Stopping emissions growth represents the most minimal of do-something responses.

Countries that innovate first get the new jobs, developing an economic edge over the C-free laggards that end up having to later import the technology.

The real focus needs to be on political action to stop this runaway train, real soon.

Unless we redesign our civilization in numerous ways, all of the science in the world won't save us.
