Climate change caused by ocean, not just atmosphere, new Rutgers study finds

Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.

But in a new study published in Science, a group of Rutgers researchers have found that circulation of the ocean plays an equally important role in regulating the earth's climate.

Climate change impacts countered by stricter fisheries management

Climate change impacts countered by stricter fisheries management

A new study has found that implementing stricter fisheries management overcame the expected detrimental effects of climate change disturbances in coral reef fisheries badly impacted by the 1997/98 El Niño, according to the Wildlife Conservation Society.

Satellite catches lingering remnants of Tropical Depression 9

Satellite catches lingering remnants of Tropical Depression 9

NOAA's GOES-East satellite has been keeping an eye on the remnants of Tropical Depression 9.

On Oct. 24 at 14:30 UTC (10:30 a.m. EDT) GOES-East captured a visible image of clouds and thunderstorms associated with former Tropical Depression 9,, centered over the southeastern Yucatan Peninsula of Mexico, Belize, and the adjacent northwestern Caribbean Sea.

New insights on carbonic acid in water

New insights on carbonic acid in water

Though it garners few public headlines, carbonic acid, the hydrated form of carbon dioxide, is critical to both the health of the atmosphere and the human body. However, because it exists for only a fraction of a second before changing into a mix of hydrogen and bicarbonate ions, carbonic acid has remained an enigma. A new study by Berkeley Lab researchers, has yielded valuable new information about carbonic acid with important implications for both geological and biological concerns.

New study finds options for climate change policy are well characterized

WASHINGTON – October 24, 2014 – Policy options for climate change risk management are straightforward and have well understood strengths and weaknesses, according to a new study by the American Meteorological Society (AMS) Policy Program.

"Large gaps remain in society's consideration of climate policy," said Paul Higgins, the author of the study. "This study can help in the development of a comprehensive strategy for climate change risk management because it explores a much larger set of policy options."

Icelandic volcano sits on massive magma hot spot

Spectacular eruptions at Bárðarbunga volcano in central Iceland have been spewing lava continuously since Aug. 31. Massive amounts of erupting lava are connected to the destruction of supercontinents and dramatic changes in climate and ecosystems.

Li-ion batteries contain toxic halogens, but environmentally friendly alternatives exist

Physics researchers at Virginia Commonwealth University have discovered that most of the electrolytes used in lithium-ion batteries — commonly found in consumer electronic devices — are superhalogens, and that the vast majority of these electrolytes contain toxic halogens.

At the same time, the researchers also found that the electrolytes in lithium-ion batteries (also known as Li-ion batteries) could be replaced with halogen-free electrolytes that are both nontoxic and environmentally friendly.

Liquid helium offers a fascinating new way to make charged molecules

A collaboration between researchers at the Universities of Leicester and Innsbruck has developed a completely new way of forming charged molecules which offers tremendous potential for new areas of chemical research.

Bodies at sea: Ocean oxygen levels may impact scavenger response

An ocean's oxygen levels may play a role in the impact of marine predators on bodies when they are immersed in the sea, according to Simon Fraser University researchers in a new study published this week in the journal PLoS One.

SFU criminologist Gail Anderson led the study, based on the deployment of a trio of pig carcasses into Saanich Inlet at a depth of 100 metres and studied over the past three years. Anderson assessed scavenger activity while co-author and SFU criminologist Lynne Bell continues her investigation of what happens to submerged bones.

New experiment provides route to macroscopic high-mass superpositions

University of Southampton scientists have designed a new experiment to test the foundations of quantum mechanics at the large scale.

Standard quantum theory places no limit on particle size and current experiments use larger and larger particles, which exhibit wave-like behaviour. However, at these masses experiments begin to probe extensions to standard quantum mechanics, which describe the apparent quantum-to-classical transition.
