I agree with your reply. As long as the amount of stored carbon by the forest increases, it is a valid form of carbon sequestration, and, IMHO, the most beautiful.

Regarding other methods, people should Google for: norway carbon sequestration. Note: The volumes are very limited -- not enough to burn coal as your primary energy source, then capture all the CO2 and pump it underground.

To be clear, I am not shilling for non-forest/peat based carbon sequestration. To me, it is mostly a green washing game by big oil, gas, and utility firms to delay action and avoid responsibility.
