The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica from the worst effects of
global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures
on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level
increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other
parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around
the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much
of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair
itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face
the full impact of global warming. This means an increase in average air temperatures of around 3OC and a
reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors
Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean
waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice
sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western
Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too
late. "Everything is connected-Antarctica may be a long way away but it is an important part of the Earth's
system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough,
if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because
of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.
