Climate adaptation efforts could be far more valuable than previously thought

The world is getting its climate sums wrong - and it could be costing us all. The value of investing in climate adaptation is usually measured according to one metric: the value of the climate losses it prevents. But that leads to huge underestimates of its true value, according to research by the World Resources Institute – because when the social, economic and environmental benefits of climate adaptation are taken into account, every $1 invested returns $10.50 over a 10-year period.
