LOL, you guys are hilarious. Scientists can't even decide what killed off the dinosaurs even though there's overwhelming evidence to support either side. Now all of a sudden, a 'study' proves it can't be just the sun causing 'climate change', it HAS to be man.
It's not about denying the changing climate guys, it's admitting that Earth's climate is in CONSTANT CHANGE (there's even an arguement that is in fact what may have killed the dinosaurs and NOT an impact event).
The mere fact that scientists can argue both sides of an issue and not come to a unanymous agreement dictates my skepticism on this 'climate change study'.
Compare it to this; you may deny the existance of God, as I do, there's very little hard facts to support His existance, but then again that would mean over 3 billion people are wrong.
