"Climate Change 2007 - The Physical Science Basis" is the most comprehensive and up-to-date scientific assessment of past, present and future climate change.

This paper discusses the possibilities and constraints for adaptation to climate change in urban areas in low and middle-income nations. These contain a third of the world's population and a large proportion of the people and economic activities most at risk from sea-level rise and from the heatwaves, storms and floods whose frequency and/or intensity climate change is likely to increase.

Sea level rise (SLR) due to climate change is a serious global threat. The scientific evidence is now overwhelming. Continued growth of greenhouse gas emissions and associated global warming could well promote SLR of 1m-3m in this century, and unexpectedly rapid breakup of the Greenland and West Antarctic ice sheets might produce a 5m SLR. In this paper, the authors have assessed the consequences of continued SLR for 84 developing countries.
