The Stern Review, led by Sir Nicholas Stern, warns of the global economic consequences of failing to act on climate change and urges prompt global action on both encouragement and adaptation. Adaptation to change already occurring is essential in the poorest developing countries, which will be hit earliest by climate change and which will be least able to cope. The review suggests that the impact of climate change may be mixed with temperature rise possibly by reduction in the heating effect of the Gulf Stream. The review would have been more comprehensive if there was a level of quantitative analysis and assessments on the cost minimization graph. An important message in the report is the need for adaptation measures to cope with the climate change already occurring, especially in the poor countries. Stern says that sensible decisions are required and the planet deserves the benefit of the doubt to promote growth and development.
