re: Yahoo about 1 in 20,000 parts changing to CO2.
Yes & No.
Yes, a 1/20,000 mixture of cyanide would likely kill you.
First - most people have no idea whatsoever that the CO2 that we are pumping into the atmosphere is not really changing it except on a miniscule scale. (let's exclude particle pollution, completely different topic).
the 1/20,000 I am referring to is, w/o looking it up right now, is the CO2 ppm from about 330 to 380. 50/1,000,000. CO2 is about 400ppm but there has been no warming since 1997 and there was no human caused warming from 290-300. 290 was when "things were perfect" back in 1880.
So do any of those other 20,000 parts matter? No, the "scientists" would tell you the 19,999 parts were in perfect equilibrium before 1880. At the end of the LIA, when the climate was just right. Water vapor is not well-mixed and by many accounts is the dominant greenhouse gas. The number i get is worldwide it averages about 1-2%. Let's say 150 parts per 20,000 is water vapor. The physics of the absorption bands of CO2 vs Water Vapor is beyond us non-physicists. But I have read many articles which discuss the lab experiments that show the overwhelming abundance of water vapor dominants the greenhouse effect because it is present at an ave of 15,000 ppm(1.5%) vs 400 ppm or it is concentration is about 400x of CO2. There are also many other "problems". The CO2 greenhouse effect apparently had already become "saturated" at a lower concentration. And adding more, does nothing. Of course even the greenhouse theory may be a invalid theory in itself. Meaning, that is not how our planet is kept warmer than space. I don't know, there are physicists and scientists who believe the greenhouse theory to be invalid, but they are in the minority. I have no opinion and that science is too complex for a laymen to even ponder what's true.
So yes, 1/20,000 can make a difference in a lot of things. But likely it makes a very, very tiny difference when you consider the many other factors. The #1 fact is the preponderance of El Nino's from late 1970's through 1998. Certainly they had an effect. Other huge factors are even the IPCC carbon cycle graphs show that only 3% of CO2 "emissions" are from humans. 97% are from the oceans, land use changes, decomposition and other natural factors that have absolutely nothing to do with fossil fuels. And the biggest factor of all are ocean cycles which absolutely dominant changes in climate on a decadal scale. Then add the sun (controversial), planetary alignment, changes in magnetic poles of the earth, possible changes in orbit or rotation of earth, even cosmic rays. Oh, and I forget to add another really BIGGIE - Clouds. Roy Spencer says a 1% decrease in cloud cover may have caused this "great warming". Oh and add ocean salinity too to the mess. They all may?? have an effect. No one really knows.
So NO, it is extremely, extremely doubtful that a 1/20,000 change in the atmosphere has anything or at most very little to do with temperature change. And the 1/20,000 i'm cherry picking. But the early 20th warming, although taken as human caused global warming, is accepted as likely to be due to changes in solar irradiance. Even what i consider the "quacks" don't blame global warming on humans before 1960. Of course, many believe that ALL Climate Change is caused by humans, golly, they even adopted the word.
So the more one looks into the this, the more insignificant and unlikely that 1 in 20,000 parts of the atmosphere changing to CO2 has anything to do about anything. Saying, that, the YES of the Yahoo, apparently it makes the marijuana grow better.
