Nice list of the headliners.
But these people are all politicians. What could they possibly know about the atmosphere and how to manage the amount of carbon dioxide in the atmosphere? (Not that it would actually matter. There is very little of it and trees and crops just love it.)
But where are the scientists and technical wizards who are working to suck all that extra CO2 out of the atmosphere?
I would like them to speak out if no other reason than to reassure us that they wont take it all. That would really hurt the farmers and we would all ultimately starve to death.
There's no danger of that. The most effective methods are fossil, so they basically remove what they are adding. Second most effective is artificial photosynthesis. But covering the entire planet with that would not make a big difference. Yes, it would be more efficient than native plants for removal of CO2, but not a lot more.
The only time you need to worry is if they propose a new unlimited power source like fusion and they harness it to remove ambient CO2. But we are a long way from that happening.
