The grisly discovery of a disembodied foot on a NSW beach was a tragic twist in the mystery of missing woman Melissa Caddick. Such tragedies can also reveal hidden currents connecting the planet.
Scientists previously underestimated aquatic methane emissions. We must use this new information to stop methane derailing our attempts to stabilise the Earth’s temperature.
Floodplains are among the most productive ecosystems on the planet – they are biodiversity hotspots. That's in large part due to periodic flooding between different parts of a river-floodplain system.
This Easter, read about this remarkable species of resurrection fern — plants that appear dead and dry, but under the right conditions rapidly spring to life.
Australia is considering removing humpback whales from the threatened species list after their numbers rebounded in recent decades. But the mammals face new threats.
This is not an imaginary future dystopia. It's a scientific projection of Australia under 3℃ of global warming – a future we must both strenuously try to avoid, but also prepare for.
New research shows nature started its long road to recovery in 2020 – especially in NSW and Victoria. But overall conditions across large swathes of the country remain poor.
Standard economic theory suggests solar exports shouldn't be taxed at all.
As bushfires become larger under climate change, the area exposed to intense and severe fires is likely to increase.
Our report draws on data from more than 1,000 participants who told us of their experiences through community meetings, repeated surveys years after the fires or in-depth interviews.
If Australia pushes ahead with producing fossil fuels, we may lock in a new high-emissions energy system, or one that's uncompetitive. Clearly, green hydrogen is the best way forward.
This autumn, embrace puddles. Even tiny pools of water can be essential for birds, trees and pets — from washing away chemicals on leaves to forcing worms to emerge.
With more people composting due to environmental concerns or council programs, they need to know how to do it right.
The environmental, cultural and scientific sensitivity of some sites, and rarity of some fossils, means amateur fossil collecting comes with huge risks.
We were supposed to have a 'climate election' in 2019. New research looked at attitudes to climate change in Australia, and may explain why that didn't pan out.
The NSW floods are a textbook example of the theoretical impacts we can expect on Australian rainfall as climate change continues.
Evacuation and relief centres are often the first place disaster-affected people go, and should provide a minimum standard of living and care. But this standard is not always met.
Climate change has long been dismissed as a significant stress to New Zealand's native wildlife, but research shows it exacerbates existing threats such as introduced predators and habitat loss.
Undersea shell middens contain important clues about the past - what people ate, who they were interacting with and how the climate was changing. Now we have a better way to detect and excavate them.
It's said the best predictor of future behaviour is past behaviour. Let's hope that's not the case with Mathias Cormann's climate stance when he joins the OECD.
As immunisation emerges as the world's primary weapon to combat COVID-19, much more work is needed to improve electricity access so vaccines can be refrigerated.
We used satellite images to study the life cycles of mangrove forests in the Northern Territory, Queensland, and New South Wales — and found a surprising degree of variation.
We hear a lot about the Morrison government 'kicking the can down the road' on emissions reduction. New research reveals the precise burden that forces onto young Australians.
In healthy populations, the song of regent honeyeaters is complex and long. But where the population is very small, the song is sadly diminished.
What was a feature of power stations such as Yallourn has become a bug.
