Last month was declared the hottest June in 137 years of record keeping, making it the 14th consecutive month to break the global temperature record, according to the US weathermen. Warmer to much-warmer-than-average conditions dominated across much of the globe's surface, resulting in the highest temperature departure for June since global temperature records began in 1880.
This was also the 14th consecutive month the monthly global temperature record has been broken - the longest such streak in National Oceanic and Atmospheric Administration's 137 years of record keeping.
The June 2016 combined average temperature over global land and ocean surfaces was 0.90 degrees Celsius above the 20th century average, besting the previous record set in 2015 by 0.02 degrees Celsius. June 2016 marks the 40th consecutive June with temperatures at least nominally above the 20th century average.
The last time June global land and ocean temperatures were below average was in 1976. June 2016 tied with March 2015 as the ninth highest monthly temperature departure among all months (1,638) on record.
Overall, 14 of the 15 highest monthly temperature departures in the record have all occurred since February 2015, with January 2007 among the 15 highest monthly temperature departures.
June 2016 also marks the 378th consecutive month with temperatures at least nominally above the 20th century average. The last month with temperatures below the 20th century average was December 1984. The majority of the world's land surface had warmer to much-warmer-than-average temperatures during June 2016, with the largest temperature departures observed across much of north central Russia, the Russian Far East, and northern Australia where temperature departures were 3.0 degrees Celsius or higher.
Record warmth was sporadically across parts of the southwestern contiguous US, southern Mexico, northeastern Brazil, northeastern and southwestern Africa, the Middle East, northern Australia, and Indonesia. The only land area with cooler-than-average conditions during June 2016, according to the percentiles map, was central and southern South America.
No land areas had a record cold temperature during June 2016. Five of six continents had at least a top five warm June, with North America observing a record high average temperature for June. Averaged as a whole, the global temperature across land surfaces for June 2016 was 1.24 degrees Celsius above the 20th century average - tying with 2015 as the highest June temperature in the 18802016 record.
June 2016 marks the 34th consecutive June with temperatures at least nominally above average. The last time global land surface temperatures were below average in June was in 1982.
