June 2019 was the hottest June recorded in the 140 years since the US National Oceanic and Atmospheric Administration (NOAA) began collecting global temperature data, the agency announced yesterday.

On land, June’s global average surface temperature was 2.41 degrees Fahrenheit above the 20th-century average of 55.9°F, the highest June land temperature on record, beating the previous record set in 2015. At sea, average surface temperatures were 1.46 degrees Fahrenheit above the 20th-century monthly average of 61.5 degrees Fahrenheit, tying June 2016 as the highest global average ocean temperature on record for June.

2019 also saw the second-smallest Arctic sea ice extent for the month of June in the 41-year record, according to an analysis of NOAA and NASA data by the National Snow and Ice Data Center. For the fourth consecutive June, Antarctic sea ice extent was also lower than average, reaching a mark 425,000 square miles, or 8.5 percent, below the 1981-2010 average.

June 2019 was the hottest June recorded in the 140 years since the US National Oceanic and Atmospheric Administration (NOAA) began collecting global temperature data, the agency announced yesterday.

Global land and ocean surface temperatures were 1.71 degrees Fahrenheit above the 20th-century average of 59.9 degrees Fahrenheit last month, “the highest for June in the 1880-2019 record,” NOAA reported. The month was 0.04 degrees Fahrenheit hotter than the previous record, set in 2016.

That makes June 2019 the 43rd consecutive June and the 414th consecutive month with temperatures above the 20th-century average. Year to date, 2019 has been the second warmest January-June ever recorded.

According to NOAA data, the biggest departures from average temperatures in June 2019 occurred in central and eastern Europe, north-central Russia, northeastern Canada, and southern parts of South America, where temperatures were 3.6 degrees Fahrenheit above the 1981-2010 average or higher. Many of those same regions, as well as parts of Asia, Africa, and the Atlantic, Indian, and Pacific oceans, experienced record warm temperatures. No land or ocean areas experienced record cold temperatures in June.

The most notable cooler-than-average temperatures were found in parts of western Asia and Antarctica, where temperatures were at least 1.8 degrees Fahrenheit below the 1981-2010 average.

On land, June’s global average surface temperature was 2.41 degrees Fahrenheit above the 20th-century average of 55.9°F, the highest June land temperature on record, beating the previous record set in 2015. At sea, average surface temperatures were 1.46 degrees Fahrenheit above the 20th-century monthly average of 61.5 degrees Fahrenheit, tying June 2016 as the highest global average ocean temperature on record for June. The 10 months with the biggest departures from average global ocean monthly temperatures have all occurred since September 2015.

2019 also saw the second-smallest Arctic sea ice extent for the month of June in the 41-year record, according to an analysis of NOAA and NASA data by the National Snow and Ice Data Center. At 475,000 square miles, or 10.5 percent, below the 1981-2010 average, June 2019 was the 20th consecutive June with Arctic sea ice extent below average.

For the fourth consecutive June, Antarctic sea ice extent was also lower than average, reaching a mark 425,000 square miles, or 8.5 percent, below the 1981-2010 average. That’s the smallest June extent for Antarctic sea ice in the 41-year record, surpassing the previous record, set in 2002, by 62,000 square miles.

Nine of the 10 warmest Junes have occurred since 2010. June 1998 is the only entry on the list of the 10 warmest Junes on record that occurred in the previous century.
