Asian monsoon much older than previously thought
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, reports an international research team led by a University of Arizona geoscientist.
Textbook theory behind volcanoes may be wrong
In the typical textbook picture, volcanoes, such as those that are forming the Hawaiian islands, erupt when magma gushes out as narrow jets from deep inside Earth. But that picture is wrong, according to ...
Coral organisms use minuscule appendages to control their environment, stirring up water eddies to bring nutrients
Conventional wisdom has long held that corals—whose calcium-carbonate skeletons form the foundation of coral reefs—are passive organisms that rely entirely on ocean currents to deliver dissolved substances, ...
Mystery solved: 'Sailing stones' of death valley seen in action for the first time
(Phys.org) —Racetrack Playa is home to an enduring Death Valley mystery. Littered across the surface of this dry lake, also called a "playa," are hundreds of rocks – some weighing as much as 320 kilograms ...
Big snowstorms will still occur in Northern Hemisphere following global warming, study finds
If ever there were a silver lining to global warming, it might be the prospect of milder winters. After all, it stands to reason that a warmer climate would generate less snow.
Over 500 gas plumes found to be bubbling up in the ocean along the eastern US coast
Expedition uncovers subglacial life beneath Antarctic ice sheet
The first breakthrough paper to come out of a massive U.S. expedition to one of Earth's final frontiers shows that there's life and an active ecosystem one-half mile below the surface of the West Antarctic ...
Study finds possible link between Arctic change and extreme mid-latitude weather
Plate tectonics: What set the Earth's plates in motion?
The mystery of what kick-started the motion of our earth's massive tectonic plates across its surface has been explained by researchers at the University of Sydney.
Tornadoes occurring earlier in 'Tornado Alley'
Peak tornado activity in the central and southern Great Plains of the United States is occurring up to two weeks earlier than it did half a century ago, according to a new study whose findings could help ...
Early Earth less hellish than previously thought
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates.
Specialized species critical for reefs
One of Australia's leading coral reef ecologists fears that reef biodiversity may not provide the level of insurance for ecosystem survival that we once thought.
Gas leaks from faulty wells linked to contamination in some groundwater
A study has pinpointed the likely source of most natural gas contamination in drinking-water wells associated with hydraulic fracturing, and it's not the source many people may have feared.
Future increases in snowfall will not prevent retreat of glaciers on the Antarctic Peninsula
(Phys.org) —Dr Nicholas Golledge, a senior research fellow at Victoria's Antarctic Research Centre, is part of an international team of researchers studying a small glacier on James Ross Island, near the ...
