When the rivers run dry

While NSW has suffered floods, rivers around the world are running dry, prompting calls to restore drained wetlands to improve retention during lengthening periods of drought.

Carbon capture can’t solve the climate crisis

Underperforming carbon capture projects considerably outnumber successful projects with both the technology and regulatory framework found wanting, according to a new report by the Institute for Energy Economics and Financial Analysis.

Don’t wake Antarctica’s ‘sleeping giant’

A new study suggests the worst effects of global warming on Earth’s largest ice sheet can be avoided if the world meets the climate targets outlined in the Paris Agreement – but if we fail, then the melting of the ice sheet will have a drastic impact on sea level rise.

It’s a scorcher

Heatwaves might seem an opportune time to talk about climate change action – but research suggests this could prove ineffectual.

The dominoes are falling fast. We face a climate emergency

The massive task of quickly retooling the economy to a low-carbon system will require national mobilisation akin to wartime, but time is running out for humanity to make the necessary changes to avert a climate catastrophe.

Citizen power and climate action

UNSW Sydney’s Gandhi Oration invites speakers to address some of the human rights issues of our time. This year, the UNSW Centre for Ideas asked Jean Hinchliffe and Peter Garrett to talk about what we can do as citizens to create action for climate change.

We should treat climate change like COVID

COVID-19 provoked an urgent, science-led, whole-of-government response from many nations around the world. With climate change already making a global impact, it’s in everyone’s interest for national governments to take the same approach.

Someone else’s problem, cobber

Australians may want politicians to do more to combat climate change, but remain relatively unwilling to change their own habits to reduce carbon emissions.

An electronic eye on climate change

The development of low-cost sensing technology will help the world assess and react to climate change, according to a new report from Cambridge based IDTechEx.

Halving emissions by 2030

Incremental change is not enough if we want to limit temperature rises to 1.5°C, says the IPCC’s Working Group III, which includes UNSW sustainability expert Tommy Wiedmann.

An open letter to Australia’s political leaders

The first duty of government is to protect the people, but on climate-security risks, the Australian Security Leaders Climate Group claim Australia is missing in action.

A bright future for blue carbon

Blue carbon credits could encourage the return of marginal land to its natural state, absorbing carbon from the atmosphere and protecting biological diversity.
