Richer countries have pledged a record $300bn (£238bn) to help the developing world fight climate change, but the deal is facing recriminations that it comes nowhere near addressing poorer countries' challenges from global warming

The talks at the UN climate summit COP29 in Azerbaijan ran 33 hours late, and came within inches of collapse.

Developing nations, as well as countries that are particularly vulnerable to climate change, dramatically walked out of the talks on Saturday afternoon.

But at 03:00 local time on Sunday (23:00 GMT on Saturday), and after some changes to the agreement, nations finally passed the deal. It was met with cheers and applause, but a furious speech from India showed that intense frustration remained.

Then nations including Switzerland, Maldives, Canada and Australia protested that the language about reducing global use of fossil fuels was too weak.

Instead, that decision was postponed until the next climate talks in 2025.

There was also a commitment to tripling the money that goes towards preparing countries for climate change. Historically, only 40% of the funding available for climate change has gone towards this.

As well as the promise of $300bn (£238bn), nations agreed that $1.3tn is needed by 2035 to also help prevent climate change.

This year - which is now "virtually certain" to be the warmest on record - has been punctuated by intense heatwaves and deadly storms.
