Implications of the secondary role of carbon dioxide and methane forcing in climate change : past, present, and future

Description :
This paper addresses 4 issues that are fundamental to the debate concerning the role of CO2 and CH4 greenhouse gases in the forcing of past glacial-interglacial cycles and the role of such forcing for present and future considerations of climate change. In conclusion, the paper stresses that changes in insolation in climatically sensitive zones exceed several-fold the global radiative forcing of climate change by CO2 and CH4, and that local and regional responses to insolation forcing decide the primary climatic feedbacks and changes observed from past glacial-interglacial cycles, and likely to be observed in the future.
