Exploring Hydrocarbon Depletion
ROCKMAN wrote:KJ - "and sequester carbon even faster? " And that's the problem I have with the woodburner logic of the carbon cycle. Yes: burn a tree and eventually that carbon will again be sequestered. But the problem is the "eventually" part. Cut and burn one 20 year old tree this winter and that carbon will end up in another tree...in 20 years. Burn another 20 year old tree next winter and then wait 21 years for the total recycling of both trees. But in just 2 years you've injected 40 tree-years of CO2 into the atmosphere and sucked only 2 tree-years into existing trees.
IOW until you can grow a 20 year tree in just one year you continue creating a huge sequestration deficit.

but the last couple of years are closer to 3ppm per year ......the trend seems to be worsening

And unfortunately it is an upward curve. And getting steeper in spite of news that global emissions may have peaked.
