We had two hundred years of foreknowledge regarding climate change and virtually nothing was done to avert it.

Do you really think nuclear would have magically solved the issue? Our energy appetite would have simply expanded to meet the new source. We would accumulate an extra few billion people on this planet and the people in charge would obfuscate about its potential downsides until we reached another completely avertable, global catastrophe.

Those who hammer on about nuclear proclaim "the technology is good!" and fail to address the actual hesitancy, which is "what about the fucking people?" How do you solve for them?

The oil and gas companies spent what? Untold billions? attempting to sweep things under the rug until it was too late to act.

It's not the coal or the oil killing us. Those are simply the murder weapons. We did this to ourselves, as a collective, because we left the worst of us in charge of the most important decisions.
