Ashes Ashes is a podcast about the end of the world. Each week we explore a new systemic or apocalyptic issue that society is facing now or will have to deal with in the coming decades. Through this we hope to draw the listener to the conclusion that our overarching economic and political systems are inherently flawed. Once that fact is accepted, it's that much easier to do something about it. Find episodes, full transcripts, links, and more at https://ashesashes.org.

episode 21: Clima Ex Machina
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.
