This Indigenous Community Records the Climate Change That Is Causing Their Town to Erode Away
In a tiny village north of the Arctic Circle in Canada, the Inuvialuit of Tuktoyaktuk have taken climate science into their own hands. .....»»
A Soggy Mission to Sniff Out a Greenhouse Gas "Bomb" in the High Arctic
A needle-like tower, hung with sensors, "sniffs" the air above the Arctic circle for signs of catastrophic thaw in the sodden ground below......»»
Flooding that closed Alaska"s Dalton Highway also caused widespread ground sinking
The massive 2015 flooding of the Sagavanirktok River in northern Alaska had immediate impacts, including closure of the Dalton Highway for several days, but it also contributed to longer-term ground subsidence in the permafrost-rich region......»»
More methane production: Combining alkaline pretreatment and air mixing for anaerobic digestion
In 2021, the state of Arkansas soared to third place in the United States' broiler production rankings. While this accomplishment brought economic benefits, it also posed a challenge—a surplus of poultry litter (PL) and growing environmental concer.....»»
"Immediate" cuts to methane from fossil fuel needed: IEA
Methane emissions from fossil fuels must be slashed immediately to limit climate warming, and major reductions are possible with existing technologies at low cost, the International Energy Agency said Wednesday......»»
Study reveals relationship between spatiotemporal variations of freezing index and permafrost degradation
The freezing index (FI) is a crucial factor for calculating the temporal and spatial distribution of permafrost and the thickness of the active layer in a permafrost region. Understanding the variation in thermal conditions of the permafrost active l.....»»
How Arctic landscapes and Canadian cityscapes share a similar pattern
The year 2023 has been one of extremes, from heat waves that baked millions across the globe and made the summer the world's hottest on record to the fires that forced tens of thousands to evacuate across Western Canada. From the feel of surprising w.....»»
Salmon are spawning in Arctic rivers, researchers confirm
Researchers have confirmed that salmon are spawning in an Arctic Ocean watershed, suggesting that at least some salmon species could be expanding to new territory as climate change reshapes their habitat......»»
Potential source of ancient methane eruption identified
Seabed eruptions tied to the start of a sudden warming event 55 million years ago. Enlarge / 3D seismic image showing the crater of the Modgunn Vent and others like it. The cratered surface labelled "BVU" is the seabed of 56 mill.....»»
Ancient plant wax reveals how global warming affects methane in Arctic lakes
By studying fossils from ancient aquatic plants, Northwestern University and University of Wyoming (UW) researchers are gaining a better understanding of how methane produced in Arctic lakes might affect—and be affected by—climate change......»»
Biological particles found to play crucial role in Arctic cloud ice formation
An international team of scientists from Sweden, Norway, Japan, and Switzerland, has presented research findings that reveal a crucial role of biological particles, including pollen, spores, and bacteria, in the formation of ice within Arctic clouds......»»
Fossil results indicate polar bears survived last global warming deglaciation in Siberian and Canadian refugia
Polar bears are a familiar sight to many through the media as we see evocative images of singular bears floating on isolated ice rafts as they face the harsh realities of climate change shrinking sea ice in the Arctic. Their range is significantly im.....»»
From seafloor to space: New bacterial proteins shine light on climate and astrobiology
Gigatons of greenhouse gas are trapped under the seafloor, and that's a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice trap methane gas, preventing it from escaping and bubbling up into the atm.....»»
Quantifying national emissions of methane worldwide
Methane (CH4) stands as the second most important greenhouse gas caused by human activities after CO2 and is responsible for 0.6°C global warming since preindustrial times......»»
Team reviews photocatalysis for methane conversion to high-value products
A research team has published a review paper summarizing the recent progress in methane conversion using photocatalysis. Photocatalysis, the process of using light to accelerate a chemical reaction, offers a promising and green technology for methane.....»»
How fast are Arctic glaciers melting? Engineers explored the north with a robot and cameras to find out
Equipped with snow jackets, gloves and luggage containing a host of cameras and sensors, professor Hanumant Singh and a team of Northeastern robotics researchers recently traveled to the Arctic with a noble goal to help address the climate crisis......»»
Extensive methane gas leakage from the deepest seabed of the Baltic Sea discovered
During a research expedition led by Linnaeus University and Stockholm University to the deepest parts of the Baltic Sea in the Landsort Deep researchers recently discovered an area with extensive emissions of the powerful greenhouse gas methane from.....»»
Re-wetting is key for boosting carbon dioxide storage in southern peatlands, finds study
Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands' carbon storage and reduce the amount of climate-warming carbon dioxide (CO2) and methane they release back into the atmosphere during d.....»»
Riddle of varying warm water inflow in the Arctic now solved
In the "weather kitchen," the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time......»»
French drillers may have stumbled upon a mammoth hydrogen deposit
A drill site in Lorraine shows rising levels of hydrogen mixed in with methane. Enlarge / The equipment needed for drilling a borehole of this type. (credit: Joey Ingelhart) On the outskirts of the small town of Folschvi.....»»
