Trace metals are nutrient elements, like zinc, that animals and plants need in small amounts to function properly. Animals generally get trace metals in their diets or through environmental exposures, while plants take their trace minerals up from soil. If we get too little, we may experience a deficiency, but...

Wetlands are Earth's largest natural source of methane, a potent greenhouse gas that is about 30 times more powerful than carbon dioxide at warming the atmosphere. A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) analyzed wetland methane emissions data across the entire Boreal-Arctic region... Read more

Oxygen is fundamental to sustaining life on Earth. The ocean gets its oxygen from its uppermost layers in contact with the atmosphere. As our planet continues to warm, the ocean is gradually losing its capacity to absorb oxygen, with severe consequences on marine ecosystems and human activities that depend on... Read more

A new study, resorting to computational models, predicts that a subduction zone currently below the Gibraltar Strait will propagate further inside the Atlantic and contribute to forming an Atlantic subduction system—an Atlantic ring of fire. This will happen 'soon' in geological terms—in approximately 20 million years.... Read more

Africa's forested areas—an estimated 14 % of the global forest area—are continuing to decline at an increasing rate—mostly because of human activities to convert forest land for economic purposes. As natural forests are important CO2 and biodiversity reservoirs, this development has a significant impact on climate change and affects the... Read more

The Amazon rainforest could approach a tipping point, which could lead to a large-scale collapse with serious implications for the global climate system. A new Nature study by an international research team including scientists from the Potsdam Institute for Climate Impact research (PIK) reveals that up to 47% of the... Read more

Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.... Read more

Ribbons of water vapor called atmospheric rivers wind through the troposphere, moving the planet's moisture from near the equator toward the poles. These aerial waterways are responsible for about 20%–30% of the annual rain and snow in parts of Europe and the United States and more than 40% in East... Read more
