At last, consensus: The Aztecs, the Mayans, and Time Magazine all agree that humans must make sacrifices to avoid droughts

Drought Cripples the South: Why the 'Creeping Disaster' Could Get a Whole Lot Worse - TIME

The Southwest in particular has a history over the past two millennia of mega-droughts that lasted for decades. Deeper into the geologic past, dust bowls endured for centuries. Just as worrying, climate change is expected to further dry out much of the region, potentially multiplying the impact of population growth and the usual dry spells. What the South is facing may not be just a drought, but the first signs of a permanent dry, one to which we'll need to adapt.

Like the global warming religion, the Aztec religion also believed that sacrifices were necessary to stop droughts

The Aztecs didn’t always practice human sacrifice. Sometime around 1450, the growing Aztec empire was experiencing severe drought that lasted for four years and destroyed their valuable corn crops. The Aztec priests encouraged the people to sacrifice blood to the gods to regain their favor. In desperation, the Aztecs sacrificed thousands of people in a few weeks. By awful coincidence the rain came and restored the corn crops. With this powerful evidence, what do you think the Aztec leaders learned? Soon the practice of human sacrifice became a necessary ritual to maintain the lifestyle they built.

The Mayans too

The famous Sacred Cenote (a natural well) located at Chichen-Itza was found to contain numerous skeletons of men, women and children who were sacrificial victims. Bishop de Landa, in the sixteenth century reported: "Into this well they have the custom of throwing Men alive as a sacrifice to the gods in times of drought, and they believed they did not die though they never saw them."
