Soils are warming quickly and at considerable depth across Alaska, with temperatures rising fastest in the state’s permafrost region, a trend that could accelerate climate change and undermine the stability of roads, buildings and other infrastructure built on the continuously frozen ground.

Cutting greenhouse gas emissions now may limit how much ice Antarctica loses this century and reduce the rise in seas facing coastal communities, according to findings from a new study.

A living laboratory at the University of Hawaiʻi at Mānoa’s Magoon Research and Education Station is exploring ways to cool buildings and homes without expensive electricity bills while increasing local food production.

Irrigation canals form a sort of circulatory system for global agriculture. Across the world, millions of kilometers of human-made canals carry water from lakes, rivers and reservoirs downhill to farmland.

The switch to silicon cells could also halve the weight of the solar cells needed on the spacecraft, freeing mass for fuel or instruments, or cutting launch costs.

For decades, Arctic sea ice has been melting earlier in spring and freezing later in fall, extending the melt season and contributing to widespread ice loss.

Storing energy as heat is a proven pathway to address the challenge solar power faces when it’s dark or cloudy outside by enabling the capture, storage and on-demand release of thermal energy.

As a liquid that is easily stored and transported, ammonia (NH3) is an attractive carrier for hydrogen, which is used in fuel cells, semiconductor manufacturing, chemical processing, and other applications.

Extreme weather events, such as floods, droughts and torrential rains, affect the water quality in lakes, rivers and coastal areas.

Southern California is emerging from yet another round of wildfires just as the wildfire season gets underway.
