Most geochemists are surprised at the discovery from ice core measurements that the atmospheric concentration of carbon dioxide was about 180 atm during the most recent ice age. Thus, it seems unlikely that fluctuations in this cycle would have contributed significantly to the observed atmospheric increase of 75 atm in carbon dioxide over the past two centuries. Measurements of the amount of carbon dioxide trapped in air bubbles in ice cores show that atmospheric concentrations varied by at most, 10 atm in the millennium prior to the Industrial Revolution.
CARBON CYCLE OCEAN SERIES
Geochemists generally assume that any changes in the natural carbon cycle that have occurred over the past two centuries have contributed in only relatively minor ways to the observed increase in atmospheric carbon dioxide. The Slow Carbon Cycle Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil. Most of the carbon released from fossil fuels will end up in the oceans, where a complex cycle of circulation and other processes controls its fate.
Throughout the text observational data is integrated with basic physical theory to address. The ocean plays an important role in the anthropogenic carbon dioxide budget. In the new paper, he has developed a simple mathematical model to represent the carbon cycle in the Earth’s upper ocean and how it might behave when this threshold is crossed. ocean carbon cycle and its interaction with the atmosphere.
