Humans are incredibly bad at envisioning things on a large scale, especially something as (relatively) gradual as climate change.
I have hope that enough people in government are/will be making meaningful inroads with regard to climate change, but I don't think the public will get it until Florida and Louisiana have sunk into the Gulf.
I don't think it's climate scientists' fault; I think it's incredibly difficult for average people to grasp the big picture, mixed with contrarians and oil industry lobbying/propaganda working against those efforts.
