Smoke from forest fires might contribute to more than half of certain gritty air pollution events in the continental U.S. during the summer, and as much as 20 percent of those events throughout the year, according to new research at The University of Alabama in Huntsville (UAH).

Every year, millions of tonnes of plastic debris ends up in the sea - a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers.

The strong El Niño event of 2015-2016 provided NASA and NOAA an unprecedented opportunity to test the effectiveness of the newest observation tool to measure global atmospheric carbon dioxide concentrations -- NASA’s Orbiting Carbon Observatory-2 satellite or OCO-2.

Observations of carbon dioxide concentrations over the tropical Pacific from the satellite were validated by data from NOAA’s Tropical Pacific Observing System of buoys, which directly measure carbon dioxide concentrations at the surface of the ocean.

When it comes to oysters and their role in reducing nutrient pollution, a new study by researchers at William & Mary’s Virginia Institute of Marine Science gets right to the guts—and the shell—of the matter.

Saline levels dropped 10 percent in one day over parts of Flower Garden Banks

As devastating wildfires continue to rage in the western U.S. and Canada, a team of environmental engineers at Washington University in St. Louis have discovered that light-absorbing organic particulate matter, also known as brown carbon aerosol, in wildfire smoke loses its ability to absorb sunlight the longer it remains in the atmosphere.

Pharmaceuticals, including antibiotics, are an increasingly common pollutant in water systems, said Catherine Hui Niu, associate professor in the Department of Chemical and Biological Engineering at the University of Saskatchewan.

Officials from Lakehead University and the International Institute for Sustainable Development Experimental Lakes Area (IISD-ELA) have signed a five-year memorandum of understanding to foster collaboration between the two organizations.

Diarrheal disease from contaminated water is the second leading cause of death among children under the age of five, claiming more than 360,000 lives annually. Now, a new study of children in 35 countries finds that those living in a watershed with more trees had a lower risk of contracting the illness.

Excess solar flux could be harnessed and used to generate additional electricity at a tower CSP plant, by cladding part of the tower containing the receiver with photovoltaic (PV) panels, according to Sandia scientist Cliff Ho. He found that adding PV on the tower could generate over 10 MW, or 10% of the total capacity of a 100 MW CSP plant, using the same reflected sunlight off heliostats used to focus “suns” up onto the tower receiver for thermal solar generation.
