The COP29 summit in Azerbaijan has reached an agreement to provide at least $1.3 trillion annually through 2035 to poorer countries to help them fight climate change, with at least $300 billion to come from mainly industrialized nations.

Countries agreed on a deal to inject at least $300 billion annually in humanity's fight against climate change, aimed at helping poor nations cope with the ravages of global warming at tense United Nations climate talks in the city where industry first tapped oil.

Some hailed it as a good step forward, but delegates from poorer countries said it wasn’t enough to help them meet their goals.
