Stern Review: the Economics of Climate Change analyzed the impact of climate change from a special angle. This paper gives an introduction to and analysis of its standpoint, methods, and results from five aspects: science basis, economic issues of climate change, policy of greenhouse gas reduction and its economic factors, costincome analysis of adaptation, and implication of global response activities to climate change. Stern Review agreed that climate change is really true. If human society developed as usual pattern, global surface temperature would rise with 2~3℃. Stern Review addressed that this wonld lead global economic loss with 5%~10% of GDP. In poor countries, their loss wonld exceed 10% of GDP. If human society takes some measures to keep the concentration of greenhouse gas in the range of 450×10^-6~550×10^-6before 2050, the cost of reduction will account for 1% of GDP. Stern Review also suggested that: a carbon price, technology policy, and the removal of barriers to behavioural change are essential to mitigation, and leaving out any one of these elements will significantly increase the costs of action and that global cooperation and adaptation activities are feasible for economy and climate objectives.
