Contesting the science of climate change is a line of defense for people who think they have a lot to lose if society takes climate change seriously.
Many Bitcoiners think they have something to lose. They don’t. Discussions about the implications of carbon transfer from mineral sinks to atmospheric gasses will lead to the use of more renewable sources for mining… more economic mining… a greater hash rate… and a more bulletproof network. Mining will always move to more economical energy options… which will end up being more carbon-neutral options. Miners know that, but they push back on policies that encourage this movement. This is an appreciation of the nature of Bitcoin mixed with a self-serving hope that Bitcoin’s incentive structure will somehow act differently.
