Scientists use salt marshes to analyse global sea-level rise, 08 May 2013 11:49

The world's salt marshes could hold the key to predicting future sea levels after scientists used them to pinpoint when recent rises began. Scientists analysed sediments and fossils buried in salt marshes which show the recent rise in global sea levels – posing a threat to millions of coastal homes worldwide – began around a century ago. Professor Roland Gehrels, from Plymouth University, and Professor Philip Woodworth, of the National Oceanography Centre in Liverpool, say this can be linked to the general rise in temperatures and supports theories that global warming is melting Arctic ice caps and glaciers and impacting on sea levels across the globe.
