If we have put too much CO2 into the air, wouldn't it make sense to find ways to remove it again? Well, yes: it would. But sadly it isn't likely to be easy or cheap and, according to new research, it isn't an adequate "solution" to the problems of climate change.
The possible "carbon removal" techniques are very diverse. They include growing trees on land or algae in the sea and capturing and burying some of the carbon they have taken from the atmosphere. There are also engineered solutions that "scrub" CO2 directly from the air, using chemical absorbents, and then recover, purify, compress and liquefy it, so that it can be buried deep underground. That sounds difficult and expensive, and at the moment, it is
let me know more about that !
