Whether they are aware some think they may be overstated or not, I don't know. I do know it could not possibly be less relevant.

The study also shows that, if all conservatively estimated available fossil fuels were to be burnt, two to three times more CO2 than allowed for the 2°C target would be emitted. This only takes into account the fuels which are already known and which are economically viable to extract. The fossil fuels will therefore not run out before the maximum CO2 emission calculated by scientists is reached.

The above quote means that even if we only have between 1/2 and 1/3 of the FFs generally thought to exist, we still can't burn them all.

There are so many holes in this line of thinking about FFs and climate it's tiresome to have to repeat them to so many posters.

By the way, calling it a likelihood there are far fewer FFs than generally stated because a couple studies posited the thought is a stretch, and certainly not a scientific statement. Given there is far less certainty surrounding coal reserves than oil reserves, and there are large arguments about oil reserves, I'd think you'd be more careful about declaring their "likely" amounts.
