  1. "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  2. 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.
