Mangrove ecosystems rank among the most efficient "blue carbon" systems on Earth, capable of absorbing and storing vast quantities of atmospheric carbon dioxide (CO2). However, mangroves also release methane (CH4), a potent greenhouse gas, potentially offsetting a portion of their climate mitigation benefits.... Read more

"Off Target," "Broken Record," "Closing Window": the UN Environment Program's flagship reports have been warning for years that emissions must fall faster to avoid dangerous climate impacts—but is the world listening?... Read more

Every day, people and all other living organisms are potentially exposed to dozens or even hundreds of chemicals—from plastics and pesticides to cosmetics and cleaning agents. While each chemical may individually meet safety standards, their combined effects can quietly add up.... Read more

Aging lead-pipe drinking water systems, along with the public health measures implemented to reduce their risks, are reshaping the chemistry and health of nearby urban streams. New research from University of Pittsburgh biogeochemists, hydrologists, and environmental engineers has uncovered previously overlooked environmental impacts of a common water treatment practice: adding...
