  2. Global Warming Cause

    Apparently, the Earth's magnetic field has decreased by 10% in the last 10 years. I'm an electrical engineer. During my studies in sub-atomic physics, I learned that a particles velocity can be effected by magnetic fields. I believe it's possible that more of the Sun's radiation is penetrating the Earth's magnetic field due to it being weaker. If more radiation hits the Earth, shouldn't that also increase the overall temperature of the Earth and can global warming be contributed to this? I've been bouncing this idea in my head for a while now and I can't see why this MAY not be true.

    Your premise is true. Emissions of solar radiation due
    to the increased activity of solar flares in the last couple
    of years means more radiation will enter the Earth's
    surface and beyond. The likelihood that a warming here
    can occur more readily as a result of the solar activity
    becomes even more significant with the unusual number
    of flares that have been seen through various telescopes
    in recent years. It seems to have been the relative large
    sizes of the solar flares that has caught people's attention
    at JPL and elsewhere. Think about why the SPF ratings
    for sunblockers has gone up in the last couple of years
    and you will have a pretty good idea why that is.

    More of same. We're gobbling up the planet. If we don't learn to curtail ourselves, it will be done for us by natural agents, such as new AIDS in New York, antibiotic-resistant TB cultured in Russian prisons, droughts...

    Lack of cooperation is still a major stumbling block. Many do not even have basic civil rights, even now. Man who drove us home from airport recently fled African homeland 9 years ago because the government begain executing the student group he belonged to, because they had the temerity to speak out for a better way (no bombings or other terrorism, just speaking out). Of 1000 refugees in neighboring country at same time, 20 made it with him to America, where he is now a U.S. citizen. First member of family to ever leave home village, as far as they know.

    I think you hit the nail on the head as to why global
    dimming was not the reason for so many deaths in
    Africa. Technically, global dimming will increase
    the amount of moisture in the air, not lessen it. It
    was a lame excuse to use the term drought for so
    many that have perished due to domestic unrest as
    well as pandemics of disease in Africa.

    I am still bewildered that what was required reading
    for us in a Biology 1AT course and was all the craze
    here for a few years that so few people today even
    know of Paul Ehrlich's The Population Bomb book
    and the significance of it, even back in the mid 70's.

    I agree, the central issue we have today is not
    global warming, not the opening and closing
    of the Ozone layer, not the number of times
    I spray a field with a pesticide, not the, I hate
    to write this, the politicians and attorneys but
    we simply have too many people which ties up
    natural resources that are not being replenished
    even remotely at the same rate as the resources
    that are being exhausted, some permanently I
    might add as in the tropical rain forests.

    It's going to be a painful century.
