Krissansen - Totton explains in more detail: «Having methane and carbon dioxide together is unusual, because carbon dioxide is carbon's most oxidized state, and methane (composed of a carbon atom linked to four hydrogen atoms rather than any oxygen at all) is its least,» he says.

During the Eocene, the concentration of carbon dioxide in the atmosphere was more than 560 parts per million, at least twice preindustrial levels, and the epoch kicked off with a global average temperature more than 8 degrees Celsius — about 14 degrees Fahrenheit — warmer than today, gradually cooling over the next 22 million years.

Today the difference is 28 degrees Celsius, indicating that polar regions are more sensitive to increases in atmospheric carbon dioxide than the tropics.

«Although most of the macrophyte carbon is released back to the atmosphere in the same form that it is assimilated, carbon dioxide, some of it is actually exported to the ocean as dissolved carbon or released to the atmosphere as methane, a gas that has a warming potential 20 times larger than carbon dioxide,» said John Melack, a professor at the University of California, Santa Barbara.

Growth rates for concentrations of carbon dioxide have been faster in the past 10 years than over any 10 - year period since continuous atmospheric monitoring began in the 1950s, with concentrations now roughly 35 percent above preindustrial levels (which can be determined from air bubbles trapped in ice cores).
