i am a 3rd year geophysics student. first off i would like to say i dont
believe that global warming is a human created problem. that was my belief
before i watched this documentary. it is clear to me that co2 has a very
minimal role in the current period of global warming. first off because
greenhouse gases are not the only mechanism for heating the earth. furthermore
of the greenhouse gases co2 is not actually a very important greenhouse gas.
the most important greenhouse gas by far (over 95%) is water vapour. methane
is also far more important, and a host of other gases. the fact is most of the
co2 produced each year is not anthropogenic and infact of all the co2 produced
each year about 9% is produced by humans, the rest coming from organic life
volcanoes, the ocean etc etc.
now if you think carefully about this the amount of co2 we are producing is 9%
of 0.0054% of the atmosphere thats 0.000486% (less than half of 1000th of the
atmosphere)
now compare the effect that would have to the........... sun!! the utterly
huge themonuclear reaction thats happening all the time. and the important
thing to understand is that the sun is dynamic its constantly in flux and
hectactly changing, both its magnetic and thermal outputs (which both effect
us directly). thus is is not a huge cognitive leap to understand that it is
going to heavily effect our planet accordingly.
i know it is a common thing for people to feel that humans have a special
place in the universe and have a say over most things that we are presented
with. but the fact is when you are dealing with something the size of the sun
we feel very insignificant. and so we should!!!!
now all of the theories presented by global warming are on the assumption that
co2 drives warming of the planet. when infact it is shown that through
geolgical history that this is not the case as well demostrated in this show
that rising/falling co2 levels are driven by the temperature.
i.e
the changing temperature effects the co2 levels far more than co2 effects the
global temperature
this is because as the oceans heat up due to the sun they release co2 (just
like how cola goes flat if you heat it) therefore the co2 levels will closely
match the temperature. however as correctly pointed out in the show the co2
levels follow the temperature rises and are therefor obviously not the cause
of the rise
in the first place.
just so there is no more confusion co2 does not harm the ozone layer. it is
cfc's (chlorofluorocarbon's) mainly found in aerosols and as coolant in
fridges that damages the ozone and is completely different to co2
my last point is co2 is not a pollutant it is a natural gas and you certainly
dont go around polluting everytime you breathe out do you?
