The Arctic experienced its warmest summer on record.

On December 12, the US National Oceanic and Atmospheric Administration (NOAA) released a report showing that the surface air temperature in the Arctic in the summer of 2023 reached its highest level ever.

In its annual Arctic climate assessment report, NOAA said the average temperature in the Arctic from July to September this year was 6.4 degrees Celsius, the highest level since such data began to be collected in 1900.

Average summer temperatures in the Arctic have increased by 0.17 degrees Celsius per decade. Overall, 2023 was the sixth warmest year on record for the region.

Sea ice extent also continued to decline, with Septembers of the past 17 years seeing record low sea ice extent.

The NOAA report cited data on record increases in average global ocean and land surface temperatures in 2023, saying the main cause was the impact of human activities.

Rising global temperatures are affecting ecosystems and human communities across the Arctic, making the region warmer, less icy, and more prone to extreme weather events, according to NOAA.

The US meteorological agency said that the number of Western Alaska salmon has dropped to a record low in the period 2021-2022, with the cause believed to be due to climate changes in the marine ecosystem.

This year’s Arctic climate report shows “the time to act is now,” said NOAA Administrator Rick Spinrad, adding that NOAA and its partners have stepped up support and collaboration with Arctic communities to help build climate resilience.

Mr. Spinrad also called on the international community to join hands to reduce greenhouse gas emissions - which are the cause of climate change.
