The Arctic experienced its warmest summer on record in 2023, with an average temperature of 6.4 degrees Celsius (43 degrees Fahrenheit), the highest since records began in 1900, according to the National Oceanic and Atmospheric Administration's (NOAA) 2023 Arctic Report Card released Tuesday.

The annual Arctic Report Card, now in its 18th year, is the work of 82 authors from 13 countries.

Overall, it was the Arctic's sixth warmest year, at -7 degrees Celsius (20 degrees Fahrenheit).

Data reveals that since 1940, the annual average temperatures have increased 0.25 degrees Celsius (0.45 degrees Fahrenheit) per decade and average summer temperatures have risen 0.17 degrees Celsius (0.31 degrees Fahrenheit) per decade.

The report also specifies that “sea ice extent continues to decline.”

Sea ice extent continues to decline, with the 17 lowest Arctic sea ice extents on record occurring during the last 17 years. This year’s sea ice extent was the sixth lowest in the satellite record, which began in 1979, with older, thicker multi-year ice far less than in the 1980s, according to the NOAA Arctic Report Card 2023.
