It is believed that the Anasazi (a native American tribe) suffered some kind of “change” in climate, political upheaval [due to a change in climate that everyone protested?], drought [is this not a change in climate?], that caused them to abandon their settlement and migrate elsewhere. In the 1300s! Is this not evidence of “climate change” that could not have been caused by fossil fuels? Or do the alarmists believe that Anasazi campfires started the whole global warming era?
