Written by AZoCleantechFeb 24 2021
A new study reports that glaciers in West Antarctica are moving into the ocean from land faster than ever, leading to increasing global sea levels.

Researchers used a 25-year record of satellite observations to demonstrate, for the first time, wide-ranging increases in ice speed throughout the Getz sector, where some portion of ice accelerated into the ocean by almost 50%.
Led by the University of Leeds, the study describes that in the Getz region, 14 glaciers are thinning and flowing faster than ever into the ocean. From 1994 to 2018, 315 gigatonnes of ice had been lost, increasing the global mean sea level by 0.9 mm, which is equivalent to 126 million Olympic swimming pools of water.
