Unlike you, I'm not 100% sure what is what, so won't quote anything as gospel, just yet. I don't spout rumours as facts until I see some proper evidence. Cartoons of polar bears drowining does not constitute evidence, in my book. Neither does Al Gore.

Boon Mee's graphs have a lot more credibility.
