This solution entails reducing all emissions to zero with mandatory carbon traps on all energy generation and vehicles. Also there would be a switch from fossil fuels to cellulose fuels catalyzed by algae and bacteria. All plastics would be replaced with cellulose plastics. All this cellulose is mined directly from the atmosphere via giant, genetically engineered, fast growing trees or plants, which are then harvested for all fuel and plastic needs.
The net result should be rapid sequestration of carbon to go along with a lively economy. It would be important to bury our trash (made of the cellulose) into dumps. Also would be important to have measures to do controlled burns of these landfills, hundreds of years in the future, in case the cellulose economy begins to freeze our planet.
