Did anyone link Junk Science yet? They explain why the computer models are innacurate. Also, it was reported that there's more ice in the arctic now than there was in the 60s. Also, where I live, temperatures appear to be declining more and more. A single volcano can (and does) put more carbon dioxide into the atmosphere than a person ever could hope to do. If people are concerned, they should probably just plant trees, since trees eat carbon dioxide.
The worlds temperature has risen half a degree in 50 years - fact.
Temperatures are beginning to decrease, it would seem. Compare 2008 to 1998 (we had 114 or so in 1998, but few days even made it to the upper 90s last summer), and you'll find that temperatures do appear to be dropping.
Anyways, the computer models are flawed (check out the wonderful report on Junkscience.com) and it's all about money. See, science works on grants nowadays. You produce results, and you get money to continue your research. Certain ideas can become entrenched, even if they are false, because scientists, like sane people, will try to get as much money as they can, any way they can. It stopped being about real science and taking responsibility for this rock we call a home ages ago.
Frankly, we won't see any big breakthroughs in science until this changes. There won't be another theory of relativity, or light-speed space-ships or anything of the sort. Our computers will progress, getting faster and cooler, but everything else is going to slow down and stop, because while scientists are supposed to be detached, unbiased observers, the fact is that they aren't. They're people. If someone makes a claim, and this claim goes against everything that a scientist has invested his career in (my father, for instance, has numerous metal fatigue/joining claims and patents to his name), that scientist will fight the idea. For instance, my father, brilliant man that he is, fights against composites and says that composite airliners will never work. If composites manage to eliminate metals in the aviation and automotive industries, he'll be out of a job, so he's almost obligated to fight it.
That concern for money is what's going to hold science back.
Also, if global warming was an issue, mandatory pollution-reduction laws would have been imposed on countries that don't have their own by now, and this just isn't the case.
...also, I clicked the wrong votey thing because it's 5 AM and I just got off an 8 hour shift. ._. My bad.
