Four new studies in prestigious journals show <\/strong>Antarctic ice shelf  as stable as ever. <\/strong>

Andreasen et al (2023)<\/a> finds net gain<\/strong><\/h3>\n\n\n\n

A\u00a0study<\/a>\u00a0by Julia R. Andreasen and colleagues looked at the changes in ice shelves, Antarctic-wide, using MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data from 2009 to 2019.<\/p>\n\n\n\n

They found that over the period 2009-2019, overall Antarctic ice shelf area grew<\/strong> by 5305\u2009km2<\/sup>.<\/strong><\/p>\n\n\n\n

18 ice shelves retreated somewhat and 16 larger shelves grew in terms of area. \u201cOur observations show that Antarctic ice shelves gained 661\u2009Gt of ice mass over the past decade,\u201d the scientists summarized.<\/p>\n\n\n\n

Banwell et al (2023)<\/a>\u00a0meltwater volume dropped<\/strong><\/h3>\n\n\n\n

Another new paper by Banwell et al<\/a> published in the journal Geophysical Research Letters looked at the duration and amount of surface ice melting on Antarctica\u2019s ice shelves from 1980 to 2021<\/strong>, using microwave satellite data the snow model SNOWPACK.<\/p>\n\n\n\n

Result: They found that the highest meltwater volumes were produced on the Peninsula, reaching a peak in the 1992\/1993 and 1994\/1995, and that SNOWPACK calculated \u201ca small, but significant,\u00a0decreasing trend in both annual melt days and\u00a0meltwater production volume over the 41 years<\/strong>.\u201d<\/p>\n\n\n\n

Frazer et al (2023)<\/a><\/strong><\/h3>\n\n\n\n

Another study published in Nature<\/a> authored by Frazer et al (2023) found that although West Antarctica \u2013 particularly from Pine Island and Thwaites glaciers \u2013 has seen dramatic ice losses in recent decades, projections of their future rate are confounded by limited observations.<\/p>\n\n\n\n

Also, looking at the period 2003 and 2015, they found rates of glacier retreat and acceleration to be extensive along the Bellingshausen Sea coastline, but slowed along the Amundsen Sea<\/strong>.<\/p>\n\n\n\n

The authors conclude: Our results provide direct observations that the pace, magnitude and extent of ice destabilization around West Antarctica vary by location<\/strong>, with the Amundsen Sea response most sensitive to interdecadal atmosphere-ocean variability.<\/p>\n\n\n\n

Baico et al (2023)<\/strong><\/a> 35 meters thinner thousands of years ago<\/strong><\/h3>\n\n\n\n

Finally, in yet another new published paper by Baico et al (2023)<\/a>, the authors looked at subglacial bedrock cores show that the West Antarctic Ice Sheet (WAIS) between Thwaites and Pope glaciers and found it \u201cwas at least 35\u2009m thinner than present in the past several thousand years and then subsequently thickened.\u201d<\/p>\n\n\n\n

Moreover: \u201cA past episode of ice sheet thinning that took place in a similar, although not identical, climate was not irreversible<\/strong>. We propose that the past thinning\u2013thickening cycle was due to a glacioisostatic rebound feedback, similar to that invoked as a possible stabilizing mechanism for current grounding line retreat, in which isostatic uplift caused by Early Holocene thinning led to relative sea level fall favoring grounding line advance.\u201d<\/p>\n\n\n\n
