Coral bleaching in Indonesia takes a turn for the worst:
The Wildlife Conservation Society has released initial field observations that indicate that a dramatic rise in the surface temperature in Indonesian waters has resulted in a large-scale bleaching event that has devastated coral populations. The initial survey carried out by the team revealed that over 60 percent of corals were bleached.
“Bleaching” — a whitening of corals that occurs when algae living within coral tissues are expelled — is an indication of stress caused by environmental triggers such as sea surface temperature fluctuations. Depending on many factors, bleached coral may recover over time or die.
The event is the result of a rise in sea surface temperatures in the Andaman Sea — an area that includes the coasts of Myanmar, Thailand, the Andaman and Nicobar Island, and northwestern Indonesia. According to the National Oceanic and Atmospheric Administration’s Coral Hotspots website, temperatures in the region peaked in late May of 2010, when the temperature reached 34 degrees Celsius — 4 degrees Celsius higher than long term averages for the area.
“This is a tragedy not only for some of the world’s most biodiverse coral reefs, but also for people in the region, many of whom are extremely impoverished and depend on these reefs for their food and livelihoods,” said WCS-Marine Program Director Dr. Caleb McClennen. “It is another unfortunate reminder that international efforts to curb the causes and effects of climate change must be made if these sensitive ecosystems and the vulnerable human communities around the world that depend on them are to adapt and endure.”

A very sad news bulletin, the likes of which we are going to have to start getting used to it seems.
Thanks for sharing the info Ove, even though it disturbs me greatly.
