In the identical approach, there are two main issues we have to do to handle local weather change. We have to lower emissions—for instance, by slowing down our use of fossil fuels. That’s akin to turning off the water faucet. Then we’ll must mop up the spill—that’s carbon removing, processes that goal to tug carbon air pollution out of the environment.

However there are questions too, and a brand new research lays out some issues with seaweed farming, one commonly-suggested approach for ocean-based carbon removing.

Carbon removing has develop into an important piece of our response to local weather change, because the UN’s local weather change committee identified in a report final 12 months. Estimates of precisely how a lot carbon we’ll must take away fluctuate, however the consensus is that it might want to high a billion tons yearly throughout the subsequent few a long time if we’re going to maintain warming under 2 °C over preindustrial ranges and keep away from the worst results of local weather change.
