Imagine yourself in their shoes. You have been trying to bring to attention the adverse effects of fossil fuels to the planet. And you are doing this using scientific methods and getting them peer reviewed. And you have built models that, in hindsight, are as accurate as possible.

And what reception you get for this? A large apparatus is deployed to label your work as pseudo-science. Your credibility is questioned.

In that light, those 4 words, "We are excellent scientists!" is profound. It contains within it the struggle, suffering, pain, integrity and pride of the experience they have gone through for many decades.

This reminded me of Clair Cameron Patterson [0] and his struggle to bring to light the effect of lead in gasoline. Cosmos' "The Clean Room" [1] is an accessible view on this subject.

Why is this downvoted? If you watch the video it's the outstanding quote from the entire clip. They predicted everything accurately!
