Mountain Glaciers are Shrinking Due to Climate Change, And That's Bad News

News 18  

Mountain glaciers shrinking due to climate change are less voluminous than previously understood, putting millions who depend on them for water supply at risk, researchers reported Monday. “We generally think about glaciers as solid ice that may melt in summer, but ice actually flows like thick syrup under its own weight,” said Morlighem. “Using satellite imagery, we are able to track the motion of these glaciers from space at the global scale.” To create an ice flow database, the researchers studied more than 800,000 pairs of before-and-after satellite images of glaciers, including large ice caps, narrow alpine glaciers, slow valley glaciers and fast tidewater glaciers. “Because there is less ice stored in the world’s glaciers than we had thought they will disappear earlier than expected, and so the communities that depend on their ice and water will experience the worst effects of climate change sooner,” said Andrew Shepherd, director of the Centre for Polar Observation and Modelling at the University of Leeds.

Greenland has lost more ice than previously thought: study

The Hindu  

Climate change has caused Greenland’s ice sheet to lose 20% more ice than previously thought, according to research published Wednesday that used satellite imagery to track the retreat of glaciers over the past four decades. Previous studies have found that about 5,000 gigatons of ice has been lost from the surface of the Greenland ice sheet in the past two …

Has the future sea level rise been correctly estimated?

The Hindu  

Researchers have uncovered a previously unseen way in which ice and an ocean interacts. According to glaciologists, this could mean that the climate community has been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration. Using satellite radar data from three European missions, the team learned that the Petermann Glacier’s grounding line — where ice …

Live Mint  

New surveys have revealed that Thwaites Glacier, which is also known as the "doomsday glacier", is on the verge of collapse. The collapse of the glacier, which is around the size of Gujarat, could lead to a catastrophic rise in global sea levels, without any contribution from Greenland or the Himalayas. The real concern is that Thwaites Glacier acts as …

For years now, scientists have been warily watching Antarctica’s Thwaites Glacier for its capability to propel a catastrophic sea level rise. A complete collapse of the ‘Doomsday Glacier’ could lead to sea level rise of more than two feet. With the glacier acting as a dam of sorts for the surrounding ice, its breakdown could ultimately lead to a global …
