Climate Change in the Arctic & around the globe

The Arctic headlines that weren’t?

Although I’m a journalist myself I still often find myself wondering why some things make it into the headlines with some media and others don’t. Sometimes you hear something in the news in the morning that disappears very rapidly. And sometimes, especially if you’re interested in and concerned about climate change, you read and hear things that shock or worry you then, again, don’t make it into any other media.
I have a couple of examples here. The first I can find an explanation for, although I don’t find it justified and hope the situation will change in the next few weeks.
Scientists from one of Germany’s most renowned scientific institutes, the Leibniz Institute for Marine Sciences at Kiel University, set off on an Arctic expedition today.They’ve joined forces with Greenpeace. The Greenpeace ship Esperanza is transporting some giant “test-tubes” up to the Svalbard archipelago, where they’ll be lowered into the water to look into the effects of climate change on the marine ecosystems. The scientists are particularly interested in the acidification of the oceans. I’ll be writing more about this later – in fact I’ll be catching up with the team and finding out more first-hand. But the reason I’m mentioning it today is that when I searched the news agencies, I didn’t find anything in English about this venture, although it’s using new, unique technology, and we know how susceptible the Arctic is to climate change – and what a key role it plays in regulating the world’s climate. I assume the reason is the ship left from the German port of Kiel, so only attracted German media. But come on folks, this is not a German story, the implications are as global as you can get.
I wasn’t able to go up to Kiel for the launch, but one of my colleagues went, so I’ll have more on that soon.
The other story which is even more worrying is one I came across in the online version of the German news magazine Focus
It’s headlined (in German)”Melting poles: No Ice, No Summer”.
The article reports on a story in the magazine Science which warns of the dangerous effects of melting ice in the Arctic and Antarctic on the deep ocean currents which help regulate the climate. In a highly over-simplified nutshell, it seems possible that at some point in the future, melting fresh water from the glaciers could reduce the salinity of the sea-water to the extent where the pump effect of dense salt water sinking into the depths would be hampered. This could interrupt the flow of warmer water which helps keep the climate of the British isles, southern Scandinavian and part of northern Germany mild.
Now why am I finding it difficult to get any more information on this from other media?

Volcanos, the “No-fly”- ban and the climate

None of the experts were keen to give an interview at this stage about a possible link between a warming planet and increased volcanic activity, although some certainly say it’s worth looking into. But as we know, these things take a long, long time and we humans tend to want results “now” – and certainly in our lifetimes. Felicity Liggins,a climate consultant with the UK met office.
Met Office Climate Change Guide
did answer my enquiry, explaining that there is some evidence from the geological record of a potential link between changes in climate and volcanic activity through changes in land ice. But the data and the level of scientific understanding of all this is still very limited, she says, so that it’s not possible to draw any firm conclusions about whether we could expect more things like this to happen as a result of human-induced climate change.
She refers us to the papers I mentioned in the last post, which look at the impact of climate-induced ice unloading on volcanic activity. The authors use examples from Iceland.
Now of course the huge impact and publicity caused by the volcanic eruption make it a fine time to draw the attention of a wider public to research like this, which might otherwise only interest a very small minority. I certainly find the topic worthy of note and would be happy if the Icelandic eruption and associated publicity leads to some more research into this.
Another “positive” thing to come out of the flying ban is the amount of CO2 emissions we saved, although given the current frenzy to make up for it, the question is how high the reduction will really be overall.
I interviewed Jan Burck from Germanwatch about this.


You can see from the picture in the background that the organisation is concerned with “North-South” dialogue and creating a fairer world.
Germanwatch
Jan took the emissions from European airtraffic per day, which amounts to an estimated one million tonnes of CO2. Taken over a whole week, he says those cancelled flights would have saved approxiamately one percent of Germany’s annual emissions, or as much as a whole country the size of Latvia emits in a year. That is a lot of CO2.
Maybe this whole crisis has made a lot of people think twice about flying, the form of transport most harmful to the climate. Estimates by Germanwatch and others say travelling just 3,000 km by air emits one tonne of CO2. By car, you could cover 7,000 km, by train between 15 and 20,000 km before producing the same amount. (Of course there are very complex calculations behind all this).
Jan Burck hopes big companies might re-think their travel policy, encouraging staff to use the train inside Europe, for instance. He also made the point to me that being “grounded” can give us a feel for distance and the size of the planet that a lot of people have lost, because air travel takes us across such big distances so quickly. Nice point Jan, good food for thought.

Climate and Volcanic Activity

I have been trying to pin down some elusive scientists this morning after reading a short article entitled “Research call to study climate link” on a double-page spread in the Guardian newspaper entitled “Volcano chaos”.
It quotes scientists in a series of papers published by the Royal Society calling for wide-ranging research into whether rising global temperatures could trigger more volcanoes, landslides, earthquakes or tsunamis.
Guardian online article The article says experts say global warming could affect these kinds of geological developments because it can move large amounts of mass on the planet’s surface. It seems logical that melting glaciers and rising sea levls would shift the distribution of huge quantities of water and that that could change pressure on the ground, possibly influencing ruptures or seismic shifts.
The paper quotes “research from Germany” as suggesting the earths crust could sometimes be close to moving so that quakes could be triggered by even tiny changes in surface pressure, e.g. from heavy rain. So far, my attempts to locate these German researchers this morning have been in vain. Ideas welcome.
Of course there are those who would say some of us are just obsessed by climate change and trying to relate it to everything. But if some scientists who have been looking into the distant past and think they can discern some evidence of significant warming being linked to geological activity then, it would seem foolhardy not to consider the possibility and feed the info into models for the future.
Meanwhile, that Icelandic volcano could be doing something for the climate by stopping all those planes from flying. I’m trying to get some figures on that. If I do, I’ll keep you posted.

Climate change as the ultimate in unsustainable development?

Your ice blogger was asked to write an editorial post for the ThInk3 website.It’s part of an EU blogging competition, which might interest you.
It’s all about development – in my opinion climate change and development are inextricably linked. Ice blog readers might find the site interesting in general – (and of course I’d be interested in your opinions on the guest editorial).

Polar publicity stunt?

I took this photo during a visit to the Arctic research station in Ny Alesund, Svalbard, during a visit in 2007.
Picture Gallery on Polar Research on Svalbard
I had a kind of deja vu feeling when I saw the place on a tv programme the other night about polar explorers, still very much in action today. This was the mast where Roald Amundsen’s airship was tethered before he set out to make the first flight over the North Pole in 1926. The latest of his successors in the line of polar explorers also set off from Svalbard (a different spot)to cross the North Pole in a balloon last week and made it at the weekend. The French explorer Jean-Louis Etienne had to land in eastern Siberia instead of Alaska as planned, because a snowstorm near the North Pole made it impossible for him to recharge
the balloon’s batteries, run from solar panels.
It’s quite an achievement to cross the Arctic, five days on your own in a balloon. The technology available these days has advanced somewhat from Amundsen’s days. Still, the Arctic conditions are pretty extreme and can still thwart the “best laid plans of mice and men” (Robert Burns). But Monsieur Etienne wasn’t just in it for the thrills. He was also measuring CO2 levels for some French scientific institutions. I wonder what he found out.
