Millennia from now, if there’s one piece of data that humans alive today will be known for, I think it would be this. Carbon Dioxide Levels over the Past 10,000 Years Image modified from the Keeling Curve This graph shows us the historical record of carbon dioxide levels in Earth’s air, over the last 10,000 years. For most of this time, carbon dioxide levels were quite stable — that’s the relatively flat portion of the graph. Agriculture, cities and civilizations all got their start somewhere along those gentle slopes. This stability coincided with the moderate climate following the last ice age, which ended around 15 thousand years ago.
