Green hydrogen could decarbonise entire industries in NZ – but there’s a long way to go

Mon, 2024-11-25 05:10
If New Zealand decided to use green hydrogen to decarbonise industries such as fertiliser and methanol production, it would need to triple the installed capacity of renewable power plants.

Humans are killing off the old and wise animals that hold nature together. Here’s what must change

Fri, 2024-11-22 05:07
Like big, tall trees in old-growth forests, older animals are irreplaceable. Pulling them out leaves the ecosystem less resilient to future shocks. It’s time for ‘longevity conservation’ measures.

COP29: ‘climate finance’ for the Pacific is mostly loans, saddling small island nations with more debt

Thu, 2024-11-21 08:44
The real beneficiaries of climate finance for small island nations are private contractors brought in to build resilient infrastructure. There are now calls for a fairer money dispersal system.

Could keeping native species as pets save them from extinction? Here’s why it’s not that simple

Tue, 2024-11-19 15:57
Why can’t you keep a wombat or koala as a pet rather than a cat or dog? There are good reasons why keeping native animals as pets isn’t as easy as it seems Meg Edwards, Lecturer in Wildlife Science, University of Southern Queensland Licensed as Creative Commons – attribution, no derivatives.

As Australia privatises nature repair, the cheapest approach won’t save our threatened species

Mon, 2024-11-18 12:33
Australia’s carbon credit scheme largely fails to protect threatened species, despite assumptions to the contrary. The findings provide cautionary lessons for the nature repair scheme.

Fri, 2024-11-15 05:23
New research reveals a third of Australia’s freshwater fishes are at risk of extinction. That means 35 species should be added to the national list of 63 threatened species, bringing the total to 98.
