We used to cut more old growth, now not so much.  How does that affect CO₂ sequestration?

Why did we have more acreage burning in the 1930s?

Drawdown emphasizes Tropical Forests rather than Boreal Forests in the discussion of carbon sequestration. Why is this?

More and more Canadian Geese seem to be spending the full year at the southern end of their migratory pathway. Scientists suggest it’s because of domestication.  This doesn’t sound right.
