The Arctic is just as warm today as it was yesterday, +3.5C above the 1990-2000 baseline average.  (Add about one degree for a late 19th century baseline.)  I’ll be showing the relevant maps below, with a few comments, but first, … Continue reading →

Another big day for Arctic warming—up 3.5C in just over three decades—and more than six times the global trendline increase for the same period (0.55C). The map shows us one spot quite close to the North Pole that has an … Continue reading →

When we open the anomaly map today we see the Arctic up 3.1C from the baseline average—over five times greater than the global trendline number of 0.55C. One quick glance tells us that areas of warm anomaly inside the Arctic … Continue reading →

A new way of measuring the thickness of Arctic sea ice enhances predictions of further rapid decline.  This was the conclusion reported in a study released on March 10 and reviewed by Phys.org::  https://phys.org/news/2022-03-icesat-remarkable-arctic-sea-ice.html.  The thickest ice, which is the … Continue reading →

Weekend letters are being issued mainly for the purpose of daily archiving of images. Comments are added when something of keen interest appears—like we will be seeing today. Look closely at the bright red area of anomaly extending from northeast … Continue reading →

Today’s anomaly map.  During the past week the world, tropics and NH have all experienced short-term  cooling trends, the SH has been flat, and both polar regions have been warming.  The Arctic today is very close to being on the … Continue reading →

This is a followup on the ideas presented in yesterday’s letter. We are focused on why the “blue zone” on the high-altitude air pressure map is structured as we see it each day. This is interesting because of real-world implications—a … Continue reading →

Yesterday’s letter described the processes behind the formation of hot and cold temperature anomalies on a daily basis. These anomalies have more volatility in the Arctic than anywhere else on the globe. They are created by the highly irregular distribution … Continue reading →

Every day we have been looking at peculiar mixtures of hot and cold temperature anomalies over North America. Every following day there is a whole new set of anomalies, many of them tied to new locations. The ratio of hot … Continue reading →

We are embarked on a daily analysis of why the Arctic is warming much faster than the rest of the world—about four times as fast according to a recent study in Nature.  Our baseline period, 1979-2000, is fairly short, making … Continue reading →
