    Is it real or a scam? Give evidence to support your claims. Also yes, the earth day thread asks if you feel strongly about it, however this thread is asking if it is a real or a scam.
     
    No, because there's still snow here in the lake district in England.
     
    I think there are signs Earth's climate is changing, however I do not think man-made global warming is what we're seeing. If it was in fact humanity's fault, we should put restriction on factories before even thinking about cars.
     
    I believe that global warming is very real, albeit not as bad as some people believe. The fact of the matter is that we have seen a decrease in the amount of ozone in the atmosphere (ozone is primarily found in the [EDIT:] stratosphere and is important in absorbing UV-B and some UV-C light). Naturally, ozone breaks apart into diatomic oxygen and an oxygen radical, and they eventually come back together. Many of the chemicals we stick into the atmosphere can effectively kill ozone, such as chlorofluoric carbons (the stuff that used to be found in hairspray and other aerosols). Sulfur dioxide and carbon dioxide are equally as bad (sulfur dioxide can form aqueous sulfuric acid, and cause acid rain, and carbon dioxide is perhaps the best known greenhouse gas).

    So, scientifically, there are many reasons why humans DO have an effect on the environment, especially with global warming, but I don't believe it's nearly as bad as, say, Al Gore says it is.

    Regardless, it is real... so even if it's not as bad as some think, shouldn't we try to correct it either way?
     
    If anything, the climate is shifting to be cooler where I live. The past three years here in Houston, TX, we've had relatively harsh winters, with snow appearing twice per season on average...as opposed to the 200 years before that when our winters were really mild and it snowed once every ten years on average.

    So, I believe "Global Warming" to be a misnomer. The phenomenon, regardless of whether it's caused by man or if it's the earth's natural cycle, should be called "Global Climate Shift".
     
    It's a constant curve that has been going on since the earth stabilized. It gets hotter on average, it gets colder on average, it gets hotter on average, colder on average, so on and so on.

    We just so happen to be in a warmer period after a colder period (the most recent ice age). It'll eventually start sloping back down (though remember, we're speaking in thousands of years for these changes to take place).

    But the climate shift is caused by the warming of the Earth, which melts the polar ice, which messes up the underwater currents that make places warm.

    I just hope the emperor penguins aren't affected in any way. That would be so bad.
     
    In one hand, average temperatures on Earth have been rising in the last years.
    In the other hand, winters are also harsher than before.

    There is evidence that points to Global Warming being real and on the rise, so I believe it does exist. It's a natural thing, yes, but at the current rate it is not natural.

    That doesn't mean anything. Even though Global Warming does exist, snow still exists. And England is not what we could call a warm place, is it? Temperatures may rise, but some places on Earth may continue cold. It all depends on the places.
    In Southern Europe, for example, temperatures have been on the rise in the last years. Four or five years ago, the whole Greek forests were on fire. Unless a large group of specialized people decided to put those whole forests in a wildfire for no reason, it was certainly not a fire caused directly by human hands.

    But there's always the counter-argument of winters getting harsher. As most of you know, there are underwater currents in the ocean. The melting of polar ice messes the currents up and, in result of that, some places are shifting between incredily hot and incredibly cold.
    And also, even with winters being harsher, ocean temperatures have been rising. That's really bad for some of the living beings in there. The rising ocean temperatures are a strong proof of the Global Warming, it's impossible to scam that data.
     
    Yes it is real, there is no doubt about that. It is however, not caused by human to the degree we are hyped to believe.

    The so called fact that humans contribute most to global warming is due to the fact that thousands of people are employed as environmental journalists. These people have to make stories and so they slightly exaggerate certain aspects of human intervention in order to get a nice juicy story.

    There are a number of reasons for more natural influence in global warming and I can't explain them all right now as I'm trying to make lasangne. I will however state that one of the main reasons is Milyankovitch Theory.

    I know it's lazy making wikipedia do the work for me but if this lasangne burns my housemates are gonna be pissed. I'll make more of an input later.

    I think that pollution is harmful and whatnot, but I think "Climate Change" is a scam, mostly because the scientists can't decide what adverse effects will come around. 30 years ago it was Global Cooling, 5 years ago it was Global Warming, now it's Climate Change. I'm not saying we should keep messing up the planet or anything, but I'm betting that we're just going through a rather warm spell that was helped through our carelessness, but that we'll recover soon. So, I think that we need to slow down, realize we're in no emergency, continue to put great amounts of effort into alternative energy, recycling and other good practices, but get away from this "end of the world in 50 years" idea.

    I got a D in Physical Science, so instead of trying to understand the data (which would take a great deal of effort), I try to understand the way the scientific community acts about it (my science professor happened to think that Climate Change wasn't a severe issue either). So far, they just seem like a confused lot that keep contradicting themselves and can't agree on anything (no, I'm not referring to the above paragraph, mostly other public issues they take part in). I'm still doing my part to keep the planet alive and healthy, but I think we're way overreacting in some areas (America, I feel like we're taking it pretty good: pushing the message and doing our part, but not putting absurd and unnecessary restrictions on the people's freedom).
     
    Harsher winters are a sign of global warming/climate change/whatever name makes you happy. Small changes in overall global temperature have effects on local weather patterns which can have all kinds of drastic effects such as more frequent tropical storms and harsher winters.

    That sounds quite interesting: usually, we automatically assume it's our fault. I've never heard of this, and this is worth looking into (even if I fail to understand the most basic of points XD )

    Quoted for truth.

    I once was all worried about all this Global Warming jahjah till I saw Burt Rutan talk in length about climate change at EAA AirVenture 09, changed my opinion completely.

    They aren't all "environmental journalists" though. Those people are just cashing in on theories made by actual researchers.

    Also, a lot of the sceptics are utter crackpots. For instance - in the news today, there's a man who thinks that global warming is a myth which socialist forces are using to cover up their plans to create a new world order. And lots of them are like that.

    So too are some environmentalists, burning SUVs and such (which ironically produces CO2).

    I'm not saying that we havn't heated up the world to a degree, but the main cause is nature.

    What shadow said. I would repost saying how I agree with it, but quoting it is easier.
     
    I agree with that too, the sun is just in a warm phase.

    At very best we are speeding up a process nature started, cows produce far more greenhouse gas annually than cars do.
