Antarctica

Ice-melting is often mentioned as one of the big signs of climate change already happening. ABC's Catalyst team recently did a special report on Antarctica, and the melting.


In summing up, reporter Paul Willis said "the ice is melting from above and below. When it comes to sea level rise, Antarctica the sleeping giant is waking up." But the most shocking quote came from NASA's Dr James Hansen.

Antarctica was losing mass at about 75 cubic kilometres per year, well that's now doubled to about 150 cubic kilometres a year. So that's beginning to worry glaciologists.

I can tell you it also worries a few people who aren't glaciologists - such as yours truly.
