Pumping seawater into Antarctica is unlikely to halt sea-level rise.

Pumping seawater onto the Antarctic landmass to form ice and stop sea levels rising stands little chance of success, scientists say.\u00a0<\/strong><\/div>\n

LONDON, 10 March, 2016\u00a0<\/em>\u2013\u00a0<\/span>Sea level rise is likely to be a problem too big to handle. Geoengineers will not be able to magic away the rising tides, according to new research.<\/span><\/p>\n

In particular, they will not be able\u00a0to pump water from the sea and store it as ice<\/a>\u00a0on the continent of Antarctica. That is because, unless they pump it enormous distances, that will only accelerate the flow of the glaciers and it will all end up back in the sea again, a study in the journal\u00a0Earth System Dynamics<\/a>\u00a0says.\u00a0<\/span><\/p>\n

Geoengineering is sometimes produced as the high-technology solution to the environmental problems of climate change: if humans don\u2019t change their ways and start reducing greenhouse gas emissions, say the proponents of technofix, human ingenuity will no doubt devise a different answer.\u00a0<\/span><\/p>\n

But, repeatedly, closer examination has made such solutions ever less plausible. Scientists have dismissed\u00a0the idea that the melting of the Arctic can be reversed<\/a>,\u00a0have only tentatively conceded that\u00a0technology could dampen the force of a hurricane<\/a>,<\/span>\u00a0and have found that\u00a0<\/span>\u2013<\/span>\u00a0instead of cooling the Earth \u2013 attempts to control climate change could either\u00a0make things worse<\/a>\u00a0or\u00a0seriously disrupt rainfall patterns<\/a>.\u00a0\u00a0\u00a0On balance, scientists believe that\u00a0most of the big geo-engineering ideas won\u2019t work<\/a>.\u00a0<\/span><\/p>\n

Deep freeze<\/strong><\/p>\n

And now a team from the Potsdam Institute for Climate Impact Research has poured cold water on the idea of pouring cold water onto the ice cap.\u00a0<\/span><\/p>\n

The idea is a simple one. Are sea levels rising 3mm a year because the world is warming? Then pump the sea high onto the Antarctic landmass where it will freeze and stay frozen for a millennium.<\/span><\/p>\n
