Magnesite
Unless we have a major life threatening release of co2, like from super volcanoes or the bottom of the ocean, last thing we need is scientists trying to change the atmosphere.
Correct me if I’m wrong, but don’t plants and trees need CO2 to live? And don’t they emit O2 which, by the way, humans and animals need to live?
I think these climate change/global warming hoaxters better ger reigned in soon or dire consequences may result.
Didn’t nature already create something to take CO2 out of the air? I think they are called plants such as trees.
So if CO2 is a problem then we need more trees. The bonus is we get oxygen from the process. Win win. Problem solved
Trees do a good job of that now. Zero cost. No maintenance required.
So now the alarmists want to intentionally monkey with the environment, something we barely understand, in order to save us from something they clearly don’t understand, but say they do.
The only solution enviro-whackos want is the destruction of capitalism. It’s not about global warming, it’s always been about a political agenda.
Researchers Find Rapid Way to Make Carbon Dioxide-Storing Mineral Magnesite making vegetation massively recede and atmospheric oxygen drop. Oxygen Futures will be the next Big Thing.
A Fable:
During the time of the Dinosaurs, the Earth’s atmospheric level was much, much higher, but the climate was also much warmer. So being ardently against climate change, Dinosaur researchers removed CO2 on a massive scale; everywhere vegetation died back and oxygen levels plummeted making the planet uninhabitable for Dino Kind. But, despite the set back, they all felt good to their last breath for having stopped climate change.
Free lunch? I don't think so.
In a few short years, legal marijuana plantation will be sufficient to do this.
Oh sure but will it alter cyclical global wind patterns and solar activity? Nyet.
Remember that volcanic explosion 2009 in Iceland that sent a huge plume of smoke and ash into Europe shutting down air traffic for a day or two?
Mother Nature the biggest polluter of them all. Oh the doomsday fears of LIEberals.
This is great, we need this for steel making

Magnesium is the eighth-most-abundant element in the Earth’s crust by mass and tied in seventh place with iron in molarity.[6] It is found in large deposits of magnesite, dolomite, and other minerals, and in mineral waters, where magnesium ion is soluble.
Although magnesium is found in more than 60 minerals, only dolomite, magnesite, brucite, carnallite, talc, and olivine are of commercial importance.
The Mg2+
cation is the second-most-abundant cation in seawater, which makes seawater and sea salt attractive commercial sources for Mg. To extract the magnesium, calcium hydroxide is added to seawater to form magnesium hydroxide precipitate.

Magnesium hydroxide (brucite) is insoluble in water and can be filtered out and reacted with hydrochloric acid to produced concentrated magnesium chloride.

From magnesium chloride, electrolysis produces magnesium.
https://en.wikipedia.org/wiki/Magnesium#Occurrence
Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert.
Magnesite is also present within the regolith above ultramafic rocks as a secondary carbonate within soil and subsoil, where it is deposited as a consequence of dissolution of magnesium-bearing minerals by carbon dioxide in groundwaters.
Formation
Magnesite can be formed via talc carbonate metasomatism of peridotite and other ultramafic rocks. Magnesite is formed via carbonation of olivine in the presence of water and carbon dioxide at elevated temperatures and high pressures typical of the greenschist facies.
Magnesite can also be formed via the carbonation of magnesium serpentine (lizardite) via the following reaction:
2 Mg3Si2O5(OH)4 + 3 CO2; Mg3Si4O10(OH)2 + 3 MgCO3 + 3 H2O.
However, when performing this reaction in the laboratory, the trihydrated form of magnesium carbonate (nesquehonite) will form at room temperature.[6] This very observation led to the postulation of a “dehydration barrier” being involved in the low-temperature formation of anhydrous magnesium carbonate.[7] Laboratory experiments with formamide, a liquid resembling water, have shown how no such dehydration barrier can be involved. The fundamental difficulty to nucleate anhydrous magnesium carbonate remains when using this non-aqueous solution. Not cation dehydration, but rather the spatial configuration of carbonate anions creates the barrier in the low-temperature nucleation of magnesite.[8]
Magnesite has been found in modern sediments, caves and soils. Its low-temperature (around 40 °C [104 °F]) formation is known to require alternations between precipitation and dissolution intervals.[9][10]
Magnesite in a natural form (from Lubeník in Slovakia)
Magnesite was detected in meteorite ALH84001 and on planet Mars itself. Magnesite was identified on Mars using infra-red spectroscopy from satellite orbit.[11] Controversy still exists over the temperature of formation of this magnesite. Low-temperature formation has been suggested for the magnesite from the Mars derived ALH84001 meteorite.[12][13] The low-temperature formation of magnesite might well be of significance toward large-scale carbon sequestration.[14]
Magnesium-rich olivine (forsterite) favors production of magnesite from peridotite. Iron-rich olivine (fayalite) favors production of magnetite-magnesite-silica compositions.
Magnesite can also be formed by way of metasomatism in skarn deposits, in dolomitic limestones, associated with wollastonite, periclase, and talc.
Uses:
Dyed and polished magnesite beads
Magnesite of Salem
Similar to the production of lime, magnesite can be burned in the presence of charcoal to produce MgO, which, in the form of a mineral, is known as periclase. Large quantities of magnesite are burnt to make magnesium oxide: an important refractory material used as a lining in blast furnaces, kilns and incinerators. Calcination temperatures determine the reactivity of resulting oxide products and the classifications of light burnt and dead burnt refer to the surface area and resulting reactivity of the product, typically as determined by an industry metric of the iodine number.
‘Light burnt’ product generally refers to calcination commencing at 450 °C and proceeding to an upper limit of 900 °C - which results in good surface area and reactivity. Above 900 °C, the material loses its reactive crystalline structure and reverts to the chemically inert ‘dead-burnt’ product- which is preferred for use in refractory materials such as furnace linings.
Magnesite can also be used as a binder in flooring material (magnesite screed).[15] Furthermore, it is being used as a catalyst and filler in the production of synthetic rubber and in the preparation of magnesium chemicals and fertilizers.
In fire assay, magnesite cupels can be used for cupellation as the magnesite cupel will resist the high temperatures involved.
Magnesite can be cut, drilled, and polished to form beads that are used in jewelry-making. Magnesite beads can be dyed into a broad spectrum of bold colors, including a light blue color that mimics the appearance of turquoise.
Research is proceeding to evaluate the practicality of sequestering the greenhouse gas carbon dioxide in magnesite on a large scale[16].
Occupational safety and health
People can be exposed to magnesite in the workplace by inhaling it, skin contact, and eye contact.
USA
The Occupational Safety and Health Administration (OSHA) has set the legal limit (permissible exposure limit) for magnesite exposure in the workplace as 15 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 10 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday.[17]
Why are these fools wanting to steal our planet’s plant food?
Okay libs, decision time.
Do you want trees and plants or do you want to starve the vegetation by storing its food in a bunch of rocks.
You’re choice. Can’t have both.
Settled science :)

Magnesite is Magnesium oxide.
Where does CO2 come into this?
CO2 is the molecule of life.
The more CO2 we have, the more abundant life becomes.
This is what the freaks are fighting: LIFE!
