Consider the following statements regarding the Thwaites Glacier and its implications for sea-level rise: I. Thwaites Glacier is located in West Antarctica and drains into the Amundsen Sea, exposing it to relatively warm Circumpolar Deep Water intrusions. II. The bedrock beneath Thwaites Glacier slopes downward inland below sea level, increasing its susceptibility to Marine Ice Sheet Instability (MISI). III. The floating ice shelf in front of Thwaites Glacier acts as a buttress that restrains the seaward flow of inland ice. IV. The destabilisation of Thwaites Glacier can trigger accelerated ice loss from neighbouring glaciers within the West Antarctic Ice Sheet. V. The complete collapse of Thwaites Glacier alone is projected to cause multi-metre global sea-level rise within a few decades. How many of the above statements are correct?
