Sequestering carbon using current methods requires too much energy. In order for CCS to work out we need a surplus of green energy, and we have a deficit. Geo-engineering could be done by changing the planet’s albedo, for example by seeding the upper atmosphere with certain chemicals, but on the one hand we don’t understand the earth’s climate system well enough to do this safely, and on the other hand it’s like having a foot on the gas and a foot on the brake at the same time, intuitively you can tell this isn’t a good solution.
