less coral reefs

………………………………….

Coral reefs will be the first global ecosystem to collapse in our lifetimes. More than 450 scientists from over 60 countries are participating in the “Effects of Climate Change on the World’s Oceans” symposium. When CO2 in the atmosphere reaches a concentration of 450 to 500 parts per million (ppm), the oceans will mostly be too acidic for corals to grow.

more coral reefs

Coral reefs could be growing 35 per cent faster by the next century because of global warming. A team from the University of New South Wales, in Sydney, modelled interactions between the atmosphere, oceans and ice and found that warmer water would increase the rate of coral calcification, outweighing the detrimental effect of lower calcium carbonate levels. By 2100, corals would be growing 35 per cent faster than they do today, they predicted.
