Good. The sooner all fairy stories religion is banned, the better.
How tolerant. 
There's a lot more proof to support global warming than gods of any description.
The two cannot be compared. The existence of a deity can neither be proved nor disproved scientifically. That's why religion is described as a faith.
Equally, atheism is a faith. Agnosticism could be described as scepticism.
The problem I have is that banning religions, were it ever to be attempted, would be a totalitarian move -destined to failure and a cause of much suffering. I am happy to tolerate the existence of people who live their lives by their own faith. I do not tolerate the imposition of faith, nor any attempt by one faith to oust another (which is effectively a way of "banning" the latter).
As far as global warming is concerned, it is a question of atmospheric physics which, given time, will be answered scientifically.
