100 Years of Climate Change Visible in Aerial Photographs of Alpine Glaciers
In 1919, the Swiss pilot and photographer Walter Mittelholzer flew over Mont Blanc in a biplane photographing the alpine landscape. Exactly 100 years later, researchers…

NASA’s OMG Mission Raises Plenty of New Questions
Only seven months after NASA’s Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world’s largest island, an OMG crew is back…
New Discovery Signals Rapid Decay in Antarctic Glacier
A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in…
NASA Image of the Day – ‘Snow Swamp’ on Canada’s Lowell Glacier
Over a mere four days this summer, snow from the previous winter melted into a pond of slush on Canada’s Lowell Glacier. Mauri Pelto, a…
NASA Views One of the Most Rapidly Changing Glaciers in the World
The Columbia Glacier descends from an ice field 10,000 feet (3,050 meters) above sea level, down the flanks of the Chugach Mountains, and into a narrow inlet that…
Scientists Reveal How And Why Antarctica’s Glaciers Are Changing
New research review provides insights into the continent’s response to climate warming. Scientists from the University of Maryland, the University of Leeds and the University…
Scientists Discover Bits of the Solar System in an Antarctic Glacier
On rare calm days, the most striking thing you notice at an altitude of more than 8,000 feet on an Antarctic glacier is the silence….
New Dating Techniques Show Germany Was Covered by Glaciers 450,000 Years Ago
Using state-of-the-art dating techniques researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have obtained new chronological data for the timing of…
NASA Study Shows Wind and Warm Water Accelerating Glacier Melt
New research from NASA reveals the Antarctic glaciers that accelerated the fastest between 2008 and 2014 and finds that the most likely cause of their…
New NASA Research Identifies Pathway for Greenland Meltwater to Reach Ocean
New NASA research found that large crevasses provide aquifer water upstream of Greenland’s Helheim Glacier with a clear escape to the ocean. This discovery helps…
New Threat to East Antarctic Ice
New research reveals two seafloor gateways that could allow warm ocean water to reach the base of Totten Glacier, raising concerns about how it will…
New Research Explains Acceleration of Greenland’s Inland Ice
By developing a new model investigate the effects of meltwater on Greenland glaciers, researchers discovered that meltwater warms the ice sheet, which then softens, deforms,…
Massive Ice Island Breaks Free from Greenland’s Petermann Glacier
Confirmed by data taken by MODIS, the Moderate Resolution Imaging Spectroradiometer aboard NASA’s Terra and Aqua satellites, a 120 square km ice island has broken…
1930s Photos Reveal History of Greenland Glaciers
Rediscovered aerial photos of Greenland from the 1930s have allowed scientists to construct the history of the glacier retreat and advance in the area. The…
Columbia Glacier Retreating to the Sea in Alaska
It took seven years, but the photographic record of the Columbia Glacier in Prince William Sound on Alaska’s southern central Pacific coast has been compiled…
Study Blames Warm Ocean Currents for Majority of Ice Loss in Antarctica
Using new techniques with satellite measurements to differentiate between the warm ocean currents attacking the underside ice shelves and warm air melting it from above,…
Himalayan Glaciers Declining Less Rapidly than was Previously Thought
A new study suggests that the decline of the Himalayan glaciers due to climate change may be occurring at a slower rate than previously thought….
