Geoengineering The Ocean — What Might Presumably Go Improper?

Assist CleanTechnica’s work by means of a Substack subscription or on Stripe.

It’s modern at present to lambaste scientists as a bunch of nattering nabobs chasing analysis {dollars} to allow them to write boring reviews nobody will learn. Science is a rip-off, some say, a deliberate try and clog the wheels of progress with scary prognostications that don’t have any relevance to the principle objective in life — earning profits.

These individuals who put private achieve forward of science dismiss the concept the Earth is getting hotter as the results of human exercise. Doesn’t it say within the Bible that God gave people dominion over the Earth? Doesn’t that imply something people do has the blessing of the Creator? And if one thing, someway, does have a unfavourable impact on the surroundings, why, we’ll merely engineer our method out of the scenario so we will carry on doing what God put us on Earth to do — generate income.

Engineering The Ocean

Lots of these geoengineering options contain tinkering with the ocean, which absorbs numerous the carbon dioxide within the environment. However that creates an issue. These of you who took chemistry in highschool know that when carbon dioxide dissolves in ocean water, it turns that water acidic. Sure, it’s a weak acid, however creatures that stay within the ocean have tailored over hundreds of thousands of years to seawater that’s much less acidic.

The rise in acidity primarily results crustaceans — animals that use the calcium present in ocean water to make the shells that shield them from predators. Beneath is a photograph of a shell positioned in acidic water and the way the acid impacts it over a interval of 45 days.

Adapt Or Die

Rex Tillerson, the bozo who was once the CEO of Exxon, appreciated to snarl that folks would simply need to adapt to modifications within the surroundings. Rex was very rich however had no frequent sense. He didn’t perceive that the variations he was speaking about take tens and even a whole bunch of hundreds of years to happen. The modifications that he so blithely claims people have to adapt to happen over just a few a long time — an infinitesimally quick time frame in geological phrases.

A few of the variations embrace extra cooling for properties and buildings, or — as Jimmy Carter as soon as urged — placing on a sweater. The issue for whales, dolphins, coral, lobsters, and photoplankton is that they can not simply flip the thermostat up or down — or placed on a sweater. They’re helpless to have an effect on the temperature, salinity, or acidity of the watery world they stay in. If they can not adapt as a result of the modifications occur too quickly, they die.

So what? Allow them to die. Who cares about sea creatures? Douglas Adams, writer of The Hitchhiker’s Information To The Galaxyas soon as mentioned, “People suppose they’re smarter than dolphins as a result of we construct automobiles and buildings and begin wars and so on., and all that dolphins do is swim within the water, eat fish and mess around. Dolphins consider that they’re smarter for precisely the identical causes.”

A Geoengineering Examine

In a research printed January 14, 2026, within the journal Advancing Earth And House Sciencesa global group of researchers examined all present geoengineering proposal to evaluate what their influence on the ocean could be.

These methods embrace photosynthesis enhancement, iron fertilization, or seaweed cultivation. “A fraction of the carbon they seize throughout development could be saved within the ocean for a whole bunch of years, however a lot of it leaks again to the environment as soon as biomass decomposes,” the researchers declare.

Rising crops on land and sinking them in deep, low-oxygen waters the place decomposition is slower can delay the discharge of the carbon contained in them — a course of often known as anoxic storage of terrestrial biomass.

Ocean alkalinity enhancement chemically converts carbon dioxide in seawater into different types of carbon, permitting the ocean to soak up extra from the environment. This works by including giant quantities of alkaline materials, resembling pulverized carbonate or silicate rocks like limestone or basalt, or electro-chemically manufactured compounds like sodium hydroxide.

Then there are the strategies extra generally often known as geoengineering — mechanically altering the environment to mirror a portion of the daylight that strikes the Earth day by day again into house. “The enchantment of photo voltaic radiation modification is velocity: It might cool the planet inside years, however it will solely quickly masks the results of still-rising carbon dioxide concentrations,” the researchers level out.

Dangers And Rewards

Each technique has dangers and rewardsthey declare. Including extra carbon dioxide to the ocean makes the water extra acidic. Including alkaline supplies, resembling pulverized carbonate or silicate rocks, might counteract the acidity of the extra carbon dioxide by changing it into much less dangerous types of carbon.

“Organic strategies, in contrast, seize carbon in dwelling biomass, resembling crops and algae, however launch it once more as carbon dioxide when the biomass breaks down — which means their impact on acidification relies on the place the biomass grows and the place it later decomposes.”

However there are dangers. “Fertilizing the floor in a single space could increase plant and algae productiveness, however on the similar time suffocate the waters beneath it or disrupt fisheries hundreds of miles away by depleting vitamins that ocean currents would in any other case transport to productive fishing areas.

“Ocean alkalinity enhancement doesn’t require including vitamins, however some mineral types of alkalinity, like basalts, introduce vitamins resembling iron and silicate that may influence development. Photo voltaic radiation modification provides no vitamins however might shift circulation patterns that transfer vitamins round.

“Shifts in acidification and vitamins will profit some phytoplankton and drawback others. The ensuing modifications within the mixture of phytoplankton matter: If totally different predators favor totally different phytoplankton, the follow-on results might journey all the best way up the meals chain, ultimately impacting the fisheries hundreds of thousands of individuals depend on.”

Effectively, that’s actually meals for thought, isn’t it?

The Least Disruptive Methods

“Of all of the strategies we reviewed, we discovered that electrochemical ocean alkalinity enhancement had the bottom direct threat to the ocean, nevertheless it isn’t risk-free. Electrochemical strategies use an electrical present to separate salt water into an alkaline stream and an acidic stream. This generates a chemically easy type of alkalinity with restricted results on biology, nevertheless it additionally requires neutralizing or disposing of the acid safely.

“Different comparatively low-risk choices embrace including carbonate minerals to seawater, which might improve alkalinity with comparatively few contaminants, and sinking land crops in deep, low-oxygen environments for long-term carbon storage. Nonetheless, these approaches carry uncertainties and want additional research.”

We Dare To Disagree

Additional research? In a world that treats scientists as charlatans, when our leaders inform us sea ranges are falling not rising; that the Earth is getting cooler, not hotter; and that harvesting the power for the solar and wind is a best rip-off in human historical past? Towards that backdrop, the researchers argue for a cautious, evidence-based path ahead. Right here is their abstract, as introduced in The Dialog:

Some scientists have argued that the dangers of local weather intervention are too nice to even take into account and all associated analysis ought to cease as a result of it’s a harmful distraction from the necessity to scale back greenhouse fuel emissions.

We disagree.

Commercialization is already underway. Marine carbon dioxide elimination startups backed by buyers are already promoting carbon credit to firms resembling Stripe and British Airways. In the meantime, world emissions proceed to rise, and plenty of international locations, together with the U.S., are backing away from their emissions discount pledges.

Because the harms brought on by local weather change worsen, strain could construct for governments to deploy local weather interventions shortly and with out a clear understanding of dangers. Scientists have a chance to review these concepts fastidiously now, earlier than the planet reaches local weather instabilities that might push society to embrace untested interventions. That window received’t keep open perpetually.

Given the stakes, we consider the world wants clear analysis that may rule out dangerous choices, confirm promising ones, and cease if the impacts show unacceptable. It’s attainable that no local weather intervention will ever be secure sufficient to implement on a big scale. However we consider that call ought to be guided by proof — not market strain, concern, or ideology.

In different phrases, a scientific method is finest for the Earth and for humanity. What a novel idea!
