Using a world-first scientific discovery, Australian researchers are developing a stress-test for coral, to measure how coral reefs are being impacted by pressures from climate change and human activity. The scientists have found hemoglobin genes in the microalgae which live symbiotically with coral, which may provide a readout on how stressed a particular coral is — and how likely it is to bleach and die. Coral bleaching occurs when the symbiotic algae abandon the coral due to...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have discovered corals at Australia´s Great Barrier Reef at depths that were previously believed to be uninhabitable. A team of researchers with the University of Queensland's Seaview Survey has been working on a multi-year project to map out the Great Barrier Reef, and they recently announced that they have found corals in waters nearly as dark as night. The newly discovered corals sit at 410 feet below the surface at...

Coral Reefs Will Suffer If Climate Change Goes Unchecked

Brett Smith for redOrbit.com - Your Universe Online Time may be running out for the world´s coral reefs which could be severely victimized by rising global temperatures and carbon dioxide levels, according to a new report in Nature Climate Change. "Our findings show that under current assumptions regarding thermal sensitivity, coral reefs might no longer be prominent coastal ecosystems if global mean temperatures actually exceed 2 degrees Celsius (3.6 Fahrenheit) above the...

Australian marine scientists have expressed disquiet over the continued worldwide spread of large, dead zones in the ocean. Professor Ove Hoegh-Guldberg and Professor Mark McCormick of the ARC Centre of Excellence for Coral Reef Studies have recently published scientific articles which raise concern about the impact of large areas of ocean emerging which are so low in oxygen that fish and other sea life cannot survive. Hundreds of dead zones are being reported around the world in areas that...

The first comprehensive synthesis on the effects of climate change on the world's oceans has found they are now changing at a rate not seen for several million years. In an article published today in Science magazine, scientists reveal the growing atmospheric concentrations of man-made greenhouse gases are driving irreversible and dramatic changes to the way the ocean functions, with potentially dire impacts for hundreds of millions of people across the planet. The findings of the report,...

The skeptics who frequently deny the reality of climate change in the world's media lack all scientific credibility, charge three eminent Australian researchers who have just been listed among the world's 20 most influential scientists in the field of climate change. Marine researchers Professor Ove Hoegh-Guldberg, Professor Terry Hughes and Professor John Pandolfi were ranked in the world's top 20 by the international science citation analysts Thomson Reuters and ScienceWatch, for the decade...

The rise in human emissions of carbon dioxide is driving fundamental and dangerous changes in the chemistry and ecosystems of the world's oceans, international marine scientists warned today. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," the researchers say in the latest issue of the journal Trends in Ecology and Evolution (TREE). "This emphasizes the urgent need to adopt policies that drastically reduce CO2...

To have even a chance of saving the world's coral reefs from extensive damage caused by global warming, carbon emissions in industrialized countries need to be cut by 25% below their year 2000 levels by 2020 "“ and by 80-90% by 2050. That is the uncompromising warning delivered today by some of Australia's most eminent marine and environmental scientists in a briefing to Australian Members of Parliament and Senators, in Parliament House, Canberra. "The Great Barrier Reef (GBR)...

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...
