Australian marine scientists have issued an urgent call for massive and rapid worldwide cuts in carbon emissions, deep enough to prevent atmospheric CO2 levels rising to 450 parts per million (ppm).
In the lead up to United Nations Copenhagen Climate Change Conference Professors Charlie Veron (former Chief Scientist, Australian Institute of Marine Science) and Ove Hoegh-Guldberg of the ARC Centre of Excellence for Coral Reef Studies and The University of Queensland, have urged the world’s leaders to adopt a maximum global emission target of 325 parts per million (ppm).
“If CO2 levels are allowed to continue to approach 450 ppm (due by 2030–2040 at the current rates at which emissions are climbing), reefs will be in rapid and terminal decline world-wide from mass coral bleaching, ocean acidification, and other environmental impacts associated with climate change.”
At the same time CO2 emissions are turning the oceans more acidic, causing damage to corals and all life with a carbonate skeletons or shells and, if unchecked, potentially leading to mass extinctions of ocean life like those of the geological past…. Read Full Article
