2 New Papers: Scientists Report A Rapid Deceleration Of Greenland Ice Sheet Melt Since 2013
By Kenneth Richard on 16. September 2019
Greenland’s ice sheet mass losses have significantly decelerated since 2013 – a reversal from the rapid retreat from the 1990s to 2012 driven by cloud forcing and the NAO (Ruan et al., 2019). The post-2013 “relatively stable†ice sheet even gained mass during 2017-’18 (Andersen et al., 2019).

Decelerated Greenland Ice Sheet Melt Driven
by Positive Summer North Atlantic Oscillation
“The GrIS lost mass at a rate of about -102 Gt/yr in early 2003, increased to -393 Gt/yr during 2012-2013, but suddenly reduced to no more than 75 Gt/yr during 2013-2014 (Bevis et al., 2019). It is suggested that this deceleration is due to the increased snowfall accumulation driven by the positive phase of summer North Atlantic Oscillation (sNAO; Folland et al., 2009; Chen et al., 2015).â€
