There are really two kinds of greens: science-based types that are interested in practical solutions and understand engineering, and anti-technology or even anti-civilization types that want to use the issue to force de-industrialization and de-development. Solutions are not what the second group wants. A solution would eliminate the problem as a political and social lever. The latter are louder because crackpots are always the loudest. That principle holds everywhere in politics.
