Climate change is a natural phenomenon and can't be stopped. End of story.

Actually, until human industry took off it was abnormally stable and we prospered as a species, now we've re-released the carbon, it has started up again.
We've undoubtably affected out planet.
Well no, the temperature of the planet does vary. For instance there was a "mini-ice age" in around the 1600's, and a "medevil warm period" in the early middle ages. So, it is quite difficult to establish if we are in another natural warming period, or indeed this warming period is artificially induced. Rather like nature and nurture.
Here's some graphs-

This graph would support the notion that there is artificial global warming. However what's interesting is that the temperature changes are gradual, unlike what we see towards the 20th century where the temperatures increase sharply.

However on this graph the recent rise in temperature seems only a minor blip, and is dwarfed by the rising temperatures that which occurred 11,000 years ago. The significance of anything is all a matter of scale.
My position is, better safe than sorry. It is possible that the temperature of the planet is naturally increasing, and human activity is increasing the rate of temperature rise unnaturally. I'm all in favour of developing new technologies to reduce CO2 emission's, just in case we are actually contributing to rising temperatures. However, the best (and most realistic) approach to combat climate change is not to revert back to the middle ages as some radical climate change fundementalist's seem to imply, but develop new technologies and improve on existing technologies making them more efficient at reducing CO2 emmisions.
