Disclaimer. After nearly 40 years managing money for some of the largest life offices and investment managers in the world, I think I have something to offer. These days I'm retired, and I can't by law give you advice. While I do make mistakes, I try hard to do my analysis thoroughly, and to make sure my data are correct (old habits die hard!) Also, don't ask me why I called it "Volewica". It's too late, now.

BTW, clicking on most charts will produce the original-sized, i.e., bigger version.

Massive Arctic temperature uptrend

The Arctic winter has become 5 degrees warmer in just 30 years.  5 degrees!  (the chart shows the actual temperature; the map shows the anomaly from the 1981 -2000 average)
