ANTARCTICA : Huge Glaciers, Huge Risk
ANTARCTICA: Huge Glaciers, Huge Risk - By Swati Yadav Change in Antarctica is resulting in rising temperatures and increasing snowmelt and ice loss. A summary study in 2018 incorporating calculations and data from many other studies estimated that total ice loss in Antarctica due to climate change was 43 giga tons per year on average during the period from 1992 to 2002 but has accelerated to an average of 220 giga tons per year during the five years from 2012 to 2017. Total mass loss over the period 1992–2018 was likely 2720 giga tons for the grounded part of the Antarctic ice sheet. Particularly strong warming has been noted on the Antarctic Peninsula. A study in 2009 noted for the first time that the continent-wide average surface temperature trend of Antarctica was slightly positive from 1957 to 2006....
