There is broad consensus in the scientific community that the climate is changing and has likely received contributions from humans in the form of increased carbon emissions. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change stated that there is ninety percent certainty that human activity has been the primary cause of observed temperature increases since 1950; if the climate were to increase by more than two degrees Celsius, scientists predict disastrous consequences for humans and the world (McMichael and Lindgren, 2011, p. 402). Climate change, no matter how small, brings with it 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 states and having a negative effect on global food supplies. Both of these effects will have negative implications on the quality of life of people living around the world. Climate change is a global issue, so climate change policy should consider the health impacts it brings, as climate change will ultimately affect the well-being of everyone living on this planet. It is therefore the responsibility of every individual to take measures that help slow the rate of global warming currently underway. 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 both 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 and zoonotic diseases through four main mechanisms: s...... middle of paper ......h Impacts in developed countries.
