By Agence-France Presse, The Guardian. For GSS Climate Change chapter 8. Excerpt: Thermal expansion of the oceans as they warm is likely to be twice as large as previously thought, according to German researchers. ...The findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, suggest that increasingly severe storm surges could be anticipated as a result. Sea level can mount due to two factors – melting ice and the thermal expansion of water as it warms. Until now, researchers have believed the oceans rose between 0.7 to 1mm per year due to thermal expansion. But a fresh look at the latest satellite data from 2002 to 2014 shows the seas are expanding about 1.4mm a year, said the study. ...The overall sea level rise rate is about 2.74mm per year, combining both thermal expansion and melting ice....  http://www.theguardian.com/environment/2016/jan/26/sea-level-rise-from-ocean-warming-underestimated-scientists-say
