"Are you suggesting that climate change (accepted by 99% of the world's scientific community) is somehow not real?"
Interestingly, in another post on the topic of rockets, specifically the Challenger disaster, someone posted that real engineers will only say they are certain if it's 100%. 99.5% only mean "probably". The poster was roundly upvoted for that comment.
FWIW I'm not denying climate change here, just pointing out the similarity in the numbers in two quite different situations and the different response to those numbers :-)
