Carbon Sequestration: Trees won’t suffice.

Sequestering the amount of carbon we emit in trees would require truly enormous new forests. Planting mixed forests sequesters carbon at the rate over which the trees mature — so in 10–80 years after planting (depending on the type of tree), the tree must continue to live to hold carbon, but it does not offset new emissions Smil, 82.

• Offsetting just 10% of 2005 carbon would require a planting as big as the combined forests of North America and Russia, or a ~15% increase in tropical forests Smil, 82.

• Sequestration of forests fluctuates to the extent that some years forests can produce more carbon than they sequester Smil, 80

• Tropical forests' carbon impacts will change in the near future mostly due to deforestation, but many other forests will be limited by water and soil nutrient availability esp by nitrogen. We will also have more carbon releasing wildfires due to longer droughts from global warming Smil, 82
