Climate Change

Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study published this month. The work is published in the Journal of Advances in Modeling Earth Systems.... Read more

The California state Department of Water Resources has started using laser and sonar technology to measure reservoir capacity, determining that Lake Oroville, the State Water Project's largest reservoir, has shrunk since its creation in 1960.... Read more

Melting Arctic glaciers are in rapid recession, and microscopic organisms colonize the newly exposed landscapes. Dr. James Bradley, Honorary Reader in Arctic Biogeochemistry in the School of Biological and Behavioral Sciences at Queen Mary University of London, and his team, have revealed that yeasts play an important role in soil...

Understanding the dynamics of rainfall-runoff in mountainous terrains is vital for refining predictions of sediment-related hazards, which are becoming increasingly critical under the influence of climate change. Despite extensive flood monitoring in various mountainous locales globally, comprehensive data from areas characterized by high-relief have been limited primarily to smaller watersheds,... Read more

Severe wildfires increase with a decrease in prescribed burns—but new research shows that in some places across the United States there may be fewer opportunities to safely burn in the future.... Read more

With record rainfall projected to continue into the future, many worry extreme flooding will follow suit. But a new CIRES-led study published today in Science of the Total Environment found an increase in precipitation alone won't necessarily increase disastrous flooding—instead, flood risk depends on how many days have passed between...

A team of physicists, geologists and signal theorists from the University of Granada, Spain, has developed a machine-learning-based algorithm designed to predict when Mount St. Helens will erupt.... Read more

Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard... Read more

A study led by a UC Riverside atmospheric scientist predicts that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator.... Read more

Who knew Earth's upper atmosphere was like alphabet soup? NASA's Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionosphere.... Read more

The study focuses on the so-called Intertropical Convergence Zone (ITCZ), a low-pressure trough near the equator whose position and intensity changes seasonally with the position of the sun. Trade winds from the northern and southern hemispheres meet here. This results in heavy cloud formation and heavy rainfall. To analyze how... Read more

Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes.... Read more

Accurate estimates of atmospheric greenhouse gas levels are needed to understand and address the drivers of climate change. Of particular interest is atmospheric methane, which has increased in concentration by 160% since preindustrial times and accounted for 35% of warming from greenhouse gases from 2010 to 2019....

The Lancang Mekong River Basin (LMRB) connects six countries in Southeast Asia. To support the ecological, economic and social sustainable development of the LMRB, low carbon management services need to be implemented in each country within the basin. However, there is still a lack of a science-based, effective assessment framework... Read more

It's hard to imagine a cycling season without the contributions of Geo-Sports.org. After the successful editions of previous years, the sports commentaries for the Tour stages will once again be supplemented with mini-lectures.... Read more
