A better term for "global warming" is "global climate change". Rising temperatures in one area will alter jet streams and such and lead to cooler areas in others. That's why some whacko conservatives use thermal data in some particular locations to try to downgrade the threat. Sure the warming is a natural process. But as far as we know, it's never been this rapid and all of our activities most certainly have a huge effect by accelerating this process.
There's still doubt because oil giants and their partners (which includes many people within the White House) would lose a lot of money if people start to drift towards alternative energy sources as opposed to oil. Factories and other industries will have to refit everything so that they're environmentally friendly. They don't want to comply since refitting their operations will cost them money. Less money --> more complaining.
People are simply too lazy to change. Any lack of convenience is enough of an incentive NOT to go green.
"In 100 years, the temperature has risen 2 degrees. Yes 2 degrees."
2 degrees Celsius is HUGE. It may not seem like much, but when you think of the average temperature around the whole world rising like that, that is A LOT of additional energy within just 100 years.
"The scientists have found that by scaring everybody, they get more research grants."
Ok... so there's only one right answer? It's either lie and say there's nothing wrong happening... or tell the truth and be accused of making up stuff for more money? I thought is was a scientist's job to tell us something we don't know and if there's something that needs to be changed. Then there's people who say there's not enough evidence for climate change... shouldn't we then fund research to solidify the arguments? Such contradictory arguments!
"I'm also wary of any religious-like devotion to a cause that is unproven and (coincidentally) followed by those who happened to be left-wing anti-capitalists and socialists."
Climate change is scientific consensus. Any dissent is by "scientists" paid off by the Bush Administration and oil giants to oppose everyone else
By the way... not all left-wingers are anti-capitalists and socialists... That would be like all right-wingers are rednecks that think torture is ok when that's supposedly why we needed to stop Saddam Hussein... Congratulations, you just made yourself look like an idiot.
Climate change is real and we have to take just a slightly more conscious approach to it. We don't really need that much more effort. Any short-term costs will definitely make up for itself in the long-term.
