Climatic and CH4 cycle implications of glacial-interglacial CH4 change in the Vostok ice core

Strong evidence from analysis of the Vostok ice core is presented that CH4 concentrations increased from 0.34 to 0.62 p.p.m.v. between the end of the penultimate ice and the following interglacial, about 160-120 kyr B.P. This CH4 change may be explained by considering the effect of the climatic chan...

Description
Summary:Strong evidence from analysis of the Vostok ice core is presented that CH4 concentrations increased from 0.34 to 0.62 p.p.m.v. between the end of the penultimate ice and the following interglacial, about 160-120 kyr B.P. This CH4 change may be explained by considering the effect of the climatic change on the CH4 cycle. Its contribution to the global climatic warming is estimated to be about 25 percent that due to CO2. (C.D.)
