Declining polar sea ice due to record heat

The extent of Arctic and Antarctic sea ice hit a record low in July 2019. This occurred in the month that was also the hottest ever July on record since meteorological records were begun in 1880, the US National Oceanic and Atmospheric Administration has announced.

According to NOAA measurements, July’s average temperature exceeded the previous record average July temperature measured in 2016 by 0.03 degrees Celsius. July 2019 was 0.95 degrees Celsius warmer than the average July temperature of the 20th century.

According to the report published on the NOAA website,

the extent of Arctic sea ice was at a record low, it was 19.8 percent smaller than the previous average sea ice coverage for July.

Antarctic sea ice was also 4.3 percent smaller than the average for the period 1981–2010.

The report also warned that nine of the ten hottest Julys were recorded since 2005, and the five hottest Julys were in fact those of the last five years. July 2019 was the 43rd consecutive July and the 415th consecutive month in which the average temperature exceeded the global average.

The NOAA data concur with the July data measured by the EU’s Copernicus Climate Change Service.
