NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

ARCTIC CHANGING FASTER THAN EXPECTED

Climate-change is transforming the Arctic environment faster than expected and accelerating the disappearance of sea ice, reports the biggest-ever study of Canada's changing north, which involved more than 370 scientists from 27 countries. Collectively they spent 15 months, starting in June 2007, aboard a research vessel above the Arctic Circle, the first time a ship has stayed mobile in Canada's high Arctic for a whole winter.

'(Climate change) is happening much faster than our most pessimistic models expected,' says David Barber, a professor at the University of Manitoba and the study's lead investigator.

Models predicted only a few years ago that the Arctic would be ice-free in summer by the year 2100, but the increasing pace of climate change now suggests it could happen between 2013 and 2030, Barber said.

The cost of the Arctic's rapid melt will be $US2.4 trillion by 2050 as the region loses its ability to cool the global climate, says the U.S.-based Pew Environment Group, which released a report showing the Arctic is warming at twice the rate of the rest of the planet.
