1000 m below sea level. Runaway sea-level rise resulting from retreat of Antarctica's Thwaites glacier depends on humans' substantially cutting GHG emissions. It covers an area of 192,000 sqkm — in comparison, Tasmania is 68,401 sqkm and Victoria is 227,444 sqkm. Thwaites was nearly seven stories high here, at its eastern edge, and the bluish cliff glowed against the grayscale sky.It was snowing, and foggy, and the glacier appeared like something out of this world. The Thwaites has moved … When glaciers melt and lose weight, they float off the land where they used to be situated. A large area of the West Antarctic Ice Sheet flows to the ocean via Thwaites Glacier, which extends over 192,000 sq kms (74,000 sq miles), an area the size of Florida or the island of Britain. Thwaites Glacier is a vast brick of ice flowing into Pine Island Bay in western Antarctica. It is predicted that it will gradually melt, leading to an irreversible collapse over the next 200 to … Read all of the reporting from the eight-week expedition. Nilas ice; Posts: 1414; Liked: 504; Likes Given: 243 ; Re: Thwaites Glacier Discussion « Reply #280 on: May 18, 2020, 06:34:30 PM » I want to remind you about my posting … “Thwaites is a terrifying glacier,” Anandakrishnan says simply. “It’s amazing to go to a place like Thwaites to see the changes taking place right before your eyes,” said Dr Hogan. Simplified grounding line image of an ice sheet. Thwaites glacier in Antarctica might be past the point of no return. From: Huybrechts et al., 2009. Thwaites Glacier covers 74,000 square miles—an area the size of Florida—and is particularly susceptible to climate and ocean changes. Its melt already accounts for about 4% of global sea rise, Georgia Tech reported. The ice shelf is thinning rapidly and the grounding line is retreating. Thwaites Glacier in West Antarctica. The Thwaites Glacier is one of the most dangerous glaciers in the world, and scientists are eager to travel to Antarctica to study it. The gigantic Thwaites glacier covers 293,000sq kms — about half the area of the United Kingdom. ... That’s more than 2 degrees Celsius (3.6 degrees Fahrenheit) warmer than that location’s freezing point owing the chemistry of saltier water. The red dot shows the approximate location of the Nathaniel B. Palmer research vessel each day. Thwaites Glacier, roughly the size of Florida, is melting at an increasingly fast rate. So long as Thwaites connects with the earth beneath it, the glacier will block warm waters from creeping up to the broader, thicker ice — the Western Antarctic Ice Sheet — sitting behind it.
