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.

Slashing emissions of carbon dioxide by itself isn’t enough to prevent catastrophic global warming, a new study shows. But if we simultaneously also reduce emissions of methane and other often overlooked climate pollutants, we could cut the rate of global warming in half by 2050 and give the world a fighting chance.

Using satellite images, scientists have detected hundreds of very large and previously unreported methane releases at oil and natural gas production sites across the globe.

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.

Harnessing the power of artificial intelligence, satellites and field observations, Duke researchers have produced new estimates of how much photosynthesis and primary production – key components in the global carbon cycle – are occurring in Earth’s oceans, and how these processes may be changing in response to a changing climate.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

The stringent lockdown imposed by the Chinese government to slow the spread of COVID-19 early this year significantly eased the strain on hospitals there. Admissions due to non-COVID respiratory illnesses decreased by nearly 5,000, a new study by an international team of scientists shows.

91ÉçÇø¸£Àû researchers have developed a new online calculator that teachers, administrators and students can use to estimate the risk of airborne transmission of the COVID-19 virus in classrooms.

By providing the first estimate of how much hydrogen is available to fuel microbial life in the sunless sub-seafloor crust beneath the Mid-Ocean Ridge (MOR), a new 91ÉçÇø¸£Àû-led study sheds light on one of Earth’s least understood biospheres.

Pollution declines from pandemic shutdowns may aid in answering long-standing questions about how aerosols influence climate.

Global methane levels have hit an all-time high after what appears to be a near-record yearly atmospheric increase in the potent greenhouse gas.

New NOAA analysis highlights an alarming trend; experts call for curbing pollution from oil and gas wells

Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.
