A simple search on the internet would of brought you to wiki:

The ice core drilling and ocean floor core samples make it abundantly clear that over the last million years there have been 10 cycles.
That has more foundation than all the computer models in the world. It is based on the facts not supposition, hockey sticks or wags.
Don't waste your vote, vote Green or Independent in the next election.
Go ahead. Keep denying it. But you're children won't be able to, and they'll blame you for their problems, as they'll be right to do so.
Has it?
This is why so many of us think you deniers are idiots.
If we can agree that the earth changes orbit and tilt and that in turn causes heating and cooling cycles of the earth as well as solar radiation then we have a place to start from.
Heating of the earth's core as a result of these changes increases the amount of precipitation which increases the amount of snow and reflected light which in turn creates cooling temperatures and brings on an ice age.
Greenhouse gases also increase the water vapor, increasing the snow, triggering an ice age. Like I said before, its cyclical, maybe we sped up the cycle a few decades. In the galactic scale its a non-event.
Either way we better start building bio-spheres with fusion energy reactors.
