The ground beneath #Antarctica's most vulnerable #glacier has been mapped for the first time, helping scientists to better understand how it is being affected by climate change. Analysis of the geology below the #Thwaites #Glacier in #WestAntarctica shows there is less sedimentary rock than expected—a finding that could affect how the ice slides and melts in the coming decades.

There are 6 #cumulative #climate #tippingpoints:
Ice melt in #Greenland & #WestAntarctica
#CO2 #CH4 #GulfStream #Monsoon #Amazon
They don't seem #linear, but #exponential!
P.#Taalas #WMO: "#Sealevel will rise by 30 m"
H.#Wanless 2060 +7 m
H.#Winkler 2050 +14 m (or 2030?) exponentiell to polarportal.dk-curve

Although we're concentrating on #WestAntarctica, the ice sheet in #QueenMaudLand in East Antarctica is not stable. Large amounts of ice have #melted in the past, most recently 5,000 years ago. #SWAIS2C https://partner.sciencenorway.no/antarctica-climate-environment/the-ice-in-antarctica-has-melted-before/2180947

@osma Se olisi aikamoinen pala purtavaksi... ymmärtääkseni vesi virtaa keskimäärin ulospäin, koska suuret joet lisäävät niin paljon vettä Itämereen. Tarvittaisiin mittava pumppaamo!

Itse asiassa John Moore Lapin yliopistosta on tutkinut patojen rakentamista Länsi-Antarktiksen jäätiköiden tielle...

Een Britse wetenschapper heeft een broedkolonie van keizerspinguïns in West-Antarctica ontdekt via satellietfoto's. Hij kwam ze op het spoor toen hij bruine vlekken op het ijs zag, die uitwerpselen van de dieren bleken te zijn.
