Climate Change in the Arctic & around the globe

Mission accomplished – data worrying. The Arctic ocean acidification project

I have just heard that the experiment I reported on from Svalbard has been concluded. A press release from Greenpeace quotes Professor Ulf Riebesell from the IFM-GEOMAR Kiel Uni ocean acidification project as saying the experiment was a success.

(I took this pic of Prof. Riebesell watching the deployment of the mesocosms last month, see earlier posts).

That doesn’t mean the news is good:
“Not only do we now have the most comprehensive data set ever on the impacts of ocean acidification in Arctic waters, we have also learned from this experiment that ocean acidification in these waters has a definite impact on the base of the food web, which can have implications for the entire ecosystem.” says Prof. Ulf.
“If we keep emitting CO2 at the current rate, marine organisms will experience changes in ocean acidity beyond anything they have experienced in the last 20 million years of their evolutionary history.”
Worrying times indeed.
