Danger in the Dust! The Hazards of Windblown Dust
Airborne dust not only causes disease, it also menaces transportation on land, sea, and air; disrupts renewable energy systems; transports pathogens and toxic substances; and poses many other hazards.
Heat Waves: A Growing Threat to Society and the Environment
With heat waves expected to worsen in the 21st century it is essential to take stock of our current understanding, knowledge gaps, and to set research priorities.
Using Cave Formations to Investigate Ancient Wildfires
From sediment cores to speleothems, environmental archives are helping us to understand the history of wildfires.
What We Know and Don’t Know About Climate Tipping Elements
As climate change continues, parts of the Earth system such as ice sheets, frozen soils, or the Amazon rainforest could shift—some quickly, some slowly—after crossing key thresholds or tipping points.
Quantification of Subaerial Volcanism and its Products
Researchers estimate the mass of volcanic products that erupted above sea level from 1980 to 2019 by volcanoes worldwide and the average eruptive rates of each magmatic province.
Why Tropical Forests Are Important for Our Well-Being
Tropical forests play a critical role in supporting human well-being, food security, and the maintenance of biodiversity.
The Seven-Ages of Earth as Seen Through the Continental Lens
The 4.5-billion-year record contained in Earth’s continental crust reveals a seven-phase evolution, from an initial magma ocean to the present-day environment in which we live.
The International Reference Ionosphere – A Model Ionosphere
An accurate and reliable description of Earth’s ionosphere is of critical importance because of our increased reliance on satellite technology and the significant impact the ionosphere has on it.
Rare and Revealing: Radiocarbon in Service of Paleoceanography
While radiocarbon is best known as a dating tool, this rare isotope can also provide unique and wide-ranging insights into the cycling of carbon in the Earth system.
