Introduced species and diseases can drive native species into smaller environmental niches – and that could mean change to how we work to conserve them.

Australia is approving coal mine expansions because of their “very small” impact on global heating. It doesn’t stack up.
We used to focus just on protection of vital ecosystems like the reef. But as climate change and other threats accelerate, we need to actively help nature get ready for the heat.
In recent years, the Barrier Reef has had a reprieve – and coral has regrown strongly. But now the reprieve looks to be over and the heat is back on
It may soon be possible to reduce cyclone formation and intensity by spraying particles into the atmosphere above a forming storm. But the technology opens up a can of worms
We’re having a big impact on the planet. But what marks will we leave behind in deep time?
Climate change is ramping up, and with it, so is the rhetoric for action. It’s a fine line to walk between sounding the alarm and being accused of alarmism.
Incrementalism and politics as usual cannot save the Barrier Reef from the largest threat it faces – the heat ramping up from climate change
Sydney’s 14 wastewater treatment plants could be modified to also accept food waste, research shows. The ‘anaerobic digestion’ process would produce energy as well as nutrients for reuse.
As the drive towards electrification advances, one fact seems clear: it is far easier to reuse waste heat for our homes and businesses than it is to generate it anew.
Deep sea metallic nodules could help us shift to clean energy. But we don’t know how much damage it will do to ecosystems
20 years ago, solar and wind were expensive enough to make nuclear seem like an option for Australia. With cheap renewables a reality, there’s simply no point to domestic nuclear.
We’ll need some new transmission lines to make Australia’s grid ready for the green energy shift. But there are clever ways of making more use out of our existing network.
China is a major investor in Latin America’s renewable energy and critical minerals like lithium, but countries like Chile are also taking steps to secure their own clean energy future.
A new report from the Grattan Institute shows most households can save thousands of dollars by getting off gas and switching to electric appliances.
The likely El Niño is bad timing for the electricity sector, and means Australians may face supply disruptions and volatile prices.
The diet industry’s reliance on the ‘calories in, calories out’ concept is why society blames people for being overweight. But it’s a myth.
An expert in atmospheric science sheds light on Earth’s energy imbalance and its consequences for humankind.
Congress passed and the president signed the deal just days before the US was expected to default on its debt.
If we put green hydrogen plants next to green iron and steelmaking, we can clean up steelmaking and boost the hydrogen industry.
