We have no idea, for example, how much of the atmospheric carbon being absorbed by the surface of the oceans reaches the bottom, nor how long that takes.
OCO - 2 will also closely monitor the carbon uptake of plants by measuring the weak fluorescence that is produced during photosynthesis as plants» chlorophyll pigments absorb light to capture energy and subsequently re-emit photons at longer wavelengths.
But while scientists and schoolchildren have long known that trees absorb carbon dioxide, no one was sure how significant their role was, overall.

Long story short, the structure of fatty acid determines how fast and well it will be processed by your body: fewer carbons in fatty acids, the faster they will be absorbed in your body.
«Most authors have dismissed this theory with a remark similar to the following quotation from C. E. P. BROOKS (1951): the carbon dioxide theory was «abandoned when it was found that all the long - wave radiation absorbed by CO, is also absorbed by water vapour.»
1) Scientists have long known that greenhouse gases in the atmosphere — such as carbon dioxide, methane, or water vapor — absorb certain frequencies of infrared radiation and scatter them back toward the Earth.
«Arrhenius and Chamberlain saw in this [variations in carbon dioxide] a cause of climate changes, but the theory was never widely accepted and was abandoned when it was found that all the long - wave radiation absorbed by CO2 is also absorbed by water vapor.
But there are wider and more long - lived traces too, in the form of changed patterns of carbon isotopes (absorbed by every living thing) and in tiny, virtually indestructible particles of fly ash released from furnaces and chimneys.
Increased amounts of gases such as carbon dioxide make the atmosphere absorb long - wavelength radiation from the surface more strongly and also emit more radiation back down towards the surface.
to clean energy; yes to dense, beautiful, and affordable communities; yes to safer streets for everyone from children to the elderly; yes to a walkable, bikable, transit - rich transportation system; yes to electric vehicles, internet - speed ride sharing, and the smart grid; yes to wind, solar, and ultra-efficiency; yes to innovation and science and solutions we haven't even imagined yet; yes to restored, carbon - absorbing grasslands, to oceans no longer endangered by acidification, and to towering Northwest forests regrown to once again capture vast quantities of carbon.
The production of food and fibre; the urbanization of once agricultural or forested lands; and the sequestration of that portion of carbon emissions from fossil fuels that is not already absorbed by oceans or by long - term sequestration strategies in agriculture or forestry, all constitute competing or non-overlapping uses of ecosystems.
Additionally the researchers note that the drought frequency paired with longer recovery time could lead to tree death and thus a lowered ability of the region to absorb carbon from the atmosphere, further increasing greenhouse gasses in the atmosphere.
As to the absorption of long - wave radiation from the earth's surface, while it may be true that carbon dioxide and water together do absorb certain frequency ranges of that radiation, I don't think that that matters a whole lot because most of the heat from the surface is transported to the top of the troposphere by conduction, convection and latent heat of vaporization of water during the day.
But during the longer - lasting ones like the Mongol invasion there was enough time for the forests to re-grow and absorb significant amounts of carbon.
He argues that more work is now needed to understand why the fraction of carbon that's absorbed from the atmosphere has stayed so steady for so long.
The longer wavelength (infrared) radiation created there is reflected upwards, and then is absorbed by clouds and the greenhouse gases (GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), etc.).
Water vapor, methane, and carbon dioxide absorb long wave solar radiation, which helps keep the earth warm.
While methane doesn't stay in the atmosphere as long as carbon dioxide, it absorbs 84 times more heat, making it very harmful to the climate.
QUOTE: «As shown on figure 17 - D the regions for absorption and out - gassing are separate; there is no «global» equilibrium between the atmosphere and the ocean; carbon absorbed tens of years ago at high latitudes is resurfacing in up - wellings; carbon absorbed by plants months to centuries ago is degassed by soils Sorry, there is a fundamental lack of knowledge of dynamic systems here: as long as the total of the CO2 influxes is the same as the total of the CO2 outfluxes, nothing happens in the atmosphere.
The same long delays apply to the degassing from the oceanic upwellings that recycle carbon absorbed at higher latitudes tens of years before.
Hydropower dams can contribute to global warming pollution: When a forest is cut down to make way for a dam and reservoir, those trees are no longer available to absorb the carbon dioxide added by fossil fuels.
Scientists have long been aware of a forest's ability to absorb carbon, but a new US study has discovered trees that emit methane.
Indeed, despite the recent problems, the new estimate, published Aug. 19 in the journal Science, suggests that when emissions from the destruction of forests are subtracted from the carbon they absorb, they are, on balance, packing more than a billion tons of carbon into long - term storage every year.
Net primary production (the amount of carbon converted to plant biomass) is far less than what would be absorbed from a natural forest ecosystem, and the carbon does not remain in the system very long.
