Webb rules out thick carbon dioxide atmosphere for rocky exoplanet
Infrared measurements of TRAPPIST-1 c indicate that it is probably not as Venus-like as once imagined......»»
Nations approve new UN rules on carbon markets at COP29
Governments at the COP29 talks approved Monday new UN standards for international carbon markets in a key step toward allowing countries to trade credits to meet their climate targets......»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
Monitoring Webb"s mirrors for optimal optics
NASA's James Webb Space Telescope is the largest and most powerful telescope ever launched to space. Its mirror is composed of 18 individual segments that have been aligned so accurately, that they effectively work as a single giant (21.6-foot, or 6......»»
White truffles, Italy"s gold, menaced by climate change
Deep in a thick forest in Italy's northwestern Piedmont region, the hunt is on for the white Alba truffle, with excited dogs zigzagging and digging into the wet earth......»»
Private jet carbon emissions soar 46%: Study
The carbon footprint from private jet travel grew 46 percent between 2019 and 2023 and will keep rising unless the ultra-luxury industry is regulated, according to new research published Thursday......»»
China passes energy law to "promote carbon neutrality"
China on Friday passed a new energy law to promote carbon neutrality, state media reported, as Beijing moves ahead with its pledge to decarbonize its economy by 2060......»»
Advances in plate tectonics research provide a new view of deep Earth"s carbon emissions
From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar Müller and colleagues show how this gas released from.....»»
Battling air pollution may contribute to climate change by impacting soil carbon storage
Decades-old policies aimed at improving air quality may also be accelerating global climate change, warns a recent study published in the journal Ecology......»»
Airborne microplastics aid in cloud formation
It turns out microplastics have an effect on the weather and climate. Clouds form when water vapor—an invisible gas in the atmosphere—sticks to tiny floating particles, such.....»»
India"s Hindus bathe in holy river defiled by pollution
Sweeping aside thick toxic scum, thousands of Hindu devotees ignored court warnings Thursday against bathing in the sacred but sewage-filled Yamuna river, a grim display of environmental degradation in India's capital......»»
Calcite: The versatile mineral shaping the future of carbon removal
Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone......»»
Nearly three years since launch, Webb is a hit among astronomers
Demand for observing time on Webb outpaces supply by a factor of nine. From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther.....»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»
Astronomers use JWST and ALMA to explore the structure of a giant spiral galaxy
Using the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers have observed a giant spiral galaxy designated ADF22.A1. Results of the observational campaign, published Oc.....»»
Microbial slime: The ultimate system to understand our planet
Billions of years ago, Earth was home to extreme environments, including intense UV radiation, frequent volcanic eruptions, and very high concentrations of carbon dioxide in the atmosphere. Yet, under these conditions, biofilms formed and within thes.....»»
Direct synthesis method uses recovered carbon dioxide and hydrogen to produce formic acid
With the goal of achieving a carbon-neutral society and eliminating greenhouse gas emissions by 2050, efforts are accelerating to utilize hydrogen as a key energy source. To achieve this goal, the technologies for hydrogen storage, transportation, an.....»»
Volcanic ash as a source of nutrients: How the Hunga Tonga eruption affected ecosystems in the South Pacific
The eruption of Hunga Tonga-Hunga Ha'apai (HTHH) in January 2022 ejected about 2.9 billion tons of volcanic material into the atmosphere and across the South Pacific. In early 2022, a scientific expedition (GEOTRACES GP21) investigated the impact of.....»»
The frozen carbon of the northern permafrost is on the move—we estimated by how much
Among the most rapidly changing parts of our planet are the coldest landscapes near the top of the globe, just south of the Arctic. This region is warming two to four times faster than the global average......»»
Kagome superconductor breaks the rules at record-breaking temperatures
Using muon spin rotation at the Swiss Muon Source SmS, researchers at the Paul Scherrer Institute (PSI) have discovered that a quantum phenomenon known as time-reversal symmetry breaking occurs at the surface of the Kagome superconductor RbV3Sb5 at t.....»»
Soil sampling in Houston"s greater Fifth Ward reveals toxic levels of lead in yards, play areas
Houston, like many American cities, has areas with soil contaminated by non-biodegradable and persistent pollutants such as arsenic, lead, nickel and cadmium, known as heavy metals and metalloids. These are both naturally occurring in the atmosphere.....»»
