Along with this, further reduction of shelf ice is predicted, and it seems that it is almost undoubted that the environment of the earth is in the process of rapid change.
If there's any good news about the rift in Larsen C, it's that the ice shelf"is already floating in the ocean, so it has already displaced an equivalent water mass and minutely raised sea level as a result," MacGregor previously said.
They find that, overall, around 13% of the ice sheets is PSI, with ice shelves in the Amundsen(7% PSI) and Bellingshausen(5% PSI) seas being the most susceptible to further ice loss.
The authors use dating techniques applied to the sediments to show that an ocean cavity under the ice shelf, behind the seafloor ridge, began to form around 1945, following a pulse of warmth associated with El Nino events in the tropical Pacific Ocean.
Glaciologist Robert Thomas of EG&G Technical Services at NASA's Wallops Flight Facility in Virginia has long believed that the ice shelves act like a cork in a bottle, greatly slowing glaciers' procession to the sea.
If there's any good news about the rift in Larsen C, it's that the ice shelf“is already floating in the ocean, so it has already displaced an equivalent water mass and minutely raised sea level as a result,” MacGregor said.
Fricker explained in a tweet:“This event is part of the ice shelf's normal cycle though and, while there is much to be concerned about in Antarctica, there is no cause for alarm yet for this particular ice shelf.”.
