Not to be a bummer but by far the most likely outcome here is that we don’t currently have a room temperature super-conductor, we never pull a consequential amount of carbon out of the atmosphere, and we don’t get significantly workable sustainable fusion in a timeframe that makes a difference.

You’d need a bunch of jackpots to come up, in a row, immediately, at this point for technology to provide a way out of the current debacle.

To paraphrase Paul Lieberstein’s character on the Newsroom:

If we stop drilling globally right this second

AND

Everyone stops driving their car and starts biking everywhere

AND

We invest immediately in clean renewable energy

THEN

I still don’t see a way out of this.
