& yet nither of you have said how we would stop the stored co2 from re-entering the enviroment.

Laugh

That's because if you decompose it it won't be CO2 anymore, it'll be Carbon and Oxygen, silly!

Yes, Carbon dioxide is comprised of one carbon and two oxygen atoms, but In its solid state, it is commonly known as dry ice.

However my point was / is.

Co2 is stored in trees ......... cut down tree .....tree rots, co2 released.

Co2 is stored in tree ...... tree burns in bush fire .......... co2 released.

Co2is stored in trees ......... tree cut down & turned into furniture .... furniture rots or burned,
& Co2 released.

Ice caps.

Co2 which is millions of years old is stored in the ice caps as tiny gas bubbles in the ice,

& if the Ice caps melt.

Carbon dioxide - Oceans

The Earth's oceans contain a huge amount of carbon dioxide in the form of bicarbonate and carbonate ions—much more than the amount in the atmosphere. The bicarbonate is produced in reactions between rock, water, and carbon dioxide. One example is the dissolution of calcium carbonate:

CaCO3 + CO2 + H2O ⇌ Ca2+ + 2 HCO3-

Reactions like this tend to buffer changes in atmospheric CO2. Reactions between carbon dioxide and non-carbonate rocks also add bicarbonate to the seas, which can later undergo the reverse of the above reaction to form carbonate rocks, releasing half of the bicarbonate as CO2. Over hundreds of millions of years this has produced huge quantities of carbonate rocks. If all the carbonate rocks in the earth's crust were to be converted back into carbon dioxide, the resulting carbon dioxide would weigh 40 times as much as the rest of the atmosphere.

The vast majority of CO2 added to the atmosphere will eventually be absorbed by the oceans and become bicarbonate ion, but the process takes on the order of a hundred years because most seawater rarely comes near the surface.

Since 1996 a Norwegian Oil Company Statoil , has been engaged in an experiment to test the feasibility of reservoir storage, pumping CO2 into a water-bearing sandstone layer known as the Utsira formation beneath its giant Sleipner gas fields. In this deep saline aquifer the CO2 becomes absorbed into the water within two or three years in the same way that CO2 dissolves in mineral water. It is hoped that localised chemical reactions will also cause some of the CO2 to form carbonates and bicarbonates that would remain stable for millennia. The Utsira formation currently holds four million tonnes of CO2 and there is plenty of room for more. Estimates suggest that the sandstone, which is capped by an impermeable shale layer, could hold three years worth of CO2 emissions from all the power stations in Europe put together. It is a cost effective exercise for Statoil too, for by storing the CO2 in this way they are saving themselves Norway’s hefty $38 a tonne carbon tax. They expect to recoup their $80 million investment within two years.

The idea of using old oil wells has also been extended to old coal seams. The idea is that the CO2 would become trapped by absorption onto the surface of the coal.

In 1986, 80 million cubic metres of volcanically derived CO2 gas dissolved in the bottom waters of Lake Nyos in Cameroon vented to the surface and asphyxiated 17,000 residents and countless livestock. The accidental dissociation of potentially huge amounts of industrial CO2-hydrate stored on the sea bed is probably only a matter of time and statistics and the consequences unimaginable.

'
I know, and under normal pressure it doesn't go to liquid phase between solid and gas.

But I didn't say solidify it, that's not a good solution. I said decompose it.

What do you propose we do about CO2 released in forest fires? Or by the oceans? What are we supposed to do about that? We're talking about reducing the CO2 we emit, not that created in nature.

I don't see a good reason to decompose it, I see it as a raw material source for nanotube building materials and other carbon composites. The key being dual use.

You want Carbon for carbon nanotubes, not carbon dioxide, right?

If that's correct then you do want to decompose the CO2 so you're left with no CO2, only carbon and oxygen.

Sorry I misread your statement earlier. I mistook it as decomposing carbon not CO2 which didn't make sense to me. I assumed we already got to seperation in this thread, and saw nothing wrong with storing the carbon by itself. so I mixed up my bad.

That's what I was thinking happened. 🙂

The co2 in trees is by no means natural.

Do you really think trees can tell the different between co2 that was created by a cow farting & the co2 created from the billions of car on our hi ways.

it does not work like that.

90% of the carbon in trees, is still man made.

& well are making more co2 each & every day in ever new ways.

1) an increase in the amount of man made co2.

2) less places to store it.

When a tree burns in a forest fire, or a wooden table rots .......... a paper book or newspaper breaks down & decays, any & all co2 that was stored in the product5, (tree, wood, paper) is released fr4om storage & re-enters the atmosphere, where it will do further damage.

& lets not forget that the co2 in the ice caps will also be re-released into the atmosphere as the ice melts, an the co2 bubbles in the ice escape.

Old stored co2 being added to the already high current levels of co2 = speeding up of the entire climate change process.

Show me your sources.
Oh, you've got none.

Do you really think that matters?

Retort.
Where is your scientific study that refutes my statements of fact.

Counter retort.
