These things are unrelated, except that we may make some interesting evolution happen once we kill ourselves off.
CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.
Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.
(see links below)
How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.
There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.
Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.
Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

if evolution involves the creation of man who turns around and pumps enough CO2 into the atmosphere to accelerate greenhouse effects, then I guess you could call it evolution. I would bet that most scientists would argue that it's man made and not evolution.
to some extent, the greenhouse affect is evolutionary. It's why the earth's surface is the temperature it is and why life can be sustained. Screwing with it is not evolutionary.

Greenhouse affect due to evolution

They're totally different... "greenhouse affect" is involved with global warming.
