Carbon Dioxide and the Oceans – temperature controls carbon dioxide, not the reverse.


71% of the earth’s surface is covered by water and large areas of the land are covered by frozen water. Water and water vapour are also significant components of the atmosphere.

The atmosphere and its trace component of carbon dioxide is a very thin skin in close contact with the surface of all of this water. Carbon dioxide is very soluble in water and Henry’s Law says that as the temperature of water changes the quantity of carbon dioxide dissolved in that water will change.

Thus if the sea surface temperature increases, carbon dioxide will be expelled to the atmosphere just like carbon dioxide bubbles are expelled from a warming beer. And as sea surface temperature falls, carbon dioxide will dissolve in the cooling water and this reduces the carbon dioxide in the atmosphere.

This effect can be seen in seasonal, medium term and long term trends.

The seasonal variation in atmospheric content of carbon dioxide is well known, and the huge southern oceans are key players. See the short paper by Bob Beatty on the carbon dioxide cycle at : http://www.bosmin.com/HenrysLaw.pdf [PDF, 689 KB]

When it is winter in the southern hemisphere, the cold surface water of the oceans absorb carbon dioxide and the content of carbon dioxide in the air falls suddenly by about 4 ppm. This is reversed when the southern oceans warm in summer, and the carbon dioxide is expelled from the oceans. (The seasonal summer growth and winter fall of northern hemisphere vegetation adds to this seasonal fluctuation caused mainly by the southern oceans.)

On a medium time scale (21 year moving average) Professor Lance Endersbee published a short paper in August 2008 and he concluded that the oceans regulate the carbon dioxide in the atmosphere and the influence of human-generated carbon dioxide in the atmosphere is negligible. His paper included the following diagram:

On longer time scales, ocean mixing caused by deep ocean currents causes long term changes in ocean temperatures. These changes also affect long term carbon dioxide trends. Carbon dioxide held in large quantities in cold deep ocean water is slowly released as ocean currents mix this cold water with warmer surface water. The reverse occurs as the sea surface cools, absorbs carbon dioxide and the cold dense water sinks to the ocean floor.

The most dramatic evidence of this lagged response comes from ice core data. These show that significant turning points in temperature precede the corresponding turning points in carbon dioxide content in air by between 650 and 1600 years.

Henry’s Law can and has been tested in laboratory experiments. The other data provides additional evidence for the conclusion that the major factor regulating carbon dioxide in the atmosphere, on all time scales, is the temperature of the oceans. Ocean temperature is controlled by solar cycles, cloud cover, ocean currents and undersea volcanism.

Government Science – Cowed and Corrupted by Politics


The Carbon Sense Coalition today claimed that government science bodies in Australia had become cowed and corrupted by politicians.

The Chairman of “Carbon Sense”, Mr Viv Forbes, said that following the lead of the climate alarmists infecting the government owned ABC, CSIRO, BOM and most state and federal science departments were now singing the government song on climate.

“It’s time to de-politicise the Australian government climate science industry.”

South Pacific Sea Level Changes


“The individual sea level records obtained from the SEAFRAME study on 12 Pacific Islands have all been assessed by the anonymous authors of the official reports as indicating positive trends in sea level over all 12 Pacific Islands involved since the study began in 1993. This assessment studies individual records and finds that all of them show no change of sea level in almost all of the records following the 1998 cyclones. It is considered that cyclones and tsunamis not only induce false readings which should be ignored when calculating a trend, but they also disrupt the leveling of the equipment so that previous years’ figures should also not form part of a trend.”

In addition, Cliff Ollier reports:

“Graphs of sea level for twelve locations in the southwest Pacific show stable sea level for about ten years over the region. The data are compared with results from elsewhere, all of which suggest that any rise of global sea level is negligible. The Darwin theory of coral formation, and subsidence ideas for guyots would suggest that we should see more land subsidence, and apparent sea level rise, than is actually occurring. Sea level studies have not been carried out for very long, but they can indicate major tectonic components such as isostatic rebound in Scandinavia. Attempts to manipulate the data by modelling to show alarming rates of sea level rise (associated with alleged global warming) are not supported by primary regional or global data. Even those places frequently said to be in grave danger of drowning, such as the Maldives, Tuvalu and Holland, appear to be safe.”

Here is a the very latest sea Level data from “The South Pacific Sea Level and Climate Monitoring Project” produced by the Australian Government Bureau of Meteorology with technical support from the National Tidal centre and funded by the Australian Agency for International Development. There is no evidence of any dramatic increases in sea levels.
