Great barrier reef obituary goes viral, to the horror of scientists – ‘The message should be that it isn’t too late, not we should all give up’

[Although this obituary is cleverly written, the GBR’s situation is bad enough, and overstating it isn’t helpful. Nevertheless, this was possibly the GBR’s worst year in its 600,000 year history, with 22 percent of the reef totally bleached. The inexorable trends in acidification and ocean warming suggest that we may still witness the death of […]

Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2

MIAMI, 12 September 2016 (University of Miami) – In a first-of-its-kind study, researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and the ARC Centre of Excellence for Coral Reef Studies at James Cook University showed that increased carbon dioxide concentrations alters brain chemistry that may lead to neurological impairment […]

350: Exxon killed the reef

25 August 2016 (350) – The seas of dead coral are a crime scene. This year, the world witnessed the most devastating mass coral bleaching event ever recorded which left behind dead reefs in at least 38 countries. Many of these reefs will never recover. The immediate cause is clear: the ongoing rise in global […]

Climate change pledges not nearly enough to save tropical ecosystems

By Jeremy Hance16 August 2016 (mongabay.com) – The Paris Agreement marked the biggest political milestone to combat climate change since scientists first introduced us in the late 1980s to perhaps humanity’s greatest existential crisis. Last December, 178 nations pledged to do their part to keep global average temperatures from rising more than 2 degrees Celsius […]

‘The blob’: how marine heatwaves are causing unprecedented chaos in ocean ecosystems

By Michael Slezak14 August 2016 (Guardian) – First seabirds started falling out of the sky, washing up on beaches from California to Canada. Then emaciated and dehydrated sea lion pups began showing up, stranded and on the brink of death. A surge in dead whales was reported in the same region, and that was followed […]

NOAA scientists report mass die-off of invertebrates at East Flower Garden Bank in Gulf of Mexico

Great Barrier Reef suffers complete ecosystem collapse after record ocean heat wave – Bleaching event is ‘much more extreme than we’ve measured before’

By Dominique Mosbergen25 July 2016 (Huffington Post) – It’s been a wretched year for Australia’s Great Barrier Reef, the largest living structure and one of the most complex natural ecosystems on Earth. The area suffered the worst bleaching event ever, one that impacted over 90 percent of the reef and killed more than a third […]
