July 9, 2016 — Governments must decide which parts of the Great Barrier Reef they most want to save and confront the prospect that some of it may be doomed, an expert on conservation modelling has warned.

Photograph: Thomas Schmitt/Getty Images About 90% of forests off the western coast were wiped out between 2011 to 2013, posing a threat to biodiversity and the marine economy, say scientists
July 7, 2016 — A hundred kilometres of kelp forests off the western coast of Australia were wiped out by a marine heatwave between 2010 and 2013, a new study has revealed.

April 30, 2016 — Al Gore has said the decision by Australia’s science agency CSIRO to cut climate research should be “re-evaluated at the highest level”, since they limit a source of critical information for the entire world as it attempts to solve the challenges posed by climate change.
