In the earthquake-prone areas of northern New York and Vermont, a curious geological phenomenon is providing seismologists with critical insights into seismic hazards. Five boulders, known as precariously balanced rocks (PBRs), cling to narrow pedestals, remnants of an ancient glacial past. These geological oddities serve as indicators of the maximum shaking intensity an area may

The U.S. Geological Survey (USGS) has unveiled a groundbreaking landslide susceptibility map that highlights a staggering statistic: nearly 44% of the United States is at risk of experiencing landslide activity. This detailed county-by-county analysis serves not only as a warning but as a crucial resource for planners, engineers, and emergency responders. The innovative mapping endeavors
The Permian-Triassic extinction event, which occurred approximately 252 million years ago, represents one of the most significant and devastating extinction events in Earth’s history, claiming around 96% of marine species and 70% of terrestrial vertebrates. While volcanic eruptions in present-day Siberia have long been implicated in this mass extinction, recent research suggests that the chaotic
In recent years, food waste has emerged as a critical environmental concern, contributing significantly to greenhouse gas emissions and placing unsustainable pressures on landfills. In an effort to combat this issue, several U.S. states have passed food waste bans. However, a study conducted by the University of California Rady School of Management raises serious questions
Abandoned mine drainage (AMD) poses a significant environmental challenge, particularly in Pennsylvania, where a legacy of mining has left a mark on local ecosystems and communities. A recent study conducted by researchers at the University of Pittsburgh highlights the efforts to manage and mitigate the impact of AMD, while also underscoring the funding shortfalls that
In recent years, the phenomenon of floodplain development has grown increasingly concerning, highlighting a tension between growth and environmental risk. A comprehensive analysis conducted by scientists at the University of Miami’s Rosenstiel School has uncovered compelling data regarding the extent of this developmental surge across the United States. With over two million acres of floodplain
In recent years, the construction of dams has surged globally, often hailed as a solution to flood mitigation, particularly in the face of escalating climate challenges such as intense storms and rising sea levels. However, a groundbreaking study published in the Journal of Geophysical Research: Oceans challenges the conventional wisdom regarding the efficacy of dams
In a groundbreaking study spearheaded by Dartmouth College in collaboration with over fifty climate scientists from around the globe, researchers have provided unambiguous predictions regarding the effects of carbon emissions on Antarctica’s ice sheets over the next three centuries. Published in the journal Earth’s Future, the study reveals an alarming consensus among 16 distinct ice-sheet
Precipitation is a complex phenomenon that plays a crucial role in the Earth’s ecosystem. It serves both as a lifeline for agriculture and water supply, while also posing risks in the form of floods and natural disasters. This duality underlines the importance of accurately understanding and predicting precipitation types—an endeavor that carries unique challenges in
Wildfires are an ever-present threat that challenge emergency services, especially firefighters tasked with containing these dangerous blazes. When a wildfire jumps containment lines, swift decision-making becomes crucial. Firefighters are trained to follow predetermined escape routes, but the reliance on experience and basic terrain knowledge often leaves them inadequately prepared for the unpredictable nature of wildfires.
The cultivation of coca, the raw material for cocaine, has long been confined to the mountainous terrains of South America. However, emerging research unveils a daunting shift; almost half of northern Central America—including Honduras, Guatemala, and Belize—displays high suitability for coca farming. This revelation, stemming from a study published in the journal *Environmental Research Letters*,
The advent of artificial intelligence has transformed numerous fields, and geology is poised to reap the benefits as well. Researchers at Stanford University have unveiled SandAI, an innovative AI-driven tool designed to unearth intricate histories embedded within quartz sand grains. This groundbreaking technology allows scientists to discern the geological origins of sand with remarkable precision,
Recent research has illuminated a crucial mechanism that affects the flow and freezing dynamics of meltwater in polar ice sheets, a topic with profound implications for global sea level rise. A collaboration between researchers at The University of Texas at Austin, NASA’s Jet Propulsion Laboratory (JPL), and the Geological Survey of Denmark and Greenland (GEUS)
The sequestration of carbon dioxide (CO2) from Earth’s atmosphere into the deep ocean is an intricate process significantly influenced by microbial life, particularly bacteria. At the core of this phenomenon lies the biological carbon pump—a natural mechanism through which carbon-rich organic material, such as lipids, is transported from the ocean’s surface to its depths, effectively
As winter envelops Northern climates, many embrace the season by taking to local frozen lakes for recreational activities like hockey, skating, or ice fishing. The pristine white surface of crusted ice can appear inviting at a glance. However, a study from York University reveals that these seemingly safe environments hide a perilous reality—changing climate conditions
