Measuring the history of CO2 in our atmosphere

Measuring the history of CO2 in our atmosphere

This graph, from the WMO Statement on the State of the Global Climate in 2017, shows the history of CO2 concentrations in the atmosphere. Since 1958, we’ve measured CO2 directly. To measure CO2 prior to that, we use “proxies”; that is, measurements...

The slinky of rising CO2 and temperatures

This video is a new animation showing CO₂ concentration and global mean temperature 1958 to the present, by Kevin Pluck. He sourced the data from NOAA and NASA. “CO2 is just steadily growing and growing and growing. It’s so consistent and so frightening.” —...
The Great Wave of CO2

The Great Wave of CO2

Every year, the planet breathes CO2 in and out. The exhale starts in late fall and continues until about early May, when the inhale begins and continues to late fall. This correlates to the growth and decay of plant matter in the northern hemisphere (where much of the...
CO2 since the Cubs last won the World Series

CO2 since the Cubs last won the World Series

Congrats to the Cubs, but is there a correlation between lack of winning and CO2 emissions? Likely not, but you never know! This is a funny, yet totally not funny graph. It shows that the CO2 concentration in our atmosphere has risen by over 100ppm since the Cubs last...
