June was the hottest June on record for the planet and marked the third month of the year that's been record warm globally. The globally averaged temperature over land and ocean surfaces for June 2015 was the highest for the month of June since record-keeping began in 1880. The past month was 1.39°F above the 20th century average of 53.6°F.
The data in the charts above just at a quick glance speak volumes. You can't deny the data that shows warming and at a rapid rate.
Record warmth was seen in June in the western U.S., parts of northern South America, several regions in central to western Africa, central Asia, and parts of southeastern Asia, the centers reported.
The U.S., overall, had its second-warmest June on record. Only June 1933 was hotter. Five western states — California, Oregon, Washington, Idaho, and Utah — were all record warm.
The record warmth is due in part to El Nino, which is a climate pattern marked by warmer-than-average water in the tropical Pacific Ocean. The heat from the warm water helps boost temperatures in the atmosphere around the world.
While El Nino is a part of the warmth, the long-term trend of man-made climate change is also a contributor: NOAA reports that 14 of the 15 warmest years on record have occurred since 2000, many during years without the boost of an El Nino.
How global temperatures shape up over the rest of the year remains to be seen, but the ocean tends to hang on to heat for much longer than land areas, which will keep temperatures elevated for a while. And as carbon dioxide and other greenhouse gases continue to be emitted, it will likely result in warmer and warmer years in the future.
