Jed, I meant $1 billion dollars for the prize! Also the challenge is to come
up with a way of REMOVING millions of tonnes of CO2 from the atmosphere, not
just ways to put less of it in...
JR <<The best method to "pump" CO2 out of the air is obvious, in any case.
You reforest large areas of formerly verdant land. >>
This is true in the tropics but the further North or South one goes, the
less global cooling results because of the albedo effect.. Planting more
forest in, say, Canada, can
actually be a source of global warming - see

impacts"
