Return to rapid ice loss in Greenland and record loss in 2019 detected by the GRACE-FO satellites

I. Sasgen, B. Wouters, et al.

Greenland's ice loss has surged to alarming levels, reaching a staggering 532 ± 58 Gt yr⁻¹ in 2019, eclipsing even the notorious 2012 record. This study, conducted by Ingo Sasgen, Bert Wouters, Alex S. Gardner, Michalea D. King, Marco Tedesco, Felix W. Landerer, Christoph Dahle, Himanshu Save, and Xavier Fettweis, sheds light on the recent fluctuations in melt rates and their implications for global sea level rise.

Abstract
Between 2003 and 2016, Greenland experienced significant ice loss, contributing substantially to sea level rise. This loss slowed in 2017 and 2018 due to unusually cold summers in western Greenland and increased snowfall in the east. However, GRACE-FO data reveal a return to high melt rates in 2019, resulting in a record annual mass loss of 532 ± 58 Gt yr⁻¹, exceeding even the 2012 record.
