Scientists propose a colossal cliff across ancient North America may have exposed Grand Canyon's oldest rocks nearly a billion years before it was carved by the Colorado River. The study suggests the 'great escarpment' of steep rocky cliffs formed when the supercontinent Rodinia broke apart 800 million years ago.
The 36th annual State of the Climate report reveals record highs in greenhouse gas concentrations, global sea level, and ocean heat content. Greenhouse gas concentrations reached a 53% increase from preindustrial levels, with fossil fuel emissions reaching a record high in 2025.
Researchers provide a framework to assess cumulative heat exposure from marine heatwaves and preceding/post-warming anomalies, revealing underestimation by historic assessments. The study finds that prolonged warm water exposure can create conditions that species may not survive.
Researchers found two distinct growth patterns in river deltas, uniform and composite, which can help engineers estimate land build-up based on channel length. This insight will aid coastal restoration and flood protection efforts by directing limited resources to areas where they can make the most impact.
A new study reveals that subsidence is a major driver of coastal flooding along Java Island, with rates of up to 15 centimeters per year. Groundwater withdrawal and agricultural water use are identified as key culprits, highlighting the need for active monitoring and mitigation.
Research suggests that hydrous and repeated mantle melting is key driver of gold enrichment in island arc magmas. The study found that high-degree melting leads to significant concentrations of gold, often several times higher than those found in mid-ocean ridge basalts.
The MountAInWater project uses a unique combination of field work, modeling, and AI to assess climate change impacts on mountain water supplies and identify potential tipping points. The global reanalysis will provide crucial resources for managing future water security challenges.
Researchers investigated the Mississippi River's hydrological trends, ocean carbon storage, and gender dynamics in flood mortality. A study found that precipitation increases, but soil moisture decreases, while high-resolution models reveal stronger Southern Ocean carbon absorption. Additionally, data showed men are overrepresented in ...
Researchers found a surprising correlation between West Antarctic Ice Sheet retreat and marine algae growth over the past 500,000 years. The study suggests that global warming may lead to reduced CO2 uptake if the ice sheet continues to shrink.
A new method developed by Concordia researchers shows how small but widespread snowpack declines can ripple across Canada's water supply. The study found that usable snow water has declined sharply in areas of the Canadian Rockies, affecting a quarter of Canada's land mass and 86% of its population.
The North Atlantic's ocean ventilation has weakened, with water masses aging significantly faster than 30 years ago. This decline in ventilation indicates a slower renewal of deep waters and reduced oxygen transport to depths, potentially impacting marine ecosystems.
Recent research reveals ENSO's influence on tropical Atlantic and Indian Ocean basins, affecting hurricane development and atmospheric circulation. The review also explores the coupling between ENSO and mid-to-high latitude climate systems, including the Atlantic meridional overturning circulation.
Researchers tracked unprecedented ice loss in western Canada, the US, and Switzerland, with glaciers losing 12% of their ice mass between 2001 and 2024. The study found that glacial melt accelerated at an alarming pace, driven by warm, dry conditions and glacial darkening.
The Florida Atlantic University Sensing Institute's SEA Econet network provides accurate rainfall and flood forecasting, supporting public safety during severe weather events. With over 160 atmospheric stations and more than 30 water-level stations across Florida, the network delivers real-time data to inform forecasts and warnings.
Researchers developed a new deep learning framework to predict extreme water levels during hurricanes, enabling smarter decisions and potentially saving lives. The framework, LSTM-SAM, analyzes patterns from past storms to make accurate predictions in areas with limited data, using transfer learning techniques.
The University of Maryland-led study found that the bay experiences 25 days of heat waves annually, with a 10% uptick in recent years. Satellite data shows varying duration and frequency of heat waves across different regions of the bay, highlighting the need for a marine heat wave warning system.
Researchers warn that artificial oxygen input cannot replace comprehensive water protection strategies. Technical approaches have shown promise, but risks include intensifying greenhouse gases and disrupting marine habitats. Climate protection and reducing nutrient inputs remain crucial for mitigating ocean oxygen loss.
Research highlights the impact of wind on wildfire growth, with areas in the US Southeast vulnerable to extreme heat and precipitation events. Meanwhile, a study suggests the 'drought' of EF5 tornadoes may be due to stricter ratings rather than changes in tornadoes.
When two tropical cyclones collide in the Indian Ocean, they can intensify considerably, leading to extreme interactions between the ocean and atmosphere. The study found that effects occurred that have only been observed with much stronger cyclones, including a cooling effect of three degrees Celsius and upwelling of deep water masses.
The UN reports that over 77.6% of the world's land experienced drier conditions in recent decades, with drylands expanding by nearly a third larger than India. This trend is driven by human-caused climate change and has dire implications for agriculture, ecosystems, and people living in affected areas.
Research by Dr. Armineh Barkhordarian finds that Arctic marine heatwaves will become a regular occurrence, with average temperatures rising 2.2 degrees Celsius above seasonal norms. The study suggests that annual heatwaves will be the norm, with significant negative impacts on the ecosystem.
A recent Harvard University study found that soil moisture increased across 57% of the US during summer between 2011-2020, contradicting the assumption that rising temperatures lead to drier soils. Precipitation, rather than temperature, is the primary driver of soil moisture trends.
A study found that underground car parks in Germany, Austria, and Switzerland warm the groundwater throughout the year. The team proposes using geothermal energy and heat pumps to extract excess heat from the ground, which could supply sustainable heat to cities like Berlin.
A multidisciplinary team of scientists conducted a comprehensive study to understand the sources and sinks of plastic debris in the Southern North Sea. Local citizen scientists played a crucial role in tracking the distribution pathways of plastic particles, revealing that two-thirds were washed ashore within 25km of their release site.
Experimental physicists discovered that water impurities become entrapped within icicles, creating chevron patterns and ripple effects. The study reveals that internal patterns are connected to external shapes, leading to a deeper understanding of natural ice formations.
Researchers analyzed fossil corals to reveal changed ocean current circulation patterns. The data supports a scenario where the upper Pacific Ocean was more mixed during the last ice age, contributing to carbon storage and cooler climates.
Researchers study the sea-surface microlayer, a biogeochemical reactor where organisms adapt to harsh conditions like UV radiation and fluctuating temperatures. The team aims to understand biological, chemical, and physical interactions in this thin layer, influencing global climate.
Researchers at the University of Texas at Austin have created a first-ever global river database tracking movement of the world's largest rivers over 40 years. The data reveals average migration rates for each river delta, helping identify stable areas and those experiencing major shifts.
Researchers identify commercialized Membrane Distillation as a green solution for clean, drinkable water. The technique overcomes Reverse Osmosis limitations and provides safe drinking water while managing brines, keeping the environment safe.
