The average global temperature in June was 1.71 degrees F above the 20th-century average of 59.9 degrees (15.5 °C), making it the hottest June in the 140-year record, according scientists from the US National Oceanic and Atmospheric Administration.
Namely, data provided by NOAA’s National Centers for Environmental Information indicate that nine of the 10 hottest Junes have occurred since 2010.
Last month also was the 43rd consecutive June and 414th consecutive month with above-average global temperatures.
Meanwhile, for the second month in a row, warmth brought Antarctic sea-ice coverage to a new low for June.

The period from January through June produced a global temperature 1.71 degrees F above the 20th-century average of 56.3 (13.5°C) degrees, tying with 2017, as the second-hottest year to date on record.
It was the hottest first half of the year for: South America, parts of the southern portion of Africa, Madagascar, New Zealand, Alaska, western Canada, Mexico, eastern Asia, the Atlantic and Indian oceans, and the Bering Sea.
Additionally, average Antarctic sea-ice coverage was 8.5% below the 1981-2010 average – the smallest on record for June.
Average Arctic sea ice coverage was 10.5% below average – the second-smallest on record for June.
However, the contiguous US and southern Canada had year-to-date temperatures at least 1.8 degrees F cooler than average.
