Mona Charen: “If Democrats got their fondest wishes regarding climate change, the U.S. would spend billions more on solar, wind and other energy sources that are more expensive than hydrocarbons and incapable of meeting our energy needs. We would simultaneously delay or impede the development of cheap and environment-friendly natural gas, and tax and extensively regulate industries that produce or rely on fossil fuels. The result would be slower economic growth and more hardship. … The Democrats’ doomsday predictions are phantasms spun of speculation, worst-case assumptions and panic aimed at increasing the government’s control of economic life. The Republicans’ doomsday fears are based on the arithmetic certainty that we cannot pay the estimated $86 trillion in debt we’ve amassed.”
