Methanotrophic bacteria consume 30 million metric tons of methane per year and have captivated researchers for their natural ability to convert the potent greenhouse gas into usable fuel. 

A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.

Keeping global temperatures within limits deemed safe by the Intergovernmental Panel on Climate Change means doing more than slashing carbon emissions. It means reversing them.

Childhood phthalate exposure was associated with 20% higher rate of childhood cancer overall

The scientists describe their technique in a paper published today in the journal iSCIENCE.

A new satellite-derived dataset links concentrations of fine particulate matter in air pollution with health outcomes in cities around the world.

A new satellite-derived global dataset links concentrations of nitrogen dioxide with cases of pediatric asthma in urban areas around the world.

A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of extreme global warming known as the Paleocene-Eocene Thermal Maximum (PETM) about 56 million years ago.

Most global carbon-budgeting efforts assume a linear flow of water from the land to the sea, which ignores the complex interplay between streams, rivers, lakes, groundwater, estuaries, mangroves and more. 

Tiny particles in air pollution affect important lipid transport genes in the placenta, showing how exposure may cause conditions like preeclampsia and low birth weight
