There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well-organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere.

A free press is the immune system of representative democracy.

You can say the Earth is flat, but it doesn't mean you're going to fall off the edge.

There is the natural tendency that all of us are vulnerable to, to deny unpleasant realities and to look for any excuse to push them away and resolve to think about them another day long in the future.

...it is appropriate to have an over representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis.

The truth is that climate change is presenting the greatest challenge humanity has ever faced.

Unless we stop dumping 70 million tons of global warming pollution into the atmosphere every 24 hours, which we are doing right now ... the continued acceleration of this pollution would destroy the future of human civilization.
