[Coral-List] CO2 risks for coral reefs

[Peter Sale]

Steve and list,
Here are several links that report the story with varying degrees of precision and accuracy:
Business Standard (India) basically quotes the press release: http://www.business-standard.com/article/pti-stories/coral-reefs-doomed-even-if-cop21-is-wildly-successful-115081700535_1.html
Sydney Morning Herald uses the story to attack Rupert Murdoch (always fun): http://www.smh.com.au/environment/all-at-sea-with-rupert-murdoch-on-the-marine-environmental-crisis-20150817-gj0l9y.html
The Telegraph (UK) does reasonable job - will its denialist readers care?: http://www.telegraph.co.uk/news/earth/11809525/Coral-reefs-are-likely-to-disappear-from-the-Earth-despite-climate-change-talks.html
E&E Publishing (Washington DC) went a bit further and did well, engaging Mark Eakin to support/amplify the message (thanks, Mark): http://www.eenews.net/stories/1060023581
I saw only one article in Spanish which failed to mention the 350ppm recommendation, and generally suggested reefs are already f**ked and there is nothing we can do to fix them.  That was NOT my message: http://hipertextual.com/2015/08/arrecifes-de-coral

Not too bad overall, considering most journalists did not talk to me, or attend the talk.  But the articles do permit making more noise about the subject.
Thanks all,
Peter

Hi Peter - is there a link to a news story that covers these points that could be pointed to in a blog or tweet?

I agree with your points - reducing emissions is key. The U.S. targets announced by the President a fews weeks ago are a great emissions down payment - but not enough. And coral reefs as ecosystems will not long continue to provide shoreline protection and food for people under these conditions.

Specifically, I provided evidence that warming and acidification were already impacting reefs to a significant extent, increasing coral mortality rates and reducing capacity to grow and repair, and I reported on the loss of live coral cover on the GBR and in the Caribbean since the mid-1970s (from all stresses combined).

They will continue to degrade as warming and acidification will both increase through end of the century, and (in my opinion) by mid-century reefs of the quality that existed in the mid-1960s when I first started enjoying doing research on them, will no longer exist.  Instead we will have algae-dominated, rubble-strewn, slowly eroding limestone benches bearing a thin scatter of coral colonies eaking out a poor existence.

For a start, if every group 'managing' an MPA would commit immediately to real effort to implement the management strategies already on paper that would be a good start.

At the very least, we might be able to push the Paris process a little closer to a real solution than the responses of countries (such as my own) so far suggest will happen.
