- Antarctica alone may lift seas a metre by 2100 –
Over a longer time scale, the study concluded, the picture is even grimmer: within 500 years, Earth’s once-frozen continent will have lifted water lines by more than 15 metres (50 feet), reconfiguring the planet’s coastlines.
But independent experts said the study was probably on target.
But the low figure for Antarctica had more to do with gaps in knowledge than differences of opinion.
Wake up call
Building on earlier work, DeConto and David Pollard, a climate scientist at Pennsylvania State University, created computer models integrating for the first time two mechanisms that appeared to solve the puzzle.
As any teenage can tell you, if you put a sealed bottle of water or beer in a freezer, the liquid will expand and crack the container.
“That’s the good news here,” he added. — AFP
