This is a sample data set, cobbled from various sources, about carbon dioxide emissions in the history of the planet from 800,000 BCE to the most recently concluded calendar year. I use this for a data visualization example for a lecture on climate change and international politics. Data communicate yearly averages/estimates.

co2emissions

Format

A data frame with 3,099 observations on the following 2 variables.

year

the year (negative values = BCE)

value

estimated carbon dioxide emissions (in ppm)

Details

The data come from many sources. Before 0 CE, the data come from 10 sources described here by the EPA (https://www.epa.gov/climate-indicators/climate-change-indicators-atmospheric-concentrations-greenhouse-gases). Observations from 0 CE to 2014 come from Meinshausen et al. (2017) (https://gmd.copernicus.org/articles/10/2057/2017/). Observations from 2015 forward come from NASA (https://climate.nasa.gov/vital-signs/carbon-dioxide/).
