If we split our atmosphere today into 1 million parts, 421 of them would be made of carbon dioxide. And while 421 parts per million (ppm) might not seem like a lot, it’s the most we’ve seen in at least 3 million years. All of this extra carbon dioxide is warming up the planet.
These levels have sped up during your lifetime, but don’t take it personally: that fact is true for everyone alive today. But you know what else can happen in your lifetime? We can take the most important steps to reduce carbon emissions and give our planet the future that is least impacted.
It will take collective action. It will take new technologies. And it will take very old technology—like nature.
