Unless someone invents s technology that can scrub 100M metric tons of green house gases from the upper atmosphere, there is no chance of stopping what has been set into motion. I also think it’s going to accelerate much faster than any of the models predict. My brother is a climatologist and he’s been telling me I’m nuts for years, over the holidays he told me that he now thinks I’m right, and he’s scared for the future of his grand children.
Technologically, that's probably not true. Thatcher, for example raised alarms in the political/public sphere based on advice from government scientists in the late '80's IIRC. A lot could have been done in the last 30 years.
Politically/sociologically though, you're probably right. Views on economic growth, the nature of the good life for humans, the relationship between the real ('nature') and virtual ('economy') worlds, public and private goods, etc, had all become sclerotic & fixed as invisible myths by that time.
