So we turn off power plants, stop manufacturing, and people all over the world stop driving, shipping, farming and flying with anything that emits C02. What do you suppose happens after that?

The US has been spending a couple hundred million dollars per day on the war in Afghanistan alone for the last 20 years. No one even noticed.

If the US put its mind to it (WWII levels of mobilization), it could probably achieve full renewable electrical conversion (all fossil fuel infrastructure obsoleted and removed) within five years or so.

There are 300 million people in the US, so "A couple hundred million dollars per day" is less than 1 dollar per person, per day. At $1 per person per day, it would take a lot of days to convert everyone to full renewable.
