Scientists ‘stunned’ as Arctic sea ice shrinks to 30-year low

Ice in the Arctic has melted to its lowest level since record keeping began nearly 30 years ago, reaching a minimum area on September 16 that was 1.2 million square kilometres below the previous mark from 2005.

Scientists from the University of Colorado at Boulder's National Snow and Ice DataCenter said sea ice extent appears to have reached its minimum with the chances of it reaching a lower level unlikely this year.

“The amount of ice loss this year absolutely stunned us, because it didn't just beat all previous records, it completely shattered them,” said senior scientist Mark Serreze.

Earlier, Environment Canada reported that last summer was the seventh-warmest on record, with temperatures 0.9 C higher than average. Canada's all-time high was 1.8 C above normal in 1998.

The Amazon rainforest is magnificent. Watching programs about it, we’re amazed by brilliant parrots and toucans, tapirs, anacondas and jaguars. But if you ever go there expecting to be overwhelmed by a dazzling blur of activity, you’ll be disappointed. The jungle has plenty of vegetation — hanging vines, enormous trees, bromeliads and more — and a cacophony of insects and frogs. But much of the activity goes on at night or high up in the canopy.

Films of tropical forests don’t accurately reflect the reality of the ecosystems....
