Sea level rise possibly three times as much than IPCC estimated

Up to 1.5 m possible until 2100.

The research group is not the first to suggest that the IPCC's forecast of an average rise in global sea levels of 28-43cm by 2100 is too conservative.

The IPCC was unable to include the contribution from "accelerated" melting of polar ice sheets as water temperatures warm because the processes involved were not yet understood.
The new analysis comes from a UK/Finnish team which has built a computer model linking temperatures to sea levels for the last two millennia.

Even 1 m would mean low countries like Bangladesh and the Ganges region practically being wiped of the map.

The British govt has basically written off significant chunks of England as impossible to save.
