To put this in perspective, human population reached 1 billion in 1804, 2 billion in 1927, 3 billion in 1960 and 4 billion in 1974. The UN projects there will be 9 billion by 2037, and then (hopefully) stop increasing at around 10 billion in the 2080s (data per Population Connection’s white paper). The planet’s human population has doubled since many of us first became aware of the existential threat of global warming due to excessive emissions of carbon dioxide from burning fossil fuels. In the early 1800s, carbon dioxide emissions were relatively small. But by 1950, the world’s carbon dioxide emissions totaled around 6 billion tons per year. By 1990, this had almost quadrupled, reaching more than 22 billion tons per year. Now, emissions are over 34 billion tons each year, according to Our World In Data.
