This is more bent science because they didn’t consider the 3rd purpose of dams (irrigation, power and flood control).
All rivers are prone to flooding. Did they consider the methane release from destroyed vegetation and animals from regular uncontrolled flooding. Of course not.
I’m betting it would be a wash, only with dams you would at least get the economic benefits of irrigation, power and flood control. WSU is seriously in the grips of agenda driven science.
If you read the source material, this garbage is aimed at preventing developing countries from building dams.
