This week’s Arctic news has been pretty drastic. The current autumn temperature is five degrees higher than the average. 2007 was the warmest year ever in the Arctic, since people started to record the temperature. The sea ice, as we know, has decreased dramatically.
This is all based on figures from NOAA, the US climate research body (National Oceanic and Atmospheric Administration).

The Polarstern (translates as Pole Star), the research vessel belonging to the German polar agency AWI (Alfred Wegener Institute for Polar and Marine Research) returned to base after being the first research vessel to sail right round the north pole because the north-west passage was open as well as the north-east.

White ice and snow reflect heat back into the atmosphere. Water,open because the ice has melted, is darker and absorbs heat, warming the ocean further. The Arctic is heating up at an alarming rate.
“Rudy” sent a comment in to the Ice Blog. He still isn’t convinced about global warming, it seems. I’m still trying to understand how that can be and what his point of view is.
Rudy, forgive me for not publishing the comment, but it contains abridged quotes from people without the context. Without being able to check the context, I can’t put them up here.
I’m happy to pick up on some of your points, though.
You’re right. Thankfully, the Arctic was not ice-free in 2008.(I didn’t think it would be, neither did most reliable sources I follow). But sea-ice cover hit a record low in 2007 and is not recovering. The North-West passage has been open. And the warming trend is continuing. Changes in flora and fauna are being witnessed and recorded. This is happening. And things are changing fast.
You say winds and circulation are causes of sea-ice melting, not global warming. Sure, winds and circulation play an important role. Nobody would dispute that. But these factors are all connected. And the climate is changing. I’ve talked to scientists from all over the world who are desperately trying to make predictions for the future. Nobody has a crystal ball. But we know humankind is pumping masses of CO2 into the atmosphere, melting permafrost is releasing methane, an even more powerful greenhouse gas, into the atmosphere at an increasing rate. Of course there are natural climate cycles. But we are having our own effect.
I was talking to some British friends this weekend, who suggested we should really get away from the misleading “global warming” talk and refer to “climate change”. Apart from the jokes about the British wanting warmer weather anyway – of course climate change manifests itself in colder weather in some places at some times. Is it just the “global warming” term that bothers you?
What bothers me right now is that our EU countries are thinking about reducing their commitment to climate-saving measures because of the global financial crisis. If we don’t take action now, we might not have a globe we can live on, let alone finances to worry about.
I wish someone could convince me that’s too pessimistic?

Is the Arctic Fridge becoming a Heater?
I’ve just come back from the studio where I was recording an interview with Dr. Martin Sommerkorn, Senior Climate Advisor with WWF’s Arctic Programme.
He was talking about the drastic decline of Sea Ice in the Arctic. It seems set to reach its lowest ever, and he tells us the scientists are desperately trying to revise their models to reflect this. “Reflect” is an appropriate word, because the most worrying thing is that white snow and ice reflect the sun’s heat back up off the earth, keeping the planet cooler. Darker water, on the other hand, absorbs it, heating up the planet further.
He says the Arctic could soon stop acting as a fridge that cools the planet and become a heater.
He explains it very well, so here’s the interview for a listen.
There will be a longer version available later in the week. I’m keeping it short here because it not everybody has broadband and a fast computer.

Climate Change threatening Arctic Seed Vault
I heard one piece of news this week which shocked me – and it worries me that it didn’t make its way into most of the media.
Earlier this year, the Global Seed Vault was opened on the Norwegian Arctic island of Spitsbergen. The idea is to store seeds of all the earth’s important plants, so that if we should experience any kind of major catastrophe, from nuclear explosions to mass epidemics or – yes – climate change, there could be a new start with the seeds from this bunker. It’s built into a hill, supposedly covered with permafrost.The seeds have to be kept between minus 18 and minus 20 degrees C.
But the vault hasn’t even survived one polar summer, with temperatures on the rise. The permafrost has partially thawed and the entrance tunnel to the vault has been damaged.
The Global Seed Vault management seem to be playing this down and say they’ll just have to use the bunker’s cooling system more often. But surely, that’s not quite the point?

Alaska baking faster?
This was us in Barrow just two weeks ago.
This morning, this email reached me from George Divoky, our ornithologist friend, observing climate change as part of his work monitoring a black guillemot colony on the Arctic’s Cooper Island:
“Was able to follow your travels via the B&J website and your blog and it looked like you were able to see some impressive examples of climate change in Alaska.
I was impressed with both the quality of climate change ambassadors and the media traveling with them. I tend to be skeptical of much of what is said and done to bring climate change issues to the public but found this exercise to be a good one and was glad I could become involved.
(…) I head off to Alaska in a week and Cooper Island about a week after that. After the late and snowy spring (which you know about first hand) things have gotten very hot there (5 C as I write this) and the snow all melted in the past two days.

Cool Forecasts – a Hot Topic?
They have no doubt that the planet is warming: Arctic explorers Marc Cornelissen,head of the Climate Change College, and archaeologist Anne Jensen, who rescues historic burial sites from being washed into the sea as a result of coastal erosion. (The sea ice is a natural protection barrier. As it diminishes, the land is left more vulnerable to the elements). I took the photo at Point Barrow, the northernmost point in the USA and well into the Arctic Circle.
People here in Germany are talking about a new study published in the journal Nature last week suggesting a possible lull in man-made global warming. (More in the “eco-news” bulletin which Nina Haase wrote for this week’s Living Planet programme):
Scientists and politicians are worried that this might make people think they don’t have to rush to take action after all. The study doesn’t dispute the human role in global warming, but it predicts a cooling down from recent average temperatures between now and 2015, as a result of a natural and temporary shift in ocean currents. Now, experts on the Intergovernmental Panel on Climate Change are worried that people might become relaxed again about reducing emissions. There’s no doubt about the fact that people are more likely to take action if they see clear evidence of climate change and are worried about droughts and floods.
(Ines, I thought of you this morning when I read in the paper that Barcelona is relying on tankers bringing in drinking water.)
I was on a panel at an event here in Bonn today where some of the journalists – discussing the role of the media in reporting on climate change – said doubt had been cast on the methods used in the “cooling” report anyway.
In the hope that it might convince some more undecided readers of this blog (I realize of course I could be preaching to the converted with this), I’d suggest a listen to George Divoky, a dedicated ornithologist working on Cooper Island, in the Beaufort Sea north of the Arctic town of Barrow. George has been observing guillemots for 33 years and has quite clearly seen the evidence of climate change. The interview is attached for your listening pleasure. It’s also featured in our Living Planet programme this week.
This shows climate ambassador Cara, talking to a young eskimo,Kayan, who told us he is very concerned about the warming climate and the changes to the sea ice on which the eskimo culture depends so much. Cara is also on this week’s Living Planet programme.
Trying to look at ancient burial sites at Point Barrow. This shows typical everyday working conditions for scientists and other experts trying to keep track of coastal erosion and the ancient sites in danger of disappearin there.
