Emissions of isoprene, a compound from plant matter that wields great influence in the atmosphere, are up to three times higher in the Amazon rainforest than scientists have thought.

The May 18, 1980, eruption of Mount St. Helens clouded the Pacific Northwest prompted a trove of research for some PNNL scientists.

Clouds in the eastern North Atlantic region will come under scrutiny from a bevy of airplane-based instruments this summer as scientists analyze the physical and chemical properties of clouds and aerosols.

Man-made pollution in eastern China's cities worsens when less dust blows in from the Gobi Desert, according to a new study in Nature Communications.

Organic matter found in vast quantities in oxygen-starved floodplains would yield only minimal energy for hungry microorganisms, which spurn the meal, researchers show in a study in Nature Geoscience.

Small particles of pollution and dust make clouds brighter, and now scientists have figured out a way to better use data to improve our understanding of how this process affects the planet's climate.

High concentrations of tiny pollution particles can invigorate cloud formation and boost snowfall on mountains, according to a new study.

A new window on the Arctic region is opening up, thanks to a new unmanned aerial system that has taken to the skies.

Rick Corley has been honored for his work modeling the full chain of human respiration, from organ, to tissue, to cell, and down to individual molecule.

The rate of plant photosynthesis globally has blossomed this century, according to a new study in the journal Nature by a scientist at the Joint Global Change Research Institute and his colleagues.

A study of mountaintop clouds over Colorado has delivered crucial information to help answer several scientific questions, including how Saharan dust affects clouds over North America.
