To climate scientists, climate change is not a question of belief, but rather one of physics. It's a physical reality that gases like water vapor and carbon dioxide absorb the radiation emitted by the Earth and in doing so trap energy in the atmosphere. It's physics that trapping energy in the atmosphere changes climate. Physics is simply physics, and whether you or I believe in it or not will have absolutely no impact on the outcome. I've never been asked if I believe in gravity, for example, yet like gravity, the absorbing of energy by greenhouse gases is a matter of physics and something humans cannot alter. Read more at
