Despite improvements, China's air remains unsafe

Fine particulate matter (PM2.5) and ozone exposure are major public health problems in China. Although useful, atmospheric models used to analyze these and other air quality concerns over the years are expensive to run, limiting ...

Defects in quartz crystal structure reveal the origin of dust

Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, ...

Coastal marsh migration may further fuel climate change

As rising sea levels cause marshes to move inland in six mid-Atlantic states, the coastal zone will not continue to serve as a carbon sink but release more carbon into the atmosphere, a new modeling study led by researchers ...

Hydrology controls lithium isotopes in rivers and seawater

Seawater lithium isotopes (δ7Li) record changes over Earth history, including a ~9‰ increase during the Cenozoic, which is interpreted as the reflection of either a change in continental silicate weathering rate or weathering ...

Chinese scientists help Africa combat land degradation

Chinese scientists released an online tool, the Great Green Wall Big Data Facilitator, to help African countries combat increasingly severe land degradation on June 16, the 28th World Day to Combat Desertification & Drought.

Crossing fire threshold can quickly turn blazes dangerous

Global climate change has already exacerbated the risk of fire and is likely to fuel even more change as accelerating feedback loops create disastrous consequences for both biodiversity and human populations. Yet accurately ...

Droughts in the sixth century paved the way for Islam

Extreme dry conditions contributed to the decline of the ancient South Arabian kingdom of Himyar. Researchers from the University of Basel have reported these findings in the journal Science. Combined with political unrest ...

Predicting rainfall futures

Despite decades of research, what will happen to rainfall in years to come remains unknown, and severe floods as well as prolonged droughts are already defying expectations.

Understanding the nature of big earthquakes

Songqiao "Shawn" Wei, an Endowed Assistant Professor of Geological Sciences in the Department of Earth and Environmental Sciences in the College of Natural Science at Michigan State University has been studying the earthquakes ...

Giving metal to microbes could reduce greenhouse gas

Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully "digest" food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless ...

Steep mountain slopes have surprisingly long lifetimes

Gravity and rock physics say slopes steeper than about 30°—known as the critical threshold angle, or the angle of repose—shouldn't really exist, yet they do. These steep slopes and near-vertical cliffs can be seen in ...

Study finds change in Niobrara's nutrients following 2019 flood

Rivers transport important nutrients across landscapes and into larger bodies of water. Among those nutrients are nitrogen and phosphorous, which stimulate the growth of crops but, when accumulating in water, may also yield ...
