Anybody who believed global warming was man made are having questions now?

Now everybody (all scientists) accept that we had a very warm period in the middles ages.. vineyards in england.. etc etc. and that was followed by a very cold period round about 1600(little ice age).

So if those extreme climate conditions werent caused by man then why does this one have to be caused by man?

There are various explanations, I think having read all of them that "man made" is the least compelling.

We can neither stop it nor cause it imo..... only learn to live with it.

Are you saying CO2 in the air doesn't affect the climate, or that there is no CO2 in the air?

The CO2 in the air effects the climate... however the effect it has on the climate is very tiny I think appears to be the most llikely case.

With Global Warming being a mostly natural effect.

The problem is even a very small increase can lead to large changes. A small increase in temperature could help to reduce ice coverage across the planet. Ice is the most efficient reflective surface on the Earth and so a decrease in its distribution will allow more sunlight to be absorbed and hence create more warming. Further warming would raise the temperature of the oceans which would release more CO2 into the atmosphere creating an even larger temperature increase. This is the problem with the whole issue. No one can predict how all these independant variables will react to even a small (but perminant) temperature increase. 

Global warming (and cooling) are natual effects but the issue here is that we are adding a brand new variable to the natural system which has balanced itself out over great periods of time.
