greenhouse
The National Oceanic and Atmospheric Administration(NOAA) reports the July 2015 average temperature across global land and ocean surfaces was 1.46°F (0.81°C) above the 20th century average, making it the all-time highest monthly temperature in the 1880–2015 record, at 61.86°F (16.61°C), surpassing the previous record set in 1998 by 0.14°F (0.08°C).

The July globally-averaged sea surface temperature was 1.35°F (0.75°C) above the 20th century average, also the highest temperature for any month in the 1880–2015 record, surpassing the previous record set in July 2014 by 0.13°F (0.07°C). Global oceans at the surface also registered record warmth for July, and the January-July 2015 also recorded warm temperatures.

The average Arctic sea ice extent for July was 350,000 square miles (9.5 percent) below the 1981–2010 average. This was the eighth smallest July extent since records began in 1979 and largest since 2009, according to analysis by the National Snow and Ice Data Center using data from NOAA and NASA.

Antarctic sea ice during July was 240,000 square miles (3.8 percent) above the 1981–2010 average. This was the fourth largest July Antarctic sea ice extent on record and 140,000 square miles smaller than the record-large July extent of 2014.
Global highlights: Year-to-date (January–July 2015)

The year-to-date temperature combined across global land and ocean surfaces was 1.53°F (0.85°C) above the 20th century average. This was the highest for January–July in the 1880–2015 record, surpassing the previous record set in 2010 by 0.16°F (0.09°C).

The year-to-date globally-averaged land surface temperature was 2.41°F (1.34°C) above the 20th century average. This was the highest for January–July in the 1880–2015 record, surpassing the previous record of 2007 by 0.27°F (0.15°C).

The year-to-date globally-averaged sea surface temperature was 1.21°F (0.67°C) above the 20th century average. This was also the highest for January–July in the 1880–2015 record, surpassing the previous record of 2010 by 0.11°F (0.06°C). Every major ocean basin observed record warmth in some areas.
