Study quantifies role of legacy phosphorus in reduced water quality

For decades, phosphorous has accumulated in Wisconsin soils. Though farmers have taken steps to reduce the quantity of the agricultural nutrient applied to and running off their fields, a new study from the University of Wisconsin–Madison reveals that a “legacy” of abundant soil phosp

Vicious circle of drought and forest loss in the Amazon

Logging that happens today and potential future rainfall reductions in the Amazon could push the region into a vicious dieback circle. If dry seasons intensify with human-caused climate change, the risk for self-amplified forest loss would increase even more, an international team of

Dartmouth Study Finds Increased Water Availability from Climate Change May Release More Nutrients into Soil in the McMurdo Dry Valleys of Antarctica

As climate change continues to impact the Antarctic, glacier melt and permafrost thaw are likely to make more liquid water available to soil and aquatic ecosystems in the McMurdo Dry Valleys, potentially providing a more nutrient-rich environment for life, according to a Dartmouth stu

New evidence that tropical ice caps existed in the Andes

Scientists have long suspected that ice caps formed repeatedly in the tropical Andes during the late Pliocene, but only evidence of a single glaciation was known until now. A study by SFU earth scientists Nicholas Roberts and John Clague as well as René Barendregt from the University
