Do volcanoes add more carbon than they take away?
In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a small net amount of carbon each year. Over geological timescales, that could have a significant.....»»
A new estimate of US soil organic carbon to improve Earth system models
Soil contains about twice as much carbon as the atmosphere and plants combined. It is a major carbon sink, capable of absorbing more carbon dioxide from the atmosphere than it releases. Management of soil carbon is key in efforts to mitigate climate.....»»
How AI and deeper roots can help soil store more carbon
In 2020, global agricultural emissions were 16 billion tons of carbon dioxide equivalent (an increase of 9% since the year 2000) and globally, the 2020 farm gate emission represented nearly half of total agricultural emissions, according to the Food.....»»
Sediment discovery unlocks Australia"s hidden net-zero resource potential
A new method of measuring sediment thickness across Australia's interior offers a cost-effective and straightforward solution for estimating seismic hazard and resource potential while reducing carbon footprint, according to the largest study of its.....»»
Viewpoint: Fossil fuel subsidies cost Canadians a lot more money than the carbon tax
The federal carbon tax increase is now in effect, and will raise gas prices by three cents per liter in most Canadian provinces......»»
Can savanna emerge in the cold high latitudes and altitudes due to ongoing rapid warming?
Recent studies have shown that rising atmospheric CO2 concentrations and consequential warming may compromise the community structure and functioning of the cold tundra ecosystems. However, in addition to carbon uptake, natural vegetation—particula.....»»
Engineers "symphonize" cleaner ammonia production
Among the many chemicals we use every day, ammonia is one of the worst for the atmosphere. The nitrogen-based chemical used in fertilizer, dyes, explosives and many other products ranks second only to cement in terms of carbon emissions, due to the h.....»»
New satellite dataset sheds light on Earth"s plant growth
Gross Primary Production (GPP), the process through which plants convert carbon dioxide and sunlight into glucose and oxygen, is the Earth's largest carbon flux. Accurate quantification of GPP is crucial for understanding carbon budgets and their imp.....»»
Researchers show depth-dependent responses of soil organic carbon under nitrogen deposition
In a study published in Global Change Biology, scientists from the Institute of Earth Environment and the South China Botanical Garden of the Chinese Academy of Sciences have shed light on understanding the effects of nitrogen addition on soil organi.....»»
New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process
In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The technologies for reducing ou.....»»
New carbon nanotube transistor enhances sensitivity and resolution of molecule glasses
Researchers have developed a carbon nanotube (CNT) transistor for molecule glasses that facilitates detailed examination of molecular interactions. This innovative technology is poised to open a fresh research direction in nanotechnology and molecula.....»»
A high-efficiency photocatalyst for converting carbon dioxide into environmentally friendly energy using sunlight
DGIST Professor In Su-il's research team has developed a high-efficiency photocatalyst that utilizes sunlight to convert carbon dioxide (CO2), the primary cause of global warming, into methane (CH4) fuel. The research team expects that this environme.....»»
Study underscores uncertain costs of iron fertilization
As society grapples with the intensifying consequences of climate change, decision-makers are increasingly looking to carbon dioxide removal as a necessary complement to emission reductions. One of the strategies that has received the most attention.....»»
A catalyst for converting carbon dioxide, the main cause of global warming, into ethylene using vitamin C
A joint research team has developed a new electrochemical catalyst that promotes the conversion from carbon dioxide (CO2) to ethylene (C2H4)......»»
How carbon removal fits into the architecture of EU climate policy
The EU has recently made far-reaching decisions on rapid greenhouse gas emissions reduction. For example, from 2027, like in the energy and industry sectors, it will also cap emissions in the problem sectors of heating and transport through emissions.....»»
Carbon credits would enable restoration of UK saltmarshes, say experts
While the marshes may have meant danger for Pip in "Great Expectations," these wetland habitats are important wildlife havens and mitigate climate change......»»
Blueprint for mandating indoor air quality for public buildings in form of standards
In research published in the journal Science experts addressed setting standards for three key indoor pollutants—carbon dioxide (CO2), carbon monoxide (CO), PM2.5, which are particles so small they can lodge deep in the lungs and enter the bloodstr.....»»
Study finds landfill point source emissions have an outsized impact and present opportunity to tackle US waste methane
A new study, led by Carbon Mapper scientists alongside researchers from NASA Jet Propulsion Laboratory, Arizona State University, University of Arizona, Scientific Aviation, and the U.S. Environmental Protection Agency, provides the largest comprehen.....»»
Forest regeneration projects failing to offset carbon emissions
Forest regeneration projects that have received tens of millions of carbon credits and dominate Australia's carbon offset scheme have had negligible impact on woody vegetation cover and carbon sequestration, new research from The Australian National.....»»
Hyundai plans $51 billion investment in EVs, software-defined vehicles over 3 years
Hyundai is adding 80,000 new employees, including 44,000 new hires in electrification, SDVs and carbon neutrality......»»
Advancing towards sustainability: Turning carbon dioxide and water into acetylene
Reaching sustainability is one of humanity's most pressing challenges today—and also one of the hardest. To minimize our impact on the environment and start reverting the damage humanity has already caused, striving to achieve carbon neutrality in.....»»
