Too bad you skipped common sense class and humor 101 though... I was making fun of the way that republicans downplayed the seriousness of the BP oil spill by saying that the thousands of gallons a day are no big deal since "this happens naturally all the time" which took an actual factual thing like trace seepage and applied it to a fucking disaster, much like saying "pfff, cuts bleed all the time, this will heal" to a severed femoral artery.
. Isn't it funny how icehouse periods here on Earth last onaverage for less than 1 million years. FYI, an icehouse earth is when there areicecaps present on the poles so we are technically an icehouse earth right now.Permanent ice is actually a rare phenomenon in the history of the Earth,occurring only during the 20% of the time that the planet is under an icehouseeffect. This means that the earth has had a much more significant amount of CO2in its atmosphere at one point in time than we do now. There is even evidencethat the Earths icehouse-greenhouse cycle during the Permian period had CO2levels that fluctuated between 250 parts per million to 2,000 parts permillion. The burning of fossilized fuels is not thought to be the cause for theperiods CO2 fluctuations, which kind of makes sense seeing as how humansweren't around during that period.
So the CO2 fluctuations have to be related to eithera.)something that the Earth naturally does by itself on a cyclical basis,b.)the Earths eccentricity cycle (orbiting the sun), or c.)by a combination ofthe two. My best bet is that it is a combination of the two simply because ofthe incredible difficulty at assessing what causes the transition between anicehouse earth to a greenhouse earth and vice-versa. The history of everyglobal system here on Earth, the history of the suns solar output, and thehistory of the Earths eccentricity path would have to be accurately recordedbecause all of these things can contribute to the rise and fall of carbonlevels and global temp.(associated with the transition between the two states).And I’m not talking thousands of years or even millions; I’m talking about thetime when the Earth started to develop an atmosphere 4.6 Billion years ago. Conductingall of this data at pinpoint accuracy would virtually be impossible to do rightnow because the technology to do so simply does not exist. If you don't believeme than go find me the history of the suns solar output and where the Earth wasat on its eccentricity path in relation to the suns solar output at any giventime and if their is any relation to the two (hint...probably no relation atall, but then again we have know idea). Note that you would also have to tiethis sun-earth data into all of the data representing the history of thesystems here on earth... Only when we can do all of this, than we can start todraw conclusions because we will then be able to tell what factor/factors mademajor contributions to the transition between greenhouse and icehouse statesand to all of the changes attributed with these transitions (melting ice caps,shift in geological processes, temp variations, etc...).
