Now this may seem rather simple but please follow these numbers and tell me where I'm wrong...
Carbon sequestration, air quality, and climate change
- A tree can absorb as much as 48 pounds of carbon dioxide per year, and can sequester one ton of carbon dioxide by the time it reaches 40 years old.
- One large tree can provide a supply of oxygen for two people.

In 2011, utility coal plants in the United States emitted a total of 1.7 billion tons of CO2.
A typical coal plant generates 3.5 million tons of CO2 per year.

According to the last forest inventory, there are almost 247 billion trees over 1 inch in diameter in the U.S. Tree Facts Facts About Trees
So according to my figures... 40,800,000 trees can absorb ALL the 1.7 billion tons of CO2 emitted each year by all the coal fired utility plants.
That means 0.01% of all the TREES in USA are absorbing the 1.7 billion tons of CO2 emitted each year.
What is wrong with these figures then?
I'm not even going to respond to the stats as far as the numbers are concerned. I'll merely respond to the claim of trees as a carbon sequestration destination.
To paraphrase your OP, please follow along. Carbon-based fuel (in the form of coal and oil) has been sequestered and buried underground for millions of years. At best, a tree might be expected to hold on to the carbon for a couple of hundred years before it dies (and decays) or burns in a natural fire, or is cut down (and is burned or decays) thereby releasing the CO2 back into the air.
Consequently, trees are not much of a carbon sink, all things being equal. That's especially true considering that the carbon is being taken out of a proven secure sink (until humans get to it) and placed in a temporary location. It's like taking your money out of an underground vault and placing it in a coffee can buried in your back yard. It damn sure isn't safer there.
What is your expertise that you can spout without ANY substantiation?
I at least am giving you the sources of where I came up with the numbers... where's your sources?
I've read several books on global warming for one thing. But what I just said is obvious once people stop to think about it because it's a mathematical truth that many people haven't really thought through when they think of planting trees as a sequestration solution.
Simply put, once you take carbon out of the ground where it's been for millions of years (and would likely continue to be for millions more years if we left it there), that carbon dioxide is reintroduced into the evironment (the air). One tree is not going to take that CO2 molecule out of the atmosphere for any longer than the tree lives. If trees lived millions of years, than it would be a wash. But trees don't live for millions of years, do they? What that means is that once that particular variety of tree approaches its statistical end of life based on its general longevity (lifespan), ANOTHER tree will have to be planted to take up that same carbon. The same process would have to be repeated over and over again by subsequent generations just for the CO2 released today.
But realistically, on a planet with a growing human population which needs more and more arable land for growing food, how many trees can be planted to take up all the CO2 we are creating now, and tomorrow, and next year, only to need to continue to plant even more trees to replace the ones that die (or that we cut down)?
But the trend is just the opposite, isn't it? More and more old growth forests are being cut down, and it takes one HELL of a lot of saplings to make up for all the carbon in a 200 year old tree.
