February 2017 Second Warmest on Record —NOAA

It was the 41st consecutive February and the 386th consecutive month with temperatures exceeding the 20th century average.

The combined average temperature over global land and ocean surfaces for February 2017 was 0.98°C (1.76°F) above the 20th century average of 12.1°C (53.9°F)—the second highest for February in the 138-year period of record, trailing behind the record set in 2016 (+1.20°C / +2.16°F) and ahead of 2015 by +0.10°C (+0.18°F).

February 2017 was the highest monthly temperature departure from average since April 2016 (+1.07°C / +1.93°F) and the seventh highest monthly temperature departure among all months (1646) on record. This was the 41st consecutive February and the 386th consecutive month with temperatures above the 20th century average. The February global land and ocean temperature has increased at an average rate of +0.07°C (+0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1980.

 

The average global temperature across land surfaces was 1.78°C (3.20°F) above the 20th century average of 3.2°C (37.8°F) and the second highest February global land temperature on record, trailing behind 2016 by 0.50°C (0.90°F) and ahead of 2015 by 0.09°C (0.16°F).

This was also the highest monthly temperature departure from average since April 2016 (+1.86°C / +3.35°F) and the seventh highest among all months on record.

For the oceans, the February globally-averaged sea surface temperature was 0.69°C (1.24°F) above the 20th century average of 15.9°C (60.6°F), the second highest for February on record, behind the record-breaking year 2016 (+0.80°C / +1.44°F) and surpassing 2015 by +0.08°C (+0.14°F). February 2017 was the highest monthly temperature departure from average since October 2016 (+0.72°C / +1.30°F) and the 22nd highest among all months on record.

The average global sea surface temperature for the year-to-date was also the second highest in the 137-year record, at 0.67°C (1.21°F) above average, behind 2016 by 0.16°C (0.29°F).

The December–February seasonal global land and ocean temperature was 0.89°C (1.60°F) above the 20th century average of 12.1°C (53.8°F)—the second highest temperature departure from average for December–February in the 1880–2017 record, behind 2015/2016 by 0.23°C (0.41°F).

This was the highest three-month temperature departure since July–September 2016 (+0.89°C / +1.60°F) and tied with May–July 2016, June–August 2016, and July–September 2016 as the tenth highest three-month temperature departure from average since 1880.

The global land and ocean temperature during the three-month period of December–February has increased at an average rate of +0.07°C (+0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1980.

The globally-averaged temperature across land surfaces for December–February was also the second highest on record for the season, at 1.52°C (2.74°F) above the 20th century average of 3.2°C (37.8°F), behind 2015/2016 by 0.39°C (0.70°F).

This was the highest three-month temperature departure from average since March–May 2016 (1.81°C / 3.26°F) and the eighth highest in the 138-year record.

Across the world’s oceans, the December–February average sea surface temperature was 0.66°C (1.19°F) above the 20th century average of 15.8°C (60.5°F)—the second highest for December–February on record, trailing 2015/2016 by 0.17°C (0.31°F).

June 2014 average land and ocean temperature highest for the month since records began in 1880

The combined global average temperature across land and ocean for June 2014 was the highest for the month, at 0.72°C (1.30°F) above the 20th century average. The previous record was set in June 1998, by 0.03°C (0.05°F), according to the State of Climate Report released by NOAA.

Nine of the ten warmest Junes on record have occurred during the 21st century, including five consecutively since 2010.

“June 2014 also marks the second consecutive month with record high global temperatures. With the exception of February (21st warmest), every month to date in 2014 has ranked among the four warmest for its respective month.”

June 2014 also marked the 38th consecutive June and 352nd consecutive month with a global temperature above the 20th century average.

Selected highlights mirrored from NOAA’s June 2014 State of Climate Report:

  • The combined average temperature over global land and ocean surfaces for June 2014 was the highest on record for the month, at 0.72°C (1.30°F) above the 20th century average of 15.5°C (59.9°F).
  • The global land surface temperature was 0.95°C (1.71°F) above the 20th century average of 13.3°C (55.9°F), the seventh highest for June on record.
  • For the ocean, the June global sea surface temperature was 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F), the highest for June on record and the highest departure from average for any month.
  • The combined global land and ocean average surface temperature for the January–June period (year-to-date) was 0.67°C (1.21°F) above the 20th century average of 13.5°C (56.3°F), tying with 2002 as the third warmest such period on record.

The Ocean

The June global ocean surface temperature was record high, at 0.64°C (1.15°F) above the 20th century average of 16.4°C (61.5°F). “This marks the first time that the monthly global ocean temperature anomaly was higher than 0.60°C (1.08°F) and surpasses the previous all-time record for any month by 0.05°C (0.09°F); the previous record of +0.59°C (1.06°F) was first set in June 1998 and tied in October 2003, July 2009, and just last month in May 2014.”
