But this is a charged issue for many environmentalists and some scientists (including Jane Lubchenco, the new under secretary of commerce for oceans and atmosphere) who oppose such interventions with nature because they could produce unintended harms, falsely imply that we can engineer our way out of any problem or blunt efforts to cut emissions of greenhouse gases at the source.

That's ironic that you mention that particular property of CO2, because there are scientist that theorize that, since CO2 is heavier, the GCM models are not correct — most CO2 produced at Earth's surface NEVER gets well mixed in fact most CO2 gets removed by rainfall, or gets absorbed by plants or the ocean long before it can cause any change in the so - called Greenhouse gas effect (but the GHG theory is not correct anyway) and the fact that they have severly underestimated CO2 upweelinng from the dee
