Seriously? 
Science is NEVER allowed to say the word; "PROVEN" even for a climate change end of the world? Are they also only 99% sure the planet isn't flat? 
36 MORE years of "could be" the end of the world will make CO2=Y2Kx1984/0

The price you evil climate blaming witch burners will pay for your fear mongering will be in your own children's history books.
Even Bush didn't threaten the lives of billions of innocent children with CO2 death threats.
Shame on all of you.
