Melting ice sheets threaten defences
Sea levels could rise by as much as 1.4 metres (4.6 feet) by 2100 – more than twice previous estimates – according to new studies showing that one of the Antarctic’s massive ice sheets is more vulnerable to melting than previously thought.
This would inundate many densely-populated regions, as well as threaten the flood defences of many coastal cities from San Francisco to St Petersburg, in addition to posing an insurmountable problem for low-lying island states where there is nowhere else for their populations to go.
