An international team of scientists have found a potentially viable way to remove anthropogenic (caused or influenced by humans) carbon dioxide emissions from the atmosphere -- turn it into rock.
The study, published in Science, has shown for the first time that the greenhouse gas carbon dioxide (CO2) can be permanently and rapidly locked away from the atmosphere, by injecting it into volcanic bedrock. The CO2 reacts with the surrounding rock, forming environmentally benign minerals.
Measures to tackle the problem of increasing greenhouse gas emissions and resultant climate change are numerous. One approach is Carbon Capture and Storage (CCS), where CO2 is physically removed from the atmosphere and trapped underground. Geoengineers have long explored the possibility of sealing CO2 gas in voids underground, such as in abandoned oil and gas reservoirs, but these are susceptible to leakage. So attention has now turned to the mineralisation of carbon to permanently dispose of CO2.
Until now it was thought that this process would take several hundreds to thousands of years and is therefore not a practical option. But the current study -- led by Columbia University, University of Iceland, University of Toulouse and Reykjavik Energy -- has demonstrated that it can take as little as two years.

I still doubt that our contribution to atmospheric CO2 means much.
All plants require Carbon dioxide in order to survive. If they do enough of this, they’ll kill off the plants.
And they’re just dumb and corrupt enough to do it. No doubt they’ll get huge government grants.
Our contribution is around 0.0002% of the total. This is a one of those ideas that will have unintended consequences - its not nice to mess with Mother Nature - she needs the CO2 for her plants and to give us more oxygen, which, by the way, has been steadily declining for millenniums.
Climate change is a hoax. All efforts to “mitigate the damage” of CO2 “pollution” (aka plant food) is a waste of resources.
Carbon dioxide in the atmosphere is absolutely essential for photosynthesis. Getting all “wee weed up” (you will remember the erudite scholar who coined that term) over it makes about as much sense as pushing a boulder uphill—fruitless and senseless.
Watch these religion of the left evil wizards, put us into an ice age. So much better than Gorebull wurming.
It must hurt these Luddites to learn that Science and Technology might eventually come to their rescure..
wizards, put us into an ice age. So much better than Gorebull wurming.
It's a win-win for everybody.
Satellite survey has revealed a greening of the world, especially the more arid regions. The higher the CO2, the less stomata the leafy component require for transpiration, leading to less water loss through the leaves.

If co2 in the atmosphere is reduced to half of what it is now, all life will cease to exist. On the other hand co2 can increase 150 TIMES before it is toxic.
I think we should turn all that excess carbon dioxide into pianos. Everybody likes pianos, they add value, and you can use lots and lots of wood thus sequestering all that nasty carbon. Makes more sense than rocks.
This sounds like the quack docs that used to go around selling remedies that could cure every ailment known to man last century in old wagons They even use scientific terminology and speak in a confident manner like they know what they’re talking about - just like the charlatan quack docs did. Bet things haven’t changed that much; just the outfits they wear.
“All plants require carbon dioxide. I if they do enough of this, they’ll kill off the plants.”
There are three different types of carbon dioxide; the co2 created by evil companies, and the co2 that humans give off, along with all the other ways that co2 is produced.
There should be a government program to label all molecules as evil or benign depending on where they came from. All co2 molecules should be traced from origin, then labelled as good or bad. The bad c02 should be destroyed and the good c02 labelled for plant consumption only.
See? Ya know?

IMHO
This statement seems to want to make the reader think that there is a difference between CO2 emitted by nature and CO2 emitted by humans. It is the same molecule. CO2 = CO2. This process, or any other, can't tell the difference.
Furthermore, there already are natural process that take carbon dioxide out of the atmosphere and turn it into rock.
Carbon dioxide from the air dissolves into the water of the ocean. Animals which create seashells take dissolved carbon dioxide in the ocean and combine it with Calcium, creating calcium carbonate seashells. After the organism dies, the shell sinks to the bottom of the ocean. Sometimes there are enough shells that compressed sedimentary rock, limestone and chalk, are formed. The chalk of the "White Cliffs of Dover" were created this way.
This actually isn't a good thing. Once the limestone is made, nothing in nature puts the carbon dioxide back into the atmosphere. The Earth used to have a lot more carbon dioxide in the atmosphere than it does now, but it has been sequestered into limestone. In about 11 millioin years, the carbon dioxide in the atmosphere will be used up, and life on Earth will be extinguished.
This solution fails to create a global government or a global tax therefore it’s not a solution.
I read it that the plant would take production related CO2 (human industrially produced) and pump it into igneous rock. That might reduce your reasonable objections.
For “carbon sequestration”, why don’t we just landfill plastic instead of recycling?
Suggest that to a liberal and watch their head explode.
Please see my post # 17. There would be a reduction of industrial CO2 which wouldn’t impact nature. We remove many things (i.e. Sulfur, Arsnic) from industrial emissions.
