Nitrous oxide emissions from Corn Belt soils spike when soils freeze and thaw

Credit: Unsplash/CC0 Public Domain Nitrous oxide may be much less abundant in the atmosphere than carbon dioxide, but as a greenhouse gas, it’s a doozy. With a potency 300 times greater than CO2nitrous oxide’s warming potential, especially via agriculture, demands attention. University of Illinois and University of Minnesota researchers are answering the call. In a … Read more

Australia may be heading for emissions trading between big polluters

The current safeguard mechanism has not worked as intended, with emissions still high. Credit: Pexels, CC BY Could Australia soon have a form of emissions trading? Yes, if Labor’s much-anticipated paper on fixing Australia’s mediacre emissions-reduction framework, released today, is any guide. At present, Australia relies on the controversial safeguard mechanism to encourage big emitters … Read more

Worrying finding in California’s climate initiative reveals problem with using forests to offset CO2 emissions

Credit: Pixabay/CC0 Public Domain Researchers have found that California’s forest carbon buffer pool, designed to ensure the durability of the state’s multi-billion-dollar carbon offset program, is severely undercapitalized. The results show that, within the offset program’s first 10 years, estimated carbon losses from wildfires have depleted at least 95% of the contributions set aside to … Read more

Why we can’t rely on regrowing coastal habitats to offset carbon emissions

Credit: Akuditaputri/Shutterstock Removing several hundred billion tons of carbon from the atmosphere is now considered necessary to avert the worst effects of climate change. Using nature to help achieve that goal, by allowing habitats to regenerate, would seem to offer a win-win solution for the environment and the climate. The sediments beneath mangrove forests, saltmarshes … Read more

California emissions, carbon neutrality plan draws criticism

Cement carbon dioxide emissions quietly double in 20 years

Sheep graze on a grass land near a cement plant on the outskirts of Beijing, China, Oct. 17, 2015. New global data released in May 2022, shows that emissions of heat-trapping gases coming from making cement have doubled in the last 20 years. It’s all being driven by China, which is responsible for more than … Read more

Fifth of global food-related emissions due to transport, research finds

Food transport in the context of overall emissions. Credit: University of Sydney In 2007, ‘locavore’—a person who only eats food grown or produced within a 100-mile (161km) radius—was the Oxford Word of the Year. Now, 15 years later, University of Sydney researchers urge it to trend once more. They have found that 19 percent of … Read more

Can farms produce to the max and still reduce greenhouse gas emissions?

Credit: Unsplash/CC0 Public Domain Decarbonizing agriculture is critical for the US to reach net zero emissions by 2050. A new data-driven approach looks at practices that are good for the earth and profitable for farmers. The world relies on American farmers to do much more than set its tables. In addition to producing food for … Read more

Study finds relationships among herbicide-resistant weeds, tillage practices and agricultural greenhouse gas emissions

New study could help reduce agricultural greenhouse gas emissions

Credit: CC0 Public Domain A team of researchers led by the University of Minnesota has significantly improved the performance of numerical predictions for agricultural nitrous oxide emissions. The first-of-its-kind knowledge-guided machine learning model is 1,000 times faster than current systems and could significantly reduce gas emissions from agriculture. The research was recently published in Geoscientific … Read more
