Following on the heels of the hottest May in global history, the subsequent month has now been confirmed as the hottest June on record.
According to the National Ocean and Atmospheric Administration (NOAA), combined average temperatures for land and ocean surfaces for June 2014 were the highest on record since global measurements began in 1880. This was mostly due to rising ocean temperatures (particularly the Pacific and Indian oceans), which were 1.15°F above the 20th century average of 61.5°F.
“We are living in the steroid era of the climate system,” said NOAA climate monitoring chief Derek Arndt.
In its monthly climate report, NOAA states that nine of the ten warmest Junes have all occurred in the 21st century. Even more alarming, every month of 2014 (with the exception of February) has ranked among the four warmest ever recorded.
“This is what global warming looks like,” climate scientist Jonathan Overpeck wrote the Guardian in an email. “Not record hot everywhere all the time, but certainly a reflection that the odds of record hot are going up everywhere around the planet.”
The “hottest June” classification is derived from a global average, as not all countries experienced record high temperatures. June 2014 ranks as only the 33rd hottest for the United States, and its sixth wettest since 1895. Not so for New Zealand, Central Africa, France and the UK, which were scorched last month. In addition, heat records were set in South America, Greenland, central Africa and southern Asia.
