A key task of the UN gathering, which kicked off on Nov 11 in Baku, Azerbaijan, is to establish a 2025-35 climate finance commitment from developed nations to developing countries, which is officially known as the New Collective Quantified Goal.

The next major United Nations meeting on climate change, known as COP29, is about to get underway in Baku, Azerbaijan. These annual meetings are the key international summits as the world attempts to address the unfolding climate crisis.

COPs have been getting progressively longer; the excellent team at Carbon Brief extrapolated the trend line, which suggests COP29 will end in the small hours of Sunday morning. Even that may be optimistic.
