However, there's 2 huge problems with that. First, stopping CO2 additions at this point will just cause a marginal delay in the progress of global warming.
Second adding CO2 will stop. Fossil fuels are finite and will stop this century. All regulation can hope to do is stop it a bit faster. A few decades at best. Which just doesn't matter. Plus oil producing countries, the only ones that have any hope of doing this will never cooperate.
Even nuclear winter will pause global warming, but it won't work to prevent it's consequences, because of water. So will any other mechanism that lowers temperatures.
I'm not saying there aren't other advantages to ecological policy, but stopping global warming just isn't one of them.
Global warming cannot be stopped by regulation. It cannot be stopped by humans at all. That's what the IPCC models say. We need to adapt to it. That means moving billions of people, frankly, out of the way. At an extremely high level what needs to happen is that billions of people need to be moved a LOT closer to a coastline.
