Approximately 25 years condensed into a few sentences...
This very site is responsible to some extent for my not being a denier any more. Give yourself a big pat on the back.
Al Gore's and others' "the science is settled"-style statements all those years ago led me to shout "Eh? Science is never settled." As I have no disbelief in evolution, the Big Bang theory of cosmological 'evolution', relativity, quantum stuff etc, I was unable to explain to myself why i had this problem with global warming. I'd read a few anti-AGW books by authors who i now realise are thought to be, at best, controversialists: Christophers Booker and Plimer for example. I'd also read Bjørn Lomborg's
The Skeptical Environmentalist. Edit: I did think some of the reactions to those who did doubt were somewhat extreme. Eg,
the reactions to Lomborg's book.
I rationalised all this to myself by accepting any science on, say, sea level changes in Bognor Regis, temperature changes in local areas, etc. At the same time, the IPCC were, in their assessment reports for policymakers not 'doing science' but being political.
I came across International Skeptics about four or five years ago, when
The One With the Whales was the current JFK thread. (Someone on
https://www.apollohoax.net/ had referenced his site.) Having read a lot - far too many - of the threads in the conspiracy section, I realised that I was doing the very same thing with climate change as woo-followers do with their particular alternative histories. I was taking heed of any anomaly and ignoring the vast bulk of evidence.
Sacrilegious, but Richard Feynman is a smidgeon to blame. His quote: "
It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong." can easily be misunderstood to mean if anyone finds any error, chuck it all out.
I would say that off-hand dismissal doesn't work when trying to persuade. It's ineffective with Truthers and the like and probably will fail with non-mainstream people of all sorts.
I appreciate that there's a stand-alone thread for this sort of stuff, but I hope the mods will leave this post here.
Edit: The amusing final straw was the meme that climate change was invented so that 'they'- yup, them again - could tax us. In my limited experience, governments of all hues don't need much of an excuse to raise taxes. A massive CT seems unnecessary.
