I always understood that it was essentially a sine wave, within a larger sine wave and so on.
That means that whilst we're still on our way out of the last ice age (so it's going to get warmer) we may be on a shorter term downward curve.
And, at the moment we're seeing more extremes of weather, hotter/colder/wetter/dryer etc.
Whilst I think that our carbon footprint(tm) may have a bearing, I do think that the wider world of natural gaseous outpourings from livestock and volcanoes etc is far more significant than the continued manufacturing of say Aston Martins.
There's been interesting comments around the fact that hotter = more cloud, which in turn will help cool things.
Personally, I think we don't know what's happening, hotter/colder etc, but that shouldn't excuse abusing the world we live (points at China) in the same as it shouldn't mean we have to revert to feral living.
