Saturday Citations: The volcanoes of Mars; Starship launched; "Try our new menu item," say Australian researchers
You never can tell when planetary scientists are going to discover a new giant volcano on Mars, but when it happens, I step out to the porch and raise my Lunar and Planetary Society Core-Mantle Boundary Rift Discovery flag so all the neighbors will k.....»»
Climate: Carbon capture tech is booming, and confusing
Humanity's failure to reduce planet-heating carbon pollution—at record levels in 2023—has thrust once-marginal options for capping or reducing CO2 in the atmosphere to center stage......»»
Satellite data unlocks drought impact on southwest China"s carbon cycle
Over the past four decades, Southwest China has been a major carbon sink, significantly mitigating anthropogenic CO2 emissions. However, recent severe droughts, especially from 2009 to 2013 and in 2022, have drastically reduced its carbon absorption.....»»
Photocatalytic synthesis of arylacetic acid via C=C double bond cleavage with carbon dioxide
Alkenes represent one of the most abundant classes of organic molecules, which are available in bulk quantities from petroleum and renewable resources, with various utilization in agrochemistry, pharmacy, and organic materials. Typically, the transfo.....»»
Researchers offer unique way to monitor carbon emissions in bodies of water
Carbon dioxide (CO2) emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide......»»
Study reveals ancient ice may still exist in distant space objects

Apple refutes criticism of its carbon neutral plans by showcasing its rainforest efforts
Aiming to show that its carbon reduction efforts are not mere "climate-washing," Apple has spotlighted how its Restore Fund is contributing to the restoration of a Brazilian rainforest, and attempts to save over 3,000 types of tree from extinction.Wo.....»»
Carbon-neutral beef? Argentina"s new certification could promote more climate-friendly livestock production
In Argentina, where beef is a symbol of national pride, a government-led partnership has started certifying certain livestock as carbon neutral. It's a big step that shouldn't be underestimated, but getting the certification process right is crucial......»»
Increasing soil organic matter to improve soil health, carbon storage
Soil organic matter (SOM) is crucial to soil health and carbon storage in agriculture. Adding crop residues to the soil increases SOM, but can also accelerate its decomposition, known as the priming effect. The temperature sensitivity (Q10) of SOM de.....»»
Giant sequoias are a rapidly growing feature of the UK landscape
Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study led by UCL researchers with colleagues at the Royal Botanic Garden.....»»
Climate policies to reduce motor vehicle emissions can improve children"s health and save money, finds study
A new study finds that policies to reduce carbon dioxide (CO2) emissions from motor vehicles combined with investments in electric vehicles and public transportation would reduce air pollution and bring large benefits to children's health. They would.....»»
Uber offers new feature for environmentally conscious riders
Uber has rolled out a new app feature for riders interested in keeping track of carbon emission savings when they use one of the company's greener vehicles......»»
Researchers devise new ways to engineer carbon-based semiconductors for electronics of the future
It might look like a roll of chicken wire, but this tiny cylinder of carbon atoms—too small to see with the naked eye—could one day be used for making electronic devices ranging from night vision goggles and motion detectors to more efficient sol.....»»
Canals used to drain peatlands are underappreciated hotspots for carbon emissions, new study finds
A new study led by UC San Diego Scripps Institution of Oceanography postdoctoral scholar Jennifer Bowen finds that canals used to drain soggy peatlands in Southeast Asia are likely hotspots for greenhouse gas emissions......»»
Satellite measurements show that global carbon emissions are still rising
According to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6), human activities have significantly impacted the planet. As global greenhouse gas emissions (mainly carbon dioxide) have continued to increase, so too ha.....»»
