Mark Mattox has also been following this saga closely and conducted interviews both with the AWI and the ETC for this week’s edition of Living Planet, now available online.

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.
The Polarstern voyage around the North Pole
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?

Cool news from the Antarctic as preps for Alaska continue in German spring weather
Yesterday I read an interesting press release from the Alfred Wegener Institute, Germany’s polar research institute. It made the “panorama” page of our regional paper this morning. Their research vessel the Polarstern has just completed an Antarctic cruise and come up with the puzzling result that the deep sea in the Antarctic is actually getting colder. At the same time satellite images from the Antarctic summer have shown the largest extent of sea-ice on record. The question is whether this is the start of a new trend, or just a one-off. The last ARCTIC summer was the warmest on record. The trouble is this latest report on Antarctic cooling might make a lot of people think global warming isn’t a danger after all.

Meanwhile, here in Bonn, Germany,it is beginning to feel like spring. The tulips in my garden are in full bloom. After a long cold, wet spell, it looks as if it’s going to heat up in the course of the week – in time to make sure my transition to the Alaskan Arctic is a bit of a shock to the system.
I’ve decided to look out some of my favourite ice and snow pictures to put us all in the right mood.
“Cloud wisps over Ny Alesund”. This shows fjord and glaciers taken from the French-German Arctic research base in Ny Alesund on Svalbard, Spitzbergen last June. I was lucky to get a couple of days of this sort of weather. It’s more likely to be overcast. But even those days still have a certain charm. The colours look completely different, as in this pic:
This is me in my survival suit at the Kongswegen glacier, taken on the same trip. The photo was taken by Rainer Vockenroth, the head of the research base, which is run jointly by the French and the German polar research institutes.We went along the glacier in a small boat. The water was 2°C, which means you can become unconscious in five minutes – unless you’re wearing one of these uncomfortable but admittedly useful outfits.
