Antarctica Melts Under Its Hottest Days on Record

Ice caps and glaciers felt the heat as temperatures reached 18.3°C (64.9°F).

Pine Island Glacier’s Newest Iceberg

Iceberg B-49 calved from the Antarctic glacier in February 2020.

Thwaites Glacier Transformed

The amount of ice flowing from the Antarctic glacier has doubled in the span of three decades, and scientists think it could undergo even more dramatic changes in the near future.

Arctic Ice Melt Is Changing Ocean Currents

Using 12 years of satellite data, NASA scientists have measured how the influx of cold, fresh water is affecting the Beaufort Gyre, a major Arctic current.

Widespread Melt on the George VI Ice Shelf

In January 2020, a vast area of melt formed on the surface of the ice shelf west of the Antarctic Peninsula.

NASA Airborne Campaign Catches the Drift of Snow Water

Snow is a vital source of water for drinking, agriculture and electrical power in the western United States and other locations around the world. To know how much water will be available the following spring, water resource managers and hydrologists need to know where snow has fallen, how much there is and how is characteristics change as it melts.

NASA’s Operation IceBridge Completes Eleven Years of Polar Surveys

For ten years from 2009 to 2019, the planes of NASA's Operation IceBridge flew above the Arctic and Antarctic, gathering data on the height, flow and change of sea ice, glaciers, and ice sheets.

Greenland's Rapid Melt Will Mean More Flooding

A new study finds the Greenland Ice Sheet is melting at a rate that matches the worst-case climate models, which project that flooding will affect millions of people by 2100.

Ice in Motion: Satellites Capture Decades of Change

New time-lapse videos of Earth's glaciers and ice sheets as seenfrom space, some spanning nearly 50 years, are providing new insights into howthe planet's frozen regions are changing.

NASA Highlights Solar Mission, Jupiter Cyclone at AGU Meeting

NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 9-13 in San Francisco.

Porpoiseful Ice Studies

Hundreds of scientific papers have come out of NASA’s Operation IceBridge, which ended this week.

A Transylvanian Transect for Halloween

ICESat-2 collected some perspective on the legendary landscape of Vlad and Dracula.

Is HPS-12 the Fastest Thinning Glacier?

A glacier in Patagonia with a forgettable name is becoming memorable for the speed at which it is losing ice.

Assateague on the Move

Assateague, Chincoteague, and Wallops provide a rare example of overlapping barrier islands. All of them are constantly in motion.

Rifting and Calving on the Amery Ice Shelf

The ice shelf in East Antarctica has spawned its first major iceberg in more than half a century.

Laser Precision: NASA Flights, Satellite Align Over Sea Ice

IceBridge timed flights to coincide exactly with ICESat-2 orbiting over moving Arctic sea ice - a tricky feat that paid off in demonstrating the precision of the new satellite.

Edge of the Ice

Summer snowmelt along the flank of Greenland’s Humboldt Glacier exposes layers of ice from ancient climate periods.

Malaspina on the Move

More than 30 years of ice velocity data are helping scientists tease out how mountain glaciers respond to climate change.

Landsat Illustrates Five Decades of Change to Greenland Glaciers

Greenland's Helheim Glacier, along with its neighbors, have changed significantly in the last five decades, as illustrated by comparing Landsat images from 1972 and 2019.

Okjökull Remembered

The glacier atop Iceland’s Ok volcano was declared dead in 2014. Satellite images show the latter stages of its decline.

Warm Weather Brings Major Melting to Greenland

Melting was provoked by a bubble of warm air that moved over Greenland after delivering unseasonably warm temperatures to Europe.

The Ups and Downs of Crater Lake

Elevation data show the distinct topography of Mount Mazama and the crater lake that fills its caldera.

Brunt Ice Shelf Survives the Solstice

The enormous slab of ice poised to break away from the Brunt ice shelf is still hanging on.

Ice Arch Crumbles Early

The structure that prevents sea ice from exiting the Arctic Ocean through the Nares Strait crumbled months earlier than usual.

Study Predicts More Long-Term Sea Level Rise from Greenland Ice

Greenland’s melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study. The study, which used data from NASA’s Operation IceBridge airborne campaign, was published in Science Advances today.
