Your maintenance guy says your house "might" have termites; you buy them a piano.Deniers do not believe 30 years of science NEVER agreeing it WILL happen and nothing beyond just "could be" a crisis is good enough to condemn our children to a CO2 hell on Earth but believers say "maybe" is ok to goose step their own children into their exaggerated greenhouse gas ovens.
You fear mongers make neocons look good.
Your doctor says he's found something that could be cancer; you drink morewhiskey.
Your mechanic says you may have a bad water pump; you take a 700 mile trip.
Deniers fail to understand the English language.
