Even if USA reversed 180 degrees, the rest of the world is going to continue fossil fuel usage. Developing nations will continue to increase individual CO2 usage as their economies improve. People want to live a modern western lifestyle, and that requires more energy. Realistically the world is going to generate far more energy, not reduce energy usage/production. Moving to solar and nuclear is the only likely solution that will result in reduced CO2 volume.
