Roy Spencer explains that The Killer That Matters Most to Africans is not global warming:
What is killing Africans in greatest numbers is poverty, and international trade policies that prevent Africans from protecting themselves from diseases that are easily preventable. The Ambassador mentioned pressure from environmentalists in wealthy nations that has prevented the construction of hydroelectric dams in Africa, denying electricity to millions of people. Two billion of the Earth’s inhabitants still do not have access to electricity, leading to massive death tolls from problems such as food-borne illnesses (due to a lack of refrigeration) and pneumonia brought on by breathing air contaminated by the burning of dung or wood for heat and cooking. Anyone that has had to suffer through a loss of electricity for any length of time becomes quickly aware of how necessary electricity is for daily life.
