Oh, why are you bothering? The facts are in: It's all a hoax started by China.

The deniers on here just cut & paste nonsense that they come across - most of which has been discredited long ago, or is meaningless to the subject at hand. There's a great article in the current Skeptical Inquirer magazine which puts a lot of these issues to rest and basically says we're all going to die really soon.

Now, I could cut & paste, or quote the article (which is filled with references) but, as Trevor Noah says: "Ain't no-one got time for that". Plus, I really don't care to waste my time trying to persuade somebody that their nonsense is just that.
