Wormley, read the article before you post,
this one says there is NO RELATIONSHIP, NO EVIDENENCE of Global Worming.

It has become increasingly obvious the spamming shit head does not
read the articles before he cut and pastes them.

Oh no, not MORE tipping points!!

Here a tipping point, there a tipping point, everywhere a tipping point,
you worthless piece of shit spamming ass hole.
