Hmm...I'd like to add my two cents worth on global warming:
1. Is the climate changing? -Yes
2. Did man cause it? -Not likely, the highest carbon ratings were before man even had cars; I'm not saying that humans haven't helped it along, mind you.
3. Can we do anything about it? -I haven't heard anything that would work, refer to nuber 4.
4. Did you know this has happened before? -In the middle ages there was a period (that had just followed a freaky cold cylce) that scientists call the Warm Median (or somthing like that) then, for 200-300 years (ending in 1850 or so) there was something called 'The Little Ice Age'. Then the weather got warm again. So, why are we surprised that the earth might be having another cycle? We have data from a cool period, to a very warm period, to a little ice age, to a warmer one; I don't know about you, but that's pushing coincidence a bit far, I'd say it could be a pattern.
5. How much do we know about the earth's inner workings? -Jack crap; we can't even figure out how the human body works and we can watch humans be born, die, and cut 'em up to see what's inside.
6. Have we treated our planet poorly? -Of course we have, but no amount of fear will change that.
7. Do scientists really agree on 'global warming'? -No, and they get really steamed when someone quotes stats that aren't real.
8. What can we do about it? -The same answer for everything, live a cleaner, better life, and take care of your fellow man.
So, all in all, we have a seriously hot political issue. And we have only scientific data from one earth, for only 250 years at best. You could ask any scientist, "Can you tell anything from only one specimen if you don't know its birth/beginning?" They'll say no, and we frankly, no far to little about our quaint little planet than we think. And since we have no celestial bodies to compare it to, it's a game of wait and see.
I refuse to be cowed into thinking the world is ending, but I will continue to research it, live better, and extend my personal sphere of influence to help those around me. It's past time (too late, probably, but when has that ever stopped me?) that humans began to take responsibility for their actions, and just maybe if we stop fighting and screaming we can help our planet. We are supposed to be the most itelligent creatures on this planet, let's act like it, shall we?
