Hi Jonathan,It can be confusing the nmbuer of claims being made that the world is warming / isn’t warming and that’s because the issue has become somewhat divided, often for partisan reasons.No doubt what you’ve been taught in school is correct. If a school were to knowingly misteach it’s pupils then it faces prosecution. Global warming has actually been on trial several times in courts of law and on every occasion the Judge has ruled that the facts and science behind global warming are accurate.Those who don’t accept global warming is happening don’t have an argument against the theory. Instead they have used more than 100 different excuses ranging from claims that the world is cooling, that Margaret Thatcher invented global warming, that it’s because Earth is moving closer to the Sun – all manner of unrelated claims.In your question you mention that you’ve learned that a lot of people are against the idea of global warming. In reality there’s not that many. It’s broadly accepted the world over, the only notable exception being the US where it is more of a political issue than a scientific one.If you look at global warming scientifically then there’s no question that it’s happening. No doubt you were taught that greenhouse gases retain heat in the atmosphere and that the more of them there are the more heat is retained. What you may not have been taught is the mechanism by which these gases retain heat, this is something that is governed by the laws of quantum mechanics.You may think that it would be pointless to try and argue against the theory of gravity, and you’d be right to do so. But it’s even more pointless to argue against the laws of quantum mechanics. Not only are these laws universal and invariable, but they’re the most powerful and successful of all scientific laws. Trying to argue against them really is futile – not that it doesn’t stop some people claiming there’s no such thing as global warming.Because the science is so solid, it’s no surprise then that there isn’t a single scientific organisation on the planet that disputes the theory of manmade global warming.So instead, what we’re left with are a nmbuer of uncoordinated, unscientific, and largely uninformed individuals who, often for personal reasons, object to the notion that the world is warming and we, as humans, are having a hand in it.It’s very telling that those who argue against the theory NEVER address the issue as a whole, instead they focus on the minutiae and on the distortion of reality. By adopting this technique it’s possible to ‘disprove’ anything. Take gravity for example, if it existed then trees would grow downwards not upwards, water could never evaporate, birds and planes would crash to the ground, the atmosphere would be sucked down to Earth not up in the sky, Earth would compress itself into a tiny ball etc etc.This is an example of the style of argument used by those who reject the theory of global warming. They latch on to an illogical argument and run with it, steadfastly refusing to acknowledge their own ignorance and basically doing everything they can to avoid exposure to anything that opposes their fallacy.
