re: #164 Obdicut

But science means we’re continually learning new things, so your view would mean that it was precisely those areas that we studied the most that we would be able to say the least about. That makes no sense.

No, it’s not. It doesn’t stop at D— that’s an infinite set of other possible causes.

Have you read any of the sites that Charles links regularly on this subject, like [Link: www.skepticalscience.com…] or [Link: www.realclimate.org…]

You’re making my point for me, thank you. Unless all the variables are known you cannot have a 90% degree of certainty. 90% of unknown is still unknown.
