"Carbon Sequestration" is sometimes suggested as a parallel process alongside a significant shift away from carbon-producing technologies. The logic is straightforward: carbon dioxide is still produced, but rather than remaining concentrated in the atmosphere for a century, it is extracted. This extraction can take place at the point of production (so-called "carbon capture") or more generally, using CO2-loving plants. Although some may hope to use carbon sequestration as an excuse to delay or ignore a move towards non-carbon-emitting technologies, the reality is that the planet is close enough now to a potential climate tipping point that we should not rule out any effort that might help us forestall disaster
