Your analogy with big tobacco is on point. Big oil and big tobacco share a strategy of promoting false skepticism, shifting blame to consumers, using the legal system to harass and intimidate scientists, and lobbying to get support from elected representatives. Big oil is of course bigger, and the entanglement with politics, jobs and other companies in the private sector is much stronger. These issues are widely documented, and the books that climate scientist Michael Mann wrote were eye opening to me. The only sensible exit is to legislate at scale. These companies will not self regulate. The lag between cause and effect makes this extremely dangerous. A heavy carbon tax is an obvious way to do it.
