Huge Crater Under Greenland Glacier Surprises Scientists With Its True Age

by

An enormous impact crater, hiding deep beneath Greenland’s Hiawatha glacier, is probably the result of a kilometer-wide asteroid that crashed into Earth 58 million years ago. That’s much older than scientists presumed – roughly eight million years after the infamous impact that killed off most dinosaurs.   When the Hiawatha crater was first discovered in … Read more

Iceland glaciers: Cold blob in Atlantic may be slowing ice loss from Iceland’s glaciers

by

Iceland’s glaciers are melting as a consequence of climate change, but the rate of loss has fallen in the past decade, perhaps because a blob of cold water in the Atlantic is cooling the island Environment 11 February 2022 By Jason Arunn Murugesu Skaftafellsjökull glacier in Vatnajokull National Park, Iceland Guitar photographer/Shutterstock Iceland’s glaciers are … Read more

Mt. Everest’s highest glacier lost 2,000 years worth of ice since the 1990s

by

Even the glaciers on Mount Everest are not safe from climate change, new research suggests.  In a record-setting study, a team of scientists scaled the world’s highest peak to monitor the mountain’s highest-altitude glacier — the South Col Glacier, standing nearly 26,000 feet (8,000 meters) above sea level — for signs of climate-related ice loss. … Read more

Everest’s Highest Glacier Lost 2,000 Years of Ice in Just 25 Years, Says New Study

by

The climate crisis enveloping Earth impacts the lowest depths of the sea and the most remote parts of the planet. And new research shows that it’s also causing change at the highest points of the world.   Scientists studying South Col – Mount Everest’s highest glacier – have reported that rapid ice loss is occurring … Read more

Glacier Lakes Make Permanent Ice Disappear Over Twice as Fast, Study Reveals

by

Glaciers are retreating faster globally due to climate change but they melt more quickly when they flow into a lake than when they end on land, with consequences for water supplies, a new study found on Thursday.   The Swiss-funded study is the first large-scale, detailed analysis of the phenomenon in mountain glaciers and could … Read more

What Antarctica’s ‘Doomsday’ Glacier Could Mean For The World

by

The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier hemorrhages more and more ice.   Adding 65cm to global sea levels would be coastline-changing amounts. For context, … Read more

Antarctica’s ‘Doomsday Glacier’ could meet its doom within 3 years

by

Time is melting away for one of Antarctica‘s biggest glaciers, and its rapid deterioration could end with the ice shelf’s complete collapse in just a few years, researchers warned at a virtual press briefing on Monday (Dec. 13) at the annual meeting of the American Geophysical Union (AGU).  Thwaites glacier in western Antarctica is the … Read more

Ice Shelf at Antarctica’s ‘Doomsday Glacier’ Won’t Last 5 Years, Scientists Warn

by

A crucial ice shelf on Antarctica‘s Thwaites Glacier is on track to collapse within five years, accelerating the melting of the notorious ‘doomsday glacier’. Thwaites, which is the size of Florida, is already melting quickly, losing about 50 billion tons of ice per year. The glacier earned its grim nickname because its total collapse would raise global sea … Read more
