So yes, the fact that it's all on purpose also connects to how, given the choice, the fascist would rather create a system that ensures mass death for probably most of the world (which they favour for people who don't look like them) than risk the "chaos" required to maybe save life on Earth.

And of course, fascist politics is the politics of "order" uber alles and "order" par excellence at the same time. That's quite obviously at the root of all fascist violence, designed to extinguish "chaos" of heterogeneity, the Other and the wild.

In a way it sort of does come back to "order" and "chaos". For the order prized by fascists, conservatives, and liberals alike, the kind of changes really needed to save us all really do amount to "chaos", because the order that they are trying to preserve can't continue if we all want to survive.

By contrast, conservatives and liberals cover their ears either way, believing that the order of their preferred way of life is in no real danger, either because there is no problem or that, with the power of "progress" (usually meaning minor regulatory changes or technofixes) will save the planet.

Like standard conservatives or, hell, liberals, fascists, including white nationalists, are people who value the continuity of order, or that of a certain idea of civilisation, above the continuity of life on Earth as we know it. The difference is that fascists are actually conscious of this choice.

I think white nationalists and other fascists are aware of this too, and view the changes that may be required as incompatible with their political desires, since they entail that the order they deem to be "natural" to humans, the basis of their preferred ways of life, might not be able to continue.

Of course, you also can't separate this from the fact that to even attempt to "reverse" or at this point even just mitigate the effects of man-made climate change is going to require, in broad terms, massive social restructuring and fundamental changes for the societies we live in around the world.

They know what's happening, they know they can't really deny it, and they've decided that their answer is ethno-nationalism as a means of preserving white hegemony and "prosperity" through global genocide.

And of course, this agenda is inseparable from ethno-nationalism, or rather white nationalism. In fact, you have to understand this as a fascist white nationalist response to the reality of man-made climate change, rather than simply the attempt to deny or erase it.

They know man-made climate change, at its current pace, would render several parts of the world, inhabited by millions of people of colour, uninhabitable, and so the agenda is to make it impossible for them to migrate and thus ensure racialised mass death. It would be genocide at global scale.
