Earlier quoted context omitted.

Such as? Unless the tree gets subducted or interred (aka turned to Coal or similar), it’s still part of the cycle, and its carbon will still eventually return to the atmosphere. And with the evolution of lignin eating fungi (white rot fungi being particularly efficient) many millions of years ago, good luck with that. Capacitors are useful, but they aren’t sinks.

ok, so far.. there appear to be at least two angles.. One is the factual measure of the role of carbon in various forests over time; the second is as a target for collective action. Deforestation and forest fire are certainly significant sources of carbon emissions. Not all carbon goes into the atmosphere, however. Given current conditions and human practices, acting now to prevent deforestation and catastrophic fore…

None of that contradicts what I’m saying on any meaningful timescales. You’re literally quoting 1-2 decades. That is short term.

And frankly, it’s obvious. Carbon in any form takes up space. If a forest continually sequestered carbon in solid form (in excess of its wood content, which is easy to measure and plateaus VERY quickly!), every forest that was more than a couple decades old would be sitting on top of a layer of carbon hundreds or thousands of feet deep. It would have to be.

Even the healthiest forests are lucky to have a dozen feet of soil with meaningful carbon content, and most of them it’s a couple feet.

There is nowhere else for that carbon to go except the atmosphere.

And eventually - in hundred, or a few cases a thousand or so years - all those trees die due to climate changes or fires, and they’re gone. Back into the atmosphere.

Somewhat related: A natural disaster when a lake released a giant burp of CO2: https://en.wikipedia.org/wiki/Lake_Nyos_disaster

I'd just like to say that I've spent a good portion of day telling everyone who I think will be interested about this.

Thanks for sharing!

I wonder how practical it would be to add something smelly and distinctive to CO2 the way we do with natural gas? Otherwise a CO2 leak is really mysterious. It could be in quite low concentrations, to the point where you would only smell it if the air was getting to dangerous levels. This wouldn't help with a release from a natural source, but if we are ramping up carbon capture efforts maybe we'll see more industria…

Difficult if used for beverages. In my experience CO2 may not have an odor but at high concentrations it burns the hell out of your nostrils anyway.
