On January 27 , 2024, the world population was 8,087,421,644 according to the most recent UN estimates. Without further action to limit population growth, they estimate there will be 8.6 billion people in 2030, 9.8 billion in 2050, and 11.2 billion in 2100. With roughly 83 million people being added to the world’s population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline. In the spring of 2023 the population of India surpassed that of China while the U.S. remained a distance third where it is projected to remain until 2050 when Nigeria will move into third place.
Carbon emissions increase significantly with every additional person on earth — the rich more than the poor — and increases the number of climate change victims – the poor more than the rich.
There is clearly a direct correlation between population and climate change.
