Climate change is a serious ongoing problem for mankind. The 4th International Panel on Climate Change (IPCC) report in 2007 stated “Warming of the climate system is unequivocal”, and “observational evidence from all continents…that many natural systems are affected by regional climate change”. Global warming affects hydrological and terrestrial biological systems including alteration in rainfall, air pollutants, bird migration, arthropod species, plants, and so forth.
Climate change brings a lot of impacts on human health, through direct exposures such as the extreme heat and cold waves or indirect exposures such as change in water, air quality, vector ecology, agriculture, etc. In August 2003, a heat wave in France caused more than 14,800 deaths. Extreme cold temperature in Europe from December 2009 to January 2010 caused about 100 deaths. Children in low-income countries suffered from increased diarrheal diseases which were found to be associated with high temperature (Checkley et al., 2004; Singh et al., 2001). Vector-borne diseases such as Dengue fever, malaria are influenced by climate change. In the fact sheets in January 2010, WHO also states ”climate change affect the fundamental requirement for health – clean air, safe drinking water, sufficient food and secure shelter”.
