With the approval of dredging as part of the Abbot Point port expansion, Australia has given the green light to an increase in coal exports. While opposition to the plan has focused primarily on the effects of dumping dredge spoil near the Great Barrier Reef, climate change has been missing from the discussion.
Carmel Doyle, Siliconrepublic.com, March 22, 2012. Scientists at the Stockholm Environment Institute (SEI) have released a new study that has placed the effects of climate change on the world’s ocean ecosystems under the spotlight. They predict climate change alone could reduce the economic value of key ocean services by up to US$2trn a year by 2100.
A pioneering scientific expedition that will document the health of coral on the Great Barrier Reef will be undertaken as a joint venture between global technology giant Google, the UQ Global Change Institute, not-for-profit organisation Underwater Earth and insurance company Catlin.
As a result of an extensive research and monitoring program funded by the Queensland and Australian Governments over the last 5 years a greatly better understanding of the risks to Great Barrier Reef ecosystems from pesticide residues is now available and in the process of being published in the scientific literature. Most of the papers are or will be published in special issues of Marine Pollution Bulletin and Agriculture Ecosystems and the Environment. Some of the MPB papers are already published online and the rest from both issues will follow over the next few months. While the complete set is still uncertain (due to reviewing still in progress) the following are already out:
Dobu Island in Papua New Guinea has active underwater fumaroles (Jennifer Marohasy posted on it a few years back) that seep high concentrations of CO2 into the environment, in turn acidifying the surrounding ocean. These vents have been active for at least 50 years: according to village elders these seeps have existed at that location … Continue reading Bubbling sea signals severe coral damage this century
One of the many factors causing the global loss of reef building corals is anthropogenic climate change, which is slowly warming the world’s oceans. When summertime temperatures are warmer than usual, corals can die from “bleaching” and disease outbreaks. This in turn is devastating for the countless organisms that inhabit coral reefs. A new paper … Continue reading Climate Change Will Lead to the Extinction of Coral Reef Fish
