Argument: Better ways to fight global warming than geoengineering
- Debate: Geoengineering, solar shading - con argument.
Mike MacCracken, chief scientist for climate change projects at the Climate Institute in Washington DC, said in 2006: "If I'm going to put satellites in orbit, why not put energy generating satellites that capture solar energy and beam it down to Earth?. Rather than blasting sulphur into the stratosphere, why not invest in other kinds of energy systems, such as wind energy or ocean energy, that don't cause these kinds of problems? There's a lot to do well before you get to geoengineering."
