If we don't avoid the climate change catastrophe, then current investments are going to be even less valuable than if we do. That's no argument for continuing to prop up those industries.
I have a feeling that the fossil-fuel investors, to the extent that they trouble their pretty heads about it at all, think that, so long as they make enough money now, they can just run really good air conditioning and it won't affect them. Idiots.
If we can spot these trends while working 9-5, then an idiot can probably spot them if they spend 40 hours a week on it.
