Should I buy property in Greenland or more winter clothes? LOL

I would like to see the graphs going back to the 1920s. I doubt data is available to back then, however.

Interested folks have been counting Sun Spots for a long time.

It's gonna get cold.



We are currently less than half the value shown in this chart as 'projected' for cycle 24. If this chart were updated for the actual cycle 24 data it would be the smallest peak in the chart.

Sunspots have been tracked for about 400 years or so. The use of sunspots to predict weather was used by Ben Franklin in his farmers almanac. I do not know haw long before that.
