I don't disagree that there are huge risks. I just don't think anyone is taking those potential massive risks seriously, and that includes a substantial number of environmentalists and the leaders of most of the world. Another thing that might cause change to actually happen is if we're "lucky" enough to get a "minor" catastrophe that totally changes global opinion but isn't anywhere near as massive as the stuff you're talking about.
