OK so explain WHY the rural temps have not increased at all over the last 100 years. Urban ambient temps have risen which is to be expected when you put that many heat sorces in a confined area. I also understand taking 4-5 stations in an urban area and averaging their temps to get an "overall" average for that urban area. Any manipulation of the data should have STOPPED right there, but instead they decided to "adjust" those averages upwards on temp data that was ALREADY artificialy elevated.
Now you also just touched on the whole "glaciers are melting OH NOEEEESSSSSS" that proves man made gloabl warming. OK just for giggles, explain what happened to the 1/2+ mile tall glacier that used to sit on top of what is now New York state a couple million years ago. There weren't any humans driving around in SUV's or flying all over the place in commercial aircraft back then, yet a glacier that used to cover a large part of North America disappeared. There is AMPLE geological evidence to prove it was there.
Based on that, and tons of other evidence, it's safe to assume that the earth has repeatedly gone through heating and cooling trends. Less than 1000 years ago the earth was in a warming period, then rapidly moved into a cooling period, hence the medieval warming period, then the little ice age.
I'm an electronic technician/engineer by training so I have a good understanding of data collection, trends, and methods to analyze data. I've looked at tons of data regarding this topic from lots of differant sources, and so far I've found nothing to convince me that humans are causing the climate to change in any radical way.
My biggest problem with the whole "man made global warming" crap is that it's nothing but a scam for a select few to get rich, gain power and control over a large portion of the population. Carbon Credits?? Really?? Now don't get me wrong and think I'm someone who doesn't care about the enviroment because I do. I'm an outdoorsman. I love to hunt, fish, go camping and like being outside. I think there are plenty of things we as a species can do to "improve" the planet. Recycling is high on that list, and over the last 20 years it's caught on and as an industry it continues to grow and does good work at reducing polution and renewing our resources. I'm also all for finding renewable energy sources, and when the market starts to demand it, as it's starting to, more and more smart people are going to work the problem and develop solutions, BUT the government CANNOT mandate inovation for the sake of political gain. That never works and only causes problems, yet that's what is happening with this meeting in Denmark, Cap & Trade, and this latest bombshell from the EPA. I have a problem with politicians and scientists manipulating a natural cycle of earths climate continuing on it's way of change like it's always done, and then telling me I need to be taxed, controled, and forced to comply so "we can stop climate change".
We can't stop it, we can't control it, we can't cap global temps (yes that was a proposal from one of the countries over there, cap global temps to 2 degrees and not let it go any higher). How do you do that? Tell Mother Nature, "Bad girl, you can't get any hotter."?
All we can do is keep the place clean. If your worried about CO2, plant some trees, you know Mother Natures natural CO2 scrubbers/fliters?
All in all though, I believe the hysteria concerning global warming is way over the top, and anyone who buys into it, and thinks we can somehow control the eviroment, is out of their mind. We don't control the enviroment, it controls us. Always has, always will. If it's going to get hotter, it's going to no matter we try and do. Same if it gets colder. We'll either adapt, or we wont, but throwing money at a problem tha isn't really a problem is just dumb.
