> Governments alone cannot hit those targets. Private businesses will need to reallocate capital for low-carbon investments and find ways to make large-scale emission reductions possible. Then governments - well, at least the USA as it is responsible for a disproportionate amount of emissions - should stop subsidizing (e.g., Big Oil) and protecting (e.g., factory animal farming) the dirty behaviours, and shift those efforts and resources to the cleaner behaviors. But this means ignoring a lot of influence (e.g., PACs, etc.), as well as tradition. In short, if the climate is going to revert, the governments need to change. So much for optimism.
