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.

Record cold in Minnesota

It's very cold in Minnesota.  In fact it's record cold.  Does that mean that there's no such thing as global warming?

Well,  no.  Because that's just one part of the world.  The rest of the world (including where I live) is warmer than average, as this graphic shows:

It's the global or perhaps the regional averages which matter, and their average over time.  The chart below shows a 60 month moving average of the global average anomaly.  A 5 year average helps remove a lot of the random year-to-year variation.  Short term cycles remain.  And so does the longer term trend, which is glaringly obvious.
