How hot will Earth get by 2100?
Climate scientists are studying a fresh set of socio-economic scenarios to model the future of the planet. The simulations range from optimistic worlds — in which governments join forces to advance low-carbon technologies — to bleak ones, with countries ramping up their use of cheap fossil fuels to pursue economic growth at any cost. The research could have a key role in the negotiations around a new set of commitments to reduce emissions. “We need these model results to give us insights into the impacts of our choices,” says environmental-health researcher Kristie Ebi. “This is not science fiction.”
