Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.

Most of Earth's carbon—about 65,500 billion metric tons—is stored in rocks. The rest is in the ocean, atmosphere, plants, soil, and fossil fuels. Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components.

I don’t think you understand soil.
No I think you're right, I kind of assumed that the carbon in the soil would be taken up, with whatever its bound too, as material for whatever is grown. But I've been wrong before.
“No I think you're right”
It happens.
Sometimes.
Obviously there are people who understand soil a lot, but I’m sure they don’t think they understand it all.
More importantly there is a general lack of public understanding, not helped by the idea that it is ’dirty’.
In farming, as an industry, there are those who see it mostly as a medium for containing commercial chemicals.
A standing forest - particularly a boreal one - is a standing carbon sink for as long as it stands. Trees fall and decay and are replaced so the forest abides, man.
Peat builds up and is quite stable over tens of thousands of years.
The ultimate removal mechanism is in the carbonate shells of molluscs which wind up as limestone over geological time scales. That's released by subduction into an active volcano.
As the concentration of carbon dioxide rises the pH of water in contact with it drops. Quite quickly you get to the point where mollusc shells aren't stable and can't be laid down. That's one of the tipping points that might end human life. There are quite a few others.
“A standing forest - particularly boreal ones - is a standing carbon sink for as long as it stands.“
Yes, but for the next 10-50 years it’s perhaps more about what sorts of trees and planting/management will result in greatest carbon capture in shortest time.
“A standing forest - particularly boreal ones - is a standing carbon sink for as long as it stands. Trees fall and decay and are replaced so the forest abides, man.“
As long as the forest doesn't find itself on the wrong side of a planning application for the latest new town.
This is the bit that bothers me about carbon credits and the various offset schemes sold, airlines are particularly bad for it. If I buy my way out of my carbon usage for my holiday to Maliga what guarantees are there that 50 years from now that carbon sequestered won't be released any way, either by not replacing fallen trees or having the forest clear cut for timber/housing/biofuel etc.
Carbon credits and offset are a scam. Similar schemes have operated for years.

More recently came high-end tourism workers catering for “last chance to see” cruises through the disappearing Arctic ice. Now, a growing body of academics and diplomats are here to examine how Svalbard and its people adapt to living on the frontier of climate breakdown.
Nowhere on the planet is heating faster. This was the message of a report commissioned by the Norwegian Environment Agency, unveiled in February to a stunned audience in Longyearbyen, the archipelago’s de facto capital. People knew things were bad, but it was only when they heard the forecast that they realised how bad. A local reporter described how people at the meeting fell silent when they heard the statistics, which sounded like the “gloomy horror scenario of a bad thriller”.

Friederike Otto, at the University of Oxford, UK, one of the scientists behind the new analysis, said: “This is a strong reminder again that climate change is happening here and now. It is not a problem for our kids only.”

I think they are failing to grasp several points, but no doubt they know they can still fool some of the people some of the time.

Planting billions of trees across the world is by far the biggest and cheapest way to tackle the climate crisis, according to scientists, who have made the first calculation of how many more trees could be planted without encroaching on crop land or urban areas.
“
I think an immediate planning presumption against tree felling would also be a step in the right direction, in addition to the massive tree planting programme that is certain to start any day now.

Research published last week said planting billions of trees across the world was the biggest and cheapest way to tackle the climate crisis.
But some in Ireland have a problem with the great green vision. They say Ireland is planting the wrong sort of forests – dark, dank abominations that kill wildlife, block sunlight and isolate communities.

Until now, most of the focus of work on the climate crisis has been on “mitigation” – jargon for cutting greenhouse gas emissions, and not to be confused with mitigating the effects of the climate crisis. The question of adapting to its effects has taken a distant second place, in part because activists and scientists were concerned for years that people would gain a false complacency that we need not cut emissions as we could adapt to the effects instead, and also because while cutting emissions could be clearly measured, the question of adapting or increasing resilience was harder to pin down.

This basically restates what iwrats said above.

Don’t entirely understand that article.
Seems to be only talking about a trees to wood products purpose/cycle.
Presume the current plan to plant mega numbers is for for most of them to remain as trees.
There is the idea that they will just decay to CO2.
But surely that’s where coal came from (plant life generally) and the current problem is (partly) related to burning this.
Similarly oil - not trees, but humans deliberately releasing the CO2.
I’m sure there are those (not on CCE of course) who imagine a technology fix (CCS or similar) - plus a few trees - will neutralise current CO2 releases, and maybe a bit extra.
But I think a LOT of trees could make a reasonable amount of difference.
PLUS a serious reduction in current/future fossil fuel use is still required.
There are those who think Nuclear could be a significant help, but conventional economics is largely against this and, I suspect, eco-economics even more so.
