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…

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…
