They’re more used to taking visitors to the reefs, but COVID-19 gave tour operators time to help check the condition of the corals. What they found doesn’t bode well.
If agricultural land was used to grow crops, it would limit methane emissions from livestock, but not store a substantial amount of carbon. Growing trees is what makes the difference.

Having a carbon price is linked to lower emissions growth. A larger price cuts emissions by more.
The Kangaroo Island dunnart was listed as critically endangered before fires ripped through 95% of its habitat. Those that survived the fires now face the threat of feral cats.
Scientists and bureaucrats moved logistical mountains to rescue the eastern bristlebird from bushfires this year. As climate change worsens, wildlife evacuations will become more common.
The story of the Kangaroo Island Micro-trapdoor spider offer insight into the challenges ahead for invertebrates – the tiny engines of Australia’s biodiversity – after this year’s cataclysmic fires.
The Kaputar rock skink is thought to have have one of the smallest ranges of any reptile in New South Wales – at the summit of a single extinct volcano, Mount Kaputar.
When the post-bushfire rains finally arrived, the situation for many fish species went from dangerous to catastrophic. A slurry of ash and mud washed into waterways, sending oxygen levels plummeting.
Electric vehicles are still relatively expensive but a trial to help them power the national grid in times of need could see owners being paid. That could make them a lot more attractive.
The last time global carbon dioxide levels were around 400ppm was four million years ago. On average, the world was 3°C warmer, but in high northern latitudes, it was up to 14°C warmer than today.
Koalas are notoriously difficult to detect. Traditional methods are costly and labour intensive. So we found a more efficient way to locate koalas in eastern NSW, using drones.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That’s always puzzled scientists, but now they think they know what happened.
