  • The Greening Of The Earth...

    As world populations grow, isn't this a good thing?


    Carbon Dioxide Fertilization Greening Earth, Study Finds

    From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.

    An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite data from NASA’s Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf area index, or amount of leaf cover, over the planet’s vegetated regions. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.

    ...Results showed that carbon dioxide fertilization explains 70 percent of the greening effect, said co-author Ranga Myneni, a professor in the Department of Earth and Environment at Boston University. “The second most important driver is nitrogen, at 9 percent. So we see what an outsized role CO2 plays in this process.”

    Wouldn't the "greening" use up the extra CO2 and create a new balance?

      It should help, just not enough. Theoretically it helps the warming too in that more plant life tends to produce cooler temperatures where the plants are. Again, just not enough.

        Well: The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.

        That seems like quite a lot, and the greening may be exponential as we get warmer. So I'm not sure how much we want to slow down the warming, especially with a growing population and the need for more food.

          I don't know if there is a balance or ever was. The planet was once much greener/warmer. And with the growing population we may need much more vegetation and longer growing seasons.

            I think the problem is that while it might produce more crops in certain areas, other areas will become deserts and you would lose crops. Also more and bigger storms are supposed to happen because of global warming.

              No I don't think the desert thing happens, the more warming the more moisture in the atmosphere from the oceans. There is still an over all gain of vegetation. Perhaps by large amounts.

                You'd have to look at how much CO2 is sequestered by that additional vegitation, vs how much is being input per year.

                Bottom line, the measured CO2 content of the atmosphere is going up. monotonically. That value represents the sum of all the inputs to the atmosphere and all the processes that can pull CO2 out. We don't have to know what they all are to know that there isn't enough CO2 sinks to compensate for what is being put into the atmosphere.

                So it is not enough.

                  That is not the point - the fact is an overall warmer earth may be more beneficial, on so many levels, than a cooler earth.

                          Just means more real estate opportunities for beach front property farther inland. And we get rid of the worst part of California and New York. Seems like a win/win.

                            That is an interesting thing. Since the industrial age do we really know how much the oceans have risen?

                              The fact is the rise will be so slow relocation will solve any possible loss of life.
