The problem is that Global Climate Change is not a scientific theory, it is a political movement connected with the environmental movement. There are many different areas a specialties working on individual theories that tie into the Global Climate Change platform, but I have yet to be made aware of a universal Global Climate Change theory.
It is the political movement which uses environmental and climate issues to drive their agenda that cause many people to have a lot of skepticism regarding even the most basic environmental and climate issues. Then the reaction to this skepticism is that only brain dead morons would be skeptical, and if you don't fully accept these issues as real and in need of significant social and political action, it is because you're hateful and ignorant. Isn't skepticism the default position? Isn't it not only ok but encouraged to approach an issue like this and say, "I don't fully understand this issue, so I'm not going to assume what is correct."
From my perspective, the environmental movement makes individual rights impossible. It is the idea that we must all be controlled because if left to our own inclinations we would destroy the planet. So I reject the people pushing this movement. I think there is a better way to protect ourselves (the planet does not need protecting, nor does the environment, people need to protect their own interests, which is to say the global resources and conditions needed for our survival). I see these issues being used as a political tool to gain a devastating advantage over the opposition. If only everyone were convinced something HAD to be done to stop the threat of Global Climate Change we would see that the measures needed are not compatible with capitalism, consumption and individual rights.
So please understand that I don't think I'm smarter than climate scientists on this issue, but I'm not ready to take them at their word either, and I'm not likely to agree with their solutions. I'd rather the climate change than follow them down the path they've laid out for me.
