Listening to James Hansen on Climate Change, Thirty Years Ago and Now

A possible answer, which seems to be the one that Hansen himself, at least in part, subscribes to, is that scientists are to blame."

I don't believe this for a second and blaming scientists for not being clear enough instead of the massive amount of misdirection, misinformation, and flat-out denial pushed in the interest of greed is downright insulting.

How can this be? Because those that stood to lose money paid boatloads to convince people that scientists are wrong, to secure politicians' votes via donation, and to generally profit off of the resulting lack of action and coming catastrophe.

I don't understand how they can say this? https://nsidc.org/data/seaice_index/
