Episode 368 Scientists are concerned by a sudden increase in the rate of sea level rise. In 2012 it suddenly accelerated and has remained high ever since. From melting glaciers to oceans expanding as they warm, global sea levels have risen by more than 0.2 metres over the past 15 years. Places like Venice and New Orleans are already under threat - and this fast pace of change is only set to make things worse. So what’s causing this sudden shift? As sea level rise is now moving faster than we expect, is there something else driving up the tides? We also look to the future, when we could face truly catastrophic change.  Rowan Hooper and Penny Sarchet are joined by New Scientist climate reporter Michael le Page to discuss the latest research.
