"There's all this talk about consensus, but there's really no room for debate."

  • The Earth has done fine before us and will do fine after we are gone. Typical human egocentrism to think we have any bearing on what happens on Earth.

  • @MrNDSteinbach By destroying the economies of the world and losing national sovereignty? No, thanks.

  • @NefariousBanana I agree with you 100% on everything you said. We need to pay attention to Global Warming, but all human beings, not the gov. Vote for Ron Paul! VOTE LP!

  • ClimateGate? what scandal, the right wing raking things out of context. and we can have debate, as soon as the anti-global climate clan has better evidence for their position

  • @fermista Spot-on. I'm a libertarian, and I think Global Warming is real. Do I support government regulations like cap-and-trade? Hell no.

  • Does anyone else find it funny how the US is pretty much one of the only countries that doesn't want to do anything about global warming because it "doesn't exist"?

  • How stupid is this person? I hate being disrespectful but the science DOES say that global warming is real and manmade. And the last part? How about the wildfires in Russia? Hurricane Katrina? Droughts and flooding all over the world where they shouldn't be? The coral reefs dying because of absorbing too much CO2? I am disappointed that the Libertarian Party would post this (seeing as it has no scientific or factual backing).

    Just look upSkeptical Science and Union of Concerned Scientists

  • @SugarMonkey528 So basically you're saying that correlation doesn't imply causation, I totally agree there. However I'm not familiar with the details surrounding the hockey stick. If there is a fundamental problem with the hockey stick graph, I'm sure the scientific community would've addressed it by now. Al Gore isn't a scientist by the way, he's just a contributor to the politicisation of a climate science issue. FYI, I'm a physicist and I loathe the politicisation of science, from both sides.

  • @fermista Do you drink sweet tea? Here in the South, that's about all we drink. If you do, or if you've ever made lemonade, you'll know that hot liquids hold more sugar than cold liquids. Just try dissolving a cup of sugar in a gallon of ice cold tea ... doesn't work well.

    Our atmosphere is much the same. The warmer the air, the more carbon dioxide it holds. Look at the famous hockey stick chart from Al Gore's An Inconvenient Truth. The temperature actually rises BEFORE the CO2 levels go up.

  • @SugarMonkey528 Of course there is natural climate change, but carbon dioxide is a known greenhouse gas, so pumping heaps of it into the atmosphere will obviously have some global warming effect at least. Think of it as unintentional terraforming. You're right that climate change doesn't necessarily mean for the worse. Some things could get better, others worse. A warmer global climate would mean higher sea levels and more hurricanes. On the other hand, new areas of land would be inhabitable.

  • @fermista I will agree that there is some evidence for global warming, but the "evidence" for AGW is suspect at best. From a purely scientific perspective, the earth must either be warming or cooling at any given time. Science has evidence of multiple ice ages. Had the last ice age not ended, due to global warming, humanity would not exist. So the question is, is global warming such a bad thing?

  • @SugarMonkey528 The scientific evidence for global warming and AGW is strong. Scientific theories don't pop up out of the vacuum, they have to have strong and verifiable evidence to back them up, otherwise they are dismissed by the scientific community as not a good representation of nature. I agree that governments shouldn't be pushing for further regulation and taxation of markets, using AGW as the excuse. But regardless of whether they are, this doesn't mean the scientific theory is wrong.
