Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands’ carbon storage and reduce the amount of greenhouse gases they release back into the atmosphere during dry periods by up to 90%, a 91ÉçÇø¸£Àû study finds.

A new 91ÉçÇø¸£Àû study finds that municipal waste incinerators' legacy of contamination could live on in urban soils.

Brian R. Silliman, Rachel Carson Distinguished Professor of Marine Conservation Biology at 91ÉçÇø¸£Àû’s Nicholas School of the Environment, has been elected a Fellow of the Ecological Society of America (ESA).

Duke leaders rise to face the challenges of climate change.

The National Science Foundation and the Paul G. Allen Family Foundation have awarded a $1.2 million grant to support a new initiative aimed at boosting ecosystem restoration and climate resilience along North Carolina’s coast.

Rewetting and restoring 250,000 acres of southern pocosin peatlands that had been drained for farming but now lie fallow could prevent 4.3 million tons of climate-warming carbon dioxide, now stored in their soils, from oxidizing and escaping back into Earth’s atmosphere each year, a 91ÉçÇø¸£Àû study shows. That amount equals 2.4% of the total annual reductions in CO2 emissions needed for the United States to be carbon neutral by 2050.

Mixing toxic coal ash into acid mine drainage may sound like an odd recipe for an environmental solution, but a new 91ÉçÇø¸£Àû-led study finds that it can neutralize the drainage’s dangerously low pH and help reduce harmful impacts on downstream ecosystems—if you use the right type of ash. Using the wrong type of ash can create new contamination and not tame the drainage’s extreme acidity.

Human activities such as marsh draining for agriculture and logging are increasingly eating away at saltwater and freshwater wetlands that cover only 1% of Earth’s surface but store more than 20% of all the climate-warming carbon dioxide absorbed by ecosystems worldwide. A new study published May 5 in Science by a team of Dutch, American and German scientists shows that it’s not too late to reverse the losses.

Coastal marshes that have been invaded by feral hogs recover from disturbances up to three times slower than non-invaded marshes and are far less resilient to sea-level rise, extreme drought and other impacts of climate change.

By distinguishing between lead from modern sources and lead from pre-1970s vehicle exhaust fumes and leaded paint, the new test may be especially useful for assessing the hidden risks of legacy contamination.

Clouds of smoke and ash from wildfires that ravaged Australia in 2019 and 2020 triggered widespread algal blooms in the Southern Ocean thousands of miles downwind to the east, a new 91ÉçÇø¸£Àû-led study by an international team of scientists finds.

Warming waters along the Western Antarctic Peninsula have led to declines in the diversity and distribution of the region’s plankton population and its ability to absorb climate-warming carbon dioxide from the atmosphere.

Joel Dunn (MEM’04) Helps Create America’s First National Marine Sanctuary in 20 Years

Recent Duke grad Alexandra DiGiacomo (BS ’20) is using drones to better understand how rising seas, warming waters and rapid development are killing protective saltmarshes at our coast, and what can be done to reverse the losses.

Sixteen years after the restoration of Upper Sandy Creek began, hundreds of species, some rare, now call the once-heavily eroded and degraded stream home, and nitrogen pollution flowing off Duke’s campus into downstream waters has been slashed by 75%.
