Meltdown in Greenland: Ice Shelves Lose Over a Third of Their Volume
A new study shows the largest floating ice shelves in North Greenland have lost more than a third of their volume since 1978, largely due…
SWOT Mission: See an Unprecedented View of Global Sea Levels [Video]
Data on sea surface heights around the world from the international Surface Water and Ocean Topography mission yields a mesmerizing view of the planet’s ocean….
Chilling Reality: An Unseen Factor Is Accelerating Antarctic Glacier Meltdown
Simulations showed that meltwater flowing beneath Antarctic glaciers accelerated sea-level rise by 15% by 2300, suggesting it should be factored into future projections. A new…
In Depth: The Unsettling Findings Beneath Antarctica’s Thinning Ice Sheets
A recent theory illustrates the mechanism by which water underneath glaciers may surge — creating a dangerous feedback cycle. Two Georgia Tech researchers, Alex Robel…
Drowning Predictions: Yearly 100-Year Floods Loom on the Horizon
Some floods are so severe they rarely strike more than once a century, but rising seas could threaten coastal communities with yearly extreme floods by…
Time Is Running Out: Coastal Wetlands Can’t Keep Up With Climate Change, Warns New Study
The survival of marshes and other vulnerable coastal regions hinges on the ability to restrict global warming to under 2 degrees Celsius (3.6 degrees Fahrenheit),…
Unearthing the Past: Ice Core Data Reveals Greenland’s Unexpected Ice-Free History
New analysis of sediments from the Camp Century ice core reveals that northwestern Greenland was ice-free during the Marine Isotope Stage (MIS) 11 interglacial period….
Greenland’s Hidden History: Geoscientists Challenge Pre-Existing Climate Beliefs
Scientists report much of the Artic island’s ice melted as recently as 416,000 years ago, which has implications for sea-level rise. Newly analyzed samples from…
Ice Core From Secret Cold War Army Mission Reveals Greenland Melted Recently
Long-lost ice core reveals that most of Greenland was green 416,000 years ago. A large portion of Greenland was an ice-free tundra landscape—perhaps covered by…
Scientists Discover Astonishing 36-Million-Year Geological Cycle That Triggers Bursts of Biodiversity
Tectonic changes alter sea levels which can create breeding grounds for life. Researchers have discovered that Earth’s tectonic plate movements cause sea levels to rise…
Earth Tilted: We’ve Pumped So Much Groundwater That Earth’s Spin Shifted
The shifting of mass and consequent sea level rise due to groundwater withdrawal has caused the Earth’s rotational pole to wander nearly a meter in…
Chilling Secrets: Rocks Beneath Antarctic Ice Sheet Reveal Surprising Past
Researchers from the International Thwaites Glacier Collaboration found that the West Antarctic Ice Sheet had been thinner in the past and had regrown, suggesting that…
Meltdown: The Alarmingly Rapid Disappearance of Greenland’s Glaciers
Research has discovered an extensive and continuous loss of glaciers and ice caps across Greenland, starting from the early years of the 20th century. This…
We Asked a NASA Scientist: Why is Sea Level Rising?
Why is sea level rising? So on global scales, sea level is rising really because of our warming climate. There’s two main factors causing sea…
Melting Point: Rapid Retreat at Petermann Glacier
Decades of retreat are visible from above, but harder-to-see changes below the waterline could also affect this iconic glacier’s future. Petermann Glacier is one of…
Marsh Madness: Coastal Wetlands Race Against Rising Seas
Salt marshes along the U.S. East Coast have been building elevation to keep pace with rising sea levels over the last century, according to a…
Decade of the Worst: Polar Ice Sheet Melting Shatters Records
