2022 – Ein unvollständiger Rückblick zum Klimawandel.

Die #Klimakrise ist an vielen Orten der Welt bereits mit großer Wucht eingeschlagen. Wir können es uns nicht mehr leisten, Klima gegen andere Themen auszuspielen, sondern müssen den gemeinsamen Nenner sehen, den Kapitalismus
Der Winter. Die Erkenntnis von Wissenschaftler:innen, dass in der Antarktis ein riesiger Gletscher, der #ThwaitesGlacier oder #DoomsdayGlacier, demnächst abbrechen & den Meeresspiegel um 65 cm erhöhen wird, löst Angst aus – bis er wieder vergessen ist.
Der Frühling. Durch die tödliche Dürre im Horn von Afrika kommt es zu entsetzlichen Hungerleiden von Millionen von Menschen.
Bis 2070 könnten 30% des Planeten zu Todeszonen werden. Das wird bis zu 3,5 Milliarden Menschen treffen.

I was privileged to be invited to write a commentary on an interesting recent paper about the roughness of ice shelves by Watkins et al. (2021).
Commentary features this schematic diagram of the #ThwaitesGlacier Eastern Ice Shelf by @MarloWordyBird doi.org/10.1029/2021GL…

The paper that was the subject of the commentary is available here -

Background -
Ice shelves are floating extensions of glaciers that flow on beds hundreds of meters below sea level. They contribute "backstress" restricting outflow from many of the largest glaciers in Antarctica, thus limiting the Antarctic contribution to sea-level rise.

While @GlacierThwaites fieldwork is postponed for the coming Antarctic summer, how much ongoing ice loss is there from #ThwaitesGlacier and nearby glaciers in the Amundsen Sea, and how big is their contribution to sea-level rise? Thread, 1/23
3 separate recent studies provide measurements for individual glaciers or drainage basins based on satellite remote sensing observations:
Rignot et al. (2019) doi.org/10.1073/pnas.1…
Shepherd et al. (2019) doi.org/10.1029/2019GL…
Smith et al. (2020) doi.org/10.1126/scienc…
2/23
In summary, the results of these studies show rates of net ice mass loss from Thwaites and nearby glaciers are now more than six times what they were 30 years ago. This graph shows the progressive increase in net ice loss from Thwaites from the results of Rignot et al. 3/23 Image
