How 300 years of urbanization and farming transformed the planet

Long before power plants and cars began spewing massive amounts of carbon dioxide into the atmosphere, humans were having a massive effect on the Earth’s climate. It was farming, not factories, that lay behind this earlier anthropogenic transformation of the planet. I visualized this change over 300 years using estimates from a team of scientists, and added context to the data through science and history. (CityLab, 01/09/2019)
