Climate Change in the Arctic & around the globe

Greenland on the horizon

When I first visited Greenland back in 2009, it was not a place that made the news very often. This summer, as I prepare for another visit, I have been reading, hearing and viewing quite a bit about Greenland recently – and most of it was alarming.

Dark news from the white island

“Sea level fears as Greenland darkens” was the headline of a piece by David Shukman for the BBC. It reports on the findings of the “Black and Bloom” research project, looking at how increasing algae blooms through climate warming are darkening the ice sheet, meaning it absorbs more heat from the sun instead of reflecting it back into space.

Scientists are keenly observing the cracking of Greenland’s Petermann glacier. It has not made headlines on the same scale as the giant Larsen C iceberg in the Antarctic, but scientists tell us it is highly significant in terms of impacts clearly attributable to climate change. On Twitter, @Petermann_Ice provides regular updates. NSIDC provides daily information on the Greenland ice sheet in general.

Earlier this summer, a tsunami played havoc and caused loss of life in a small settlement on the west coast of the island. Ice melt is now thought to have played a key role.

Faraway Greenland a global concern

While I don’t grudge the beautiful ice island the media attention, the reason it has been making headlines  is a huge cause for concern. Climate change is melting the massive ice sheet increasingly fast, involving feedback effects which are hard to predict, and already affecting global sea level and weather patterns.

With this year’s UN climate conference, scheduled to be held right next to our DW headquarters here in Bonn, looming large on the horizon in three months time, I will be paying a visit to the icy island to see first-hand how climate change is affecting Greenland and the people who live there, and what scientists are finding out about the state of the northern hemisphere’s biggest body of freshwater. The massive ice sheet that (still) covers 80 percent of the world’s biggest island has the potential to increase global sea levels by 7 meters, if it were to melt completely.

Now while that extreme is not something I worry about happening any time soon, I am concerned that the ice is melting ever faster and already contributing more to sea rise than it used to, with clear consequences for low lying coastal areas in many parts of the world. Even that massive ice sheet, more than three kilometers thick at its highest point, which has covered Greenland for two to three million years, is not safe from our human-induced global warming.

Lucky for some?

Of course the Greenlanders themselves are experiencing considerable changes to the environment they live in. The sea ice they relied on has dwindled in summer, shortening the time when it can be used as a reliable platform for people to travel from place to place by dog sled or snowmobile. Thawing permafrost is creating problems for some buildings. Traditional hunters and fishermen are having to change their lifestyles.

At the same time, given the harsh conditions in Greenland, especially in winter, it’s not hard to understand why some Greenlanders are not too upset about the climate getting a bit warmer. Grow more fruit and veggies. Earn revenue from easier mining, shipping, drilling – maybe enough to fund complete independence from Greenland? The worries of small island states in the Pacific may well seem a world away. But there is no escaping the fact that melting Greenland ice is raising sea level and changing weather patterns all over the globe, even in unlikely places like Africa.

So – it’s time for the Iceblogger to get the gear ready. The ice island is getting warmer. But I won’t pack my bikini for this trip. There has been a lot of snow this summer. I hear the occasional sceptic saying, “see, more snow. Where’s your warming?” I am happy to refer them to expert Jason Box:

low surface ice loss on Greenland this year due to heavy snowfall – consistent with climate warming

Climate Central also takes up the subject.

Yes, climate warming is in this case resulting in more snow. At least the field reports from “Eastgrip”, the East Greenland Ice-Core Project, tell me that means there are fewer mosquitos around. Think positive.

I will be heading first to Kangerlussuaq, the departure point for expeditions to the ‘”inland ice” of Greenland at the weekend. Look out for a post from there some time soon.
