Some people think that carbon capture systems are the way to solve climate change (and yes, I recognise that not everyone thinks that carbon is even a problem to be solved)
Historically speaking, the most effective carbon capture in nature seems to me to have been sedimentary rock in the form of carbonates. At one point in the Archaean period, the earth was apparently at like 22 bar of CO2, and the period right before the oxygen catastrophe would have had much of that carbon being locked up in rock, and much of the oxygen getting sucked up by sinks like the plains of iron that were suddenly rusting.
Honestly, the oxygen catastrophe should be on of the most important geological events in human history, and something we should teach to every schoolchild. Besides changing the atmosphere into something made up of mostly oxygen, the oxygen catastrophe also caused a global ice age. Between the two, the earth saw over 90% of its life die out.
Sort of a warning in that, I think -- if we're not careful playing God we could wipe out most life on Earth...
