[Coral-List] NOAA Press Release - 3rd ever Global Bleaching Event Underway

I'm not qualified to wade into the debate regarding the significance of local stressors as contributing factors to widespread bleaching events, but I think that it is past due for the (marine) scientific community to put an emphasis on public awareness. The fact that it seems as if the media is finally beginning to consider the issue as newsworthy is in and of itself something of a victory. Instead of bickering, perhaps you should all take advantage of this opportunity to reach out to any and all media outlets and tell them your stories. Even if you are convinced that land-based pollutants and over-fishing play no part in global bleaching events, surely you consider them to be problematic and can find room to include something about these issues in your version of the narrative.
