RE: Way out of proportion
Is the earth going through a warming cycle that accounts for some of the increases in temperature?
Well, the conservative nay-sayers keep repeating the mantra that the "hockey stick" chart has been completely discredited, but the climate scientists don't think so. And the "hockey stick" chart looks like this.
Now, I'll grant - I suppose it's possible that there's some natural warming cycle that could be represented in that data, but the fact that the graph pretty much launches upward at the same time the Industrial Revolution took off is an incredibly suspicious coincidence. That evidence alone makes a pretty strong prima facie case for the man-made global warming hypothesis, and it's something that needs to be directly addressed.
It's not enough to say "maybe it's not us" - the anti-warming folks need some pretty strong evidence showing that it's just coincidental, which pretty much means they need to prove its real cause.
I'm certain there is much more than can be done, but those are the ones I stick to my guns about--especially the use of trains and Mass Transit.
Personally, I think the solution is more likely to be more high tech. I expect we'll find a relatively quick way to slow down the process - taking some natural carbon sequestering system and delaying the mechanism that causes it to re-release its sequestered carbon. And I think we'll find a more direct solution to the problem after that - a relatively small change in the Earth's albedo shouldn't be completely beyond us, and that's all it would take.

RE: Way out of proportion
There are at least two schools of thought that the more 'radical' (for want of a better word) global warming proponents fail to address. Those are:
I'm no climatologist, but truthfully, I personally believe we may well be experiencing a combination of the two. However...does that mean we quit trying to fix it? Nope--I just question the wisdom of the methodologies address. For example, Ethanol production is far more distructive than the proponents of this alternative fuels want us to believe.
I'd rather see more strict requirments on the auto manufacturers. Doubling the fuel economy will reduce our oil dependency by 1/3, and reduce carbon emissions by just as much. We should also fast track development of alternative non-polluting fuel sources, decrease the average commute time---or conversely provide adequate mass-transit, and go back to using trains for long-haul freight. I'm certain there is much more than can be done, but those are the ones I stick to my guns about--especially the use of trains and Mass Transit.
