Astronomers now have a new pair of eyes to detect meteors over Hawaiʻi using a state-of-the-art monitoring system installed on the rooftops of existing buildings on Maunakea and Haleakalā. The high-speed video devices are ...

Bacteria feeding on Arctic algae blooms can seed clouds

New research finds Arctic Ocean currents and storms are moving bacteria from ocean algae blooms into the atmosphere where the particles help clouds form. These particles, which are biological in origin, can affect weather ...

Model development is crucial in understanding climate change

Numerical models are a key tool for climate scientists in understanding the past, present and future climate change arising from natural, unforced variability or in response to changes, according to Dr. Qing Bao, Research ...

Arctic mission will trap scientists in ice to study climate

Cranes hoist cargo onto the deck, power tools scream out and workers bustle through the maze of passageways inside the German icebreaker RV Polarstern, preparations for a yearlong voyage that organizers say is unprecedented ...

Longer summer dry season observed in Congo rainforest

A recently documented long-term drying trend over the Congo Basin could have important implications on the future of the world's second largest rainforest, according to a study published today in Nature Climate Change.

Atmospheric rivers getting warmer along U.S. West Coast

Most of the West Coast of the United States relies on a healthy winter snowpack to provide water through the dry summer months. But when precipitation falls as rain rather than snow, it can diminish summer water supplies, ...

Satellites assisting look into hurricanes
