As detailed in the Lancet Countdown on health and climate change,1 the risks of climate change for human health are profound, and internationally coordinated efforts (eg, the UN Framework Convention on Climate Change [UNFCCC]) are essential to the response. The most noteworthy outcome of the 27th session of the Conference of the Parties of the UNFCCC (COP27), held in November, 2022, was the commitment to addressing loss and damage associated with climate change. Specifically, direction was given to address disproportionate losses and damages incurred to “the most vulnerable populations and the ecosystems on which they depend”.2 This work will commence in 2023, by identifying “priority gaps for which solutions should be explored”2 and the funding mechanisms to support those solutions.2,3
