Adapting to climate change is just as much of a priority as stopping it. As such, preparing for global warming is a big business that countries can capitalize on in the coming decades. Relocating populations and building new housing projects means transportation and construction will boom for the foreseeable future as humans adapt to the changing climate.
No, increasing UN Annex I aid for climate change adaptation is not a priority that requires greater focus/funding, because combating climate change comes at too great of cost. There are many other issues that the United Nations should focus on, rather than climate change, such as basic human rights. Spending on immediate social need is more important that providing incentives for climate change.
