Both the developed as the developing world will be affected. The developing world is expected to be affected to a greater extent though. Some effects are:
* changing weatherpatterns (greater or fewer precipitation on specific areas, the weather is also expected to be much more radical). This will negatively affect [[farming]]<ref>www.knmi.nl/africa_scenarios/brochure_Afrika.pdf</ref><ref>http://earthobservatory.nasa.gov/Features/Water/images/precipitation_intensity_map.png Precipitation changes</ref><ref>http://climatelab.org/@api/deki/files/462/=Desertification_map.png</ref>
* natural disasters. These are expected to rise. Death toll in 2003 = 150000 people <ref>[http://www.wired.com/science/discoveries/news/2003/12/61562 150000 people killed by global warming upto 2003]</ref><ref>http://climatelab.org/climate_change_security</ref>
* Sea-level rise<ref>Sea level rise: 2m rise expected by 2100 A.D., 6,5m by 2200 A.D.</ref> will contaminate a very large percentage of the agricultural fields with sea salt and make them no longer suitable for continued food production.<ref>Earth under water documentary</ref> In addition, many low-lying islands and coastlines will need to be abandoned, forcing many people to move.
