Promising Climate Change Denial quotations
So we are left with a stark choice: allow climate disruption to change everything about our world, or change pretty much everything about our economy to avoid that fate. But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us.

I don't believe that climate-change fiction will change the mind of a denier because most of the deniers I've met are basically in a cult situation. It's a faith issue. It's not a rational issue. There's no fact that's going to change their mind. They simply believe in the cult of climate-change denial and it somehow feeds into the rest of the mythos of their own life story.

By looking the other way on climate change we facilitate a collective denial, and we do it for each other.

The science [of global warming] is beyond dispute.
