Carbon dioxide is increasing in concentration in the earth's atmosphere because the part of the carbon cycle when [CO.sub.2] is being released is greatly exceeding the amount being sequestered in plant tissue.
In this section is described a little known, but important contributor to the global carbon cycle, the algae (Emiliania huxleyi).
A large portion of the carbon dioxide emitted when humans burn fossil fuels, for instance, is taken up and stored in the ocean via a set of processes that make up the ocean carbon cycle. But, the rapid rate at which carbon dioxide emissions are increasing means the future of the cycle is uncertain, especially when many of the key processes remain poorly understood.
According to a paper the scientist wrote, published in the journal (http://advances.sciencemag.org/content/3/9/e1700906) Science Advances , mass extinctions occur when changes in the carbon cycle happen too quickly and too heavily for Earth's living creatures to adapt to them.
The 2013 colloquium included a researcher workshop during the second week titled "Key Uncertainties in the Global Carbon Cycle: Perspectives across Terrestrial and Ocean Ecosystems." The objectives of the workshop included identifying important, cross-cutting problems in carbon-cycle science common to land and ocean communities.
Carbon Dioxide Utilisation: Closing the Carbon Cycle
LOS ANGELES (CyHAN)- NASA's Orbiting Carbon Observatory-2, or OCO-2, is designed to study the global carbon cycle from a whole new perspective.
The roles of the atmosphere and lithosphere are discussed in detail as is the increasingly vital topic of the carbon cycle in light of current global warming.
Sequestration may be questionable fiscal policy, but it's good news for the carbon cycle. Vast underground networks of fungi may sequester heaps of carbon in boreal forest soil, a study suggests.
"It is significant because it shows that animals can have a big influence on the carbon cycle," said Wilmers, assistant professor of environmental studies.
Desperate for certainty about the carbon cycle and how it affects climate, they've been grappling with concepts such as 'parts per million', 'feedback loops', 'C[O.sub.2] equivalents' and 'carbon sinks: Reliance on the media for clarity has just added to the confusion: most journalists don't understand it either.
The EPA made the right decision, based on the evidence that burning trees to meet our nation's voracious energy appetite may disrupt the balance of the carbon cycle. Greenhouse gas reporting will expose the heavy carbon burden of burning wood to make energy.
