Hail Causes the Most Storm Damage Costs Across North America
The icy weather phenomenon leads to more than $10 billion in damages each year. Nonetheless, research on hail is lacking, scientists say.
Drones Hunt for Impacts of Oil Exploration on Wetland Emissions
Seismic lines, constructed for petroleum resource exploration, disturb Canadian peatlands, but how can we detect their impact on greenhouse gas budgets?
Major Uncertainty in Estimates of Carbon Trapped in Soil
A new study reveals discrepancies between global databases and field measurements.
Prairies, Potholes, and Public Policy
Studying the Prairie-Pothole Region of North America could help improve water resource management across the continent.
Continental Convection Reaches New Highs
Ten years of high-resolution gridded NEXRAD radar data provide a new data set to quantify tropopause-overshooting convection over the continental United States.
North American Wild Rice Faces Sulfide Toxicity
Researchers have developed a model to inform the regulation of sulfate levels in freshwater environments that are threatening the iconic plant.
A Benchmark for Trace Greenhouse Gases in the Arctic Ocean
Samples of seawater from the North American Arctic show that the region is neither a major source nor sink of methane and nitrous oxide to the overlying atmosphere.
Accounting for Accelerated East Coast Sea Level Rise
An analysis of tide gauge records and physical models shows acceleration of sea level rise on the East Coast due to melting of the Greenland Ice Sheet is especially pronounced south of 40°N latitude.
