The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated. "Climate models must take this carbon sink into account," says Mario Lebrato, lead author of the study. The work was done when he was at the National Oceanography Centre, Southampton (NOCS) and affiliated with the University of Southampton's School of Ocean and Earth Science (SOES); he is now at the...

Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study. As a result, more of the greenhouse gas will be left to concentrate in the atmosphere. "Our findings contradict studies of other ecosystems that conclude longer growing seasons actually increase plant carbon uptake," said Jia Hu, who conducted the research as a graduate student in...

Nation's Forests and Soils Store Equivalent of 50 Years of U.S. CO2 Emissions The first phase of a groundbreaking national assessment estimates that U.S. forests and soils could remove additional quantities of carbon dioxide (CO2) from the atmosphere as a means to mitigate climate change. The lower 48 states in the U.S. hypothetically have the potential to store an additional 3-7 billion metric tons of carbon in forests, if agricultural lands were to be used for planting forests. This...

Tool for estimating size of greenhouse gas-trapping reservoirs to be presented A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs. One strategy for mitigating greenhouse gases is to inject compressed carbon dioxide into natural aquifers made of permeable rock soaked with brackish salt water. Carbon dioxide is less viscous...

A new calculation of Europe's greenhouse gas balance shows that emissions of methane and nitrous oxide tip the balance and eliminate Europe's terrestrial sink of greenhouse-gases Of all global carbon dioxide emissions, less than half accumulate in the atmosphere where it contributes to global warming. The remainder is hidden away in oceans and terrestrial ecosystems such as forests, grasslands and peat-lands. Stimulating this "free service" of aquatic and terrestrial ecosystems is considered...

First year-by-year study, 1765-2008, shows proportion declining The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions"”a finding with potentially wide implications for future climate. The study appears in this week's issue of the journal Nature, and is expanded...

Despite the economic effects of the global financial crisis (GFC), carbon dioxide emissions from human activities rose 2 percent in 2008 to an all-time high of 1.3 tons of carbon per capita per year, according to a paper published Nov. 17 in Nature Geoscience. The paper "“ by scientists from the internationally respected climate research group, the Global Carbon Project (GCP) "“ says rising emissions from fossil fuels last year were caused mainly by increased use of coal but there...

New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected. The results run contrary to a significant body of recent research which expects that the capacity...

Large blooms of tiny marine plants flourish in Antarctic waters left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. This remarkable colonization is having a beneficial impact on climate change. As the blooms die back phytoplankton sinks to the...

New study shows that Arctic has potential to alter Earth's climate In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. Under current predictions of global warming, this Arctic sink could be diminished or reversed, potentially accelerating predicted rates of climate change. In their review paper, David McGuire of the U.S. Geological Survey and the...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
