The process has already started. We must re-start the stalled climate change negotiations as a first step towards the deep cuts in emissions from factories, power stations, cars and homes, needed to curb damaging climate change.

Sea levels could also rise by tens of centimetres, threatening millions of people in low-lying countries.
