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.

Scientists have devised a simple new model that explains how the undesirable effects of urban heat islands vary across seasons. Their results could help cities in different climatic regions design heat mitigation strategies.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 51±¬ÁÏ study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

The North Carolina Climate Science Report benefits from the scientific expertise of two Nicholas School of the Environment faculty members.

A team of students from the Nicholas School of the Environment and Pratt School of Engineering has been working for more than a year to create a single digital map of the service boundaries of North Carolina’s drinking water systems.

The ratio of carbon isotopes in three common species of tuna has changed substantially since 2000, suggesting major shifts are taking place in phytoplankton populations that form the base of the ocean’s food web, a new international study finds.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 51±¬ÁÏ study finds.

Predicting if droughts and heat waves will kill forests is difficult, but new work by scientists and engineers at 51±¬ÁÏ, Princeton, Stanford and the University of Alabama (UA) could help scientists spot problems early enough that they can still mitigate the threats and help restore at-risk forests.

Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them precious time in their fight against sea-level rise, ocean acidification and warming temperatures, a new paper by scientists at 51±¬ÁÏ and Fudan University suggests.

With the Environmental Protection Agency (EPA) poised to loosen coal ash rules for dry onsite storage and large fill projects, a new study from 51±¬ÁÏ finds that leaving those contaminants exposed may significantly heighten the risk of toxic contamination to nearby soil and waterways.

Allowing coal ash to be spread on soil or stored in unlined pits and landfills will raise the risk that several toxic elements, including carcinogenic hexavalent chromium, could leach out of the coal ash and contaminate nearby water supplies across the U.S., according to preliminary findings from a new 51±¬ÁÏ study.

Reducing fossil fuel emissions steadily over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing the large spike in short-term warming that some studies have predicted, new analysis by researchers at 51±¬ÁÏ and the University of Leeds finds.
