    Antarctica, the Earth's land mass that is now synonymous with bad news, has a new characteristic to worry about A team of scientists from the United Kingdom, Denmark, the Netherlands, and Norway has just discovered three cannons hidden beneath hundreds of feet of ice in the interior of Antarctica. In an article published this month in the journal Geophysical Research Letters, they write that the canyons are in the region where the ice sheets of the eastern and western Antarctic are located, and the deep underground furrows are channeling the flow of ice into the sea. as the two leaves come together. "[If] weather conditions change in Antarctica, we can expect the ice in these channels to flow much faster into the sea, which makes them really important, and we just did not know they existed before now," Kate told BBC News. Winter, a researcher at the University of Northumbria in the United Kingdom and lead author of the article. It is expected that the ice sheets of Antarctica will continue to think while the planet warms; It is already happening to the ice shelves that line the edge of the sheets. If that happens, the resulting change in mass could trigger an acceleration of the ice flow through these furrows and could act as a feedback loop that drives the ice sheet to disintegrate, contributing to sea level rise. The largest of the three guns, which the researchers called Foundation Trough, is more than 217 miles (350 kilometers) long and 22 miles wide. That is approximately the distance between Washington DC and the city of New York. As the BBC points out, this document is the first to leave PolarGAP, a project of the European Space Agency to take observations of a part of the planet that its satellites cannot "see", because they do not orbit around the planet. so south. The PolarGAP project is flying radar-equipped aircraft over those locations to collect data instead of satellites.
