Antarctic Climate Evolution is the first book dedicated to furthering knowledge on the evolution of the world’s largest ice sheet over its ~34 million year history. The world’s largest ice sheets may be in less danger of sudden collapse than previously predicted, according to new findings led by the University of Michigan. The topography of the bed beneath the glacier is a key control of future ice loss, but is not currently well enough known to satisfy the requirements of ice sheet models predicting glacier behaviour. As part of the TARSAN project, he has helped developed the fiber-optic moorings of the AMIGOS weather stations and is developing a distributed acoustic monitoring system for both ice shelf and the ocean below for testing at Thwaites in 2021/2022.

Retirees in Miami are moving inland. In How to Prepare for Climate Change, bestselling self-help author David Pogue offers sensible, deeply researched advice for how the rest of us should start to ready ourselves for the years ahead. If the glacier melts entirely, it could trigger a 10-foot rise in sea levels. Abstract. The results have been used to map the ocean currents underneath the floating part of the glacier.

Currently, Thwaites' ice loss contributes approximately 4% to the annual rise in global sea-levels, with the potential to add 65cm in total should the whole glacier collapse. According to a study published in the Friday, June 11, 2021 issue of Science Advances, the critical Antarctic glacier is looking more vulnerable as satellite images show the ice shelf that blocks it from collapsing into the sea is breaking up much faster than before and spawning huge icebergs. (2021, April 9). Thwaites Glacier was moving closer to the threshold, and its collapse could reportedly lead to a nearly 3 feet rise in sea levels in the event of a sudden collapse.
