OR, they know climate change is happening but think their money will save them (which it just might) when the s*** really hits the fan.
Agree. With money, you can always move if your area is becoming uninhabitable, and you can always find water. The ones who will be most affected are the poor and the wildlife, followed by the middle classes, and least, the wealthy.
I read an interesting speculation a couple of years back wondering if the ignoring of warnings was only short-sighted greed, or something more, the argument being that even these people have grandchildren and that it was difficult to understand why that didn't matter to them. It was wondered whether there might be a motive to allow this to happen deliberately, not too difficult to imagine in a world that so many seem to want to destroy. Who would benefit and how?
We can ask the same about organized COVID vaccine disinformation - does anyone benefit from that? If so, one needs to consider malice as well as stupidity in that arena as well. They say to not attribute to malice what can be explained by stupidity, but there is so much malice in the world now, it's reasonable to consider.
It was suggested that climate change would impact emerging nations like Mexico and India harder than the first world Western democracies, which are threatening to assume a prominent role on the world stage and challenge more mature economies, and that this might be an incentive to promote global catastrophe.
Or, somebody might see this as a way to thin the herd - instant population control in a world where increasing numbers of people competing for a finite number of resources will lead to political instability on a global scale.
Whether there is any merit to either of those ideas is difficult to judge. Or whether this is deliberate or just poor planning. I'm not sure that it matters except that in the case of the former, the expected damage would be greater. But in either case, the wealthy will have it better, and might not see global chaos and suffering as a negative.
