USA – The Florida-wide Thwaites Glacier currently accounts for around 4 per cent of global sea level rise; it has enough ice to raise the oceans of the world by more than 65cm if it melts.
NASA scientists have discovered a huge cavity at the bottom of the remote Thwaites Glacier in Antarctica, which covers the two-thirds of the Manhattan scale and they describe it as a "changing" climate change signal, according to their study, namely published by the magazine Science Advances. The researchers used a vibrant ice and satellite radar that could have high resolution data to find a high capacity of 300 meters, which was "big enough to include 14 billion tonnes of ice – and & # 39; Most ice melted over the last three years. " The leading author of the study, Pietro Milillo of the NASA Jet Propulsion Laboratory (JPL) stated that "[the size of] cauliflower under a glacier plays an important role in melting and "as more heat and water is under the glacier, it melts faster".
"On the eastern side of the glacier, the online line retreat passes through small channels, perhaps a large kilometer, such as fingers reaching under the glacier to melt under", he said.
According to JPL, the discovery highlights the need for detailed observations of Antarctic glaciers subtlets to calculate "how fast global sea levels will rise in response to climate change". A small guy (Alle-alle) flew near the Kronebeene archipelago in the Svalbard archipelago, at Cefn Arctig, on July 21, 2015. Milillo was echoed by Eric Rignot, one of the co-authors of the study, who said that scientists have "Doubt for years that Thwaites had not been involved in the fund under her" and that a new generation of satellites had helped them "see the final details".
"Understanding the details of how the sea melts off this glacier is essential for a project to have an impact on sea level rise in the next decades", he stressed. The study specifically stated that the Thwaites Glacier holds enough ice to raise sea level in "just over 2 feet (65 centimeters)".
More than that, the ice formation was described as door stopping, preventing adjoining glaciers from slipping towards the sea.
