Today's education demands that every health professional is properly educated about the mechanisms by which climate change places our existence and well-being at risk. Public health professionals must be especially knowledgeable about the health dangers of climate change, who is most vulnerable and how they are vulnerable. Doctors, nurses, pharmacists, administrators and public health leaders must be educated to understand the nature of the approaching or recurring environmental challenges associated with climate change. They need to shape the response of the sizable U.S. health sector(s) so that individuals and their communities, including their hospitals, clinics, and pharmacies are prepared for and protected from the menacing effects of climate change and have effective responses when anticipated events do occur. Climate Change and Population Health begins by explaining the global warming and climate change by looking back historically, reviewing current measurement techniques and results, and taking into consideration greenhouse gases and their origins. It then looks at the health impact as well as who is most effected by climate change, before guiding students on how to effectively communicate about climate change as a means of helping people to protect themselves. Finally, it discusses possible policy solutions that might be beneficial to help mitigate health issues caused by climate change.
