This is different chart. For some reason my usual plot from Spencer is not ready. They must have killed him. :) This is the same chart, brightness from the surface. The big drop of El Nino, then the scary rise (scary for me) in December, and now a good drop for January. Like the Toronto housing market, I expect this curve to sink to new lows.
Note that all the news says "Lowest temperature in 20 years!". Wonder why?
Gotta love the British!
If they only knew.....
