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......»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»
New methods predict tipping points for alpine permafrost loss
If the bedrock in the Alps no longer remains permanently frozen, rockfalls may occur more frequently. By measuring electrical resistivity in the ground, researchers can now better understand why this happens......»»

New reconstruction shows low Artic sea ice cover in mid-20th century
An international research team presented a new reconstruction of past Arctic sea ice that revealed low levels of sea ice coverage in the 1940s......»»
NASA returns to Arctic to study summer sea ice melt
What happens in the Arctic doesn't stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth's rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost p.....»»
Kepler"s 1607 pioneering sunspot sketches solve solar mysteries 400 years later
Using modern techniques, researchers have re-examined Johannes Kepler's half-forgotten sunspot drawings and revealed previously-hidden information about the solar cycles before the grand solar minimum......»»
Tunisia"s sandy beaches eaten away by coastal erosion
In Tunisia's seaside town of Hammamet, bulldozers diligently shovel sand from a nearby desert onto a popular beach in an attempt to stop it from disappearing due to erosion......»»
AMD may finally have an answer to Nvidia’s dominance
Although AMD can rival most of Nvidia's graphics cards in pure performance, it always lagged behind in ray tracing. Are things about to improve?.....»»
Mathematicians team up with geophysicists to improve models that predict changes in sea ice
Dartmouth researchers are using computational mathematics and machine learning to develop models that better predict sea ice thickness in regions of the Arctic......»»
Minerals play newly discovered role in Earth"s phosphorus cycle
Northwestern University-led researchers have discovered a new way that nature cycles phosphorus, a finding that uncovers a missing piece of Earth's puzzling phosphorus cycle......»»
Sea ice"s cooling power is waning faster than its area of extent, new study finds
As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research led by University of Michigan scientists......»»
Brazilian researchers discover dinosaur fossil after heavy rains in Rio Grande do Sul
A team of Brazilian scientists has discovered a fossilized skeleton of what they believe is one of the world's oldest dinosaurs after heavy rains in the southern state of Rio Grande do Sul accelerated the natural process of erosion......»»
Tracing millions of years of geologic stress in the Andean Plateau
The Andean Plateau in South America rises, on average, more than 4,000 meters above sea level, formed by orogenic uplift that began more than 20 million years ago. Orogeny occurs at convergent plate margins as compressed plates crumple upward, result.....»»
Apple Intelligence to drive upgrade cycles for iPhone and iPad

Melting ice no guarantee of smooth sailing in fabled Arctic crossing: Study
Melting sea ice in the fast-warming Arctic Ocean is not making it easier for sailors to navigate a legendary shortcut between Europe and Asia despite popular belief, scientists said Thursday......»»
Accepting uncertainty in sustainable fisheries is essential in a rapidly changing Arctic, says researcher
Climate change is making it almost impossible to decide how much, where and what to sustainably fish as the fate of future fisheries is becoming increasingly uncertain. This is leading to a slow process or inaction in adapting fisheries and their man.....»»
Investigating variation in the permafrost active layer over the Tibetan Plateau from 1980 to 2020
The Tibetan Plateau hosts the world's largest permafrost region in the middle and low latitudes. Compared to the high-latitude Arctic permafrost, the permafrost here is thinner, warmer, and more sensitive to global warming. The active layer is a cruc.....»»
Canadian wildfire smoke dispersal worsened by coincident cyclones, study suggests
Wildfires are unplanned and unpredictable threats to Earth; while we may intuitively relate them to extreme heat at lower latitudes, they are known to occur in Arctic regions, such as those recently ravaging Russia......»»
The detection of a massive harmful algal bloom in the Arctic prompts real-time advisories to western Alaskan communities
In the summer of 2022, a research cruise detected a massive harmful algal bloom (HAB) in the Bering Strait region of western Alaska. This expedition provided a dramatic example of science utilizing new technology to track a neurotoxic HAB, and effect.....»»
