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 strong weather pattern from August 21 to 24 caused widespread melting across Greenland. This unusually late summer melt event was caused by a high and low air pressure configuration known as an omega pattern because of its jet stream shape.

The ICESat-2 mission provides data sets on land ice and sea ice, and those data sets have been applied to myriad studies of Earth’s frozen regions, but ICESat-2 data offerings do not end there. Researchers can also use ICESat-2 observations to study surface-height changes in land and vegetation, inland water bodies, ocean surfaces, and atmospheric features.
Analysis - Sea Ice Today
After declining at a near-average pace for much of the summer, Arctic sea ice loss accelerated during early August.
Feature Story
In 2011, a group of scientists in southeastern Greenland discovered a massive perennial firn aquifer—a year-round, water-bearing layer within the firn. Since then, scientists have discovered more areas around the world bearing this ice feature, but questions remain to their development and impact.
