Antarctic sea-level rising faster than global rate
Southampton, UK (SPX) Sep 01, 2014
A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2cm more than the global average of 6cm. Researchers at the University of Southampton detected the rapid rise in sea-level by studying satellite scans of a region that spans more than a million square kilometres. The melting of the Antarctic ice sheet and the thinning of floating ice shelves has contributed an excess of around ... read more
