Air pollution is a well-known risk factor for respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). 

In 2024, annual average global air temperatures surpassed 1.5 degrees Celsius above pre-industrial levels for the first time, triggering extreme weather events like record-breaking rainfall and flooding events in the Sahara Desert and extreme summer heat waves across the planet. 

Sometimes, nature’s surprises come with wings. In a new study, scientists pulled from a 35-year dataset to examine long-term population trends of the federally endangered Schaus’ swallowtail butterfly (Heraclides ponceana). 

A new long-term study reveals alarming insights into the impact of climate change on the European beech (Fagus sylvatica), one of Europe’s most widespread and ecologically important tree species.

Scientists have developed a novel tool designed to protect and conserve coral reefs by providing them with an abundance of feeding opportunities. 

Mobile source emissions from roadways near human populations often result in greater health impacts than emissions from industrial facilities in North America [1,2], primarily due to their proximity to densely populated areas and the high exposure to pollutants such as mobile source air toxics (MSATs).

Scientists have discovered microplastics in the snow near some of Antarctica’s deep field camps, revealing how far-reaching plastic pollution has become.

A country of 17,000 islands is at the forefront of a global effort to sustainably feed billions of people in the coming decades.

A corn plant knows how to find water in soil with the very tips of its roots, but some varieties, including many used for breeding high-yielding corn in the U.S., appear to have lost a portion of that ability, according to a Stanford-led study.

After seven months of waiting, La Niña—the cooler sister of El Niño—finally showed up in the eastern Pacific Ocean in early December 2024.
