'It looks more likely with each day we burn fossil fuels': polar scientist on Antarctic tipping points

Despite working on polar science for the British Antarctic Survey for 20 years, Louise Sime finds the magnitude of potential sea-level rise hard to comprehendFor more than 20 years, Louise Sime has worked at the British Antarctic Survey specialising in polar climate dynamics. She uses ice cores to reconstruct past conditions and predict future changes. She now leads several international Earth modelling projects.Why are the Arctic and Antarctic regions important for the rest of the world?They are one of the pillars of global climate stability, a giant store of frozen water, an essential "biotic pump" that helps to store carbon, and an albedo shield that reflects much of the sun's light and heat back out to space.
