Three Gorges Dam: Friend or foe of riverine greenhouse gases?
Dams are conventionally regarded as emitters of GHGs in large rivers. A team from Peking University of China, however, has disrupted this perception, based on whole system thinking applied to the Three Gorges Dam (TGD) on the Yangtze River in China......»»
Earth to warm up to 2.9C even with current climate pledges: UN
Countries' greenhouse gas-cutting pledges put Earth on track for warming far beyond key limits, potentially up to a catastrophic 2.9 degrees Celsius this century, the UN said Monday, warning "we are out of road"......»»
Scientists set the stage for quantum chemistry in space on NASA"s cold atom lab
For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, the achievement marks another step toward bringing.....»»
Microbes could help reduce the need for chemical fertilizers
Production of chemical fertilizers accounts for about 1.5% of the world's greenhouse gas emissions. MIT chemists hope to help reduce that carbon footprint by replacing some chemical fertilizer with a more sustainable source—bacteria......»»
Greenhouse gases hit record high in 2022: UN
Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, the United Nations warned Wednesday......»»
Video: Monitoring methane from space
Methane is the second most important greenhouse gas contributor to climate change after carbon dioxide. Curbing methane emissions could deliver immediate and long-lasting benefits for the climate, seeing as the gas only lingers in the atmosphere for.....»»
Q&A: How can cities fight climate change and still stay within legal guardrails?
Many U.S. cities are leading the way in cutting emissions of greenhouse gases, with mandates on more efficient buildings, renewable energy and expansion of mass transit. But often these efforts face hurdles in the form of state and federal laws that.....»»
Adding oxygen to a lake to explore methane emissions
Lakes around the world emit methane to the atmosphere, accounting for up to 19% of total global emissions of this potent greenhouse gas. Most of the methane in lakes comes from microbes in the lake bed that consume dissolved organic matter for susten.....»»
Pushing the limits of gas sensing technology
The world has become increasingly industrialized over the past few centuries, bringing all sorts of technology and conveniences to the masses. However, workers in industrial environments are often at risk of exposure to many dangerous gases, such as.....»»
Study finds bacteria use organic phosphorus and release methane in the process
Off Barbados, researchers from Bremen have investigated how bacteria inadvertently release methane in order to obtain phosphorus—with significant effects on atmospheric greenhouse gases......»»
How lab-made catalysts can help convert difficult greenhouse gases
Natural gas consists of light hydrocarbons such as methane and ethane. Such gases are more potent greenhouse gases than CO2, are constantly released into the atmosphere from natural gas wells, and are more difficult to store than, for example, their.....»»
Corporations fall short on implementing green agendas: report
Corporations are increasingly committed to green agendas, but a new report on Tuesday reveals that only one in 20 of over a thousand publicly listed companies have a detailed strategy for how they will reach their greenhouse gas targets......»»
Harmful gases could be detected on-the-spot with new way to generate powerful lasers
Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method to produce intense and ultra-fast lasers that holds promise for making precise devices that can speed up how quickly trace amounts of pollutan.....»»
I made a normal person wear a smart ring. What happened was fascinating
I made my friend, a 'normal' person and not a tech journalist, wear a smart ring. What happened revealed a lot about how we need to think about wearables......»»
Enhanced laser heterodyne spectroscopy helps atmospheric greenhouse gas measurements
A research team led by Prof. Gao Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the measurement accuracy of atmospheric greenhouse gases, including carbon dioxide, by using an Erbium-doped Fiber.....»»
All Captain Toad locations in Super Mario Bros. Wonder
There are many wondrous things to discover in Super Mario Wonder, including our old friend Captain Toad. Here are all the places you can find the explorer......»»
Researchers correct overestimation by "hot model" climate projections on warming in China
Changes in mean temperature and temperature extremes at regional scale under a warmer climate have received much attention. A subset of CMIP6 climate models, known as "hot models," have been projecting more significant warming due to greenhouse gases.....»»
Scientists close the cycle on recycling mixed plastics
Little of the mixed consumer plastics thrown away or placed in recycle bins actually ends up being recycled. Nearly 90% is buried in landfills or incinerated at commercial facilities that generate greenhouse gases and airborne toxins. Neither outcome.....»»
Wildfire smoke leaves harmful gases in floors and walls—air purifiers aren"t enough, new study shows
When wildfire smoke turns the air brown and hazy, you might think about heading indoors with the windows closed, running an air purifier or even wearing a mask. These are all good strategies to reduce exposure to the particles in wildfire smoke, but.....»»
Dingoes given "almost-human" status in pre-colonial Australia, archaeological study finds
It's said that a dog is a man's best friend, but the wild dingo is much maligned in Australia. This may not always have been the case though, with new research led by experts at The Australian National University and The University of Western Austral.....»»
New noble-metal-free electrocatalyst decreases the energy required to generate hydrogen gas from water
As a combustible fuel, the burning of hydrogen gas does not contribute to global warming. Today, the majority of hydrogen gas is generated from fossil fuels, however, and this process releases greenhouse gases into the atmosphere. Generating hydrogen.....»»
