Well, I was a teenager at the time. I suspect I got some
   misinformation along the way.

   "See that big hole? Yup. We caused that hole".
   Then "Oh wait, no we didn't - it's a cycle"
   and along the way, "Scientists overestimate problem - sky is not
   falling".

   I was in elementary/middle school at the time. Back and forth
   and back and forth I'd hear conflicting reports.

   Just found this:

   and I'm starting to see where my skepticism comes from.
   Authoritative declarations shifting, one teacher one year says
   one thing, another teacher another year says another, the news
   floundering all over the place... and my science textbook would
   say one thing one year, something else the next.

   I think it's much better now that there is a consistent opinion
   presented to education, media, within the scientific community
   and within most politics.

   The consistency brings a sense of certainty and with certain
   comes action.

   So, I'll take back all I've said. I can see the root of my own
   skepticism.

   I was basing my skepticism on having lost my faith in statistics
   as a kid, never really having developed a faith in
   statistics-as-factual. I couldn't; they changed too much and
   news stories from adults kept changing. I _couldn't_ be a
   believer; too much inconsistency. But now things are far more
   consistent in presentation. It's better now. I probably
   shouldn't have been exposed to statistic-skepticism so young. It
   stuck with me even to today.
