The use of small, controlled burns to clear out flammable underbrush has saved thousands of giant sequoias from devastating wildfires, new research finds.

New research led by University of Hawai‘i (UH) at Mānoa atmospheric scientists found that the century-old yardstick used across many industries to estimate air-conditioning and refrigeration energy demand — called cooling degree days — is missing something fundamental.

As artificial intelligence (AI) drives a global surge in data centres in Canada and around the world, a less visible but increasingly urgent challenge is growing alongside it.

In recent summers, wildfire smoke has been inescapable across Wisconsin, drifting south from Canada and leading to long stretches of poor air quality.

Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice loss and its contribution to sea level rise.

Catalysts that convert waste carbon dioxide into valuable products such as acetate are designed to run continuously on electricity for the conversion process. 

New research shows the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. 

Human activities are fundamentally altering the chemical makeup of local coral reefs, according to a study led by the University of Hawaiʻi at Mānoa and published in Nature Communications. 

The mountain jewelflower inhabits a wide swath of California and Oregon, from summer-scorched foothills to high mountains where snow falls during winter.

Since the first major bleaching event in 1996, Hawaiian corals have been subject to increasing heat stress and more prevalent bleaching events.
