Could global warming actually be good for the forests?
The researchers speculate that increased temperatures could have lengthened the trees' growing season, or that climate change-related fog reduction is allowing them to get more sunlight. But it's also possible that a reduction in air pollution from wood processing plants, or the human effort to suppress wildfires, is spurring the growth instead.
The only thing they can really conclude from this is that climate change doesn't appear to be actively harming the forests. That's still much better news than anything else we've been hearing lately.
