Sea surface temperatures have less influence on tropical cyclone intensification in the Atlantic than in the Pacific.

Alaska's remote location and vast wilderness contribute both to its beauty and its challenges.

Demeter provides a flexible and repeatable methodology to connect models at varying scales to account for land surface changes.

Open-source tool helps connect high-resolution sectoral models and broader integrated human-Earth system models.

For the first time, researchers have created a gram of yellowcake — a powdered form of uranium used to produce fuel for nuclear power production — using modified acrylic fibers to extract it from seawater.

Changes in water volume tend to be smaller in managed watersheds but occur earlier.

A new study shows that urban heat island effects and increased urban aerosols can spur intense rainfall.

Partnership to initially focus on energy system reliability, aquatic monitoring, underwater technologies, maritime security.

A new modeling approach shows that the ocean circulation determines the varying rate of global temperature response to carbon dioxide.

Novel modeling experiments show that heating near North Africa leads to drying near North America.

A rocket will thunder off from a NASA launch pad this weekend, carrying a handful of seeds that are part of a science experiment in which PNNL plays a key role.

Researchers find surface evaporation drives circulation and summer precipitation in the Tropical West Pacific.

Hurricanes that intensify rapidly do so more strongly and quickly now than they did 30 years ago.

Improving the representation of upper-ocean layers in hurricane forecast models enhances their predictive skill.

Over 100 scientists and engineers from multiple DOE national laboratories and universities, including PNNL, contribute to the creation of a new Earth modeling system—the Energy Exascale Earth System Model.
