    Global Warning

    Global warming is real.
    The evidence is obvious.
    Not only the polar icecaps, but the mountain icecaps are
    starting to melt, according to one report from South
    America.

    So what is the reason?
    My conclusion is the destruction of the forests.
    Trees are our natural ‘air’ conditioners.
    They not only absorb carbon dioxide but also exhale oxygen.
    Another very important factor is that they absorb tremendous
    amounts of solar energy that contributes to cooling the
    Earth. This free oxygen that we breath comes from the
    vegetation, such as the trees.
    If we do not make any changes, Our planet will be bald in
    the future and we will be walking around with oxygen tanks
    for surviving. Although the surface temperature appears to
    be close to normal, the upper atmosphere has increased to
    explain the melting at the poles and mountain tops.
    So we must immediately stop cutting down trees and
    start ‘planting’ trees instead.
    Many rivers originate at these mountaintops.
    So these rivers will dry up to cause people to abandon their
    Current environments.

    We can substitute concrete, iron, aluminum and plastics for
    housing and outdoor furniture.
    This would also eliminate the use of poisons that are being
    used to kill the termites that destroy wood.
    These poisons contaminate he under ground waters that
    will eventually leech into the local rivers and lakes by
    osmosis.

    Science poetry. Fun!

    Important to get your facts right.
    The first paragraph of your 'poem' is fine. However, you may care to note the following.

    1. Globally forest acreage is increasing. This is mainly due to first world countries planting more forest. At the same time, some third world nations, like Indonesia, are destroying vital forest. So deforestation is a local problem, rather than global.
    2. We are not going to run out of oxygen. Any reduction in oxygen levels in the atmosphere are miniscule, and not noticeable by oxygen breathers. In fact, the CO2 increase is not noticeable by oxygen breathers. It is the greenhouse effect that is the issue.
    3. I agree with planting trees, but this is unlikely to have much effect on global climate change for the reasons given above.

    Actually the most comprehensive studies show a net loss. This one points to a loss of more than 50 million hectares of forest in the past ten years. Global Forest Resources Assessment

    Though these studies usually consider replanting trees as reforesting, it takes centuries for an area of replanted trees to come anywhere close to the range of habitat found in a natural forest.

    This one always bothered me: "We can substitute concrete, iron, aluminum and plastics for
    housing and outdoor furniture." Those alternatives are all very energy intensive. Only a tiny fraction of forest cutting is for lumber, most is wasted for clearing burning as firewood, or other uses such as making paper.

    While I'm at it this one to: "Although the surface temperature appears to be close to normal, the upper atmosphere has increased to explain the melting at the poles and mountain tops."
    The upper atmosphere is actually cooling, its one of the smoking guns for increased green house gases. Even the highest mountains barely penetrate the middle atmosphere including those at the poles.

    Don't get me wrong though. Even being technically incorrect doesn't condemn the message or the sentiments that many of us feel.

    As the Earth turns into a fiery hell as global warming alarmists predict, all of human life and human civilization will burn to a crisp burned to the planet's surface. Many people believe that global warming is caused by emissions of CO2 in the atmosphere mankind.

    You are making neither a comment on the poem or a scientifically supported observation.

    Actually, wood is the way we want to build large scale to combat CO2. Concrete production is a substantial source of anthropogenic CO2. If we use trees for permanent structures, we have sequestered CO2. When we replant what we have cut down, the young trees consume CO2 far faster than older trees. Do this on a large enough scale, it it will make a noticeable decrease.

    Great poem Cosmo. On the subject of global warming, there was an interesting article in the May Issue of Discover magazine that proposed that agricultural soils could help reduce 13% of the atmosphere's CO2. It seemed like an interesting idea, 13% may not seem like a large percentage, but it really is. Here's a link to the article:
