Theoretical analysis reveals flow variations that happen over longer time periods affect a plume’s spread and center of mass.

Knowing which bacteria in a community are involved with carbon cycling could help scientists predict how microbial carbon storage and release could influence future climate dynamics.

Extreme sea levels will become 100 times more frequent by the end of the century around the world, according to a new study.

A new study shows that, when starved, some trees turn to self-digestion before dialing down energy storage.

A new research partnership between PNNL and the University of Nevada, Reno aims to tackle critical challenges such as climate change, infrastructure resilience and cybersecurity.
