Carbon Balance Recorded in Ice Cores

Carbon balance recorded in ice cores, according to an article in BBC News, 28 April 2008. Richard Zeebe from the University of Hawaii in Honolulu has studied carbon dioxide levels in gas bubbles in an Antarctic ice core drilled by the European Project for Ice Coring in Antarctica (Epica). He looked at long term trends and calculated "over a period of 610,000 years the long-term change in atmospheric CO2 concentration was just 22 parts per million (ppm), although there were larger fluctuations associated with the transitions between glacial and interglacial conditions." These results confirm a theory that carbon released from volcanoes is removed from the atmosphere through the weathering of rocks, washed into oceans, and eventually buried in deep sea sediments. He commented: "It is remarkable how exact the balance is between the carbon input from volcanoes and the output from rock weathering. This suggests a natural thermostat which helps maintain climate stability." However, he claims "These long term cycles are way too slow to protect us from the effect of (anthropogenic) greenhouse gases."


Editorial Comment: As the evolutionists don't believe that the world was full of people driving cars or generating electricity in the transitions between glacial and interglacial we wonder where the "larger fluctuations" in carbon dioxide were meant to have come from. The answer is in the article, i.e. from volcanoes, which reminds us that most of the carbon dioxide in the atmosphere still comes from natural, rather than man-made sources. However, since governments cannot tax volcanoes or boss them around, it is not surprising we don't hear much about them. This study also shows that the overall amount of carbon dioxide has been kept relatively stable. The apparent slowness of these cycles depends on the uniformitarian belief that the ice core is 610,000 years old. If the age was only a few thousand, then the cycles would be a lot faster. (Ref.
