Rings Around Earth From Ancient Meteorites

HorsePunchKid writes "According to an article on CNN (SNL version), ancient meteorites may have glanced off of the surface and shattered, causing rings around the Earth. These rings, which may have persisted for hundreds of thousands of years, could have had a profound effect on the climate in tropical regions, where the rings would block out light from the Sun. Still rather speculative, but the theory may help explain some patterns observed in the geological record. The idea has been around for a while, and some scientists are skeptical."

Maybe I'm responding to a troll here, but would you like to provide some evidence to back your claim?

Would you also like to explain the marks left behind by the glaciers and the things such as mammoths we have found frozen in them? Everything points to there having been ice ages in the past, even during times when the human race was around.

Also, unless I am terribly mistaken, we had a much more tropical Earth during the reign of the dinosaurs and very very small ice caps. All geologic and evolutionary evidence points to the fact that the Earth has had its warm times and its cold times.

Humans may be effecting the climate now, but we may only be nudging along a warming trend for all we know. We just don't have enough data to know for sure yet.
