On Friday's broadcast of HBO's "Real Time," host Bill Maher reacted to this week's Intergovernmental Panel on Climate Change report by stating that he thinks an environmental "disaster is coming" and that "the world is coming to an end." But noted that there is a tendency to give very specific predictions on when environmental calamity will happen, "and some of those dates have already passed." And argued that people should stop doing this because it destroys their credibility and is "like what the western medical establishment found out about COVID, don't lie about it."
