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.

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.

NASA Explores Our Changing Freshwater World

Water is so commonplace that we often take it for granted. But too much – or too little of it – makes headlines.

First ICESat-2 Global Data Released: Ice, Forests and More

ICESat-2 data is available to the public to investigate questions related to Earth.

NASA’s Goddard Space Flight Center Celebrates 60 Years

On May 1, 1959, the Beltsville Space Center in Greenbelt, Maryland, was renamed NASA’s Goddard Space Flight Center in honor of Robert H. Goddard, widely considered the father of modern rocketry. Thus began a 60-year boom in science and technological innovation.

Greenland Refrozen

Most indications of meltwater ponds and lakes on the ice sheet are leftovers from past seasons that have since refrozen.

NASA Celebrates Earth Day with Social Media, Public Events

This Earth Day, April 22, NASA invites you to celebrate our beautiful home planet by participating in a global social media event and local events around the country.

Warm Winds Trigger Melting in Antarctica

Unusual late-season events could produce long-term changes to the snowpack on the Larsen C ice shelf.

Picture Earth for Earth Day 2019

For Earth Day 2019, NASA invites you to celebrate the planet we call home with our #PictureEarth social media event.

The Wide View of a Shrinking Glacier: Retreat at Pine Island

Pine Island Glacier is one of the fastest-retreating glaciers in Antarctica. This timeline highlights the most notable calving events of the past two decades.

NASA Begins Final Year of Airborne Polar Ice Mission

This is the last year for Operation IceBridge, NASA’s most comprehensive airborne survey of ice change.

Operation IceBridge: Exploring Alaska’s Mountain Glaciers

In Alaska, 5 percent of the land is covered by glaciers that are losing a lot of ice and contributing to sea level rise.

A Decade of Exploring Alaska’s Mountain Glaciers

In Alaska, five percent of the land is covered by glaciers that are contributing to sea level rise in ways disproportionately large to their size. A small airborne campaign has been monitoring these changes since 2009.

Help NASA Measure Trees with Your Smartphone

A new smartphone-based project allows people to document the trees around them in order to learn more about their environment and provide valuable data to NASA scientists who study our home planet.

Arctic Sea Ice 2019 Wintertime Extent Is Seventh Lowest

The 2019 Arctic sea ice maximum extent ties with 2007's for seventh lowest in the satellite record, continuing the long-term decline of the Arctic sea ice pack.

Decoding Extreme Weather at the Poles

A silvery metal tube jutting out of thick ice stands alone amid a vast landscape of endless white in Antarctica.

NASA Invites Media to 57th Annual Robert H. Goddard Memorial Symposium

Media are invited to the 57th Robert H. Goddard Memorial Symposium on March 20-21.

Countdown to Calving at Brunt Ice Shelf

Cracks growing across the ice shelf are poised to release an iceberg about twice size of New York City.

New NASA Book Shares Beauty of Earth from Space

NASA’s new 168-page book “Earth,” a collection of dramatic images captured by Earth-observing satellites, is available now in hardcover and ebook, and online with interactive features.

NASA Finds Possible Second Impact Crater Under Greenland Ice

A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland.

ICESat-2 Sees the Trees in Mexico

The satellite measures more than just polar ice; it also makes detailed elevation measurements over the planet’s tropical and temperate latitudes.

Thick and Thin Ice in the Weddell Sea

New elevation measurements will give researchers an unprecedented understanding of the thickness of sea ice, which will be used to help improve climate modeling and forecasts.

Snow over Antarctica Buffered Sea Level Rise during Last Century

A new NASA-led study has determined that an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches.
