Tree rings go up to 200,000 years?
Carbon dating is as valid as the gore bull warming/climate change models.
sediments are dated ... how?

Sorry, that happens not to be the case.
If you have any legitimate questions on radiocarbon dating I would be happy to address them (but don't even bother with the tripe from the creationist websites -- they lie when it comes to science.)
In the meantime here are some good links on radiocarbon dating:

This site, BiblicalChronologist.org has a series of good articles on radiocarbon dating.

No but they are up to 10,000 years and carbon dating is a valid, scientifically proven and reproducible.
