A contentious climate summit has resulted in a $300 billion deal, with representatives from endangered island nations expressing frustration over the lack of substantial support from wealthier countries like the U.S., China, U.K., and Australia. The proposal includes a call for rich nations to contribute $250 billion annually to assist poorer countries, amid uncertainties about financing commitments, especially with a potential shift in U.S. leadership. Meanwhile, a coalition of countries, including the EU, Canada, and Mexico, is moving forward with ambitious greenhouse gas reduction targets by 2035, despite the challenges faced at COP29.
