- Under a new UN deal on climate change agreed to in Lima, Peru, every single country has agreed to submit a plan next year for addressing their greenhouse-gas emissions.
- That’s a first. Past climate deals only targeted the emissions of wealthier nations and exempted fast-growing countries like China and India.
- But there are huge caveats. The plans will all be voluntary — countries can promise to cut as much or as little as they want. And there’s no rigorous outside review. (The US wanted one, but this was opposed by China and India.)
- Experts warn this deal isn’t enough to prevent significant global warming: the world is still on pace for temperature increases of 3°C (5.4°F) or more by 2100. Which means how to adapt to warming has become an equally large part of these talks — especially for poor nations.
