It's better to reduce emissions than to try and capture a couple of 0.0X% of CO2 in the atmosphere. That's obvious to everyone and so everyone agrees and that gets upvoted.

In reality, good luck having cows and steel (=iron+carbon) and cement on this planet without GHG emissions. Even plane fuel (long-distance flights) is basically going to have to do carbon capture to make 'electrofuels' (or biofuels) that they then burn and put back into the atmosphere, at least with how it's currently looking.

It saddens me to see that people are rambling, and others are voting it to be the current top comment, about teratons (a unit even I hadn't heard being thrown around before) which is of course a ridiculous notion. The point of this technology is to neutralize unavoidable emissions in thirty-odd years. We can't, in thirty years, start to develop this tech and hope it works the next week.

It also allows us to put a direct price point on CO2. You pick: remove CO2 or don't emit it. A smart company will choose the cheaper option. Only a few years ago, planting trees or "preventing emissions" magic accounting was considered offsetting. This sets a new standard.

So long as it's within proportion, I really see no downsides to funding the development of this tech. The roll-out to megaton or gigaton scales, yeah we should see about that when we actually have renewable energy to spare, not when the gas, nay, coal plants are still in full operation. But for now, we're struggling to reach a few dozen kilotons economically, and that's why this is necessary work and good news.

The problem is that the price on this will be severely underestimated. Every year we hear our estimates of climate damage are underestimated.

Then the wildfires around the world and in the arctic started becoming to frequent to ignore.

The real problem is that the extraction industries will fight tooth & nail to not have subsidies much less additional cost - and they have won and continue to win to this day.

How can the price be underestimated if we can pay commercial providers to build more of those plants? At minimum, it will be the cost price of doing this work, which (at some minimum) is hard to argue about.

I guess you mean the underestimated impact, i.e. "cost" to society (insofar as human lives have a € value), if we don't do anything? Because that's a different discussion. I presume that lawmakers would be in agreement that we need to curb emissions, otherwise it's an entirely different conversation to be having (and flashbacks from 10-20 years ago).

Well said. Saw in your bio that you're working on capturing carbon dioxide, can you share more?
Thank you. Sadly that's poorly phrased on my part. The bio says that I'm "into" that tech; i.e. it interests me. All I'm doing to capture CO2 at the moment is pay Climeworks monthly. I also took a sneak peek at their Orca plant in Iceland when I was there, but not much to see from the outside aside from a big 'keep out' sign.

I asked them if there would be any sort of tour available, given that the neighboring power plant has an exhibition (which is superb by the way! Easily worth the money, and I spent quite a bit of time geeking out there on.is/en/geothermal-exhibition/). Initially Climeworks responded, we exchanged a few emails, and one of their marketing guys wanted to give me a call, so I sent my number and... got ghosted. No replies to reminder/follow-up emails or anything. Bit bummed but oh well, didn't expect there would be anything available in the first place so I can't complain.

As for the other climate-related part of my bio, reducing emissions, there's a whole host of things but mostly things everyone already knows is an option: I chose to live in a place where I can commute by public transport, I buy and sell second hand instead of new when possible, reduce meat consumption (prioritized by a CO2/kg chart, which unfortunately includes cheese above chicken iirc) and buy veggie/vegan food to vote with my wallet, vote green in elections since imo basically everything else (short of war-like situations) can wait a few years, etc.

Well better than nothing! If you have plans to return to Iceland, maybe I can point you to someone helpful on their team. my email is my username @ airminers.org.

And if you do get curious about working on carbon removal, check out the AirMiners Boot Up: https://bootup.airminers.org/

Thanks for the pointer! Definitely checking that out. And thanks for the offer, though Iceland was expensive and required... yup... a flight, so I might not be going back too soon to Iceland specifically. Beautiful place though.

I also love how this picture on your website about sums up this discussion about how to solve the climate problem: https://images.squarespace-cdn.com/content/v1/602c4ede5fdbd7...

memes will save the climate!
Wouldn't be HN without letting perfect be the enemy of good. Kind of a given due to the sort of person it takes to be interested in hanging out here (passionate about tech, somewhat cynical etc :p).
