Did you know there’s about 400 parts per million (ppm) of caffeine in coffee? There's over 400 ppm of CO₂ in our atmosphere today. If you've felt the surge of caffeine hitting your system, you've experienced the effects of just 400 ppm.
Graphic looks down on a cup of coffee, with Planet Earth as the “coffee.” To the right of the coffee cup is the text “Can you tell the difference between caffeinated coffee and decaf?” Below the coffee cup is the text “If so, you have detected a concentration of 400 parts per million (ppm). There’s more than 400 ppm of carbon dioxide in Earth’s atmosphere.” It follows with bold text saying “Small amounts of powerful substances have big effects.”
