Wow, this is interesting. According to the National Oceanic and Atmospheric Administration, we’ve had 332 consecutive months of above-average temperatures (compared to the average for the 20th Century). The last month with a colder-than-normal temperature was February 1985.
So, if you are 27 or younger, you have never experienced a month that was colder than normal.
During the past year, every land mass across the globe experienced warmer-than-average temperatures except for two places–Alaska, and the eastern tip of Russia.
