Can rocks absorb enough CO2 to fight climate change? These companies think so
Can rocks absorb enough CO2 to fight climate change? These companies think so
Alphabet, Stripe, Shopify and other companies inked a first-of-its-kind deal.
I feel like there's a lot of these carbon-sequestration companies that are selling absolute poppycock and getting billions in funding, and very little actual oversight. They're doing this song and dance with "carbon credits", and eventually someone's going to peek behind the curtain and blow their cover.
I haven't seen one carbon-sequestration entity yet, besides those that are focused around planting trees, that have actually shown any real results other than vague handwavey bullshit. Like the ones saying they're capturing it out of the air and pumping it underground -- awfully convenient that nobody can fucking verify that it's actually happening eh?
It is a difference between scammers with certificate trading bullshit or science guys who try to make a business case of what science got us.
In carbfix its the latter.
Compared to others which are selling co2 certificates for forests which do not exist.
So what's carbfix's business model? How do they make money doing this? Can YOU, as an individual, verify what their claims are?
Not that I back this in any way but just what I've read: https://www.carbfix.com/proven
lol fuck what a company thinks, what can they prove
Don't know about the specifics in the OP but I believe it's a similar process to this:
The amount of CO2 & methane that needs to be removed from the atmosphere, now, to undo 5-9C of inevitable planetary heating...
Evolution of global temperature over the past two million years https://www.nature.com/articles/nature19798
Factoring in the excess methane, only ( not including other greenhouse gasses ), that we're producing, brings it up to 8-9C planetary heating, using methane's 20y CO2 equivalent, & 1.3 to 1.4ppm atmospheric methane added by us.
... is measured in the billions or trillions of tonnes.
I'm beginning to think that all the "we can ride this" idocy should be considered a categorical psychiatric delusion.

It's definitely billions of tonnes; that's the scale of yearly CO2 emissions
There's a thing in Iceland that binds CO2 underground.
It's pretty cool: https://www.carbfix.com/
Here's the science behind it https://www.carbfix.com/scientific-papers
Most locations aren't like that; they're injecting into oil and gas deposits with the risk of subsequent leakage
Enhanced rock weathering is very cool if it can be made to work at scale. Most examples have issues with needing a lot of energy to mine and pulverize rocks
They are looking at using Tailings storage facilities in mining for this reason
I
with the risk of subsequent leakage
That risk is like telling:" humanity will go down due to a eruption of a super vulcano"
But i agree carbfix is no solution for global scales.
