Mitigation of Climate Change. The Summary for Policymakers concludes that there was a high level of agreement and much evidence that ‘there is substantial economic potential for the mitigation of global greenhouse gas emissions over the coming decades, that could offset the projected growth of global emissions or reduce emissions below current levels’, [30] taking into account financial and social costs and benefits. Responding to climate change 4. This projection was not included in the final summary for policymakers.

IPCC reports cover the “scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation.

Inter-relationships between adaptation and mitigation] Schneider ”et al. Archived from the original PDF on 10 September Over the six years studied, the actual temperature rise was near the top end of the range given by IPCC’s projection, and the actual sea level rise was above the top of the range of the IPCC projection.

According to Sheldon Ungar’s comparison with global warming, the actors in the ozone depletion case had a better understanding of scientific ignorance and uncertainties. The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more. This page was last edited on 1 Juneat Network of African Science Academies.
