Hmm again - I thought relative density was about displacement anyway - the volume of water an object displaced in relationship to its weight or the other way around, or something - mind you it was a long time ago and I never followed the science path when the time came to take the split (1962 I think!)

So what's the difference between millions of tons of sediment and minerals eroded into the sea on the one hand, and ice on land that ends up in the same place on the other - with 2/3rds of the planet being water and god knows how deep overall will the addition of the ice caps volume really impact as much as is thought?

Global warming, and the increase in evaporation leading to a more turbulent water cycle and consequent weather system changes is something I can relate to, but I just wonder why we haven't seen water levels rise dramatically already through natural erosion processes - if you put more land into the sea then by rights the sea has only one place to go, upwards, but that isn't so evident.

And if the ice caps do make a difference, then how much would it take to remove x million tons of tidal covered coastline to higher ground to accommodate the equivalent of the ice caps mass - maybe a few billion buckets (one per person of the world's population) would do it.

Probably screwed up logic, but it's Friday and been a long week
