Evaluating changes in dissolved inorganic carbon in the Greenland Sea
To know whether we are complying with emission treaties, all CO2 must be traceable. Incomplete bookkeeping recently sent scientists on a search in the Greenland Sea. Their research is published in the Journal of Geophysical Research: Oceans......»»
Historic fires trapped in Antarctic ice yield key information for climate models
Researchers from the University of Cambridge and the British Antarctic Survey tracked fire activity over the past 150 years by measuring carbon monoxide trapped in Antarctic ice. This gas is released, along with smoke and particulates, by wildfires,.....»»
Landslide triggers megatsunami in narrow fjord
It was a monster wave that hit a fjord on Greenland's east coast on 16 September 2023. In certain places, the traces of the flooding reached 200 meters high. Researchers led by Angela Carrillo Ponce from the German Research Centre for Geosciences (GF.....»»
The earliest traces of life on Earth—researchers explore carbon in 3.9-billion-year-old Canadian rocks
The isotopic composition of carbon in iron formations from the Saglek-Hebron Complex in Nunatsiavut (northern Labrador) has been seen as evidence of the earliest traces of life on Earth. But a new study by the University of Ottawa, Carleton Universit.....»»
Sea of opportunity: Protecting mangroves, seagrass could boost Indonesia"s new climate targets
Indonesia has signaled it could include blue carbon ecosystems—carbon-rich coastal and marine areas, like mangroves and seagrass—in its new climate targets. This shift follows years of relying heavily on the forestry and land sectors as well as t.....»»
High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers
Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. How.....»»
Scientists use carbon isotopes to track "forever chemicals"
Organofluorine compounds—sometimes called "forever chemicals"—are increasingly turning up in our drinking water, oceans and even human blood, posing a potential threat to the environment and human health......»»
Green belts need modernizing—a more "multifunctional" approach can benefit people and planet
Green belts are more than just spaces; for many people, they're places providing a brief escape from the city. Land designated as green belt—and protected from building—can also store carbon and hold water at times of flooding and drought......»»
Modern aircraft emit less carbon than older aircraft, but their contrails may do more environmental harm
Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found......»»
How efficiently different US forests will remove atmospheric carbon in the future
Forests absorb carbon by capturing carbon dioxide from the atmosphere, making forest carbon stocks an important resource against climate change. In research published in Ecology and Evolution, investigators examined existing tree regeneration pattern.....»»
Researchers propose "carbon removal budget" to tackle climate change
New research from the University of Oxford, published in the journal Carbon Management, makes the case for a novel Carbon Removal Budget to help tackle climate change. It would sit alongside the Carbon Budget that governs how much CO2 can safely be e.....»»
Forests destroyed by wildfires emit carbon long after the flames die—new study
Even in Earth's high northern-latitude forest, climate change is predicted to make wildfires more frequent and severe......»»
Ancient poppy seeds and willow wood offer clues to the Greenland ice sheet"s last meltdown
As we focused our microscope on the soil sample for the first time, bits of organic material came into view: a tiny poppy seed, the compound eye of an insect, broken willow twigs and spikemoss spores. Dark-colored spheres produced by soil fungi domin.....»»
Molecules boost from metallic carbon nanotubes
A Lawrence Livermore National Laboratory (LLNL) team has found that pure metallic carbon nanotubes are best at transporting molecules......»»
Greenland fossil discovery stuns scientists and confirms that center of ice sheet melted in recent past
The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was th.....»»
NASA Is ‘Evaluating All Options’ to Get the Boeing Starliner Crew Home
Eight weeks after the Starliner spacecraft launched, NASA is still looking for possible answers to its technical issues—including the possibility of SpaceX lending a hand......»»
Study yields new insights into the link between global warming and rising sea levels
A McGill-led study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the curre.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
NASA says it is “evaluating all options” for the safe return of Starliner crew
SpaceX is actively working on a plan to fly Starliner's crew home. Enlarge / Boeing's Starliner spacecraft is seen docked at the International Space Station on June 13. (credit: NASA) It has now been eight weeks since Bo.....»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»
