claim: When you account for the effects which are not reflected in the market price of fossil fuels, like air pollution and health impacts, the true cost of coal and other fossil fuels is higher than the cost of most renewable energy technologies.
evidence: Increases in atmospheric concentrations of CO 2 and other long-lived greenhouse gases such as methane, nitrous oxide and ozone have correspondingly strengthened their absorption and emission of infrared radiation, causing the rise in average global temperature since the mid-20th century.
