Ocean acidification is one of the concerns I feel we haven't discussed as much. I'm glad people are innovating new solutions to deal with this.

[@PlanetZero-ClimateChange]

They didn't really discuss this in the video, but olivine is actually a great pH buffer. Once dissolved in seawater, it will actively raise the pH beyond just through removal of CO2. It literally addresses two problems at the same time and doesn't introduce anything unnatural into the ocean. The amount that would need to be ground into powder for this to be feasible is pretty absurd though.

[@debbiehenri345]

Since CO2 causes acidification in our oceans, then locking it away by adding olivine, planting Mangroves (which you can actually do for free atm by going the Microsoft weather app, do a few simple game-like 'tasks' to grow a virtual tree, Microsoft then sponsoring the planting of a real Mangrove trees in Kenya), and farming seaweed/shellfish will actually de-acidify the oceans and help to normalise it again.

[@jyotirmoypoddersagor7933]

Farming in the ocean through the method of IMTA (Integrated Multi-trophic Aquaculture) can bring a feasible solution. It offers the scope of farming seaweed, fish, and shellfish at a time with less emission of carbon, and little use of fertilizer or pesticide.

[@philippanicker5618]

Brilliant. Much more simpler, and uses natural processes. No need to expend energy (and man power, and money and fuel and electricity and materials) to capture CO2 which the processes in this video require. And it brings economic returns, which helps create jobs and improve the livelihoods of people involved, which in turn creates a goodwill towards nature.

There’s another action that Americans can take immediately in order to help: call your senators and tell them to support the RISEE act.

That way, we can protect areas which are already operating as carbon sinks and even help them expand so they can take up even more carbon!

The sea organisms consume almost as much oxygen as it is produced there, we could not relay on that source. Every few seconds, we cut down a hectare of forest to grow crops so we can feed animals for meat, eggs and dairy. These forests are in fact, our main real source of oxygen and carbon sequestrators.

[@Kevin_Street]

I was skeptical when I saw your title, but those are all good ideas! Restoring coastal ecosystems like mangrove forests and sea grass is something we should be doing anyway, so that makes sense. I'm not sure that carbon sequestration is even the best reason for replanting, since the carbon is only sequestered while the ecosystem is there. If someone decides to build a resort and wipes out a mangrove swamp, the carbon that was in it will go right back into the atmosphere. The real reason for restoring these places is maintaining biological diversity and the greater ecosystem of the oceans as a whole. Real carbon sequestration should lock away the carbon dioxide for hundreds or thousands of years, so we can't unintentionally screw up and release it all again. That's what makes the flow reactor sound like a really good idea. It's a direct solution that sounds more tenable than other carbon capture methods I've heard, like burying dried algae. Unfortunately it shares the scale problem of other direct methods. There's just so much CO2 to remove, it will take a vast army of flow reactors running constantly to make even a dent in the problem. Could such a thing be financed through carbon credits? The best solution of the three, _if it works_ , is probably the olivine dumping. It directly removes the carbon by turning it into minerals, and it uses natural forces like the waves and sea creatures to magnify its effect for less cost than something like the flow reactor. It sounds like dumping a relatively small amount of olivine could have a large effect. Repeat that year after year and it might actually make a difference. And while it isn't innately profitable, if they keep combining it with beach restoration like they're doing now it should be possible to get people to pay for it. But all three of these are good ideas, and like they said in the video, _everything_ helps. The problem is too large for any one solution, so we need to do everything that makes any kind of sense.

Very informative as always. Could you please do a video on ocean fertilization? It's basically yeeting iron dust into the ocean which is used by algae/plankton as food which in turn pulls CO2 out of the atmosphere and sinks to the bottom of the ocean. It seems like such a simple solution which makes me wonder why we aren't doing it on a large scale. There have been German studies to it decades ago but I don't think they went anywhere.

[@Anncrohr]

Dumping huge amounts of anything is prohibited internationally by the London convention. That also includes iron of any sort for fertilization, so there had to be a change in laws first before even just experiments in moderate scale could be conducted and evaluated. If would have a huge impact on the fertilized ecosystems, so close monitoring would be crucial at first.

[@dalewalkonen7847]

Peter Fiekowsky's book, Climate Restoration, goes into this in detail. He describes what happens when it's done in the deep ocean - phytoplankton quickly increase and attract whales and other marine life. A lot of CO2 is sequestered! It has been successful.

[@gaia3520]

You have to make a video about Pleistocene Park. The amount of CO2 that could be captured+ the prophylaxis to prevent more CO2/methane from entering the atmosphere is enormous.

[@rajlal2384]

Hi PhD in air quality/climate change here and frequent commenter... Carbon capture will be a part of the climate change mitigation portfolio, but it shouldn't be the driving solution, particularly considering the technology isn't mature yet and it's not yet economical (as mentioned in the video). Targeting emissions should be the focus, which will have additional benefits including air pollution emission reductions. Targeting emissions will promote efficiency and thus cost savings

[@Zachry86]

@DWPlanetA We need a update on the Vesta / Olivine project!

[@PlanetZero-ClimateChange]

I'm a little upset that ocean iron fertilization was not mentioned in this video. If humanity is serious about avoiding the worst outcomes of climate change, we need to consider every idea for removing CO2 from the oceans. It has been experimentally proven (EIFEX) that carbon can be sequestered into the deep ocean by fertilizing surface waters with iron to promote the growth of plankton. This could be one of the most cost effective ways of removing CO2 from the air and oceans at a significant level.

[@vaibhavsharma1496]

Wouldn't this just make ocean acidification worse? I'm a marine ecologist and whenever I see solutions like these, I wonder if anyone thought about the consequences for nature... If the fake shells sink to the ocean floor, they'll dissolve (because they can't stay intact below the CCD), and then we've just got sped up ocean acidificatio, right? We should really start looking at lowering emissions properly, aggressively, and right now, instead of forcing nature to work overtime to even out our crap. If we throw the water chemistry off balance, we'll be harming all kinds of organisms from single-celled to giant. Anything with a shell would be directly affected by sped-up ocean acidification, but even organisms without a shell rely on the gradient (difference) between the outside and inside. If the outside isn't what they were made for, they have to work harder to keep their insides the way they need them to survive. This, like faking volcanic eruptions sounds like a very bad band-aid. AND irreversible. Once we mess this up, we can't undo it. PS: It took me a while to figure out that your video is beeping and not my house. Especially at 2x watch speed, that beep in the background is really annoying. (Sorry, fellow KZbinr here, so I thought you'd like to know)

It is going to take a large number of solutions to 'begin' to extract excess CO2 from our atmosphere and oceans. However, the biggest change must come from us - from reducing our need to constantly buy needless 'stuff' manufactured by those countries who simply don't care what they do to the planet, acting primarily to make lots of money in the cheapest ways possible. One thing about the Olivine...what are the CO2 emissions of mining, transporting and crushing this mineral in comparison to the amount of CO2 it finally extracts?

[@danielvonbose557]

Take a thorium reactor on the Columbia plateau as a primary energy source to grid basalt to provide a basic raw material, ground basalt, which has obvious uses. From there is can be transported by letting the Columbia River transport it as sediment to Puget sound where it enters the coastal environment to undergo the weathering process. It could also be used by agriculture to supply calcium, magnesium, and iron.
