An international group of researchers has demonstrated that branching complexity of rivers affects regional population stability and persistence in nature, contrary to current theories which suggest the importance of an ecosystem’s size.

Supervolcanoes are one of Mother Nature’s deadliest phenomena, and when they erupt, they can change the climate of the entire planet.

Landmark study shows how heavy, short rain storms are intensifying more rapidly than would be expected with global warming.

The oceans are the planet’s most important depository for atmospheric carbon dioxide on time scales of decades to millenia. But the process of locking away greenhouse gas is weakened by activity of the Southern Ocean, so an increase in its activity could explain the mysterious warmth of the past 11,000 years, an international team of researchers reports.

New IIASA-led research has found that a single climate mitigation scheme applied to all sectors, such as a global carbon tax, could have a serious impact on agriculture and result in far more widespread hunger and food insecurity than the direct impacts of climate change. Smarter, inclusive policies are necessary instead.

Tropical Depression 16W formed in the northwestern Pacific Ocean despite vertical wind shear. Wind shear was elongating the newly formed tropical depression when NASA's Terra satellite passed overhead and analyzed the storm in infrared light. 

Native American communities actively managed North American prairies for centuries before Christopher Columbus' arrival in the New World, according to a new study by researchers from Southern Methodist University and the University of Arizona.

President Thomas Jefferson, who founded Coast Survey in 1807, commissioned Lewis and Clark’s Corps of Discovery Expedition in 1803, the first American expedition to cross the western portion of the contiguous United States.

The persistent drumbeat of warm temperatures around the world last month made for the fifth warmest June on record and the first half of the year the fourth warmest for the planet.

The Global Precipitation Measurement mission or GPM core satellite provided a rainfall and cloud analysis on powerful Typhoon Jongdari as it moves toward Japan. Jongdari follows another powerful typhoon that made landfall in Japan earlier this year.
