In March 2009, scientists met to prepare policy recommendations for a new treaty to be created in Copenhagen in December 2009. The only realistic way to actually reduce temperatures on this planet, this century, is for us to intentionally interfere with the climate system. Caldeira told EarthSky that humans might have already failed at cutting emissions in time to prevent a climate crisis. He’s a proponent of conducting scientific research to find ways to turn down the global thermostat through technology. We could do this by putting dust in the stratosphere. 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.
