Dr. Stephen Jameson recently published a provocative essay in the Marine Pollution Bulletin that has stimulated considerable debate among reef scientists and conservationists, especially on the coral list server. His goal was to drill down to the ultimate social/political cause of reef decline, beneath the proximate environmental causes reef scientists study:
The real root cause of [...]
The Age is reporting on an open letter to the Australian Prime Minister Keven Rudd, urging the PM to make strong cuts in Australia’s greenhouse gas emissions by 2020. The letter, written by myself and 15 other Austalian scientists who contributed to the IPCC report, was released on the eve of the final [...]
Sorry for the bad pun… These great images were captured by photographer Chris van Wyk in Queensland, Australia (the green ‘mohawk’ effect, remniscent of the British subculture of the early 1980′s is actually an ephiphytic turf algae growing on the shell and head of the turtle). The Mary [...]
A comprehensive report released today by the Global Carbon Project contains the grim news that global CO2 emissions are exceeding the most pessimistic IPCC emissions scenario. The annual mean growth of atmospheric CO2 increased from 2.0 ppm (parts per million) during the first half of the decade and from 1.8 ppm in 2006, to 2.2 ppm in 2007. This increase in the [...]
The study by Graham et al. indicates that marine reserves have no effect on coral resilience to ocean warming.
Sydney Morning Herald, 22nd September, 2008
THE fraught political battle over logging in native forests is set to be re-ignited with the former Labor premier Bob Carr writing to the Prime Minister and senior ministers arguing that protecting the forests is “fundamental” to fighting climate change.
In a letter to Mr Rudd, [...]
“Ancient reef found in outback” (Courier News, September 22nd, 2008)
AN ancient underwater reef discovered in Australia’s outback could unlock the secrets of the world’s climate change history, scientists said.
Located in South Australia’s Flinders Ranges, the 650-million-year-old reef existed during a period of tropical climate between two major ice age [...]
An article published in PLoS One has huge implications for almost everything we do in our research on corals. In summary, using an array of genetic markers, a highly respected group of leading scientists including Fukami, Chen, Knowlton and others have shown that whilst Scleractinia (the stony corals) have a single origin in evolution, [...]
Local protection can make reefs resilient to the impacts of global change – Nancy Knowlton
Here are some underwater photographs taken at a recent field trip at Magnetic Island, inshore Great Barrier Reef. These reefs are usually highly turbid, based 8km away from the Townsville shoreline. I’m often suprised at the diversity and high cover of some of these inshore reefs, and [...]
