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.

Working with Indigenous communities takes time, resources, and patience, but a shift is needed in science to include community voices and observations to widen and deepen our collective breadth of knowledge. The Exchange for Local Observations and Knowledge of the Arctic (ELOKA), a NSIDC program, continues to collaborate with the Alaska Arctic Observatory and Knowledge Hub (AAOKH) to support an online community-led observational data hub.
Snow-covered area for the western United States hit another record for April, the second month in a row since the satellite record began in 2001. With longer days, more sun, and increasing temperatures in the coming months, concerns arise for how quickly the snowpack may melt in California with potential for flood risks.
Algae that commonly grow on snow in the Pacific Northwest have been ignored in melt models, but their presence significantly increases snowmelt compared with clean, white snow, according to a first-of-its-kind scientific research study conducted on Mt. Baker in the North Cascades, Washington.
NSIDC’s Nenana Ice Classic: Tanana River Ice Annual Breakup Dates data set provides a record of ice-breakup dates related to an annual contest that started in 1917 and remains a heated competition over a century later.
By Brigitta Rongstad In April 2016, a warm front approached southwest Greenland, causing air temperatures in the capital city of Nuuk and the surrounding area to increase rapidly. A cold front formed nearby and the two air masses collided, creating a
Understanding how the Greenland Ice Sheet's complex water system functions is key to estimating how much meltwater it is losing and how quickly sea levels will rise.
