Warmest Arctic Summer on Record is Evidence of Accelerating Climate Change

NOAA’s 2023 Arctic Report Card documents new records showing that human-caused warming of the air, ocean and land is affecting people, ecosystems and communities across the Arctic region, which is heating up faster than any other part of the world.

NOAA’s 2023 Arctic Report Card documents new records showing that human-caused warming of the air, ocean and land is affecting people, ecosystems and communities across the Arctic region, which is heating up faster than any other part of the world.

Summer surface air temperatures during 2023 were the warmest ever observed in the Arctic, while the highest point on Greenland’s ice sheet experienced melting for only the fifth time in the 34-year record. Overall, it was the Arctic’s sixth-warmest year on record. Sea ice extent continued to decline, with the last 17 Septembers now registering as the lowest on record. These records followed two years when unprecedented high abundance of sockeye salmon in western Alaska’s Bristol Bay contrasted with record-low Chinook and chum salmon that led to fishery closures on the Yukon River and other Bering Sea tributaries.

“The overriding message from this year’s report card is that the time for action is now,” said Rick Spinrad, Ph.D., NOAA administrator. “NOAA and our federal partners have ramped up our support and collaboration with state, tribal and local communities to help build climate resilience. At the same time, we as a nation and global community must dramatically reduce greenhouse gas emissions that are driving these changes.”
