Adapting to the impacts of climate change—like heat waves, increased floods, and natural disasters—is an enormous challenge. It’s also one that comes with an enormous price tag. Although it’s difficult to calculate the extent of the costs, the World Bank estimates that developing countries need $70 to $100 billion USD per year through 2050 to meet their current and future climate adaptation needs.
The Climate Policy Initiative, however, estimates that in 2011, only $4.4 billion USD in adaptation finance went to developing countries. This leaves a gap of anywhere from $65.6 to $95.6 billion USD per year between what developing countries need and what developed nations are giving.
So who can help fill this gap?
