Steve Goddard reminded me that weve had 220 Years of Global Warming in Philadelphia.
Starting in 1790, a prominent Philadelphia resident named Charles Pierce started keeping detailed records of the weather and climate, which has been archived on Google Books.
His report from January, 1790 is below:
JANUARY. 1790. The average or medium temperature of this month was 44 degrees. This is the mildest month of January on record. Fogs prevailed very much in the morning, but a hot sun soon dispersed them, and the mercury often ran up to 70 in the shade, at mid-day. Boys were often seen swimming in the Delaware and Schuylkill rivers. There were frequent showers as in April, some of which were accompanied by thunder and lightning. The uncommon mildness of the weather continued until the 7th of February.
Compare vs. January, 2010 which had a mean temperature of 32 degrees 12 degrees cooler than 220 years ago. So far, February is even colder.
