Global warming is true.
And the world is flat.
All intellectuals know this as FACT.
The amusing thing about all the 'flat world' comments is that the idea of belief in a flat world was born in 1833!
there is not a shred of evidence that any of the ancients ever held such a belief. (which is logical, since anyone that has ever stood on a mountain, or looked over the ocean can plainly see that we live on a sphere)
