If the fossil fuel companies truly believed that the benefits of fossil fuels outweighed the negative effect of manmade global warming then they could use their waste resource to communicate that. Instead they used deceptive tactics. Like for example creating groups that falsely claimed to be grassroots organization that opposed policies on climate change and renewable energy. The fossil fuel companies even sent forged letters claiming to be from actual nonprofit groups to members of Congress to influence votes on federal climate change legislation.

Also, it’s very telling that the fossil fuel companies after several decades haven’t been able to come up to alternative scientific findings . That instead the fossil fuel companies now have to acknowledge the IPCC findings and the need to act against manmade global warming.

The fossil fuel companies’ deceptive tactic has also have had huge negative effect on our societies. Because they contributed to halt earlier action on climate change that could have made the transition away from fossil fuel much easier. Just like the paint companies massive spending on PR, marketing and lobbying made it possible to sell lead paint in USA decades after the negative effects was know leading to huge costs for society.
It is not just the fossil fuel companies who believe the benefits outweigh the negative effects, but
almost anyone who looks at the science.
The oil companies and many others tried to communicate that the science was not settled, and that the uncertainty was very high.
Anyone who voiced the idea that our use of fossil fuels may not lead to catastrophic consequences, was shouted down,
labeled a denier, or even a heretic. (The use of the term heretic for Dr. Judith Curry, says quite a bit.)
You say the fossil fuel companies haven’t been able to come up to alternative scientific findings,
to which I would ask alternative to what? What scientific finding do you think we have?
Yes the oil companies acknowledge that the science portion of the IPCC is correct, because it is,
but the science portion, is only that CO2 is a greenhouse gas.
The predicted catastrophic warming, is not directly from the added CO2, but from the predicted amplified feedbacks,
which have not been validated at the levels necessary for concern.
The IPCC says the ECS from doubling the CO2 level could be as low as 1.5 C.
(They also say the ECS could be as high as 4.5 C.)
The range between those two is the uncertainty.
Scientist, some of whom were lead authors on the last IPCC report, looked at how our climate has responded
to warming in the past. They found a most likely ECS of 2 C, (This finding strangely did not make it into the IPCC report.)
