Down in the slumps: Tracing erosion cycles in arctic permafrost
In the Arctic, landslide-like features known as mega retrogressive thaw slumps are threatening infrastructure, altering regional biogeochemistry, and emitting carbon......»»
Arctic dust found to be a major source of particles that form ice crystals in Arctic low-level clouds
Researchers from Nagoya University and the National Institute of Polar Research in Japan have found that dust from land without snow cover in the Arctic is a major source of particles that form ice crystals in low-level clouds of the Arctic (at altit.....»»
Research shows shrinking Arctic glaciers are unearthing a new source of methane
As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research published in Nature Geoscience......»»
Diving into history: Newspapers offer historical perspectives on Brazil"s marine biodiversity
Humans have depended on marine ecosystems as a source of food and livelihood for thousands of years along the Brazilian coast. Over the past few decades, increased fishing demands, cycles of profit-driven subsidy programs, and weak governance models.....»»
Tracking ships" icy paths amidst climate change
There has been much buzz about the warming planet's melting Arctic region opening shipping routes and lengthening travel seasons in ocean passageways that ice once blocked. Expanded fishing, trade and tourism is envisioned. The operative word here is.....»»
Fish mercury found to peak in winter and near spawning, then reduce after growing season
The pronounced seasonal changes of warm open-water and cold ice-covered seasons dominate natural cycles in Finnish lakes......»»

The power of Indigenous voices and data supporting the green transition
A new policy paper titled "Data-driven Subnational Decision-making in the Arctic: The power of Indigenous voices and data supporting the green transition" will change the way we look at green transition. The work is published by the team at the Unive.....»»
Animation shows what the world would look like if you could see carbon dioxide emissions
It's a strange, eerie-looking place. Carbon dioxide gas appears… and disappears in cycles and bursts throughout the year. It's how our planet would look if we could detect carbon dioxide (CO2) with our eyes. Scientists at NASA's Global Modeling and.....»»
The Atlantification of the Arctic Ocean Is Underway
The discovery of environmental DNA from fish species that have strayed far from their normal range is an ominous reminder of warming, changing seas......»»
As Arctic warms, caribou and muskoxen slow biodiversity loss
Rapidly warming conditions in the Arctic and the loss of sea ice caused by climate change are driving a steep decline in biodiversity, including among plants, fungi and lichen......»»
Coastal erosion could be reduced by dune restoration projects
Although sand dunes often conjure images of great deserts, they also occur along coastlines worldwide and can be an important buffer for communities threatened by sea level rise, storms and coastal erosion......»»
New study examines variability of water, carbon in Missouri agriculture ecosystems and future impact on crops
One of the main reasons plants use water is to allow them to absorb carbon dioxide from the atmosphere. This means that in plants, the water and carbon cycles are tightly linked. In a new study, researchers from the University of Missouri and the Uni.....»»
Space telescope tracing dark energy to be launched July 1
The Euclid space telescope has a target launch date of July 1, 2023 (18:11 Finnish time at the earliest) with a backup launch date of July 2, 2023......»»
Disappearing Himalayan snow and ice will impact food production in one of the world"s major rice bowls, says report
A major new assessment report from an eight-nation body, the International Center for Integrated Mountain Development (ICIMOD), to which WUR contributed, reveals the changes to the glaciers, snow and permafrost of the Hindu Kush Himalayan region driv.....»»
Plant life found to determine soil bacteria diversity in the Arctic tundra
Living and nonliving factors that influence the types of vegetation that grow at different elevations in the Arctic tundra also regulate the types of bacteria that grow in the soil. The distribution of generalist bacteria, which can adapt to a broade.....»»
Study suggests warfare was responsible for the boom-bust cycles of Neolithic societies
A new study out of the Complexity Science Hub concludes that social disintegration and violent conflict played a crucial role in shaping the population dynamics of early farming societies in Neolithic Europe.....»»
New study maps impact of interprovincial trade on pollution-related mortality in China
In a new study published in the journal Environmental Science and Ecotechnology, researchers from Beijing Normal University bring together five state-of-the-art models from the fields of physics, economics, and epidemiology, tracing the intricate web.....»»
Composite embankment with L-shaped, two-phase, closed thermosyphons influences permafrost deformation: Study
Climate change and engineering disturbance cause degradation of permafrost, which affects infrastructure stability and transportation safety. Two-phase closed thermosyphons (TPCTs) are widely used to tackle external disturbances by cooling the permaf.....»»
Newly planted vegetation accelerates dune erosion during extreme storms, research shows
Newly planted vegetation on coastal sand dunes can accelerate erosion from extreme waves, a study involving researchers from the Oregon State University College of Engineering suggests......»»
How Arctic ice melt raises the risk of far-away wildfires
As millions of people in New York and other major North American cities choke on acrid smoke, they could point their accusatory fingers farther North than the wildfires ravaging Quebec—all the way to the global Arctic......»»
