In Praise of Climate Engineering

“Politicians and commentators are understandably pessimistic about the chances of an international deal on carbon cuts emerging from the United Nations summit in Mexico this December. … Despite all of the optimistic talk about wind, solar, geothermal, and other sustainable, non-carbon-emitting energy sources, no alternative is remotely ready to shoulder the energy burden currently borne by fossil fuels. This is why I have long urged policymakers to increase significantly the amount of money invested in research and development of green-energy alternatives. Now there is research that shows exactly how we can put this approach into action.”
