#Frontier just announced the second round of #carbon #dioxide #removal (#CDR) purchases by #Stripe and #Shopify. One of the companies is Captura, which is supposedly doing "Direct Ocean Capture."

Removing CO₂ from seawater is not CDR (you have to wait until that seawater equilibrates with atmospheric CO₂) so I don't know how this is better than Ocean #Alkalinity Enhancement.

But I don't care. I want to see them build this thing exactly as it's rendered here.

It's hard for people to visualize removing tons or billions of tons of #carbon #dioxide (CO₂). I propose we talked 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.
