That said, I still say 99% of people at the operational coalface put 110% every day into making Australia safer and more prosperous. I’ve never experienced more passion in a public service. Anywhere.

Final words: It is likely too late for the Amundsen [region] but reducing CO2 and other greenhouse emissions have potential to save the larger Antarctic glacial ice shelves".
The observational record is too short, regionality too high to unequivocally attribute change across the ocean-ice-atmosphere & ecosystem.

Key message from "Global impacts of climate extremes in polar regions: is Antarctica reaching a TP?" workshop:
Shallow Antarctic ice cores are urgently needed to connect the long-term record with recent abrupt changes. I.e., sea-ice decline, ocean heat waves, atmospheric warming.
