We Must All Make Sacrifices To Stop Global Warming

From Quadrant Magazine, with apologies to Johnathan Swift's "A Modest Proposal" : The Aztec Solution:

Climate modelling of new data from the Aztec Codex Cihuacoatl has identified a relationship with important implications for global warming mitigation. The research suggests a strong causal pathway exists between climate change and Aztec rituals of “nourishing the gods” with blood sacrifice.

The evidence supports a revival of (humane) human sacrifice (HHS) as a mechanism for retarding environmental degradation and reducing dangerous climate change. HHS also would improve crop yields by allowing more effective control of surface temperature and rainfall; create anthropogenic biochar for soil enhancement and long-term carbon enrichment, especially in tropical environments with low-carbon sequestration capacity and depleted ferrasol and acrisol zones; and reduce population growth rates as the Earth’s carrying capacity comes under further pressure this century....

At least... I hope it's tongue-in-cheek.
