach Today I ran across an interesting presentation from 2013 regarding the Argo floats. These are a large number of independent floats spread all across the world…
Changes in Total Solar Irradiance
Total solar irradiance, also called “TSI”, is the total amount of energy coming from the sun at all frequencies. It is measured in watts per square metre (W/m2). Lots of…
Marginal Parasitic Loss Rates
Guest Post by Willis Eschenbach There is a more global restatement of Murphy’s Law which says “Nature always sides with the hidden flaw”. Parasitic losses are an example of that…
Water Vapor Feedback
Guest Post by Willis Eschenbach Well, another productive ramble through the CERES dataset, which never ceases to surprise me. This time my eye was caught by a press release about…
Three Clocks
Guest Post by Willis Eschenbach I got to wandering through the three main datasets that make up the overall CERES data, and I noticed an odd thing. The three main…
