And thank you, Cantoperate, for making the point that logic and science fact are not the same as a personal opinion. I also strongly contest that linked report is full of plenty of words that are NOT suppositional at all. I could list the words and phrases here, but I realize that you would never interpret them as I do. According to your brief lexicon on "weasel words" I infer the following cognitive dissonances:

1. I "might" not be injured/killed in a car accident so I don't need a seatbelt.
2. I "may" not get sick so I don't need health insurance.
3. I "could" try Russian roulette as it's not certain I'll kill myself

...ad infinitum. 

While I respect your right to a dissenting opinion, I'm going to base my actions and beliefs on the overwhelming scientific evidence, and moral imperative, that the status quo is doing irreparable damage to our children's future.
