For a long time, rich countries like the United States and Europe have been the biggest contributors to global warming. But that's changing fast. China, with its rapid economic growth and massive use of coal, is quickly catching up. Last year, China even surpassed Europe in total historical emissions. This shift is changing the way we think about who's responsible for climate change.

China now emits more greenhouse gases each year than any other country. It's building renewable energy, but it's still adding a lot of coal power. The old rules say rich countries should pay for the damage caused by climate change. But now, countries like the U. S. and the European Union want China to help out too. China says it's already doing its part, but others aren't so sure.

It's not just about who's emitting the most. Some countries, like Saudi Arabia and Qatar, have very high emissions per person. And poor countries like India want more time to develop before they have to cut back on fossil fuels. Figuring out who should pay for climate damages is a big debate at the global climate summit in Baku.

Experts think it won't be easy to agree on how much money poor countries need and where it should come from. There's a lot of tension between rich and poor countries, and between big and small emitters of greenhouse gases. The outcome of this meeting could shape how the world works together to fight climate change.
