Greening Earth

  1. Oct 2, 2006 #1
    I think that I mentioned here sometimes that more CO2 would mean more biomass and that the annual fosil fuel use would produce enough carbon to reforest an area as big as France.

    Guess what's happening:

    The earth is greening

    The northern hemisphere is greening. Specifically above 40 degrees North latitude.

    The contributing factors are temperature and longer growing season. Spring is coming earlier, and Summer is staying longer. Richer atmospheric CO2 is a factor as well, but not as great a factor as climate change.

    Although it has been updated June 8, 2006, it is essentially an excerpt from this article published September 4, 2001.

    What I find intriguing is the possibility of utilizing the increased growing season to help absorb the increase of CO2 from carbon emissions. More trees are welcome.

    This could be an opportunity for new technologies being developed to utilize bio-mass and carbon sequestration in the production of hydrogen, diesel, and fertilizers.

    Has there been a corresponding increase in marine and fresh-water algae? Of the total carbon fixed by plants by photosynthesis, only about ten percent is by terrestrial green plants--trees, grass, moss, etc.

    Drought conditions weaken the resistance of plants making them more susceptible to disease and insects.

    According to a study about to be released, we may be in for a dry century.


    Whether or not one agrees with the science, the entire earth will suffer the consequences.

    In the case of the northern pine forests in Canada the consequences are more of a result of warmer temperatures. Drought is not the culprit in the northern regions. The beetle that is causing the "browning" is simply rebounding in a lack of cold weather. What is needed is a solid 2 weeks of 40 below (C) to interupt their lifecycle and reduce their numbers. 40 below (C) was, at one time, the norm for winter temps all across the north. With that norm being changed there is the threat of the northern pine beetle spreading throughout the forests of the region all the way to the Atlantic Seaboard.
