It's hard for people to visualize removing tons or billions of tons of carbon dioxide (CO₂). I propose we talk about CO₂ removal (#CDR) like a time machine (e.g., this machine will take us back 5 minutes). For example:

Q: How far back in time does planting 100 million trees take us?

A: If one mature tree takes up an average of 25 kg of CO₂ per year, then 100 million trees will take up 2.5 MtCO₂. That's a time machine that takes us back 33 minutes and 6 seconds in a year. It's not a lot.
