It is true that the Earth goes through cycles of cool and warm periods over the centuries, but if you look at this BBC report, it clearly presents scientific data the suggests there is a strong correlation between C02 levels and development since the industrial revolution. The increase we are experiencing in C02 is a significantly higher peak than any of
those in the last 800,000 years. And it looks to be going up and up.
The fact that man came along, and has been minding his own business until the Industrial Revolution kicked off a couple of hundred years ago resulting in dramatic changes in agriculture, manufacturing, mining, and transport, which in turn, resulted in a surge in global emissions of C02 – the like of which the planet has never known, is unprecedented.
Climate change is a natural phenomenon. But to deny that dangerous climate change is not occurring as a result of our burning fossil fuels and destruction of rainforests (note that every month we lose an area the size of Belize), for example, is to deny the fundamental scientific principle of cause and effect.
Sure, I agree that the average person will make little difference paying for carbon offsetting, but people like us who do a lot of flying, do have a responsibility to try and keep things in balance. If we all did it, or if there really was an effective environmental tax, then I am sure it would make a difference. At the end of the day, though, it’s the big polluters who have to change their ways – but at least as individuals we can put pressure on them to do so.
