282RA...yes, it 'might' be that bad. It is NOT clear yet. *IF* islands & low areas start getting submerged, serious steps will have to be taken, and population reduction is one of the major ones. (we should have been doing it for years, already). Areas like Bangladesh simply can't deal with much sea-level rise, and India & Pakistan won't be in the mood to help...

On the other hand, Canada & Russia might gradually get warm enough to support more. If it gets bad, it WILL be at a rate higher that we'd like to deal with.....the lower we can get the population first, the better off we'll be.

I'm just speculating...there are people who do this all day long, and have better ideas of the details.
