Did it feel unusually warm last month? The whole world did, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). July 2019 was the warmest month in the 140-year NOAA global temperature dataset, which dates back to 1880.

The July 2019 temperature across global land and ocean surfaces was 1.7° F above the 20th century average of 60.4° F. The most marked warm temperature departures from average were experienced across Alaska, central Europe, northern and southwestern parts of Asia, and parts of Africa and Australia, where temperatures were at least 2.7° F above the 1981–2010 average or higher.

Warming trends are also reflected in declining polar ice coverage. A record low in Arctic sea ice extent for July was documented at 726,000 square miles (19.8%), below the 1981–2010 average and 30,900 square miles below the now second-lowest July sea ice extent set in 2012. Sea ice loss occurred at an average rate of 40,800 square miles per day in July 2019, surpassing the 1981–2010 average of 33,500 square miles. The July 2019 Antarctic sea ice extent was 260,000 square miles (4.3%), below the 1981–2010 average and was the smallest July extent in the 41-year record.
