Significant reliance on land-based methods of carbon dioxide removal can protect biodiversity by avoiding climate impacts - but it could also compete with biodiversity protection unless there is better site selection, according to a new study.

Seventy percent of soils in Europe are contaminated with pesticides. 

Flue gas is exhausted from home furnaces, fireplaces and even industrial plants, and it carries polluting carbon dioxide (CO2) into the atmosphere.

For decades, scientists knew there was a huge swath of undetected and unaccounted for per- and polyfluoroalkyl substances (PFAS) in the atmosphere, often referred to as PFAS dark matter, but no one knew how much was missing or how to measure them.

To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020.

Agricultural waste that is usually burned or left to rot could play a far bigger role in tackling climate change if it were instead used in long-lasting building materials, according to new research from the University of East London (UEL).

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.

PFAS, or per- or polyfluoroalkyl substances, are ubiquitous in modern life. First produced at the end of World War II, these chemicals are in everything from furniture and cosmetics to food packaging, non-stick pans and clothing.

Thousands of U.S. deaths per year linked to particulate matter from wood smoke.

Even after the disastrous L.A. wildfires abated last year, the danger from smoke persisted for many people living nearby.
