A discussion with a right wing climate denier

[kristopher]

6. You will never persuade your friend about something as complex as AGW.

But there is a smaller piece of the carbon cycle's disturbance which I've had some luck with - ocean acidification.
It is an easier picture for someone to wrap their head around since nearly everyone is familiar with the way life is destroyed to keep a swimming pool clear.
It is also backed by measurements that are pretty straight-forward.

Start here and then cast a google net to find some sources that you think best match your friend's type of trusted sources.

If he/she finds ocean acidification plausible, it is a good first step towards tearing down the wall of certitude protecting the entire climate denial structure of belief.
