Thank you for that article. I shall read it in depth later, but a cursory glance suggests that Mr Thiel believes, as many do, that freedom means not being compelled to help his fellow humans, or even his own immediate society, by taxation or any other means.
The article also has a very alarming quote:
"The fate of our world may depend on the effort of a single person who builds or propagates the machinery of freedom that makes the world safe for capitalism."
What happened to making the world safe for people?
Nothing in that post explains why Thiel is a climate change denier. The only thing I see that could be construed that way is that he said it hasn't gotten warmer the last 15 years. It depends on when Thiel made that statement whether it was true or not at the time. The warming that occurred over the last year meant that there was statistically significant warming, but before about February the warming over the last 15 years was not statistically significant.
At worst getting the facts wrong by a few months doesn't make Thiel a climate change denier.
What's with posting links with a timestamp skipping the overall context?
Yeah, watch from t=0 the whole 3 minutes and 42 seconds. I don't hear anything shocking. It's not so much a rebuke of climate change, it's a rebuke of political correctness and the inability to have a debate.
