New University of Florida research puts to rest the mystery of where old carbon was stored during the last glacial period. It turns out it ended up in the icy waters of the Southern Ocean near Antarctica. The findings have implications for modern-day global warming, said Ellen Martin, a UF geological sciences professor and an author of the paper, which is published in this week's journal Nature Geoscience. "It helps us understand how the carbon cycle works, which is important for...

Emissions of carbon dioxide are causing ocean acidification as well as global warming. Scientists have previously used computer simulations to quantify how curbing of carbon dioxide emissions would mitigate climate impacts. New computer simulations have now examined the likely effects of mitigation scenarios on ocean acidification trends. They show that both the peak year of emissions and post-peak reduction rates influence how much ocean acidity increases by 2100. Changes in ocean pH over...

AUSTIN, Texas, July 29 /PRNewswire/ -- Skyonic Corporation today announced it received $25 million from the U.S. Department of Energy (DOE) to support phase two construction of the Capitol-SkyMine® project, targeted to be the world's first for-profit, commercial carbon capture plant. Utilizing Skyonic's patented SkyMine® CO2 mineralization process, the project will implement new methods for removing CO2 and heavy metals from the flue gas stacks of power...

Much organically bound carbon is deposited on inland lake bottoms. A portion remains in the sediment, sometimes for thousands of years, while the rest is largely broken down to carbon dioxide and methane, which are released into the atmosphere. Swedish researchers have shown that carbon retention by sediment is highly temperature-sensitive and that a warmer climate would result in increased carbon dioxide emissions to the atmosphere. The study is published in the current issue of the journal...

Carbon sequestration Because they can remove carbon dioxide from the flue gases of coal-burning facilities such as power plants, solid materials containing amines are being extensively studied as part of potential CO2 sequestration programs designed to reduce the impact of the greenhouse gas. But although these adsorbent materials do a good job of trapping the carbon dioxide, commonly-used techniques for separating the CO2 from the amine materials "“ thereby regenerating them for re-use...

With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution? A new study by scientists at the Carnegie Institution suggests that while removing excess carbon dioxide would cool the planet, complexities of the carbon cycle would limit the effectiveness of a one-time effort. To keep carbon dioxide at low levels would require a...

Findings released during the annual Goldschmidt Conference at the University of Tennessee, Knoxville As carbon dioxide continues to burgeon in the atmosphere causing the Earth's climate to warm, scientists are trying to find ways to remove the excess gas from the atmosphere and store it where it can cause no trouble. Sigurdur Gislason of the University of Iceland has been studying the possibility of sequestration of carbon dioxide (CO2) in basalt and presented his findings today to several...

Scientists have developed a way to detect and track carbon dioxide deep underground, giving the government an important tool that may help people find a way to keep carbon dioxide and other greenhouse gases from polluting the atmosphere. Scientists at the U.S. Department of Energy's National Energy Technology Laboratory used colorless, nontoxic liquids called perflourocarbon tracers to basically fingerprint carbon dioxide that was injected into a coal seam in northwestern New Mexico. They...

Jeffrey Long's lab will soon host a round-the-clock, robotically choreographed hunt for carbon-hungry materials. The Berkeley Lab chemist leads a diverse team of scientists whose goal is to quickly discover materials that can efficiently strip carbon dioxide from a power plant's exhaust, before it leaves the smokestack and contributes to climate change. They're betting on a recently discovered class of materials called metal-organic frameworks that boast a record-shattering internal surface...
