"Rising from the Antarctic, a Climate Alarm"[1] was a much much more interesting article that covered way more than the simple, superficial change in sea-level that this article focuses upon. It talked about the antarctic's impact on carbon-capture/carbon-release, and plenty of other nuanced climate issues. That there's short/medium term threat of this glacier potentially rising sea levels seems pale in comparison to the total net climate impact we could be facing. Where-as this "doomsday" article focuses on a single symptom of the gaian ecosystem being deeply out of whack.
> By some estimates the oceans have taken up about 25 percent of the excess carbon dioxide, and more than 90 percent of the excess heat, that has resulted from burning of fossil fuels and other human activities since the 19th century. But the deep ocean water that upwells around Antarctica contains even more carbon dioxide — not from current emissions, but dissolved over centuries from organic matter including decaying marine organisms, tiny and immense, that sink when they die.
For what it's worth, nearly every article is focused around the ocean-level rises. WaPo article[2] was similar, so was science.org[3] (although some really good details on the situation/research) here.
One random thing I'll note, the science.org article showed a map of the area of concern, & wow, it's remarkable what a vast area of glacier could run out to sea via a relatively-small <200 km ice-wall giving way, failing to retain the continent's ice. It sounds absurd but, like... can we reinforce/build a man made retaining wall?
