I find this topic a bit interesting because it seems to clear to me that global warming is a huge issue. Yes the carbon is absolutely warming the planet, but of course local weather can have anomalies. Now of course there are some benefits to global warming... like up here in Canada we might be able to grow more food year round!

But without a doubt, given the rise in ocean levels, given the severe droughts in places that are used to more rain, this will all be tragic.
But I'm curious if I may ask Jem what your motives are. Often when a debate is presented, be it tobacco for example, most people know what the truth is, yet the fight continues because its in the best interests of certain business to keep the lie going. (ie. that smoking doesn't harm your lungs)
So I'm just curious to ask those people who fight this issue what you hope to gain if you don't mind. Perhaps you own stock in oil companies, perhaps you don't like your tax dollars going to support clean energy, etc. But given the strong push against what I think is an obvious correlation between CO2 levels and a warming planet, why are you fighting for the other camp? Knowing motives usually helps to see the issue more clearly. Thanks!
