What is interesting is how the tobacco industry laid out this whole template for the denialist movement, something that was adopted wholesale by others such as the sugar industry and, now, the oil industry.

It all devolves back to a deliberate muddying of the waters and obfuscation. Funding people to give you the conclusions you want so you can pretend that there is doubt where there is actually consensus.

There's also a template that applies to those who fall for it each time.
