Global Warming Melting Ice Fast

Scientists are now saying that the ice caps are melting at a much faster rate than had previously been predicted. I doubt that learning of a few melting ice bergs will make very much change at all in the world of big business and government. Global warming won't start making us change our ways until some really BIG freaky natural disasters start happening. Like small countries disappearing or really disruptive weather (no sun for a year or no rain for a couple years).
Melting ice sheets could hasten sea rise: study
Studies published in the journal Science, showed that between the last two ice ages - about 130,000 years ago - sea levels increased by as much as four to six meters above current levels as polar ice sheets melted.
Temperatures then were one-degree Celsius higher than now.
But researchers say that by the end of this century, the world could be three to four degrees warmer.
Dr Jonathan Overpeck from the University of Arizona was one of the scientists who carried out the research.
"We're going to cross a threshold sometime later in this century, beyond which major retreat of ice sheets and corresponding large increases in sea level are inevitable and irreversible," Dr Overpeck said.
"We know when the sea level was that high in the past, and we know how much warming is necessary to get that amount of sea level rise from both Greenland and Antarctica." ABC News
