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

70,000 tons "to date" is a heck of a lot less than 37 billion tons annually. It would take over 500,000 identical facilities with no environmental impact to reach net zero.

Yes, now we're tolkien.

lol fuck what a company thinks, what can they prove

A reasonably well-known climate scientist.

[-] Umbrias@beehaw.org 1 points 11 months ago

Okay...

Will be interesting to see peer reviews of their work.

Don't know about the specifics in the OP but I believe it's a similar process to this:

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

[-] Track_Shovel@slrpnk.net 2 points 11 months ago

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.

Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
