The point about global warming is that all the available evidence shows that:
1. It is happening
2. It is man-made.

Why is that a problem? well, because we dont know what the consequences could be, we dont know how to stop the rising temperature or if theres a limit or if or when we can reverse the trend.

All of the above could happen, or it might not, some of it may not be due to GW and some of it may be. The fact is that we are messing with earths ecosystem, which is the very reason we are here in the first place. We grew up and evolved as a species on this planet, under these conditions, how will a rapid(geologically rapid 100-200 years) change in climate affect us as a species? how will it affect millions of other species? How will it affect weather? viruses? diseases? deserts? forests?

We don't know

Thats the point. some of the above are possible consequences of global warming*.

*or some denialist pulled it out of their ass and put it on the web so that other denialists could impress us all with their extensive lists.

lol... classic sift comments.

Not to 'feed the trolls' too badly, but to the last poster its dubbed 'climate change' for a reason, and have you not heard of global dimming, or metric tons of climate related research you just pretend doesn't exist? Oh wait, a dozen studies can be interpreted to agree with your views, while merely thousands very clearly disagree? yeah,... ok... obviously its a conspiracy and we're all sheeples... its the only logical answer!

And then the energy note... the many ideas you avoid include reducing current demand for energy (incentives to address energy inefficiency in homes and businesses, for instance), encouraging private power generation (incentives to install solar hot-water deal on the roof), and transmitting power from areas like offshore or 'wind belt' areas, high solar areas, etc. efficiently to neighboring areas via huge, buried, crazy-insulated cables. Anyhow, I acknowledge there are misconception about nuclear, but until fusion ushers in a new atomic age there are good reasons why Americans have repeatedly rejected fission power plants dotting the country... and if you don't know them and address them in your argument its odd to even argue for nuclear in the first place. I mean, would you not agree that China and France have histories of doing dumb shit in the past? So, yeah, an odd way to argue your point.

In the late 90's there was still an inkling of debate over how and why climate change was occurring so rapidly.

debate is over. debate is over. debate is over.

The story is more complicated now, as we have a better understanding of the impact of 'global dimming' which has essentially masked the effects of 'greenhouse gases', which models always predicted should have be more potent. The story now is how do we, on a global scale, maintain this balance while removing ourselves from a dependence on burning sequestered carbon, and how much time do we have?

reminds me... theres a great Nova episode (on PBS in the States) this week on pollution causing a dimming of the sun's light on the earth, and how 'global dimming' has been masking the true effectiveness of greenhouse gases.

Your Horizon Global Dimming Sift is dead - but there's a replacement here: http://video.google.com/videoplay?docid=39520879762623193

I wasn't saying anything substantial with the cow fact - just that Choggle's avatar reminded me of this. I even dis-proved its relevance with the point of planes causing 'Global Dimming' - the ironic counter-force to global warming (which will cause even more apocalyptical effects!) YAY!

Hmm, yeah - bit of an anti-climax (not bad enough to deserve my rare down-vote; as I 'don't believe its hype').

Random related fact (ties into your avatar too, Choggle): Cows produce more polution then planes...Although, cow crap not causing global dimming - so may have to re-think that theory!
