(Reuters) - Climate change is already disrupting billions of lives and humanity is not doing enough to limit the suffering, the United Nations climate science panel warned in a major report on Monday.
Noting that nearly half the world's population was already vulnerable to increasingly dangerous climate impacts, the report calls for drastic action on a huge scale: A third to a half of the planet needs to be conserved to ensure future food and freshwater supplies. Coastal cities need plans to keep people safe from storms and rising seas. And more.
