If you mean whether global warming is down to human activity, I'm also undecided - I've never got round to examining even the most basic evidence closely enough. Even then, there's bound to be a limit to what a layperson such as myself can grasp.

It's curious that, lately, there seem to be those who now doubt even the premise of the question - that the ice caps are melting and the sea-levels are rising at all (or that it's that unusual if they are). I always assumed we could at least safely agree on that much, and the only question was over mankind's contribution to it all?

I often read that the vast majority of the world's climate scientists are largely in agreement, not only on the question of overall warming, but also the likely correlation between it and rising CO2 levels in the atmosphere. Scientists can be wrong of course, they're not fool-proof, but when I consider that apparent level of scientific expertise and consensus alongside the political and corporate vested interests of the anti-camp (which is unquestionably more ignorant of the scientific data, but some of whose members have very deep pockets) – I'm inclined to side rather more with the former than the latter.

There are of course vested interests and a few deep pockets in the climate change "movement" too, and I don't doubt that the environmental movement has its fair share of tree-huggers marching without much of a clue as to the evidence. But surely not to the same degree.

So in summary - if I had to step off the fence right now, it would NOT be to the side currently screeching "it's all a sham". For now, I will sit tight and hope that those more in-the-know will prevail. (I suppose we shouldn't count on it though)
