Iceberg A-68A Nears South Georgia

Scientists watch as A-68A, currently the planet’s largest iceberg, approaches a remote island in the southern Atlantic Ocean.

Retreating Glacier Presents Landslide Threat, Tsunami Risk in Alaskan Fjord

Using NASA satellite imagery and software processing approaches, a group of geoscientists has discovered a landslide-generated tsunami threat in Barry Arm, Alaska, that will likely affect tourists and locals in the surrounding area in the next 20 years.

The Anatomy of Glacial Ice Loss

Combined, Greenland and Antarctica contain enough ice, that if it were to melt all at once, would raise sea levels by nearly 215 feet (65 meters) – making the study and understanding of them not just interesting, but crucial to our near term adaptability and our long term survival in a changing world.

Taking a Measure of Sea Level Rise: Ice Height

Scientists project ice losses from the Greenland and Antarctic Ice Sheets will play a large part in sea level rise in the upcoming century.

Spalte Splits

In summer 2020, a huge piece of ice split off from the Arctic’s largest remaining ice shelf.

Mapping Shallow Seafloors

By combining satellite measurements with ship-based sonar data, researchers are working to fill the gaps in coastal ocean maps.

2020 Arctic Sea Ice Minimum at Second Lowest on Record

An analysis of satellite data by NASA and the NSIDC shows that the 2020 minimum extent, which was likely reached on Sept. 15, measured 1.44 million square miles (3.74 million square kilometers).

Emissions Could Add 15 Inches to 2100 Sea Level Rise, NASA-Led Study Finds

If greenhouse gas emissions continue apace, Greenland and Antarctica’s ice sheets could together contribute more than 15 inches of global sea level rise by 2100.

Where Ice Still Flows into Glacier Bay

In this changing Alaskan landscape, tidewater glaciers are holding on to the bay’s West Arm.

Inlet’s Iceberg Maker Is Nearly Gone

Retreating glaciers have changed how visitors experience Glacier Bay National Park in southeast Alaska.

Grand Plateau Glacier

Views from above show the extent of change across Alaska’s Glacier Bay National Park.

Arctic Lows

Record-low sea ice in July 2020 could be further depleted by a low-pressure system that developed over the Arctic Ocean.

Syncing NASA Laser, ESA Radar for a New Look at Sea Ice

With a small nudge to a satellite’s orbit, scientists will soon have simultaneous laser and radar measurements of ice, providing new insights into Earth’s frozen regions.

Johns Hopkins Glacier

While most glaciers in southeast Alaska are losing an astounding amount of ice, this glacier has been relatively stable.

Space Apps COVID-19 Hackathon Brings 15,000 Together Worldwide

Poetry. Mobile apps to promote mental health. Rooftop gardening solutions. Drone delivery for food. These are just some of the projects participants dreamed up in the NASA Space Apps COVID-19 Challenge, a virtual global hackathon aimed at innovations in response to the COVID-19 pandemic.

Breakup Along the Mackenzie River

Each spring, the Canadian Arctic is the site of a fierce battle between water and ice.

Frozen Finland Thaws

After a harsh winter in northern Finland, warm temperatures rapidly melted snow to cause significant flooding.

Ice Arch Persists Despite Warm Arctic

This natural gatekeeper, which prevents sea ice from exiting the Arctic Ocean and drifting southward into Baffin Bay, was still intact in late May 2020.

Mapping Snow on Arctic Sea Ice

First-of-a-kind maps show how the depth of this insulating snow layer changes from month to month.

NASA’s ICESat-2 Measures Arctic Ocean’s Sea Ice Thickness, Snow Cover

Initial results from NASA’s ICESat-2 satellite suggest that Arctic sea ice has thinned by as much as 20 % since the end of the first ICESat mission (2003-2009).

NASA Space Laser Missions Map 16 Years of Ice Sheet Loss

Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.

A-68A Holding it Together

The huge Antarctic iceberg has floated into warmer waters, but it is still mostly intact.

#EarthDayAtHome with NASA

Fifty years ago, on April 22, 1970, people around the world marked the first Earth Day. Thousands gathered to raise awareness about the importance of protecting our beautiful planet for future generations.

NASA Marks Earth Day’s 50th Anniversary with #EarthDayAtHome

As the world observes the 50th anniversary of Earth Day on Wednesday, April 22, NASA is highlighting the agency’s many contributions to sustaining and improving our home planet’s environment...
