The Kyoto Protocol – an international climate treaty – expires in the year 2012. In March 2009, scientists met to prepare policy recommendations for a new treaty – to be created in Copenhagen in December 2009. One issue they discussed was geoengineering — intentionally altering the climate.

The only realistic way to actually reduce temperatures on this planet, this century, is for us to intentionally interfere with the climate system. He's a proponent of conducting scientific research to find ways to turn down the global thermostat through technology. This would work to cool the Earth because volcanoes do this, and we know that volcanoes cool the Earth. Caldeira admits this approach could have unforeseen consequences. So I think it's imperative that we do the research now so that we learn what we can and can't do, and then put it on the shelf and hope we don't have to use it.
