How do man made global warming theorists account for the 1800 mile retreat of the glaciers before?

They can't nor do they want to. To give credence to this would shoot their "theories" right in the foot. Check out a website called junkscience.com if you want more and real information.

Well, global warming is happening, and the fact that glaciers retreated before from natural causes doesn't mean we aren't causing it now. That's like saying, "A rabbit died of natural causes yesterday, so the rabbit I killed today isn't my fault". Global warming has been shown by overall trends, not by isolated incidents in Malibu where it happened to snow. I believe global warming is a real threat to humanity because of the clues given by heat waves, sea-level rise, melting glaciers and warming of the poles. This has been shown by unbiased scientists. All of the denial in the world won't make the problem go away.

They are called Milankovitch cycles. They occur about once every 100,000 years. The Earth does indeed warm and cool on its own, but the current rate of heating can only be explained by man made green house gases. That is the scientific consensus.

Go to the SCIENTIFIC ORGANIZATIONS, not political websites, for your global warming information.

It's not about the environment. It's about greed and envy and the father of all lies making people hate progress, happiness and a strong economy. It's a minor lie. The road to hell is paved with good intentions and he's pouring asphalt at an alarming rate. Of course the lie in the global warming silliness is that mankind has no power to warm or cool the earth. It's the height of arrogance to believe that's even remotely possible.

Just one Mega Volcano could reverse this for years, Pulses of the sun can ebb, the bigest cause of global warming is 10,000 scientists and 500 politicians and 500 actors all talking too much. We as a earthly population will be doomed one day, no mater what we do. Live life the best you can and leave as little a footprint as possible.

Global warming? LMFAO! It friggin SNOWED in Malibu this past winter! Half the trees in Southern CA are dead because of the 20 degree overnight temperatures we had last March! Funny how the more liberals insist on man-made global warming, the fewer hurricanes we get hit with and the colder things get!

Two different situations. Global warming can occur naturally--but it can also be manmade.

The junk science nuts don't get this. But its like saying because some forest fires are calused by lightning, careless campers don't cause any forest fires.

And that's just how stupid these 'deniers" sound.LOL

The evil infestation of people on the earth. People breathing. If only all people would die everything would be ok.

Dude. Those pesky dinosaurs and their damn SUV's.
