The Arctic’s Permafrost-Obsessed Methane Detectives
The Far North is thawing, unleashing clouds of planet-heating gas. Scientists rely on an arsenal of tech to sniff out just how nasty the problem is......»»
From Arctic to Alps, icy exploration expands understanding of global warming
Microalgae in sediments signal what happened in the environment thousands of years ago, illuminating the range of future climate-change impacts......»»
Arctic sea ice loss and fierce storms leave Kivalina fighting to protect the island from climate disasters
As winds and waves from Typhoon Merbok devastated communities along the coast of Western Alaska in 2022, Reppi Swan Sr.'s phone began to ring at Kivalina, a barrier island 80 miles above the Arctic Circle......»»
Microbial necromass carbon causes dramatic carbon loss in permafrost thaw slump of Tibetan Plateau
Permafrost in the Tibetan Plateau contains a large amount of soil organic carbon (SOC). Climate change leads to rapid permafrost degradation and thermal collapse, which can change the microgeomorphology and soil physical and chemical properties......»»
What microbes can tell us about life on Earth and in space
Microbes are just about everywhere, from the soil to the air to Arctic ice to oceans, lakes, and rivers—not to mention all over your body and the phone or computer you're using right now......»»
Study reveals how extreme cold events in south China relate to Arctic autumn sea-ice extent
A joint research team led by Prof. Xiao Cunde from Beijing Normal University, Dr. Du Zhiheng and Dr. Yang Jiao from the Northwest Institute of Eco-Environment and Resources (NIEER) of the Chinese Academy of Sciences (CAS) has revealed how extreme col.....»»
I’m obsessed with the Galaxy S23 Ultra’s camera — and these photos show why
I spent two weeks taking 3,000 photos with the Galaxy S23 Ultra's camera. I'm obsessed with it, and these photos show exactly why......»»
Microplastics have infected critical Arctic ice algae
A critical component of the food web in the Arctic is at risk. According to a new study published in the journal Environmental Science and … The post Microplastics have infected critical Arctic ice algae appeared first on BGR. A crit.....»»
Scientists save ancient Arctic ice in race to preserve climate history
Scientists have succeeded in saving samples of ancient Arctic ice for analysis in a race against time before it melts away due to climate change, they said this week......»»
A Critical Arctic Organism Is Now Infested With Microplastics
The algae Melosira arctica is the foundation of the food chain, and its contamination could have major consequences for ecosystems and the climate......»»
Arctic ice algae heavily contaminated with microplastics, reports new research
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea s.....»»
Cracking the case of mitochondrial repair and replacement in metabolic stress
Scientists often act as detectives, piecing together clues that alone may seem meaningless but together crack the case. Professor Reuben Shaw has spent nearly two decades piecing together such clues to understand the cellular response to metabolic st.....»»
Conventional aerobic methanotrophs have metabolic versatility under anoxia
Methane (CH4) is a potent greenhouse gas with a global warming potential 28 –34 times that of carbon dioxide on a centennial time scale. Microbial CH4 oxidation acts as a biofilter, preventing more than 90% of CH4 from entering the atmosphere......»»
Sea ice algae on which Arctic animals rely under threat from climate change
Sea ice algae is an essential resource for the survival of many species living in the Arctic......»»
Greenhouse gas release from permafrost found to be influenced by mineral binding processes
About a quarter of the organic carbon contained in ice-rich Arctic permafrost is more difficult for microorganisms to utilize. The reason for this is a strong binding of the organic material originating from dead plant remains to mineral soil particl.....»»
Hands-on: This limited edition Untitled Folder Wallet is inspired by Apple’s macOS folder icon
New York-based artist Nik Bentel has been known to bring a level of whimsy to his work that I’ve personally been obsessed with for ages now. As if past work like his Shipping Box Bag didn’t speak to me enough, the artist’s latest piece is look.....»»
Methane from megafires: Novel detection technique raises pollution policy questions
Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires—a source not currently being accounted for by state air quality managers......»»
Why using more fertilizer and feed does not necessarily raise dairy farm profits but increases climate harm
New Zealand is in an unusual position in the developed world when it comes to greenhouse gas emissions. About half of all emissions come from agriculture, and almost a quarter can be attributed to biological emissions (nitrous oxide and methane) from.....»»
World"s biggest cumulative logjam, newly mapped in the Arctic, stores 3.4 million tons of carbon
Throughout the Arctic, fallen trees make their way from forests to the ocean by way of rivers. Those logs can stack up as the river twists and turns, resulting in long-term carbon storage. A new study has mapped the largest known woody deposit, cover.....»»
Exploring catalytic methane removal to mitigate its environmental effect
A new review published in Science China Chemistry has summarized recent progresses in the oxidation of methane via both thermocatalysis and photocatalysis through the lens of environmental remediation. The review was led by Prof. Junwang Tang, Depar.....»»
Arctic"s peak ice cover has shrunk by an area larger than Egypt
Sea ice covered 5.64 million square miles of the Arctic Ocean at the ice's peak extent this year in early March. That's almost 400,000 square miles less than the median coverage level at other March peaks between 1981 and 2010, according to the Natio.....»»
