Across the globe, snow and ice play a vital role in regulating Earth’s climate and providing freshwater resources to people, plants, and animals.

As Earth’s frozen regions change rapidly, NSIDC is committed to growing its research and open access data to better understand these changes. Read about NSIDC research and its contribution to science and policy making. Check out spotlights on how to use NSIDC data, tools, and resources. Learn about how we steward data and collaborate with scientists and organizations across the world to understand how the frozen parts of Earth affect the rest of the planet and impact society.

A newly published study has mapped glacial debris across the Greater Caucasus, the mountainous region between the Black and Caspian Seas. The study found an increasing trend in glacial debris between 2014 and 2020. The authors relied on GLIMS data at NSIDC in their research.

As darkness extends southward across the Arctic, sea ice has advanced to much of the Russian shoreline, but growth has been particularly slow in the Barents and Kara Seas. In the Antarctic, with the onset of spring, the pace of seasonal sea ice loss has increased.

Since 2007, the Arctic sea ice minimum has dropped below 5 million square kilometers (1.93 million square miles) every year, except in 2009, 2013, and 2014, when extent barely crossed the 5 million square kilometer mark. Such low extents would have been hard to imagine in the 1990s, when extent averaged 6.46 million square kilometers (2.49 million square miles). Arctic climate warming continues to lead an unfortunate path of change for the planet. Here, NSIDC researchers summarize this year’s events in the Arctic, and touch upon Antarctica sea ice extent at the end of its austral winter.
This NASA Blue Marble image shows Antarctic sea ice on September 19, 2024, when sea ice reached its maximum extent for the year. Sea ice extent for September 19 averaged 17.16 million square kilometers (6.63 million square miles), the second lowest in the satellite record.
News Release
Antarctic sea ice has likely reached its maximum extent for the year, at 17.16 million square kilometers (6.63 million square miles) on September 19, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder (CU Boulder). The 2024 maximum is the second lowest in the 46-year satellite record.
