Understanding Arctic Climate Trends: Insights and Tools for iPad Users
The Arctic region is experiencing unprecedented changes, with temperatures rising at more than double the global average. The 2025 Arctic Report Card highlights several key trends:
Record-Breaking Temperatures
From October 2024 through September 2025, Arctic surface air temperatures were the warmest recorded since 1900. Autumn 2024 and winter 2025 were especially warm, ranking first and second, respectively. The last decade has seen the ten warmest years on record in the Arctic. Since 2006, Arctic annual temperatures have increased at more than double the global rate. (arctic.noaa.gov)
Declining Sea Ice
In March 2025, Arctic winter sea ice reached its lowest annual maximum extent in the 47-year satellite record. September 2025 saw the tenth lowest minimum sea ice extent, with all of the 19 lowest September minimum ice extents occurring in the last 19 years. The oldest, thickest Arctic sea ice has declined by more than 95% since the 1980s. (prod-01-asg-www-climate.woc.noaa.gov)
Ocean Warming and Atlantification
In August 2025, the marginal seas of the Arctic Ocean’s Atlantic sector saw average sea surface temperatures approximately 13°F (7°C) warmer than the 1991-2020 August average. This phenomenon, known as "Atlantification," involves the influx of warmer, saltier waters from lower latitudes into the Arctic Ocean, weakening the layering of waters and enhancing heat transfer, which contributes to sea ice melting and disrupts ocean circulation patterns.

Impacts on Marine Ecosystems
From 2003 to 2025, phytoplankton productivity spiked by 80% in the Eurasian Arctic, 34% in the Barents Sea, and 27% in Hudson Bay. Plankton productivity in 2025 was higher than the 2003-2022 average in eight of nine regions assessed across the Arctic. These changes are reshaping Arctic food webs and affecting Indigenous subsistence practices. (arctic.noaa.gov)
Glacier and Ice Sheet Loss
Glaciers in Arctic Scandinavia and Svalbard experienced the largest annual net loss of ice on record between 2023 and 2024. The Greenland Ice Sheet lost an estimated 129 billion tons of ice in 2025, continuing the long-term trend of net loss. Alaskan glaciers have lost an average of 125 vertical feet (38 meters) of ice since the mid-20th century, dramatically lowering ice surfaces statewide. Ongoing glacier loss contributes to steadily rising global sea levels, threatening Arctic communities’ water supplies and increasing the risk of destructive floods, landslides, and tsunamis.

Enhanced Precipitation
Precipitation from October 2024 to September 2025 set a new record high. Arctic precipitation totals for winter, spring, and autumn were each among the top five since 1950. (arctic.noaa.gov)
