A new study published by Nature Geoscience has reported that one of the biggest glaciers in Antarctica, the Thwaites glacier which is also known as the ‘Doomsday glacier’ is losing its ice at the fastest rate in the last 5,500 years.
The researchers highlighted that the 75,000-square feet glacier which is bigger than the state of Himachal Pradesh is posing a serious threat to global sea-level rise. The results were yielded by analyzing the prehistoric seashells and penguin fossils found on the arctic beaches through radiocarbon dating. These fossil remains are about 5,500 years old when the Earth was warmer as compared to today’s temperature and that rose the sea level back then.
The study adds that the glacier has been melting at a rapid pace and increasing the sea level at the rate of 0.14 inches per year. In the past 30 years, the rate of rising sea level has spiked to 1.57 inches per year which is the highest in the past 5,500 years. There is a major concern that if this melting rate continues it will raise the global sea level by 10%. Many coastal cities and countries such as New York, Bangladesh, Netherlands and Miami are at a larger risk, the study adds.
