Coastal Currents: Geoengineering Omnibus

At the end of "An Inconvenient Truth," Al Gore suggested we have about 10 years to make dramatic cuts in global carbon pollution before things get really freaky. That was seven years ago. 

We're running out of time. Climate Change is happening. With little-to-no mention of it during the presidential debates and developing nations putting yet more coal-fired power plants online, we're behind the eight-ball. 

So how do we fix this? Some have suggested that we deploy some planet-wide emergency measures to buy us enough time to scale up sustainable energy, increase efficiency, and improve harmful agricultural practice. From painting our roofs white to building a giant space mirror, geoengineers study admittedly risky short-term climate solutions. 

The field isn't without controversy, and humans have a checkered past when it comes to tinkering with large-scale ecology. So while 99% of efforts should be focused on carbon reduction, these scientists are working on some climate hail-mary passes.

Today on Coastal Currents, we talk with Ken Caldeira, a climate scientist working for the Carnegie Institution Department of Global Ecology at Stanford University.

He investigates issues related to climate, carbon, and energy systems. His primary tools are climate and the carbon cycle models, although he does field work related to ocean acidification.
