    Hello there,

    I am a student studying in th UK, i am 15 years old and recieved news the other week of beig invited to a science masterclass in Iceland. Today i recieved my letter from the organisation that is organising it, amongst this i found that some work had to be submitted to enable me to go iceland on this oppertunity of a lifetime trip. I was given a short article telling me that, "a young boy is confused about reporters saying that global warming is caused by Humans, but he would like to know wether it is created by humans or is it a natural occurance"

    So in a summary i need the following to be observed:
    Who do you feel is causing it
    What has caused it (even if humans have caused it)
    Figures to analyse
    Evidence to back up thoeries
    Arguments to looks at
    Pointers To Look At

    I really want to go on this trip, i have been told i am allowed to askfor help and is not "cheating" it is merely using common sense, all i really need is your beliefs and views upon global warming or even post some reference sites.[/B]

    You help is much abliged
    Sam


    For those of you that wish to know how far i have got so far, so i have proof im not just expecting you to do all the work look below:

    Found a few earth temparature readings from intervals of 3 years, spanning for a total of 20 years. i have also started planning my opinion on global warming and desicribed in brief what global warming is.


    PS: Please excuse the spelling and grammer at this moment in time, been looking all day for data etc.

    Who do you feel is causing it
    Like most things it has many factors. Increased solar radiation. Increased amounts of greenhouse gases in our atmosphere. Decreased vegitation. Etc.


    What has caused it (even if humans have caused it)
    The things listed above, however it's not certain how much each contributes.

    Figures to analyse
    Evidence to back up thoeries
    Arguments to looks at
    Pointers To Look At
    Google global warming or greenhouse gases, I'm too busy to hook you up with a power point presentation. Take note of droughts and the ice caps melting and bizarre weather this year. I'd also stick to information from ESA or NASA and scientific journals.

    Good luck kid.

    Ya it seams to be a mixture of things, it's not 100% because of humans even if we do play a large role. Living in Phoenix it's amazing how much all this concrete holds in the heat, it's like a giant brick bake oven that stays warm all night long. I have to wonder something is such factors don't play in at all. Even to a small degree.

    Just take the Bush administrations stance. What global warming ?

    Before most massive climate changes, large amounts of "dirt" have been found in the atmosphere. While Im sure those dreaded cfc`s and other such related items have had some impact on the climate, I think there is something a lot more important thats been missed out.

    The fact that our magentosphere is going through a phase at roughly the same time as a climate change bears more investigating I think.

    There is no observable correlation between climate change and magnetic pole reversals. What are you suggesting we investigate?

    That I honestly believe im right.

    Im busy doing a lot more research on it, but there definitly seems to be signs of climate changes been closely associated with things "wobbles", seismic activity (specificly increased volcanic activity). Concentrated air contminents... Yes.. i have the specifics, but let me first write it out in a way thats "acceptable" to you in the academic world.

    One thing I have learnt recently, is that "popular opinion" is most often wrong, and that any deviations from popular opinion by a "proffesional" in the field will get bashed down by over presumptious egos (not a good evolutionary trait). You find that annoying attitude in all walks of life sadly.

    Please note, that that above paragraph was not intended for those with helpful critique.

    Anyways, let me put everything together in an understandable logical way for your later ripping apart. I made a couple of assumptions earlier on that are incorrect or I took them in the wrong context.
    I have honestly learnt a massive amount of information in studying this closer and some of the links and information people have offered me have been extremely useful.

    Now I need to get back to reading on the Maloshivik (dont have the reference on hand, so that, like most of this post, is likey to be spelt wrong) cycles, before I can post my theory in any effective detail.

    Is there evidence to suggest they didnt happen?

    Yes. The fact that there is no correlation between them. Pole reversals and wanders happen regardless of and apparently independent of climate changes.

    If they were graphed together, you would see no pattern or correlation that could be considered even coincidental, much less causational.

    There is, however, growing evidence that temporary reduction in the magnetosphere's effectiveness in dampening cosmic ray bombardment may influence mutations in DNA, prompting some speciation. This is just barely out of the speculation phase, but could be a source of punctuated equilibrium.

    There is definately no link between pole shifts and climate. This remains the fantasy of myster-mongers and significance-junkies.

    The thing with the pole reversals is that the magnetic field decreases before it flips. As it decreases we are exposed to more and more solar radiation that would not have reached the surface otherwise because of its deflection by the magnetic field. More radiation, higher temperature.

    I'm saying this sure of its contribution, however, I have no idea how much of a contribution it is. I'm guessing a relatively minor one when compared to decreased vegitation, increased greenhouse gas composition in the atmosphere, and increasing solar output.

    Its a logical assumption until you consider that it isn't the solar radiation that would be absorbed by the atmosphere or Earth's surface. The sort of radiation that is deflected by the magnetosphere is that of cosmic rays, which are comprised of protons and alpha particles. This energy doesn't store up in the atmosphere or surface the way UV radiation or longwave radiation from the Earth itself.

    Well, what exactly is the solar wind made of, because that's one thing the magnetic field protects us from?

    Composition of the Solar Wind:
    The composition of the solar wind is a mixture of materials found in the solar plasma, composed of ionized hydrogen (electrons and protons) with an 8% component of helium (alpha particles) and trace amounts of heavy ions and atomic nuclei: C, N, O, Ne, Mg, Si, S, and Fe ripped apart by heating of the Sun's outer atmosphere, that is, the corona.

    SOHO also identified traces of some elements for the first time such as P, Ti, Cr and Ni and an assortment of solar wind isotopes identified for the first time: Fe 54 and 56; Ni 58,60,62 [Galvin].

    Note that although the solar wind is electrically balanced, the solar wind consists almost exclusively of charged particles (stripped away nuclei from atoms) and is an excellent electrical conductor. These electrically conducting particles is technically known as a plasma, so it may be misleading to think of the solar wind as like Earth "winds".
