Ashes Ashes

Episode 21 - "Clima Ex Machina" The global climate is in bad shape and quickly getting worse. The debate as to how or why is long over (from both data and irrelevance) and the conversation is now turning to "Well what now?" The IPCC has set down an ambitious plan to get us off our fossil fuel fix, but it involves a lot of unproven technologies to help us stay under 2C. Further, many researchers believe this won't be enough and are proposing their own megascale engineering projects to try and keep Earth from slowly cooking us. This week on Ashes Ashes we tackle the world of geoengineering, exploring what's realistic, what's likely, and just how much trouble are we really in.
