NOAA released its monthly global temperature analysis for January 2017 this morning. Over land and ocean surfaces combined, it was the 3rd hottest January on record. Records go back to 1880. Some highlights:
• This January was 0.88°C (1.58°F) above the 20th century average. The only two Januaries that were hotter were in 2016 and 2007.
• The 9 hottest Januaries have all come in the 21st century. In 10th place was 1998.
• The last January below the 20th century average was in 1976.
• The January globally averaged ocean temperature was the 2nd hottest on record, even above the El Niño events in 1983 and 1998.
• The January globally averaged temperature over land was the 3rd hottest on record, 1.54°C (2.77°F) above the 20th century average.
Today's NOAA calculations resemble the analysis released by NASA earlier this week, also indicating that last month was the 3rd hottest January on record globally.
