Tropical Rain Forests Regulate Variations In Atmospheric Carbon Dioxide Levels

RainforestA NASA Earth Exchange (NEX) study published in the journal Proceedings of the National Academy of Sciences discovered that a temperature anomaly of only 1ºC leads to an annual 3.5 Petagram anomaly in the annual CO2 growth rate, equivalent of 1/3 the annual global emissions of the burning of fossil fuels and deforestation together.

The results of the study, which comprise a 50-year analysis based on temperature and rainfall patterns during the El Niño years, give scientists a new toolkit to make sense of the Earth’s carbon cycle as it experiences changes due to human activities. The team and its leader, Dr. Weile Wang, analyzed data gathered between 1959 and 2011 on atmospheric carbon dioxide concentration and global air temperature.

There is a strong link between fluctuating seasonal CO2 levels and tropical temperatures over the past 50 years, and scientists have discovered that temperature changes are more important than rainfall changes in the concentration of atmospheric CO2.

Researchers discovered that despite major Earth events like fire, flooding, earthquakes, and El Niño, among others, the Earth’s system has been remarkably consistent in regulating variations in atmospheric carbon dioxide levels.

Annual changes in temperatures over the tropical rainforests act with the absorption of carbon dioxide and the release of carbon dioxide, the two important mechanisms that naturally regulate year-to-year changes in atmospheric CO2 concentrations.

  1. GLOBAL WARMING MAY NOT BE MAN MADE
    Dr. Larry Vardiman (scientist and physicist) of the Institue for Creation Research says:
    “One possible scenario may be found
    in a recent series of articles by Henrik Svensmark and Nigel Marsh,
    cosmic ray specialists from Denmark, who have shown an indirect
    connection between galactic cosmic ray (GCR) intensity and global
    temperature.7,8,9 They are studying the influence of the Sun on the flow
    of GCR to Earth. The Sun’s changing sunspot activity influences the
    magnetosphere surrounding the Earth permitting more GCR to strike the
    Earth during high periods of activity.
    When the Sun is active, the intensity of GCR striking the Earth is
    increased, causing more ionization in the atmosphere, creating more
    carbon-14, and possibly creating more cloud condensation nuclei (CCN).
    This increase in CCN, in turn, appears to create more low-level clouds
    which cool the Earth. When the Sun is quiet the GCR intensity striking
    the Earth is reduced, allowing the Earth to warm. Svensmark and Marsh
    have shown a striking statistical correlation between sunspot activity
    and global cooling and warming over the past 1000 years.
    The recent rise in global temperature may partially be due to
    current low solar activity supplemented by a recent increase in carbon
    dioxide concentration measured at Mauna Loa. The connection which still
    needs further study is the production of CCN and clouds by GCR.” 
    There is a good deal of science showing that global warming is not
    mad made. Yes, we still should have pollution controls, as we already
    do, but not to the extreme because it will unnecessarily hurt business.
