What if whales took us to court? A move to grant them legal personhood would include the right to sue

Mon, 2024-04-15 06:18
If a new declaration based on customary concepts of tikanga and mana is recognised by the courts, it could potentially give interest groups the legal standing to sue on behalf of whales.

Why an intention to conserve an area for only 25 years should not count for Australia’s target of protecting 30% of land

Thu, 2024-04-11 14:31
Proper biodiversity conservation requires long-term commitments to protect areas of land and water, as laid down in international guidelines. James Fitzsimons, Adjunct Professor in Environmental Sciences, Deakin University Licensed as Creative Commons – attribution, no derivatives.

Roads of destruction: we found vast numbers of illegal ‘ghost roads’ used to crack open pristine rainforest

Thu, 2024-04-11 06:12
What harm can a road do? Plenty. Once built, illegal roads let loggers, miners, poachers and landgrabbers into the jungle, and the felling begins.

The heat is on: what we know about why ocean temperatures keep smashing records

Thu, 2024-04-11 06:12
Heat is surging in the world’s oceans. Climate change and El Niño explain part of it – but not all.

Adelaide is losing 75,000 trees a year. Tree-removal laws must be tightened if we want our cities to be liveable and green

Wed, 2024-04-10 12:48
South Australia stands out as having the weakest tree-protection laws, but cities around the nation are losing tree cover at a time when climate change makes them more important than ever.

The limits of ice: what a 19th century expedition trapped in sea ice for a year tells us about Antarctica’s future

Wed, 2024-04-10 06:16
In 1898, a pioneering Antarctic expedition was stuck in sea ice for over a year. In 2024, that area is open water.

Flash droughts are becoming more common in Australia. What’s causing them?

Tue, 2024-04-09 11:04
Recent flash droughts in parts of NSW and Victoria appeared quickly and can be followed by intense flooding rains. It’s part of a global trend driven by global warming.

Heat from El Niño can warm oceans off West Antarctica – and melt floating ice shelves from below

Tue, 2024-04-09 06:11
El Niño can direct more warm water to the base of West Antarctic ice shelves, accelerating melting and increasing global sea level.

Antarctica’s sea ice hit another low this year – understanding how ocean warming is driving the loss is key

Tue, 2024-04-09 06:11
Ocean warming seems the main driver of Antarctica’s sea-ice loss. But as satellites show, the change is not universal and sea ice persists in East Antarctica and the Weddell Sea.

The Southern Ocean has the cleanest air on Earth. We have just discovered why

Fri, 2024-04-05 12:04
A lack of human activity in the Southern Ocean is just one reason why the air is so clean. Clouds and rain play a vital role in scrubbing the atmosphere, removing natural airborne particles too.

Why artificial submarine curtains won’t save West Antarctica’s retreating glaciers

Wed, 2024-04-03 10:56
Geoengineering proposals to cool the ocean would indeed reduce ice loss from West Antarctica’s glaciers, but not enough to stop sea-level rise or allow the ice sheet to regrow.
