Can we save the planet...

...by making more CO2.

This counterintuitive approach is the idea that we should pull methane out of the atmosphere in areas where it is concentrated (such as landfills and dairy farms) and turn it into CO2 and release it.

But wait, CO2 is bad.

Yes, it is, but it's not nearly as bad as methane. So, it's possibly a tool in the playbook.
