I don't see what need there is to take the carbon out of the air. We spent 150 years of hard work getting all that sequestered carbon back into the biosphere.
Don't these people realize the climate of the Earth was most stable during the time of the dinosaurs? Our planet went for hundreds of millions of years with no ice ages and there was 1000 times more biomatter in the biosystem than there is today with 1000s more species. If people want to take the carbon back out, all they need to do is send another comet into Earth's atmosphere. If I had my way, we would double carbon production in hopes of putting a permanent end to the present Ice Age. Dave
