Get ready for smokier air: Record 2023 wildfire smoke marks long-term shift in North American air quality

Phys.org: Earth science - Tue, 01/20/2026 - 21:00

A new analysis of air quality data from the past 70 years shows that Canada's record wildfire smoke in 2023 is part of a broader, continent-wide trend toward smokier skies across North America.

Scientists plan deep-sea expedition to probe 'dark oxygen'

Phys.org: Earth science - Tue, 01/20/2026 - 20:48

A team of scientists announced Tuesday they have developed new deep-sea landers specifically to test their contentious discovery that metallic rocks at the bottom of the ocean are producing "dark oxygen".

Cleaner ship fuel linked to reduced lightning in key shipping lanes

Phys.org: Earth science - Tue, 01/20/2026 - 20:18

Cuts in sulfur emissions from oceangoing vessels have been tied to a reduction in lightning stroke density along heavily trafficked shipping routes in the Bay of Bengal and the South China Sea, according to new research from the University of Kansas.

Previously unknown chemical pathway for air pollution particle formation uncovered

Phys.org: Earth science - Tue, 01/20/2026 - 20:00

An atmospheric scientist at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has helped uncover a previously unknown chemical pathway that plays a major role in the formation of air pollution particles in environments influenced by both natural and human-made emissions—an advance that could reshape how scientists understand air quality and climate impacts.
