July checks in as 4th warmest on record

NASA is aggressive in filling those gaps in data, whereas scientists in Japan and the United Kingdom are more conservative, each one reaching different results for global average temperatures for a given month, Arndt said. “There are four unique approaches to try to measure a really complex thing,” Arndt said. “In the long run we do see month-to-month differences.

New US National Climatic Data Center data show that last month was the fourth-warmest July on record worldwide, even though two giant cool spots in the Northern Hemisphere – one over Siberia and the other over the US Midwest – made it easy for people living there to think that summer 2014 has been a mild one.

Sea surface temperatures last month were about 1°F above the 20th century average, tying 2009 as the warmest July on record.

NCDC data show that July 2014 was the 38th consecutive July and 353rd consecutive month with a global average temperature above the 20th century average.

The combined average temperature over land and ocean surfaces last month was 0. 67 degrees Celsius above the 20th century average of 15. 75 degrees, NCDC data show.

Other agencies in the US, Japan and Europe that calculate global average temperatures have wildly different results for last month’s ranking of the warmest Julys on record.
