You're right. We need two things. One is carbon-sinks. This can be done by permanent new trees. Or by replacing trees and use the old wood or plastics for buildings. Or make carbon based usables and permenantly bury their waste in deep landfils that don't let out co2. Or by new techniques for sequestering carbon from air. Planting trees and letting them die is only temporary. Second and most important though is getting more heat out of the planet than in. Focusing on carbon is one thing. But reflecting energy to space also works, e.g. by white roofs, or mirrors, or heat conducting materials that send off energy in frequencies not absorbed by clouds and co2/water/methane.
