How can we use nutritional strategies to mitigate methane emissions from ruminants?
Methane concentrations have increased rapidly and have doubled in the atmosphere compared to preindustrial levels. Within the agricultural sector, animal production contributes to 14.5% of global anthropogenic greenhouse gas (GHG) emissions and produ.....»»
Near-surface permafrost could be nearly gone by 2100, scientists conclude
Most of Earth's near-surface permafrost could be gone by 2100, an international team of scientists has concluded after comparing current climate trends to the planet's climate 3 million years ago......»»
Signs of life? Why astronomers are excited about CO2 and methane in the atmosphere of an alien world
Are we alone? This question is nearly as old as humanity itself. Today, this question in astronomy focuses on finding life beyond our planet. Are we, as a species, and as a planet, alone? Or is there life somewhere else?.....»»
NASA"s new greenhouse gas detector moves closer to launch
A state-of-the-art imaging spectrometer, which will measure the greenhouse gases methane and carbon dioxide from space, moved closer to launch this month after being delivered to a clean room at Planet Labs PBC (Planet) in San Francisco......»»
Reducing the carbon footprint of methane by converting it into methanol with a new enzyme
A team led by Professor Osami Shoji at Nagoya University in Japan has developed a technology to convert methane, the principal component of natural gas, into methanol at room temperature in water. They used an enzyme that can be easily mass-produced,.....»»
Researchers reveal dominant source of atmospheric mercury in the Arctic
A research team led by Prof. Xie Zhouqing and Prof. Le Fange from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) revealed that the Marginal Ice Zone (MIZ) is a dominant source of atmospheric gaseous.....»»
Team develops new gold nanocluster-rich titanium dioxide photocatalyst for the oxidative coupling of methane
The hydrocarbon methane is highly abundant on Earth, yet its release is now known to contribute to surges in temperature and climate change. In recent years, researchers have been trying to devise reliable methods to directly convert methane into oth.....»»
Arctic research grows and strengthens international cooperation: Report
A new report by UArctic highlights the growing diversity and number of research activities across the Arctic. UArctic is a collaboration between academic institutions and other organizations with an interest in northern regions. The report demonstrat.....»»
Making Arctic field geology accessible by digitizing outcrops
The Svalbox Digital Model Database (DMDb) just made its formal debut into the scientific community in a new article published in the journal Geosphere......»»
Even NASA knows we"re all obsessed with Starfield
NASA wants to know why the millions of us obsessed with Starfield haven't applied to "be a NASA intern" yet......»»
Beaver activity in the Arctic linked to increased emission of methane greenhouse gas
The climate-driven advance of beavers into the Arctic tundra is likely causing the release of more methane—a greenhouse gas—into the atmosphere......»»
Methane emissions in LA are decreasing more slowly than previously estimated
Methane is a powerful greenhouse gas, 80 times more potent at warming the atmosphere than carbon dioxide. In 2014, a California law required statewide methane emissions to be cut by 40% by 2030 from 2013 levels. Currently, the local natural gas utili.....»»
If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
Study quantifies link between greenhouse gases, polar bear survival
Polar bears have long symbolized the dangers posed by climate change, as rising temperatures melt away the Arctic sea ice they depend upon for survival......»»
How analyzing ancient and modern polar bear samples reveals the full scope of global warming
The global climate is changing and the Arctic is warming rapidly. These are objectively true statements that most people have come to accept......»»
Past warm period reveals limited near-surface permafrost extent
An international research team led by Dr. Guo Donglin from the Institute of Atmospheric Physics of the Chinese Academy of Sciences has revealed the extent of near-surface (about 3–4 m depth) permafrost during the mid-Pliocene warm period (about 3.2.....»»
Kim Cattrall"s "And Just Like That" cameo has Twitter obsessed
Ever since news of Kim Cattrall's cameo on And Just Like That... was leaked, fans have been waiting with bated breath for the return of the Sex and the City queen. The pending appearance of Samantha Jones has been made all the more splashy thanks to.....»»
Earth"s "third pole" and its role in global climate
Located at the intersection of South, Central, and East Asia, the massive Tibetan Plateau is often considered to be Earth's "third pole." A land of large glaciers, permafrost, and heavy snow, the plateau feeds a vast network of rivers, including majo.....»»
Coexisting carbon-bearing inclusions found in deep mantle wedge peridotite
A research team led by Prof. Xiao Yilin from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) discovered the first diamond-magnesite-methane coexisting multiphase carbon-bearing inclusions in deep mant.....»»
Mapping methane emissions from rivers around globe reveals surprising sources
Freshwater ecosystems account for half of global emissions of methane, a potent greenhouse gas that contributes to global warming. Rivers and streams, especially, are thought to emit a substantial amount of that methane, but the rates and patterns of.....»»
