My head can't cope with this, it's far to much for a pre midday conversation! However - I think I'm getting all muddled between Mike's comment that global warming is the ice melting and others comments on rising sea levels. I'm no expert bu, a quick glance at this website suggests that most of the polar ice caps (in antarctica at least) have always been coupled with land, so I'm not sure Piers' comment would be right. Secondly - the melting of the ice isn't global warming, but a result of it. This will raise sea levels, wont it (more water in the sea), but isn't the worse effect the affect this will have on the planets weather? You know, destroying the gulf stream etc? If I'm talking twaddle, feel free to ignore, but if you know and feel like, please explain!
