Au Contraire: "If larger ice sheets begin to recede, sea level could rise rapidly and dramatically. The most vulnerable ice sheet is the marine-based West Antarctic Ice Sheet which contains enough water locked up as ice to raise global sea-level ~ 5 - 6 meters." This is quoted from the USGS page Chris Tracey posted. Now, I don't agree with Shiri that this could happen in a matter of years, but if we don't try to curb what we put in the atmosphere, it could easily happen in another 50-100 years, IMO. I do believe the earth is currently in a natural warming trend; however, I also believe we have sped this process up. > I'll give Chris's words some credence but you're just scaremongering, try not > to believe everything you read. I'd like to hear where you read there wasn't enough ice in the caps to raise the sea level much. I saw a report (on the Discovery channel, I believe) that at one point, millions of years ago, the sea level was a couple *hundred* feet higher, due to the fact that there were no ice caps. Jeff

(...) Jeff is correct. See my last post(5623). For general information- scientists measure the amount of ice on the planet at a given time by looking at oxygen isotope ratio in deepsea sediment cores. ^16-O is selectively stored in ice over the (...)
