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......»»
Video: What does a warming Arctic mean for the future?
The Arctic is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects. This rapid warming has profound implications for global climate patterns, human populations and w.....»»
Wars in Ukraine and Gaza could soon affect our approach to the North Pole, researcher warns
The Houthis are attacking ships in the Red Sea. Rerouting via South Africa is expensive, whereas the Arctic route only takes a week. Once a no-go zone, this route might be a more realistic option. Mind the nuclear submarines, though….....»»
Study shows methane emissions from wetlands increase significantly over high latitudes
Wetlands are Earth's largest natural source of methane, a potent greenhouse gas that is about 30 times more powerful than carbon dioxide at warming the atmosphere. A research team from the Department of Energy's Lawrence Berkeley National Laboratory.....»»
Scientists find evidence of geothermal activity within icy dwarf planets
A team co-led by Southwest Research Institute found evidence for hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, located in the Kuiper Belt. Methane detected on their surfaces has the tell-tale signs of warm or ev.....»»
Google, Environmental Defense Fund will track methane emissions from space
Satellite data + Google Maps + AI should help figure out where methane is leaking. Enlarge / With color, high resolution. (credit: Google/EDF) When discussing climate change, attention generally focuses on our soaring ca.....»»
Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night
In the dark and cold of the months-long polar night, food resources are limited. Some groups of marine organisms in the polar regions overcome this challenge by going into a metabolic resting state in winter, surviving on reserves accumulated during.....»»
Researchers identify a decline in microbial genetic richness in the western Arctic Ocean
The Arctic region is experiencing climate change at a much faster rate than the rest of the world. Melting ice sheets, runoff from thawing permafrost, and other factors are rapidly changing the composition of the Arctic Ocean's water. And that change.....»»
Cold-resistant bacteria found in the Arctic can degrade crude oil
The Arctic region is being actively developed by humans, but it negatively affects the environment. The fact is that Arctic soils, which contain little organic matter, are susceptible to the toxic effects of hydrocarbons that get there as a result of.....»»
A new map tool for monitoring pan-Arctic trends of permafrost landscape change
Permafrost (from "permanent" and "frost") is ground that continuously remains at or below 0° C for at least two consecutive years. Around 15% of the land surface in the Northern Hemisphere is underlain by permafrost, which often contains and preserv.....»»
New UN weather agency chief says rate of global warming is speeding up
The new chief of the World Meteorological Organization said it looks to her that the rate of human-caused climate change is accelerating and that warming has triggered more Arctic cold outbreaks in North America and Europe, weighing in on two issues.....»»
Biotrickling filter supports efficient hydrogen-methane conversion for biological biogas upgrading
Biological hydrogen-methane conversion refers to the production of methane through the action of microorganisms using hydrogen generated by electrolysis of water with residual power and carbon dioxide present in biogas. This approach promises to over.....»»
Frequent marine heat waves in the Arctic Ocean will be the norm, says new study
Marine heat waves will become a regular occurrence in the Arctic in the near future and are a product of higher anthropogenic greenhouse-gas emissions, according to a study just released by Dr. Armineh Barkhordarian from Universität Hamburg's Cluste.....»»
Alex Honnold on life after Free Solo and new docuseries Arctic Ascent
In a conversation with Digital Trends, famed climber Alex Honnold discusses finding purpose after El Cap and filming his new Disney+ docuseries, Arctic Ascent......»»
Sedimentary records of contaminant inputs in Frobisher Bay provide record of changes in contaminant levels over decades
Although contaminant levels in Arctic environments are often lower than those in temperate locations close to cities and industrial areas, contaminant studies in the Arctic remain important due to the potential for bioaccumulation and biomagnificatio.....»»
Permafrost alone holds back Arctic rivers—and a lot of carbon
New research from Dartmouth College provides the first evidence that the Arctic's frozen soil is the dominant force shaping Earth's northernmost rivers. Permafrost, the thick layer of soil that stays frozen for two or more years at a time, is the rea.....»»
Improving Arctic greenhouse gas sink and source estimates with field measurements, remote sensing
A new study investigates the sinks and sources of key greenhouse gases of carbon dioxide, methane, and nitrous oxide in the Arctic landscape with a spatial resolution of only a few square meters. Vegetation and soil conditions explain the differences.....»»
New study reports that Greenland is a methane sink rather than a source
Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland. The results of the new study contribute important knowledge to climat.....»»
Study predicts best times for Curiosity to sample Mars" methane
Since methane was first detected in Mars' atmosphere 20 years ago, scientists have struggled to uncover its origins and how it is transported around the Red Planet. Measurements from atmospheric samples collected by NASA's Curiosity rover at Gale cra.....»»
Study tracks how wetland tree stem emissions vary by season, location, and hydrological conditions
The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are a.....»»
Coastal chemistry improves methane modeling
Scientists at Oak Ridge National Laboratory are using a new modeling framework in conjunction with data collected from marshes in the Mississippi Delta to improve predictions of climate-warming methane and nitrous oxide emissions from soils in coasta.....»»
