Dangerous changes in climate have already begun. If the world continues on its current trajectory, global temperatures will eventually rise by several degrees centigrade, causing higher sea levels, mega-storms, severe heat waves, massive crop failures, extreme droughts, heavy flooding, and a sharp loss of biodiversity.
危险的气候变化已经开始显露迹象。如果世界继续沿着目前的轨道前行，全球气温终将上升几摄氏度，进而导致海平面升高、特大风暴、严重热浪，大规模农作物歉收、极端干旱、严重洪涝和生物多样性骤降。
