  Melting ice brings new global warming worry
Updated 19 July 2002, 07.34
Alaska
Global warming is getting even worse after scientists discovered ice was melting faster than they thought in Alaska.

The scientists keep an eye on the speed ice melts to work out how bad global warming is, but until now have only found it at the north and south poles.

Now they've worked out that the ice glaciers in Alaska are also melting fast, which could see sea levels rise much quicker than people thought they were going to.

Sea levels are tipped to rise in the future, perhaps causing big flooding problems for places that aren't very far above sea level.

The report in a magazine called Science says the experts have used new technology to measure changes in the amount of ice over the last 40 years.

Climate experts have predicted that sea levels could rise by as much as a metre in the next hundred years.
