Is Australia shooting itself in the foot with reef port expansions?

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.

Increasing coal exports will play a significant part in the decline of the Great Barrier Reef, and will prove to be a very uneconomical decision for Australia. Continue reading “Is Australia shooting itself in the foot with reef port expansions?”

Scientists predict US$2trn cost to ocean economies

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.

The scientists are now calling for a global, integrated approach to protect oceans from converging threats.

Revealing the oceans

“The visual nature of the project will also help bridge the gap between scientific knowledge and public awareness,” Professor Hoegh-Guldberg

Press release, University of Queensland,

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.

The Catlin Seaview Survey, announced in Singapore today, aims to carry out the first comprehensive study of the composition and health of Reef coral to an unprecedented depth range (0-100m).  Continue reading “Revealing the oceans”

Pesticides and the Great Barrier Reef: Extensive new data and analysis and increased concerns (a note from Jon Brodie)

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:

Bolt distorts facts about the Great Barrier Reef again: doesn’t understand or wilful distortion?

Update: Andrew Bolt is at it again.  Either he doesn’t understand the science or he is wilfully distorting the information surrounding the impact of climate change on coral reefs.

See also this previous posting (Bolt gets it wrong again) and this post on record mass coral bleaching occurring right now off Western Australia.

Update: this piece was first published back on Feb 10th, 2009 – I thought it would be worth bringing up to the top to highlight Bolt’s ongoing war against science. Continue reading “Bolt distorts facts about the Great Barrier Reef again: doesn’t understand or wilful distortion?”

Climate Change Will Lead to the Extinction of Coral Reef Fish

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
