Carbon Sink - Trends in Sink Performance

Trends in Sink Performance

According to a report in Nature magazine, (November, 2009) the first year-by-year accounting of this mechanism during the industrial era, and the first time scientists have actually measured it, suggests "the oceans are struggling to keep up with rising emissions—a finding with potentially wide implications for future climate." With total world emissions from fossil fuels growing rapidly, the proportion of fossil-fuel emissions absorbed by the oceans since 2000 may have declined by as much as 10%, indicating that over time the ocean will become "a less efficient sink of manmade carbon." Samar Khatiwala, an oceanographer at Columbia University concludes that the studies suggest "we cannot count on these sinks operating in the future as they have in the past, and keep on subsidizing our ever-growing appetite for fossil fuels." However, a recent paper by Wolfgang Knorr indicates that the fraction of CO2 absorbed by carbon sinks has not changed since 1850.

Famous quotes containing the words trends in, trends, sink and/or performance:

    Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.
    Johan Huizinga (1872–1945)

    Power-worship blurs political judgement because it leads, almost unavoidably, to the belief that present trends will continue. Whoever is winning at the moment will always seem to be invincible.
    George Orwell (1903–1950)

    But you must pay for conformity. All goes well as long as you run with conformists. But you, who are honest men in other particulars, know, that there is alive somewhere a man whose honesty reaches to this point also, that he shall not kneel to false gods, and, on the day when you meet him, you sink into the class of counterfeits.
    Ralph Waldo Emerson (1803–1882)

    Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.
    —G.C. (Georg Christoph)
