The Scotsman reports:
Rapid melting of polar ice sheets may be due to short-lived natural events rather than climate change, scientists said.
New research suggests more time is needed to predict the likely impact of global warming and ice loss on sea levels.
The ice sheets covering Antarctica and Greenland contain more than 99 per cent of the world’s glacier ice. If they melted completely, the global sea level would rise a catastrophic 63 metres.
