The unprecedented bushfires devastating swathes of Australia have already pumped out more than half of the country’s annual carbon dioxide emissions in another setback to the fight against climate change.
Fires blighting New South Wales and Queensland have emitted a combined 306 million tons of carbon dioxide since Aug. 1, which is more than half of Australia’s total greenhouse gas footprint last year, according to Niels Andela, an assistant research scientist at NASA’s Goddard Space Flight Center in Maryland and collaborator with the Global Fire Emissions Database. That compares with the Copernicus Atmosphere Monitoring Service’s estimate of 270 million tons in just over four months.
Rhinos in Australia might seem like an insane proposition – after all, we’ve had historically bad luck with introduced species. But on reflection it’s not quite as crazy as it sounds.
The Great Barrier Reef is being given a A$500 million ($379 million) boost by Australia in the battle to save the world’s largest living structure as it faces mounting challenges such as climate change, agricultural runoff and a coral-eating starfish.
A species of marsupial, the eastern quoll, has returned to the wild in mainland Australia for the first time in about half a century.
Scientists at the Australian National University have come up with a simple equation to calculate the impact of human forces on planet Earth. The numbers suggests humans are accelerating climate change by a factor 170 times greater than natural forces.
Human-caused climate change appears to have driven the Great Barrier Reef’s only endemic mammal species into the history books, with the Bramble Cay melomys, a small rodent that lives on a tiny island in the eastern Torres Strait, being completely wiped-out from its only known location.
It is also the first recorded extinction of a mammal anywhere in the world thought to be primarily due to human-caused climate change.
New research out of the University of Queensland confirms what many fishermen likely already suspected — the fish near angling hotspots are smarter.
