Scientists have watched in horror as its retreat has accelerated significantly. Now, as detailed in a study published by the International Thwaites Glacier Collaboration (ITGC) and spotted by Wired, large cracks forming in the ice shelf are continuing to weaken its structural integrity. Doomsday has never been closer. If it were to collapse under its own weight, scientists suggest it could ultimately trigger up to 11 feet of global sea level rise, meaning certain devastation for tens of millions of people.
Going back to early this year, the megaberg weighed around one trillion tonnes - about 100 million times as heavy as the Eiffel Tower in Paris. At its peak, A23a was around 1,540 sq miles in area - more than twice the size of Greater London (607 sq miles) - and a whopping 1,312 feet thick. Now, it is 683 square miles and 37 miles at its widest point, according to AFP analysis of satellite images, making it less than half its original size.
