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......»»
Electricity-driven catalyst offers climate-neutral methane production
Researchers at the University of Bonn and University of Montreal have developed a new type of catalyst and used it in their study to produce methane out of carbon dioxide and water in a highly efficient way using electricity. Methane can be used, for.....»»
Decades-long research reveals new understanding of how climate change may impact caches of Arctic soil carbon
Utilizing one of the longest-running ecosystem experiments in the Arctic, a Colorado State University-led team of researchers has developed a better understanding of the interplay among plants, microbes and soil nutrients—findings that offer new in.....»»
Methane emissions from dairy farms higher than thought—but conversion to biogas could reduce emissions
New research has found methane emissions from slurry stores on dairy farms may be up to five times greater than official statistics suggest—and highlights the huge potential for turning them into a renewable energy source......»»
Arctic plant study suggests the rate of climate change threatens to exceed the adaptive capacity of species
A research group at the Finnish Museum of Natural History is investigating the adaptive potential of plant species amid a warming climate. Their recent study investigates the Siberian primrose, a plant species that occurs on the coasts of the Bothnia.....»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

Study tracks traveling population wave in Canada lynx
A new study by researchers at the University of Alaska Fairbanks's Institute of Arctic Biology provides compelling evidence that Canada lynx populations in Interior Alaska experience a "traveling population wave" affecting their reproduction, movemen.....»»
Retracing walrus ivory trade of Viking Age reveals early interactions between Europeans and Indigenous North Americans
By examining ancient walrus DNA, an international research team led by Lund University in Sweden have retraced the walrus ivory trade routes of the Viking Age. They found that Norse Vikings and Arctic Indigenous peoples were probably meeting and trad.....»»
Acorn TV launches new crime drama with True Blood star Stephen Moyer
Acorn TV’s new crime drama series Art Detectives, starring True Blood star Stephen Moyer, focuses on crimes committed in the art world......»»
Saturday Citations: Octopuses as shift supervisors for fish; universe confounds standard model; extremely old cheese
This week, biologists tracked down a mysterious group of orcas near Chile; Hubble spotted a black hole jet that causes stars along its trajectory to erupt; and researchers explained mysterious craters that began appearing in Siberian permafrost in th.....»»
Study offers new explanation for Siberia"s permafrost craters
Mysterious craters that first appeared in the Siberian permafrost a decade ago were caused by climate change-driven pressure changes that explosively released methane frozen underground, a new study reports. The research offers a fresh take on the or.....»»
Ice cores show pollution"s impact on Arctic atmosphere
A Dartmouth-led study on ice cores from Alaska and Greenland found that air pollution from the burning of fossil fuels reaches the remote Arctic in amounts large enough to alter its fundamental atmospheric chemistry. The findings illustrate the long.....»»
Arctic sea ice near historic low; Antarctic ice continues decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC). The decline.....»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble.
Searching for polar bears where the Churchill River dumps into Canada's massive Hudson Bay, biologist Geoff York scans a region that's on a low fat, low ice diet because of climate change......»»
Methane is pitched as a climate villain—could changing how we think about it make it a savior?
Surging methane emissions put our ability to meet Paris agreement climate targets in jeopardy. But a timely new book presents the scientific, policy and technological challenges and solutions for achieving rapid climate gains by addressing this once.....»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
India coal expansion risks massive methane growth: Report
India's plans to expand coal mining could double emissions of the potent greenhouse gas methane from its domestic coal sector by 2029, threatening its climate goals, a report warned Thursday......»»
The Arctic Seed Vault Shows the Flawed Logic of Climate Adaptation
The difficulties of the Svalbard seed repository illustrate why we need to prevent climate disaster rather than plan for it.....»»
