Have the glaciers of the mountains and the polar regions and we have the great ice sheets of greenland and antarctica. the mountains and polar glaziers are particularly sensitive and we have already committed to further melting over the next decade, to hundreds of years. we�*re also going to see more ice loss from the greenland ice sheet over this century. and for the antarctic ice sheet, there is a wide range of possibilities if we limit greenhouse gas emissions. we may be fortunate and have a relatively low contribution to sea—level rise. but if we have very high greenhouse gas emissions...

We just don't know how much. the scientists are warning that there's going to be some rise in sea level really whatever we do. maybe half a metre by the end of the century if emissions are brought under control, or a metre if they aren't. and that would be really devastating for millions of people on coastlines around the world. but they can't rule out a far bigger rise approaching two metres if the polar ice sheets collapse. the great ice sheets are already adding to the level of the sea, but this process may suddenly accelerate. scientists aren't sure, but the implications would be disastrou...

Area of expertise is the oceans and sea—level change, in fact he spent three years investigating this, haven�*t you? so it would be remiss of me not to find out more about that. what did you find exactly? that is right, we have over 200 authors in the whole report. we have looked at 111,000 scientific studies over three years and i work on ice sheets and sea—level rise, as you say. we don�*t do new research, we assess the robustness of the evidence. forthe assess the robustness of the evidence. for the antarctic ice sheet, we looked at the range of possibilities for the future of the i...
