Why was this downvoted? The 28 times figure only applies if you average for when the activity continues for 100 years. Meaning if we stop and most of the warming is in the first 10 years, we'd see a huge global cooling from stopping such a massive effect. This would serve as a great way to quickly reverse global climate change once it gets critical, and once it get critical people can no longer say that it isn't a problem so you'd have the whole world on your side, so not sure why we would waste that opportunity by using it now rather than when the whole world understands the problem?
