How zoning affects greenhouse gas emissions
Climate change is a global challenge often met on a local level. Local governments shape how their communities are developed through land use controls. Their policy decisions related to housing density, location, and building standards have a profoun.....»»
Molecular "pinball": Superfast collisions predict supercritical fluid properties
Neither gas nor liquid, supercritical fluids exhibit a unique mashup of the properties of both and arise when fluids are pushed to very high temperatures and pressures. Their properties make them ideal for a wide variety of chemical, pharmaceutical a.....»»
Novel MOF combines adsorption and dissolution for energy-efficient oxygen separation from argon
Efficient gas separation is vital in various industries, from medical applications to energy production. However, isolating oxygen from mixtures presents a significant technological challenge. Because many gases, including argon and oxygen, share sim.....»»
San Diego is relaxing its no-gas rule for new city buildings: To environmentalists, it"s "a giant loophole"
Local environmentalists are criticizing San Diego for retreating on a two-year-old policy that requires all new and significantly renovated city buildings to rely entirely on electricity instead of gas......»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Sweden is a nearly cashless society. Here"s how it affects people who are left out
Around the world, cards and apps are the default way to pay—but nowhere is the transition away from cash more obvious than in Sweden. The Bank of Sweden notes that the amount of cash in circulation in the country has halved since 2007......»»
EPA lets California set its own stricter emissions standards until 2035
The regulations will phase out the sale of new internal combustion cars by 2035. Today, the US Environmental Protection Agency granted a pair of waivers to California, allowing th.....»»
Study explores effects of particle emissions from offshore wind farms on blue mussels
After several years of service under harsh weather conditions, the rotor blades of offshore wind parks are subjected to degradation and surface erosion, releasing sizeable quantities of particle emissions into the environment......»»
Young exoplanet"s atmosphere unexpectedly differs from its birthplace
Just as some children physically resemble their parents, many scientists have long thought that developing planets should resemble the swirling disk of gas and dust that births them......»»
How the loss of urban trees affects education outcomes
It's well established that urban tree cover provides numerous environmental and psychological benefits to city dwellers. Urban trees may also bolster education outcomes and their loss could disproportionately affect students from low-income families,.....»»
New rules for cutting emissions at Colorado natural gas facilities will be "tough for everybody"
Colorado air-quality regulators this week will tackle one of the more complicated rules the state has drafted, ordering about 40 natural gas companies to reduce their greenhouse-gas emissions or pay into a system designed to help businesses lower the.....»»
Ammonia production goes green: Biomethane approach offers net-zero emissions
Using biomethane to produce ammonia, a crucial chemical in agriculture, could drastically reduce the climate impact of the process. In a study published in One Earth, researcher Robert Istrate shows it's even possible to make ammonia production net-z.....»»
New climate chemistry model finds "non-negligible" impacts of potential hydrogen fuel leakage
As the world looks for ways to stop climate change, much discussion focuses on using hydrogen instead of fossil fuels, which emit climate-warming greenhouse gases (GHGs) when they're burned. The idea is appealing. Burning hydrogen doesn't emit GHGs t.....»»
On Trump’s chopping block: EVs, charger funding, California’s emissions
Trump's attack on clean vehicles to be bigger than thought, says report. The incoming Trump administration has even more plans to delay electric vehicle adoption than previously t.....»»
What 92 years of data say about ice cover
Warming air temperatures are changing ice cover in seasonally frozen lakes worldwide. The timing of ice formation and melting, called ice phenology, affects lake temperatures, seasonal stratification, and lake ecology, though much about these dynamic.....»»
Rising drought frequency poses new threats to US wildlife, study finds
People around the world are dealing with drought, so it's not shocking that it affects wildlife, too: lack of moisture contributes to habitat loss, affects how animals compete for resources, and leads to dehydration and heat stress. The surprising pa.....»»
Airborne observations identify major source of US landfill methane emissions
A team has found via testing from airplanes that landfill work faces tend to be responsible for the biggest share of methane emissions in U.S. landfills. Their findings are published in the journal Environmental Science and Technology. The researcher.....»»
EV drivers are not going back to gas cars, global survey says
Nearly all current owners of EVs are either satisfied with the experience, and 92% of them plan to buy another EV, according to a global survey. .......»»
Satellites capture dramatic increase in HFC-125, a potent greenhouse gas
HFC-125 is a greenhouse gas becoming a major contributor to global warming, and in the first study to use satellites to measure its concentration in the atmosphere, researchers found it has increased exponentially in the past 20 years......»»
Oxidation in glacial rivers and lakes could help mitigate methane emissions
A new study offers a rare glimmer of hope in the face of climate change, suggesting glacial rivers and lakes may play a crucial role in mitigating the effects of methane—a powerful greenhouse gas that recent studies have shown emerges as glaciers m.....»»
As Christmas catering approaches, experts review food waste policies
Composting and green bins are making their mark on recycling organic waste, but Australian households are still responsible for millions of tons of greenhouse-gas emitting food waste ending up in landfill......»»
