CO2 IN THE AIRData from US Department of Commerce National Oceanic &Atmospheric Administration NOAA Research shows:

The sudden drop in CO2 mid year coincides with coldersouthern ocean and strong winter winds.

ONE METRE RULE COMPARISON

CO2 at 386 parts per million is equal to justover one third of the first millimetre:

CO2 acts to enrich all forms ofsea, land, plant and animal life

WHERE IS ALL THE CARBON ON EARTH?Refer Prof Ian Plimer “Heaven and Earth” p412

CARBON stores in four areas of the uppermantel including:

What proportions does carbon represent when likened tothe planets of our solar system?

Carbon in the air as CO2 is a relatively small component ofcarbon deposited elsewhere on Earth’s surface.

HOW SOLUBLE IS CO2 IN THE OCEANS?

CO2 enters the ocean in three stages:(1) as a DISSOLVED GAS(2) then as a BICARBONATE and (3) and finally as a CARBONATE. The portions of each are sensitive to waterpH (acid level)

It is fair to say:“CO2 is VERY, VERY, VERY, soluble insea water.”

71% of the World’s surface is water which acts likea huge sponge soaking up then storing CO2

The Carbon Dioxide which dissolves is dependanton the CO2 concentration in the air, and the seatemperature. This is described scientifically as

HENRY’S LAWIn essence Henry’s Law formulated in 1803 means:The quantity of a gas dissolved in a liquid at aparticular temperature is proportional to thepressure of that gas above the liquid.

Similar to a glass of warming beer

And similar to the CO2 dissolved in sea water

A straight line relationship between sea temperature and CO2 is shown toexist by Emeritus Professor Lance Endersbee consistent with Henry’s Law. Refer http://icecap.us/images/uploads/Focus_0808_endersbee.pdf

CONCLUSION

The science fact is that the atmospheric levelof CO2 is always in balance with the seatemperature as postulated by William Henrytwo centuries ago.

It does not matter how much CO2 is pumpedinto the air, it will always find an equilibriumconcentration such as 386ppm, but alwaysdependent on the sea temperature.
