My sincerest apologies for wasting time and bandwidth with what Im sure
is an eye-rolling question for you all.
I have tried to answer this question myself but have found
to back up my response.
Can anyone help me ?
"Why are marine biologists so worried by a forecast global warming
rise of 1.4-5.8 degrees occurring over the next century, when the
coral obviously survived a far more rapid and greater increase (~7
deg over 10 years) about 15000 years ago (Younger Dryas) ?"
My response is this:
1. Greenland never had hard corals and the temperature change was
probably local not global.
2. Just because some corals survive, doesnt mean losing massive
diversity was a minor effect.
3. Tropical coral reefs have been stable for a long time now - sudden
change will be disasterous.
But thats the best I can offer.
Hope someone out there has some patience.
