Fertilizing oceans with iron that can and will strip the Earth's atmosphere free of carbon dioxide will be terrible for plant life for plants needs carbon dioxide to breath in in order to live AND PRODUCE FOODS AND MEDICINES for us!

There is another way that iron can be used to sequester carbon in the ocean. Mineral deposition through electrolysis has the ability to quickly store tones of carbon through the formation of calcium carbonate. This process can and already has been used to repair damaged reefs or create entirely new ones. Not only does this store carbon quickly, it promotes the growth of marine ecosystems that store even more carbon. Furthermore, the creation of marine ecosystems increases much needed fisheries that are needed to help feed a growing population.

Solar and wind are garbage. Nuclear is the only viable solution. Yes, solar/wind produce more waste. The Fukushima Exclusion zone is less radioactive than Denver. Even at the worst case scenario for Chernobyl nuclear is a factor of 10 times safer than solar and a factor of 100,000 times safer than coal. Entire us solar capacity = 2 GW nuclear plant. most of this energy is provided when it is not needed which artificially deflates the price of solar. Adding nuclear to the grid increases supply 24 hrs a day reducing price across the board. Economies that rely on solar/wind suffer from having coal/nat gas plants which struggle to profit, during times when solar/wind are off (literally every single day at some point every day) people end up paying ridiculous amounts for electricity. Solar produces 300 times more waste than nuclear and panels have a half life of 30 years. A solid nuclear plant can last 80 years. Cost per GW in China,South Korea, and France is 3 billion and dropping, this is easily achievable or we can contract France to build for us. The time for the nuclear age is now. bitch ass solar and wind do nothing but cause problems and delay the solution. What to do with waste? up your ass. No seriously, steel barrels. It's solid material, it won't fly off. Nuclear when it goes wrong is better than solar when it goes wrong is better than coal when it goes right.

So if lower temperatures leads to desertification on land but more iron/phytoplankton in water, does that basically mean that less photosynthesis on land leads to more in the ocean, and vice-versa?

[@sDesa1]

For the people who say that this will damage the environment if people go through with this: True, having too much iron in one place can create devastating algae blooms IF fishes and other sea life can't consume enough of it quickly, or the phytoplankton consuming too much oxygen, creating a dead zone. However, spreading iron dust in controlled amounts in a wide area means that fishes can thrive with the increase of food, which means there will be bigger quantities of fish, which can feed both us, and important predators such as sharks to help them keep the populations in check. And because of the increase of fish, corals and seagrass can be fertilized with fish urine. This leads to coral reefs and kelp forests to regrow, ontop of millions of scientists and conservationists seeding new kelp forests and supporting coral reefs.

[@jasonmatthewson8534]

I have a theory... I don’t think as much iron would be needed as you stated was calculated. Phytoplankton are a key 1st step in the marine food chain. If you could build an ecosystem with kelp, fish & other marine life where you intend to put the iron. It would become self sustaining ecosystem as the fish eat the plankton, they deposit fertiliser (poo) on the kelp (which also helps convert CO2 to O2), I believe the kelp naturally draws up iron from the bed. Then when bits of the the kelp decompose, they will break down further helping the phytoplankton in a positive feedback loop. The scientists just need to carefully select the plants fish & organisms to create the positive feedback ecosystem.

We know that iron dumping into waters not in those two areas also works. Specifically Russ George's dump into the Pacific Northwest created a bloom and a subsequent record harvest of fish.

As we also know from Russ George's experiment, the government actually won't let you do this.

[@christopheb9221]

If we only need a trace amount there should be ore that doesn't need to be processed. Then we should filter and collect these booms and put them in emptied hydrocarbons/ fossil fuel wells. Or turn this into a factory process powered by renewable energy. Grow algae, plankton, cyanobacteria whatever collects the most carbon. Then some way separate and concentrate the collected carbon and if possible using least amount of energy, turn that carbon into the densest carbon compound/molecule (meaning most carbon atoms possible in given area. I'd assume co2 isn't even compressed) and put that in the emptied oil and gas wells

One consequence that you didn't mention is what happens when you suddenly increase the abundance of primary producers in an unsustainable way. 10 times as many phytoplankton leads to 10 times as many zooplankton, then 10 times as many small fish, and so on down the line. When you stop inputting iron, suddenly you have 1/10th the amount of phytoplankton and still 10 times as many organisms on the upper trophic levels, this would be absolutely devastating to the ecosystem.

[@steevesdd]

You reference that the effects of iron seeding are short lived. However they are immediate. So this could be away to reduce co2 levels now. So that additional warming could be reduced. With further research the process could be refined to create a more precise method to estimate co2 reductions. The method is cheap enough that it should be pursued to create a better model of what can and can not be done.

[@fuelcelltechsmith6307]

adding iron is just the first step, the problem cited was the earth's natural carbon sequestering rate. the various affects of this iron seeding is that by giving the base producers a population boom, the rest of the ecosystem follows suite. which opens up many diverse ways of exploitation, exploitation of this artificial boom would take the carbon out via fishing and or algae farming and we can stop the usual carbon decomposition process artificially though whatever happens to be profitable

Iron would also oxidise and thus take vital oxygen out of the water which would adversely affect the ecosystem. That is where the iron ore came from in the first place. The first photosynthisisers produced oxygen which oxidised the free iron in the sea and deposited as banded ironstone. It was only when the excess iron was removed from the sea that oxygen could build up and encourage the evolution of complex life. Also you mention nitrogen is essential for life, but so is carbon. Every living thing is packed with it and most produce co2 as a byproduct. The miracle is that animals produce co2 but green plants produce an excess of oxygen by absorbing co2 so the system is self balancing ultimately. We need plants for oxygen and they need us to produce co2.

If it gets warmer, sure. Warmer temps means longer growing seasons, more food. Every previous warming period had a population boom among humans (and life in general). We're still colder than about 800 years ago, at least in the Northern Hemisphere. If the planet gets colder, then populations will shrink as food production drops and disease becomes more prevalent. Warmer is generally better, for most forms of plant and animal life.

U.S. and Canadian gov shut him down though, due to concerns about near-shore algal blooms, but that relatively small experiment seemed to work exactly as expected. It's hard sell for governments as you are technically polluting the oceans with industrial waste, even though by that logic all fertilizer used on land is doing the same thing. Russ George believes we could sequester nearly all of the world's carbon emissions at an expense of only a few million dollars per year, while also increasing the world's fish harvest to the degree that everyone in the world would be able to afford to eat wild-caught seafood daily.

Huh, interesting. I get alarm bells when its suggested industrial waste can be spread on the oceans for "good". As stated "we don't know" l hope we do before we "tinker with the planet". It's a fine balance and a process that occurs in long cycles. I would like to point out the planet has been warming for over 10,000 years with temp spikes + - far beyond anything in the present day.

I suggest buying wood deep underground or under the ocean as a solution.

[@Spright91]

Maybe this idea is terrible but that doesn't mean we shouldn't study it and other geoengineering ideas. Because we might find out that one of them is actually a really good solution.

Why use refined iron? The stuff in dust certainly is iron oxide. That would be a lot less energy intensive to get, as you skip the whole refining process.

Another awesome video pnce again.

Why is it iron deficient in the first place? Anyway, it's a breakthrough in our understanding, and I guess a fundamental point in marine farming. Adding iron will increase plankton to feed farmed fishes.

Didn't someone try this to replenish salmon stocks on the west coast in BC? If I remember it correctly it failed spectacularly and ended up really messing things out for the aquatic ecosystems in the area.

Really educational

I'd like to hear more debunking, I'm still on the fence. If I was in charge of stuff I'd run more tests.

How might a increase in primary production effect fish stocks?

Let's take old cars/scrap steel and clean them and dump them out in the ocean. Old cars also make good habitats for coral

The only realistic possibility to fully stop anthropogenic climate change, is to use space based mirrors/solar arrrays, either in earth orbit or even better at the LZ1 point between earth and sun, with super heavy lift launch vehicles like Starsip, which will bring down cost immensely, the cost for such a project could be below 100 billion, those sattelites can be controlled, so if we see some negative unexpected impacts, we can modulate/turn off the system imidiatly, we could also selectivly shade certin areas more, for example the poles or equator. Investing into this will be cheaper by orders of magnitude, than the consequences of climate change, potenially save the homes of billions of people from destruction/inhability and save over a million species from going extinct.

Carbonization is not just a problem for humans, as it reduces the overall diversity of life on earth because it is a relatively sudden change. It Is unclear whether this will be catastrophic, but reversions to prior states generate stresses to existing life forms.

If dusty winds do the job of adding trace amounts of iron to the oceans then I don't think we'd need to refine iron to enrich the oceans. Iron rich dust would be just as good though far bulkier to transport. Rivers currently dump nutrients into the oceans. So this iron laced dust could be added to Delta areas of the rivers as they flow out to sea. The atmosphere could be seeded with iron dust using thermals (columns of air used by eagles) and atmospheric jet streams to distribute the iron dust for free. The geodesic cages could be seeded with iron bearing rocks/dust to increase plankton productivity. Given that ships are the cheapest form of transport seeding iron rich dust shouldn't be so costly. If the waters are cold enough the algal organic matter sinking to the lower levels will not decompose and thus sequester the carbon
