So now we are told by the scientiest the long term sea level will fall - see http://news.bbc.co.uk/1/hi/sci/tech/7282142.stm - based on geological processes that are deepening the ocean's basins. Its going to fall about 120 metres over the next 80 years or so according to Dr Dietmar Muller of the University of Sydney, Australia.

What is interesting about his research is his map showing sea-levels at the time of the dinousaurs, which show that a significant proportion of land on today's continents that would be under water.

Presumably the dinousaurs were not terribly jetset, concerned about their carbon foot print, and generally raping the environment like modern man. That could suggest then that these things are cyclical, and subject to timescales that make our contribution to the saving or destruction of the climate seem like a drop in the ocean.
