Toasty Tuesday (and August)

Summer just won’t let go.  With a ridge of high pressure in place this week, temperatures will remain near 90 degrees each day with very little chance of rain. The saving grace will be that the dew points will remain low, so it will be hot, but not hot and excessively humid. For allergy suffers, ragweed is still an issue.  The pollen count remain in the moderate category at 8.7 tomorrow.


Toasty is the key word in today’s blog as I share the findings of NOAA’s monthly global temperature analysis for August 2016. Not only was this August the hottest on record, it is the 16th consecutive month that the Earth recorded record warm temperatures. This is the longest streak of it’s kind since NOAA started keeping records in 1880.


If this sounds familiar that’s because I also reported that NASA reached the same conclusion that August 2016 was the hottest on record. NASA’s records also go back to the 1800s. They indicated that August tied with July as globally the hottest month on record. On the graphic below, each line represents the yearly temperature anomaly, broken down by each month of the year, and measured against as 1980-2015 baseline. August 2016 is at the peak of the top curve on the graphic.


Climate Central puts together great graphics to illustrate the findings.  The NOAA anomalies are calculated from a baseline of a 20th century average. To better represent how much the temperature has changed since the early industrial area, Climate Central combines the NOAA and NASA global temperature data and adjusts them to a baseline of 1881-1910. This is reflected in the graphic below.


If you want to look at more specific numbers, Climate Central provides more facts and figures…

  • The August 2016 combined average temperature over global land and ocean surfaces was 1.66°F (0.92°C) above the 20th century average.

  • 14 of the 15 highest monthly land and ocean temperature departures on record have occurred since February 2015.

  • The June-August (meteorological summer in the Northern Hemisphere) combined average temperature over global land and ocean surfaces was the hottest on record, at 1.60°F (0.89°C) above the 20th century average. This surpasses the previous record from 2015.

Global year-to-date temperatures through August:

  • The temperature across global land and ocean surfaces was the hottest on record, at 1.82°F (1.01°C) above the 20th century average of 57.3°F (14.0°C).

  • The average global sea surface temperature was the hottest on record, at 1.42°F (0.79°C) above average, surpassing the previous record set in 2015.

Thanks to my friends at Climate Central for their assistance with this information.
