BBC NEWS | Science/Nature | Branson launches $25m climate bid

BBC NEWS | Science/Nature | Branson launches $25m climate bid:
They are looking for a method that will remove at least one billion tonnes of carbon per year from the atmosphere.
I wonder how large a pile of diamonds that would be?

Other scientists are also looking at schemes that might "scrub" the air of CO2, collecting the gas for safe storage; but many critics say the energy required to achieve this would make such an approach self-defeating.
Nonsense. It depends entirely on the source of that energy. This criticism assumes a fossil source, but there are others.
