"The Holocene record of atmospheric CO2 and methane concentrations is an enigma. Concentrations of both gases increased from the beginning of the epoch 11,700 years ago to about 10,000 BP, then declined for several thousand years, but by 6000 BP, concentrations of both gases were steadily increasing again. This mid-late Holocene rise in greenhouse gases is unusual; similar patterns are not observe ...
