HERE are the 100 reasons, released in a dossier issued by the European Foundation, why climate change is natural and not man-made:

1) There is “no real scientific proof” that the current warming is caused by the rise of greenhouse gases from man’s activity.

2) Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth during geological history...

Those two are really enough, if you need more read away.
