If it was never about economics, why the desperation to argue against economic impacts?
If it’s incompletely incorrect, and you aren’t using that against climate change, then your point is rather moot. Also, again with the climate has changed because of nature comments, so in which case, we can observe the evidence for which natural climate forcing variable is causing it, right? Or, it’s all random chance and energy is coming from nowhere, which is scientifically impossible. Either way, your argument is baseless.
