Rising carbon snuffs coral

In a large experiment on Australia’s Heron Island, the team simulated CO2 and temperature conditions predicted for the middle and end of this century, based on current forecasts of the world’s likely emission levels and warming by the Intergovernmental Panel on Climate Change (IPCC).

The results of their analyses of the bleaching, growth and survival of a number of organisms including corals indicates that a number of very important reef builders may be completely lost in near future.

“We found that coralline algae, which glue the reef together and help coral larvae settle successfully, were highly sensitive to increased CO2. These may die on reefs such as those in the southern Great Barrier Reef (GBR) before year 2050,” says Dr Anthony.

As Ove Hoegh-Guldberg is one of the researchers involved, Andrew Bolt will no doubt dismiss this. And, I have to admit, I think Ove does tend to the most pessimistic interpretation of anything that affects coral.

However, I am still concerned that he is right on the long term prospects.
