Last year, we set a record for sunspots that was last equaled in 1913. Sunspots are a good visual proxy for solar activity and the more of them, the hotter the sun and the warmer the Earth. This bears out as the Modern Warm Period started around 1914 or so. It peaked in the 1970's and Earth starting to really cool off now.
Last year, 77% of the days had no sunspots. Today, 2020 just hit the very same number. We had a flurry of spots at the beginning of the year but there have been very few since. Today, we tie the 2019 and the 1913 records.
