How does an increase in global temperature affect human health? (Select all that apply)
Hotter temperatures increase the death rate of people with heart problems because their body must work harder to keep itself cool. The prevalence of certain diseases depends on local climate. An increase in warm areas allows tropical diseases to spread. Hotter temperatures exacerbate air pollution issues, such as higher ozone concentrations at ground level, increasing respiratory disease rates.

Europe
Which of the following statements are true regarding the impacts of the Kyoto Protocol? (Select all that apply.)
Europe met the goal of reducing their greenhouse gas emissions below their 1990 levels by 2012. Developing countries were exempt from signing it, so most did not have goals to meet and continued to increase their greenhouse gas emissions.
