UN urges countries to prioritize climate crisis over national interests at COP28.

The UN's top climate official has warned that the world is at a "tipping point" in the climate crisis that requires all countries to put aside their national interests to fight for the common good. He urged countries to put aside their differences and forge a "course correction" that would put the world on track to meet the aspirations of the 2015 Paris climate agreement and limit global heating to 1.5C. The Bonn conference, a preparatory meeting intended to lay the technical groundwork for the much bigger Cop28 summit that starts in November, opened amid long-simmering contentions.
