There is broad consensus within the scientific community that the climate is changing and that humans have probably contributed to this in the form of an increase in carbon emissions. The Intergovernmental Panel on Climate Change's Fourth Assessment Report said there is ninety percent certainty that human activity was the primary cause of rising temperatures observed since 1950; if the climate increases by more than two degrees Celsius, scientists predict disastrous consequences for humans and the world (McMichael and Lindgren, 2011, p. 402). Climate change, however small, causes changes in other seemingly unrelated aspects of life. As current research suggests, climate change will have negative effects on human health and nutrition, increasing disease while negatively affecting the global food supply. Both of these effects will have negative implications on the quality of life of people around the world. Climate change is a global problem, therefore climate change policy should consider its health impacts, as climate change will ultimately affect the well-being of all people living on this planet . It is therefore everyone's responsibility to take measures that will help slow the rate of current global warming. The effects of climate change will impact human health to varying degrees around the world. One of the most direct impacts on human health will be the rate and incidence of infectious and non-infectious diseases. These disease states will affect humans in different ways. The Center for Disease Control (CDC) predicts that climate change will affect the incidence of vector-borne diseases and zoonoses through four main mechanisms: s...... middle of article...... h Impacts in developed countries.
