Most people say they know the earth is round. But actually, that's not true. They don't KNOW the earth is round; they have faith in science that it is round, just as have faith in science about continental drift, dinosaurs and Relativity. Science is their faith. Unfortunately they scorn the faiths of others.  Similarly people have faith in climate science and no tolerance for others whose faith stands elsewhere.  Is this intolerance real, and is it religious in nature ?
