] Whether in your teeth or in an Antarctic glacier, the cavities are bad sign.
The Thwaites glacier in West China has developed a cavity about two-thirds of Manhattan and about 1,000 feet high, according to a NASA Jet Propulsion Laboratory study published Thursday. This empty space has the negative effect of speeding up the speed at which the glacier melts and in turn how fast the sea level rises.
A study by the New York Times of 1947 (19459018) from 2017 considered Thwaites Glacier, which is largely the size of Florida, and how much ice it regularly throws out and feeds into the ocean. The problem with this glacier is that it throws out a lot and accounts for about 4 percent of the total sea level is increasing around the world, according to NASA.
The newly discovered cavity previously contained 14 billion tons of ice, which is now water and that means that the Thwaites glacier is melting faster than anyone thought. If the whole glacier melts, it would raise the sea surface by more than two feet.
In 2018, a report from over 40 tillage organs looking at istab in Antarctica showed that the continent has lost three trillion tonnes of ice over 25 years, primarily from the West Atlantic market. This has had a dramatic effect on the ocean surface, which has only risen 7 and a half millimeters from the continent alone.
Melting of glaciers and sea level is rising, caused by global climate change, has devastating effects on wildlife and coastal communities. As sea levels rise, coastal communities and low-lying areas become more exposed to flooding and will force millions of people to move.
The discovery of this cavity suggests that the destruction is faster than we previously thought.
