Globally, June was 4th warmest on record, NOAA announced today. And over the Northern Hemisphere, for the second consecutive month, temperatures were as warm as they’ve been in 133 years of records. Notably, the Arctic experienced its largest June sea ice loss since the start of satellite records in 1979.
It was the 36th consecutive June and 328th consecutive month with temperatures warmer than the 20th century average, NOAA said…
The decline of Arctic sea ice is one of the more telling indicators of recent warmth in the Northern Hemisphere. The Arctic lost the equivalent of 1.1 million square miles of ice in June (most on record), its extent falling to 9.8 percent below average, second lowest on record (since 1979).
Snow cover in the Northern Hemisphere, another indicator of temperature, reached its lowest extent in 45 years of June records."
