NOAA and NASA Global Temperature Analyses — June 2016

Greetings Climate Matters Meteorologists!

NASA and NOAA released their global temperature analyses for June this morning. While each agency uses a slightly different method to calculate the average monthly temperature for the globe, both analyses indicate that January to June 2016 was hottest first half of a calendar year on record globally.

Listen to the NASA press conference on the temperature analysis at 1pm ET here.

Some statistics from NOAA:

• June 2016 was the 14th consecutive month of record heat for the globe.

• The June temperature across global land and ocean surfaces was 1.62°F (0.90°C) above the 20th century average of 59.9°F (15.5°C). This was the highest for June in the 1880–2016 record.

• The average Arctic sea ice extent for June was 530,000 square miles (1.37 million square kilometers) below average, which is roughly twice the area of Texas. This is 11.4% below the 1981–2010 average and was the smallest June extent since satellite records began in 1979.

• The year-to-date temperature across global land and ocean surfaces was 1.89°F (1.05°C) above the 20th century average of 56.3°F (13.5°C) . This was the highest for January-June in the 1880–2016 record.

As a reminder, the NOAA anomalies are calculated from a 20th century baseline. As the global conversation focuses on a goal of limiting warming to 2°C above pre-industrial levels, we have combined the NOAA and NASA global temperature numbers and adjusted them to an early industrial baseline of 1881-1910 to better gauge our warming against this global goal. This is reflected in the enclosed graphic.
