The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru's Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.
An international team of geologists, headed by members of the University of Bern, has shown for the first time that the Swiss Alps are being lifted faster than they are being lowered through erosion—and are thus growing even higher. To do this, the researchers quantified the erosion of the Alps with the help of isotopes measured in the sand of more than 350 rivers throughout the European Alps. These isotopes are formed by cosmic rays and bear information on the Earth's surface erosion.
Decades after two large earthquakes rocked the Mojave Desert in California, the discovery of new post-earthquake displacement features has prompted KAUST researchers to update the existing model for this earthquake-prone region. Their findings support a thin "crème brûlée" model in which the strength lies in the upper crust, while the lower crust exhibits more ductility over time than previously thought.
China will ban all waste imports from January 1, 2021, state media reported Friday, marking the culmination of a three-year phase-out of accepting overseas junk.
A team from the Institut national de la recherche scientifique (INRS) and the Institut national de santé publique du Québec (INSPQ), led by Professor Fateh Chebana, has recently developed a cold-health watch and warning system for cold waves, a first in the world. Their results were published in November 2020 in the journal Science of the Total Environment.
A team of international scientists led by ETH researcher Paolo Sossi has gained new insights into Earth's atmosphere of 4.5 billion years ago. Their results have implications for the possible origins of life on Earth.
University of Copenhagen researchers have been following vegetation trends across the planet's driest areas using satellite imagery from recent decades. They have identified a troubling trend: Too little vegetation is sprouting up from rainwater in developing nations, whereas things are headed in the opposite direction in wealthier ones. As a result, the future could see food shortages and growing numbers of climate refugees.
As the days shorten and temperatures drop in the northern hemisphere, leaves begin to turn. We can enjoy glorious autumnal colours while the leaves are still on the trees and, later, kicking through a red, brown and gold carpet when out walking.
New Zealand has more than 1,100 registered quarries. Some of these mined sites are small, rural operations, but a significant number are large and complex, and within a city's urban boundaries.
An enormous iceberg, called A-68A, has made headlines over the past weeks as it drifts towards South Georgia in the Southern Ocean. New images, captured by the Copernicus Sentinel-1 mission, show the berg is rotating and potentially drifting westwards.
Mongolia's semi-arid plateau may soon become as barren as parts of the American Southwest due to a "vicious cycle" of heatwaves—that exacerbates soil drying, and ultimately produces more heatwaves—according to an international group of climate scientists.
Destructive volcanic mudflows, huge clouds of volcanic ash that ground flights, and catastrophic floods when natural glacial lake dams fail—these are all examples of the dramatic interactions between volcanoes and glaciers. To help others study, and hopefully predict, dangerous glaciovolcanic activity, researchers have created a new database that combines existing global data.
Last week, a progress report from the New York Declaration on Forests announced that the world is not on track to meet the declaration's goals to reduce forest loss and promote sustainable and equitable development. The report identifies lack of transparency as one of the main barriers to progress, and calls for greater involvement of civil society and grassroots movements while planning and implementing large-scale development projects.
Accurate forecasting and the evacuation of several hundred thousand people helped avert any loss of life after a cyclone clobbered southeast India, authorities said Thursday, as rescuers worked to restore power and clear fallen trees.
A powerful cyclonic storm hurtled into India's southern coast early Thursday, uprooting trees and packing strong winds and rains as tens of thousands of people took refuge in shelters.
Russian oil giant Rosneft on Wednesday announced the start of operations for its giant Vostok oil project in the Arctic, part of the country's strategic energy plan which has been criticised by environmentalists.
Twice as much freshwater is stored offshore of Hawai'i Island than was previously thought, according to a University of Hawai'i study with important implications for volcanic islands around the world. An extensive reservoir of freshwater within the submarine southern flank of the Hualālai aquifer has been mapped by UH researchers with the Hawai'i EPSCoR 'Ike Wai project. The groundbreaking findings, published in Science Advances, reveal a novel way in which substantial volumes of freshwater are transported from onshore to offshore submarine aquifers along the coast of Hawai'i Island.
Regional air-sea coupling plays a crucial role in modulating the climatology and variability of the Asian summer monsoon. The Weather Research and Forecasting (WRF) model, which is a community regional climate model, has been widely used for regional climate studies over Asia.
Although it is a widely known scientific fact that infectious diseases emerge and re-emerge due to climate change, a study which included the involvement of the UAB published in PLOS ONE reveals that 48.9% of the population surveyed are not aware of this relation.
With the culmination of a five-year effort to gather a breadth of geospatial data and display it on an interactive digital atlas, the four main islands of the Federated States of Micronesia are now more easily researched than any other island in the Pacific, including Hawaii, Guam, and Fiji.
