There are calls for Australia’s onshore gas to flow much more freely.
Rising gas prices and energy security issues have led to calls for more gas to be pumped into our energy system. But we need to balance that with the equally pressing need to limit greenhouse emissions.
As politicians debate the causes of South Australia's power failures, separating fact from rhetoric has become difficult.
Keep the climate in mind when you’re choosing what to plant.
Plant species are reacting to climate change by adapting or migrating to better conditions. But this is not an option for gardens, so gardeners will have to be smarter about what they plant and where.
Green shoots: a mangrove in Cairns enjoys the wet. Not all of Australia was so lucky.

Rain made a welcome comeback to Australia in 2016 after several years of deepening drought. But Tasmania and the Top End were among several places that did not fare so well.
Peak energy demand sometimes occurs when there’s no wind.
Here are some short- and medium-term strategies for transitioning to renewable, reliable and affordable energy in South Australia.
Australian voters rejected carbon taxation. But some US conservatives are now embracing it.

Taxing carbon has always been a tricky political sell for conservatives. But a group of establishment US Republicans is touting the idea of a carbon "tax and dividend" as a way to break the deadlock.
Industrial emissions have blown across Mount Isa for decades.

Glencore has admitted responsibility for air pollution in Mount Isa, but its latest report puts the onus on residents to minimise their exposure to lead contamination in their homes.
A strong, certain price signal could see the dawn of a new period of investment in renewables.
Labor has been criticised for vacillating about about its 50% renewable energy ambition. But its proposed emissions intensity scheme could boost green energy without any hard target at all.
There has been a rapid increase in the amount of resources tied up in buildings.
There will be huge environmental impact if we keep using raw materials as we did in the 20th century.
The rules were written at a time when coal and gas were the only major options.

Here's the real problem behind Australia's electricity woes: the rules that govern decisions about what infrastructure to build, and when, are inflexible and outdated.
The World Bank has highlighted steps to improve sustainable energy investment.
Australia is near the back of the pack of rich nations when it comes to policies for clean energy. But there are things we can do about it.
Emergency crews tackle a bushfire at Boggabri, one of dozens across NSW during the heatwave.
Heat records have tumbled across New South Wales as the state suffered through the weekend's heatwave. A new analysis shows that climate change made this kind of event much less of a rarity.
The Flinders Ranges were once a refuge from a changing climate.
Areas like the Flinders Ranges have provided refuge for flora and fauna when the climate has changed. But rapid temperature increases and human intervention may stop them doing so again.
Do we really need one each?
Think you couldn't possibly do without your car? There are more options than you might think.
It’s time to take the political heat out of electricity grids.

Privatisation and competition were supposed to make electricity cheaper. Instead, Australia's quasi-federal energy system has made it easier to pass the buck when things go wrong.
We can learn a lot from Queenslanders.
The latest heatwave put huge pressure on our electricity grid, as Australians turned on their air conditioners. Smarter design and regulations could solve the problem.
Helicopters hover over Bondi Beach after spotting a shark.

LIfeguards could potentially have a new ally in the fight to reduce shark incidents: drones that can spot when a shark swims nearby, and automatically alert authorities.
High gas prices have left Adelaide’s Pelican Point power station running at less than half its capacity.
South Australia's government was angry about the blackouts enforced by electricity regulators. But with much of the state's gas power offline, the regulators had little choice.
Old weather diaries are becoming important in climate research.

High-quality climate records only go back to the start of the 20th century. But using handwritten letters, journals and tables, researchers have access to data going back to the 18th century.
Climate change is already delivering more extremes of wet and dry to the Pacific region.

New research shows that global warming has already begun to exacerbate extremes of rainfall in the Pacific region – with more to come.
Dingoes are often promoted as a solution to Australia’s species conservation problems.

The notion of using dingoes to protect Australia's wildlife is based on wolves in the US, but research cast doubts on the link.
Solar panels can be both a headache and an opportunity for network companies.

Managing voltage on the electricity network has always been an issue. But solar panels have the potential to make the situation better, not worse as some have feared.
Australia’s universities are great at green innovation, but not so good at going low-carbon themselves.
University research has shown us how urgently we need to reduce greenhouse emissions. Yet only three Australian universities have followed through by committing unequivocally to cutting carbon.
Australia: there’s a lot of it to look after.

Australia is wealthy, but its huge size and relatively small rural economy mean we'll have to dig deep to find the cash needed to safeguard our environment.
Firefighters fight forest fire in Indonesia, triggered in part by El Nino.
We’re due to cop a hiding from the Pacific Ocean, but we don’t know when.
