1. Survival Period of Mankind on Earth

Global total CO₂ emission and sequestration are being analysed from 1960 to 2029 reports interpreted from DEP, DOE, IPCC, CFC, CDIAC, IEA, UNEP, NOAA and NASA. Consequently, these reports have been transcribed into each 10 years period data set by using MATLAB software to accurately calculate the decadal emission and sequestration rate of total CO₂ within the world. Then these data were further analysed to determine the final annual increasing rate (Yr⁻¹) of CO₂ accumulation into the atmosphere. The study revealed that total CO₂ emissions throughout the world since the 1960s have been increasing rapidly, and the recent year the net CO₂ increasing rate is 2.11% annually. If the current annual CO₂ growth rate is not copped now, the atmospheric CO₂ accumulation shall indeed reach at a toxic level of 1200 ppm concentration into the atmosphere in 53 years. Consequently, the entire human race will die due to the severe breathing problems due to the toxic level of CO₂ presence in the air and that would be the time for the end of human civilization on Earth.
