[Q] What do you say to those who deny climate change?
You simply can't deny it. What you can do, although it is misguided, is to deny how much we have been responsible for it. But the climate is changing, and if it goes on changing, we are going to be in trouble. Everything we can do to reduce the danger must be done, otherwise great cities are going to be submerged. It's absurd to pretend otherwise.
