Government tells us that we must all believe in the climate prophesies and repent of our carbon sins, or a great flood, hell fire, famine and pestilence shall come. These are easy concepts to push, because every religion uses them to control their followers.
This is exactly the sort of flagrant abuse which the First Amendment was written to protect us from.
Amendment I. Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
