It was estimated by the  United Nations  to have  exceeded 8 billion  (8,000,000,000) on November 15, 2022. It took around 300,000 years of human  prehistory  and  history  for the human population to reach a billion and only 218 more years from there to reach 8 billion.

The problem is testing these hypotheses. I have developed a WBC Model (see below) for the variables Population ( N ), Production ( Q ) and Global Temperature ( T ) using available data and a number of assumptions.
