Evidence for massive and abrupt iceberg calving in Antarctica dating back 19,000 to 9,000 years ago is based on an analysis of new, long deep sea sediment cores extracted from the region between the Falkland Islands and the Antarctic Peninsula.
The study in Nature documents that the Antarctic ice sheet is unstable and can abruptly reorganize Southern Hemisphere climate and cause rapid global sea level rise.
What brought about such huge ice-sheet collapses in Antarctica back then, since there was no Anthropocene to implicate? For that, the researchers had to fall back on climate modeling experiments.
This is not to say that global warming is not real, only that there are other real things at work in the universe.
This is not to say that we should not be aware, only that it is not the cause of every crisis.
That is not even to say that we should not act, only that it would be foolish to think that acting to maintain stasis is the only or even the most efficient way forward.
