The mechanism for reducing anthropogenic global warming, initiated through radiative forcing of greenhouse gases, is to stop emissions and reduce their concentration in the atmosphere to levels which do not stimulate carbon feedbacks.

Page 2 of 23 Duncan Steel: Perihelion precession, polar ice and global warming Introduction Record melting of Arctic sea ice over the past year (Schiermeier 2012) has been widely presumed to be a consequence of anthropogenic global warming (AGW), and yet a natural mechanism exists that may be responsible, at least in part.

Especially because the proof of anthropogenic global warming is not at all very sound and, if there is such a thing, its mechanisms and parameters are mostly still unclear.

Based on an extensive literature review, we suggest that (1) climate warming occurs with great uncertainty in the magnitude of the temperature increase; (2) both human activities and natural forces contribute to climate change, but their relative contributions are difficult to quantify; and (3) the dominant role of the increase in the atmospheric concentration of greenhouse gases (including CO2) in the global warming claimed by the Intergovernmental Panel on Climate Change (IPCC) is questioned by the scientific communities because of large uncertainties in the mechanisms of natural factors and anthropogenic activities and in the sources of the increased atmospheric CO2 concentration.
