As with any biomass fuel, any
carbon dioxide produced when the reed is burnt was extracted
from the air when it grew, so producing and burning it does not
add carbon dioxide to the atmosphere.
But climate modelers can't
add enough
carbon dioxide (a planet - warming greenhouse gas) to their Mars atmosphere models to get the temperature high enough to keep water
from freezing.
While this controls the amount of
carbon dioxide they're absorbing, it has the
added outcome of limiting the amount of water released into the air
from plants.
While the United States and Europe are responsible for the vast majority of the
carbon dioxide added to the atmosphere through the industrial era, the International Energy Agency foresees more than 90 percent of the growth in such emissions coming
from developing countries, led by China.
Essentially, China and India, the emerging giants in the global greenhouse, are saying that any extra costs for them to divert
from established trajectories for
carbon dioxide emissions as they pursue prosperity must be covered by the established industrial powers, which still have many times greater emissions on a per - capita basis and spent a century freely
adding greenhouse gases to the atmosphere in building their wealth.
Environmental groups have sought to force the federal government to restrict
carbon dioxide emissions using the Clean Air Act, the Endangered Species Act (because of threats to polar bears
from global warming) and other federal laws, and now they are poised to
add the Clean Water Act to the list.
This
adds up to a staggering 10 billion tons of
carbon dioxide emission each year
from cars alone.
That could
add up: an earlier LA Times investigation (h / t DeSmogBlog), based on data
from Friends of the Earth, counted up at least 12 billion tonnes of
carbon dioxide from just a subset of the projects the two funded in 1993 - 2006.
Researcher Wang Mou
from the Chinese Academy of Social Sciences outlined a planetary
carbon budget in which
adding 2,771 gigatons (a gigaton equals one billion tons) of
carbon dioxide to the atmosphere above the level in 1900 would still keep the average global temperature below the 2 degree Celsius threshold.
Dr Solomon and her colleagues peg the 2000 - 2009 cooling effect at about a third of the opposite effect they would expect
from the
carbon dioxide added over the same decade, and only a bit more than a twentieth of the warming expected
from the rise in
carbon dioxide since the industrial revolution.
George is convinced that by
adding iron sulphate to the oceans, he can stimulate plankton blooms and so suck enough
carbon dioxide out of the atmosphere to offset human emissions
from burning coal and oil.
By most estimates it will take 1000 years
from the time we stop
adding carbon dioxide to the atmosphere for the oceans and the atmosphere to come into equilibrium.
The
carbon dioxide capture facility is configured to transfer
carbon dioxide from a gas to the portion of the growth medium to yield an enriched growth medium, such that the concentration of dissolved
carbon dioxide in the enriched growth medium exceeds the concentration of dissolved
carbon dioxide in the growth medium, where dissolved
