I'm afraid the Antarctic Doomsday glaciers have lost their doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier."
Antarctica is not warming, it's cooling, with the evidence showing it has been doing so for at least 40 years, maybe more than 70 (Singh and Polvani, 2020; Bello et al, 2022; Zhang et al, 2022; Zhu et al, 2021). So no "global" warming, and no polar amplification - at least not at the South Pole. Therefore man-made climate change cannot be causing any change in the melt rate of WAIS including Thwaites. Because, you know, it would have to get warmer for the ice to melt. So if there is an increase in the movement of the ice it is coming from heat below, and that is what research suggests - geothermal flux (Dziadek et al, 2021; Martos et al, 2017).
If it is hot rock melting ice, there's nothing we can do about it, of course.
Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.
