Third of Antarctic ice shelves ‘will collapse amid 4C global heating’

Unimaginable amounts' of water will flow into oceans if that temperature rise occurs and ice buffers vanish, warn UK scientists

More than a third of the vast floating platforms of ice surrounding Antarctica could be at risk of collapsing and releasing unimaginable amounts" of water into the sea if global temperatures reach 4C above pre-industrial levels, UK scientists say.

Researchers from the University of Reading said that limiting the temperature rise to 2C could halve the area at risk and avoid a drastic rise in sea levels.
