News pagination caused duplicated meta descriptions

[Erhaoen]

Recently I received warnings from Webmaster Tools about duplicated meta-descriptions. Pages generated by news module pagination has been indexed by google as standalone pages and their descriptions remain unchanged.
Is there any smarty tag I could use to gain unique meta-descriptions in this case? Or mayby it's possible to change the way how pagination works, so it cycles but doesn't generate new url? Any advice highly appreciated.
