It’s cold in New York today: -7 C (19 F), the coldest it’s been in two years. This is good because I am writing about cold things. Not surprisingly, January 22 has a cold history: 1930: -37 C (-35 F), Mount Carroll, Illinois (State record)
1982: 75% of the United States is covered in snow. 1985: -34 C (-30 F), Mountain Lake Bio Station, Virginia (State record); also 90% of the citrus crop is damaged by a cold wave in Florida.
