Climate Change Impacts on Ocean Ecosystems
Posted on 8 February 2011 by John Bruno
I am posting an awesome talk by Dr. Ove Hoegh-Guldberg from a session Ove and I organized on climate change impacts on ocean ecosystems at the NCSE Our Changing Oceans meeting a few weeks ago in Washington, DC.
Session summary: Rapidly rising greenhouse gas concentrations are driving ocean systems toward conditions not seen for millions of years, with an associated risk of fundamental and irreversible ecological transformation. Changes in biological function in the ocean caused by anthropogenic climate change go far beyond death, extinctions and habitat loss: fundamental processes are being altered, community assemblages are being reorganized and ecological surprises are likely.
The speakers included myself, Ove, Dr. Mary O'Connor (an assistant prof at UBC) and Dr. Steve Gaines, the dean of the Bren School of Environmental Science and Management, at UCSB.
After the session Steve Gaines and I participated in a panel discussion on NPR's Science Friday about climate change and the oceans that you can listen to here. I think we may have even convinced Ira to call it ocean change, rather than climate change!
You can download many of the papers referred to in the talks here (including the Hoegh-Guldberg and Bruno Science paper on "The Impact of Climate Change on the World’s Marine Ecosystems" and several of Mary O'Connors papers).
