Warming temperatures are causing a steady rise in copper, zinc, and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams ...
Wildfires are a growing threat to the boreal north, especially under the rapidly changing climate. IIASA researchers modeled and analyzed how climate change may impact future burned area in boreal forests and highlighted ...
The warming climate shifts the dynamics of tundra environments and makes them release trapped carbon, according to a new study published in Nature. These changes could transform tundras from carbon sinks into carbon sources, ...
Arctic and boreal latitudes are warming faster than any other region on Earth. In three new studies, Earth system scientists at the University of California, Irvine report how the ecosystems in these regions are changing.
Permafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern ...
The U.S. set aside 23 million acres of Alaska's North Slope to serve as an emergency oil supply a century ago. Now, President Joe Biden is moving to block oil and gas development across roughly half of it.
Modern biology textbooks assert that only bacteria can take nitrogen from the atmosphere and convert it into a form that is usable for life. Plants that fix nitrogen, such as legumes, do so by harboring symbiotic bacteria ...
When you throw dinosaurs into the mix, sometimes you find that a rule simply isn't.
They didn't exist a century ago but today PFAS "forever chemicals" contaminate the environment from groundwater to Antarctic snow to turtle eggs, and concern over their possible toxicity is growing.
Recent studies have shown that rising atmospheric CO2 concentrations and consequential warming may compromise the community structure and functioning of the cold tundra ecosystems. However, in addition to carbon uptake, natural ...
