The real dirt on carbon farming

Soil carbon’s role in reducing Australia’s carbon dioxide emissions is critical to the federal government’s plan for the nation to achieve net-zero emissions by 2050. Estimates based on CSIRO data suggest that between 35 million and 90 million tonnes of CO2 equivalent could be stored annually through soil carbon sequestration – drawing carbon from the … Continue reading The real dirt on carbon farming

Talking time is over: business and industry plan for climate action

With the Glasgow climate summit just a few weeks away, a group of Australian business and industry leaders have come together to form the Climate Ready Australia 2030 (CRA2030) alliance with a goal to create a detailed plan on how to quickly transition to a net zero future. “I think all the debate to date … Continue reading Talking time is over: business and industry plan for climate action

A pig problem for climate change

Wild pigs are releasing nearly five million tonnes of trapped soil carbon dioxide annually – about the same as that produced by a million cars – which may contribute to climate change, according to a new study published in Global Change Biology. A team of researchers, led by Christopher O’Bryan of the University of Queensland, … Continue reading A pig problem for climate change

Getting to zero

Dr Alan Finkel trained as a neuroscientist and engineer and forged a successful career as a technology entrepreneur. At the end of 2020 he completed a five-year term as Australia’s chief scientist; he continues to act as a special adviser to the Australian government on low-emissions technologies. These days he’s perhaps best known as a … Continue reading Getting to zero

Less carbon = greater food cost?

A Swiss study has found that using carbon dioxide removal alone to mitigate agricultural emissions is likely to increase food costs. Carbon dioxide removal – or CDR – is often touted as a solution for industries that can’t easily reduce their emissions. What is carbon dioxide removal? Also called negative emissions technology, CDR is a … Continue reading Less carbon = greater food cost?

When glaciers melt, carbon rises

In the face of rising temperatures, water from glaciers may be both a bane and a boon for rivers, as the melting contributes to the carbon cycle. An international team, led by Sarah Fell of the University of Leads, UK, has found that mountain rivers that rely on mountain glacier water have higher rates of … Continue reading When glaciers melt, carbon rises

New view of Tweed Valley’s attraction

Australia’s Tweed Valley region, in northern NSW, boasts world-class surf breaks and sub-tropical rainforest – and according to new research, it is also the perfect natural laboratory to pull carbon out of the atmosphere. To meet the Paris Agreement and prevent the average global temperature from rising more than two degrees Celsius above pre-industrial levels, … Continue reading New view of Tweed Valley’s attraction

Elements of surprise in new star study

Stars churn out carbon much faster than previously thought, according to new measurements by Australian and Norwegian physicists. “It’s a really surprising result, with profound implications across astrophysics,” says Tibor Kibédi, nuclear physicist at the Australian National University (ANU) and one of the lead researchers. The measurement may have a major impact on our understanding … Continue reading Elements of surprise in new star study

A new way to analyse old things

By Chris Turney, Alan Hogg, Paula J Reimer and Tim Heaton Geological and archaeological records offer important insights into what seems to be an increasingly uncertain future. The better we understand what conditions Earth has already experienced, the better we can predict (and potentially prevent) future threats. But to do this effectively, we need an … Continue reading A new way to analyse old things

Tropical soils linked to carbon emissions

Scientists continue to unravel the feedback loops caused by global warming, a major one being the soil’s release of carbon dioxide (CO2). Now, a study published in the journal Nature reports that soils in tropical forests are far more sensitive to global warming than previously thought.  Researchers warmed tropical soil by four degrees Celsius – an increase … Continue reading Tropical soils linked to carbon emissions

New views on the origins of carbon

Every carbon atom in the Universe was created by stars, through the fusion of three helium nuclei, but which types of stars are the primary source is the subject of an ongoing debate among astrophysicists. Some favour low-mass stars that blew off their envelopes in stellar winds and became white dwarfs, while others favour massive … Continue reading New views on the origins of carbon

Scientists report lunar carbon emissions

Japanese scientists have reported observing carbon ions persistently emitting from the lunar surface. Given that the prevailing theory for the Moon’s formation strongly relies on the notion of a volatile-depleted modern Moon, they say, these findings could have far-reaching implications for our understanding of how it actually came to exist.  “Our estimates demonstrate that indigenous … Continue reading Scientists report lunar carbon emissions
