There’s the rub. First we would have to keep the warming from increasing. A reversal might be desirable but realistically that isn’t practical even if all fossil fuel burning ceased in the next ten years. Even if we prevent it from getting worse (stabilize) there will be consequences ie. additional arctic meltdown, coastal flooding etc. etc. Focus Fusion along with other nuclear/green solutions can help and ultimately reverse global warming. However we may have to employ what Werner Von Braun called Planetary Engineering (Geoengineering) (Wikipedia) until they can have an impact.
