While the climate negotiations continue at a snail’s pace in Doha, marine snails or pteropods in the Antarctic are losing their shells because of ocean acidification. Researchers from the British Antarctic Survey (BAS) and partners have published the first evidence of ocean acidification affecting live marine creatures in the Southern Ocean. Ocean acidification is caused by the uptake of carbon dioxide from the atmosphere emitted as a result of fossil fuel burning.

I found the latest online edition of WWF Arctic‘s newsletter The Arc in my in-box today. For a Friday afternoon or weekend pastime, I would recommend a look. I was particularly interested in the item about polar bears on Svalbard, following the sea ice or locating a dead whale.  Having been on the Arctic island a few times it holds a special interest for me. And the chance to track polar bears moving around is absolutely fascinating. The bear tracker site does just that. There’s also a video of how researchers on the ground work with the bears. Can you imagine putting your hand between the jaws of a giant white bear?

Given the increased interest in drilling for oil and gas in the Arctic as the area becomes more accessible in a changing climate, concern is also growing about the dangers an accident could pose to the fragile environment of the “high North”.  An editorial in the publication NATURE argues that we need a binding agreement like the Antarctic Treaty to protect the Arctic from pollution.

Ice blog followers may remember my account of a visit to the Svalbard seed vault, which preserves a wide variety of seeds safe under the permafrost of an Arctic mountain for posterity. The story is also online at DW’s environment website.

The idea is that saving a wide diversity of crop seeds could help humankind survive in the future in spite of any disasters occurring – or, for instance, to help agriculture cope with the challenges of a changing climate.
Well the vault has just celebrated its third birthday with a bumper delivery of seeds from different parts of the world. For the first time ever, seeds have been delivered from Australia, just about as far away as you can get from the Arctic. Australia is one of the areas of the world that are particularly vulerable to climate change. It has had to cope with an increasing number of extreme weather events, droughts and floods. The seeds brought to Svalbard were the furthest travelled of the more than 600,000 samples now stored at the vault.
Most of Australia’s food crops come from outside the country, and so are dependent on global crop diversity.
There’s more information on the website of the Global Crop Diversity Trust. See also “Wild Relatives can save our food supply” on why it’s important to preserve crop seeds for posterity.

“He’s cute” – is the response I’ve been getting to this Svalbard reindeer, pictured at Ny Alesund earlier this year.
Well reindeer and I would like to wish all iceblog readers all the very best for the Christmas holidays. In case you won’t be reading again until 2011, I’ll wish you a happy new year when it comes. But I am planning to be posting again before the turn of the year.
But do take time now for a quick click to another blog I’d like to draw your attention to. I’ve just contributed a post and will do so again on occasion.
The Global Ideas Blog and the whole project is all about finding solutions to our climate problems.”Thinking for a cooler world”. What do you think?
All the best for now.
