Issue With Comments Mgmt - Magazine Theme

[SkiBum]

I was reviewing Webmaster tools for my blog and I noticed that I had a warning for 25 pages on the site with duplicate meta descriptions and title tags.

Digging a little deeper, I see that the duplicate descriptions and tags relate to 5 posts that have pages and pages of comments and when I look at the pages that Google is reporting as duplicate content, they are ......

http://site.com/post 1/comment page 2
http://site.com/post 1/comment page 3
http://site.com/post 1/comment page 4 etc....

This is the case with several aged, popular posts, and it seems to be affecting the site's performance.

Not sure how to handle it, but there seems to be a correlation between when these warnings were posted in Webmaster tools and a pretty good hit to traffic & rankings....

Can anyone help with some advice on how to handle this?

Thanks
