Beginning this week, leaders from more than 190 countries will gather in Dubai for COP28, the annual climate global summit. This year, the stakes have never been higher: wildfires in Maui, partly exacerbated by drought, killed at least 100 people and resulted in $5.5 billion in damages. Flooding in Libya caused by extreme precipitation killed almost 4,000 people. Canadian wildfires blanketed North American skies. Massive sums of money are needed to address these and other disasters and to prepare for what's on the horizon. Enter the need for climate finance: money from public, private and other sources directed to developing countries to help them adapt to climate impacts and reduce their carbon emissions.
