Last week, the world passed a milestone: the amount of carbon dioxide in the atmosphere passed 400 parts per million. This is the most we’ve had in the atmosphere in all of human history, and it’s more than the planet has seen in several million years.
But 400 ppm is just a number, right? What does it mean? Let’s paint a picture, shall we?
- Last time there was this much C02 in the atmosphere, sea levels were 60-80 feet higher. Take a moment to imagine that.

Last time we had this much C02 in the atmosphere, the world was 8°C hotter than it is right now. This temperature is extinction level for humans because food is nearly impossible to grow, fresh water is scarce, most of the world’s species will go extinct, and oceans turn to acid and die. German people make horror dramas about worlds this hot.
If any of this scares you, welcome to my world, as the saying goes. If you’re scared, that’s a good thing, it means you understand the scale of the problem and are having a natural human response. By no means is our situation hopeless…this problem has a solution. But nothing’s going to happen unless you take that terrible feeling in the pit of your stomach and do something with it.
















The Greatest Speech Ever Made
The years ahead will test men’s souls. As climate change takes root and we reach the limits of economic growth, we will feel stress and may think to take from others to maintain ourselves. But this is not our true nature, and it is not the way things need be. Our actions are merely products of our social constructs and values, things which we ourselves created, things we can change any time we like.
Here, Charlie Chaplin reminds us of this. I think I’ve got something in my eye…
