It’s gonna get hot: Atmospheric carbon dioxide over the past 800,000 years

There are lots of graphs related to climate change. Only a few, however, get to the core of the issue. This is one such graph. It shows atmospheric carbon dioxide (CO2) levels over the past 800,000 years—a period four times longer than our species, Homo sapiens, has walked the Earth. The units, parts per million (ppm), will not be familiar to everyone. But the units aren’t important.
