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......»»
NASA mission gets its first snapshot of polar heat emissions
NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experim.....»»
Hillside erosion worsening in California due to wildfires and intense rain
Over the last three decades, California has seen increasing erosion after major wildfires—a phenomenon that not only endangers water resources and ecosystems, but is also likely to worsen with climate change, according to researchers......»»
Promising antibiotic candidates discovered in microbes deep in the Arctic Sea
Antibiotics are the linchpin of modern medicine: without them, anyone with open wounds or needing to undergo surgery would be at constant risk of dangerous infections. Yet we continue to face a global antibiotics crisis, as more and more resistant st.....»»
iPhone 15 Pro grows US sales as Apple"s market share slumps
Apple's iPhone sales in the United States were down in July despite overall market growth, but the iPhone 15 Pro was a bright spot for the company's shipments.Cameras on an iPhone 15 ProThe iPhone is the most popular smartphone brand in the United St.....»»
Study reveals crucial role of mixing Atlantic and Arctic waters in global ocean circulation
A new study sheds light on the vital role that the mixing of Atlantic and Arctic waters plays in sustaining the Atlantic Meridional Overturning Circulation (AMOC), which is crucial for regulating Earth's climate......»»
Arctic heat waves linked to sea ice loss, new study reveals
Amid global warming, heat waves are striking even the Arctic, a region once considered immune to such extreme weather events. Recent research reveals that these heat waves, particularly in the Barents-Kara Sea (BKS) during the boreal autumn, are not.....»»
Is Betelgeuse actually a binary star?
Betelgeuse has been a favorite among amateur astronomers for many years. However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion. It has a few cycles of variability. One of them occurs.....»»
Moths may use disco gene to regulate day/night cycles
How does one species become two? If you're a biologist, that's a loaded question. The consensus is that, in most cases, the process of speciation occurs when individuals from a single population become geographically isolated. If they remain separate.....»»
Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
From antiquity to adaptation: Tracing the genetic journey of east Asian chestnut varieties
Uncovering the genetic saga of Castanea trees, a study maps their evolutionary journey and local climate adaptations. This research reveals the genetic markers and molecular mechanisms that have allowed these nut fruit trees to adapt and flourish acr.....»»
How human urine can disrupt soil health and water quality
Festival season is in full flow, and like any self-respecting plant-soil biogeochemist attending a local music festival, I'm curious about how these outdoor events might modify important nutrient cycles......»»
Fighting coastal erosion with electricity
New research from Northwestern University has systematically proven that a mild zap of electricity can strengthen a marine coastline for generations—greatly reducing the threat of erosion in the face of climate change and rising sea levels......»»
Mapping Martian meteorites: Tracing origins on the red planet
Researchers have identified the specific locations from which most of the approximately 200 Martian meteorites originate. They've traced the meteorites to five impact craters within two volcanic regions on the red planet called Tharsis and Elysium. T.....»»
"Mercury bomb" threatens millions as Arctic temperatures rise, study warns
The Yukon River flows west across Alaska toward the Bering Sea, eroding Arctic permafrost along its banks and transporting sediment downstream. Within that sediment lurks a toxic stowaway: mercury......»»
Video: Arctic Weather Satellite advancing weather forecasting in a changing climate
The effects of the climate crisis are felt more acutely in the Arctic than anywhere else on the planet. The weather in the Arctic is not only severe, but it changes extremely quickly. More frequent data are urgently needed to improve weather forecast.....»»
Arctic Ocean may absorb less CO₂ than projected due to coastal erosion
As Earth warms, the Arctic Ocean's ability to absorb carbon dioxide from the atmosphere is waning due to melting permafrost and worsening coastal erosion, according to new research......»»
Image: Upper Lake Powell area in Utah
Erosion, tectonic uplift, and a human-built dam have all helped shape the Upper Lake Powell area in Utah......»»
Hazardous Melting Ice Could Sink Arctic Shipping
Warmer temperatures were supposed to make Arctic shipping easier. But thick floating ice created by local melting is a bigger risk than people realized.....»»
Climate change may lead to shifts in vital Pacific Arctic fisheries
Marine fisheries are an essential source of protein for a large part of the world's population, as well as supporting around 390 million livelihoods and an industry worth approximately US$ 141 billion, according to the UN FAO. Yet, climate change pre.....»»
Atmospheric rivers shape long-term changes in Arctic moisture variability
Recent decades have seen rapid warming in the Arctic, known as Arctic amplification, which has impacted the Arctic's cryosphere and ecosystems and influenced global weather and climate through changes in atmospheric circulation......»»
