"We discuss some of the central issues: Is the climate crisis so far gone that we need to consider risky ideas like solar engineering? Is solar engineering a hubristic dream of techno-elitists or the best tool we have to reduce the impacts of a warming climate for millions of people in the developing world? Who would be the winners and losers in a geoengineered world?" LINK
