Why Africa has to worry about melting Greenland ice

Working for an international broadcaster which has Africa as one of its key target groups, I often find it difficult to interest some of my colleagues in what is happening in the Arctic. So my attention was caught instantly when I came across an article by Chelsea Harvey in the Washington Post: A climate chain reaction: Major Greenland melting could devastate crops in Africa.

Still cycling for the climate

I’ve just had a look at the Living Planet website and am pleased to hear that Amiram and Ragna are still cycling through Africa to draw attention to climate change.
They visited the Ice Blog at an earlier stage in their journey. Now they’re coming towards the end.

And the whole project is presented here:

Lions, Giraffes and Hippos on Ice ?



So what are these African animals (I took the pictures in Tanzania) doing on the Ice Blog? Of course it’s all about biodiversity.
The Arctic is particularly sensitive to climate change and acts as a kind of early warning system. At the same time, ice melting up there will have consequences for the whole planet. I’ve gone on a lot about how melting sea ice affects the flora and fauna in Arctic regions. There’s also been a mention of how melting glaciers change the temperature, salinity and light conditions of the ocean. I’m currently working on a radio feature on my trip out onto the sea ice up in the Arctic with the “ambassadors” from the Climate Change College and scientist Chris Petrich. (Listen out for that in Living Planet). One of the main subjects of his research is the “albedo effect”. That is all about how the whiteness of ice and snow reflects solar radiation back up off the earth’s surface. When the snow cover decreases, the “melt ponds” are a much darker cover, and that absorbs warmth – exacerbating the overall warming effect. So, polar areas have a huge importance for the planet as a whole. Then there is the methane (around 23 times more powerful than c02 as a climate gas) being released from the huge areas of melting permafrost.
All this effects not only the area where it happens, but the whole planet. And of course, the sea level is rising, which will have disastrous effects for all the low-lying areas of the globe.
All our species of plants and animals are dependent on particular habitats and living conditions – from polar bears to giraffes, hippos, kangaroos or cuckoos. (Listen to Alison Hawkes on the plight of the “bird of the year” in the Black Forest. Will cuckoos exist soon only in those quaint – or exasperating – clocks?)
The Cuckoo Story
Last night the IUCN and UNEP staged an event here in Bonn to mark Biodiversity Day.
More about the IUCN
During it, I met Pavan Sukhdev,who’s heading the TEEB project,that is a study on The Economics of Ecosystems and Biodiversity. I felt very privileged to have the chance to talk to the man who’s in charge of what some people say could do for biodiversity what Nicholas Stern’s report did for climate change. The idea is to put a price on nature and make it clear, in economic terms, what it is worth to protect our biodiversity. The first part of the report will be presented in Bonn next week, but he did give me an idea of the scale of things. You can read the interview here:
