we just don t know how much. the scientists say that the level of the oceans is bound to go up, almost whatever we do, maybe by half a metre or so by the end of the century, if emissions are brought under control, but maybe by a metre if they aren t. and of course, that would be devastating for millions of people living on coastlines around the world. but they also can t rule out a much larger rise, approaching two metres. it all depends whether the polar ice sheets start collapsing. 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 disastrous. india is now in the grip of flooding. higher seas would make it worse. the science has never been so clear that we can head off the worst of climate change, but not all of it,
we just don t know how much. the scientists are warning that there is going to be some rise in sea level whatever we do, maybe half a metre by the end of the century if emissions are brought under control, or one metre if they are not 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 disastrous. india is now in the grip of flooding. high seas would make it worse. the science has never been so clear that we can head off the worst of climate change, but not all of it, so we urgently need to get ready. david shukman, bbc news. david shukman, bbc news.
