Get out the lifeboats! Antarctica is melting.Considers an article in 'Nature' which suggests large portions of the Antarctic ice cap may have melted just three million years ago. Citing evidence of sea-plankton remains in the Transantarctic Mountains at altitudes where no sea should have been, ...
The concern is that the melting sea ice could start a cycle that might cause even more ice to melt. The ice loss problems in Antarctica are fairly recent, but the same is not true at the North Pole. where the low level of sea ice has been a concern for years. But the present ...
Scientists in Antarctica have recorded, for the first time, unusually warm water beneath a glacier (冰川) the size of Florida that is already melting and contributing to a rise in sea levels. The researchers, working on the Thwaites Glacier, recorded water temperatures at the base of the ice...
Human-caused climate change has made some of the continent's ice not firm, and the West Antarctic ice sheets especially have been slowly melting into the sea. If patterns continue, the coastal glaciers supporting the large ice sheets could fall down, causing sea level to rise a minimum of ...
Scientists Find Surprise Hidden in Earth’s Mantle The Sun Turned Blue 200 Years Ago. Now We Know Why Scientists Found Lost Landforms Deep Under the Sea A Massive Solar Star Turned Tractors into 'Demons' The First Ice-Free Arctic Day Could Arrive in 2027 ...
Now human activity is acting as a force of nature, propelling what has been a very stable sea level during all of modern human civilization back into overdrive. "The problem is that the melting ice and rising sea tends to follow an exponential path," said Englander. "That would change or...
(十年 ),according to a report released by China's MOST this year.Also,it is predicted that the melting conditions of the Antarctic ice sheet will continue to increase and will be almost impossible to reverse(逆转),even if global emissions reduction goals are reached.(在南极洲,其面积约1230万...
They conclude that the massive piece will drift (漂移) through the South Atlantic for several years before breaking into smaller pieces and melting. Since the iceberg has already replaced the water it will add to the ocean as it melts, it will not contribute to rising sea levels.Though A-...
Antarctica, Is It Really In Danger? With all of the fervor these days about the dangers of global warming many people are concerned about the fate of Antarctica. The fears are that the ice that makes up the continent is melting faster than normal and not freezing back as it usually does ...
Naughten’s study looked at the part of the West Antarctic Ice Sheet that is most at risk from melting from below, near the Amundsen Sea. It includes the very large Thwaites ice shelf that is melting so fast it is called “the Doomsday Glacier.” ...
