  Experts worry about Antarctic ice melting
Updated 06 January 2003, 18.21
Experts are worried about glaciers melting
A team of scientists in Antarctica are trying to work out how big an effect global warming is having on the ice there.

And from their early research, the experts think the problems are worse than they feared, because the coastal ice is melting.

That might not seem too bad, but the coastal ice acts as a huge barrier in front of the glaciers.

Antarctica and Chile
If the barrier melts, the glaciers could be next.

And if that happens, the sea could rise much more quickly than at the moment.

The experts - from Chile and the space agency Nasa - are using top technology to try and do the biggest study of the ice ever.

They've only just started their research, and because there is so much ice it's going to take a long time to work out what all the information means.
