Antarctic heat – a horrifying reminder of the future with global heating

“Shocking,” said the Met Office head; “bonkers,” according to an Antarctic researcher. The heat at both ends of the planet this week has scientists straining for adjectives. 40°C above normal in Antarctica,
30°C hotter than usual in the Arctic.

With temperatures so much above anything on record, scientists had to confirm that, no, it isn’t a typo:
this is really happening.

Last week, the Conger ice shelf, which sits off the East Antarctic coast and is around 1,200 square kilometers across, collapsed completely. Ice sheets hold back the flow of ice into the sea.
“If they collapse, then ice flow from inland accelerates and leads to sea level rise,” said Andrew Mackintosh, a scientist at Monash University in Australia.

A natural reaction to such news is to fear the ice sheets might collapse entirely. If the West Antarctic ice sheet collapsed into theocean, global sea-levels could rise several metres – much faster and
further than expected – swamping coastal cities. That is not likely to happen soon, but the polar heat is a horrifying reminder of the stakes involved.
