NIPCC IR1 - Chapter 9 - Human Health Effects

August 29, 2011

Chapter 9 finds global warming is more likely to improve rather than harm human health because rising temperatures lead to a greater reduction in winter deaths than the increase they cause in summer deaths. The result is a large net decrease in human mortality. Climate plays a relatively small role in the spread of viral and vector-borne diseases, which suggests that continued warming would not increase the incidence of diseases. Higher atmospheric CO2 concentrations tend to increase the production of plant nutrients with direct medicinal value, such as antioxidants that protect cells from the damaging effects of oxidation.
