Watts Up With That?

peanuts_treemometerFrom the “trees aren’t linear instruments and the Liebigs Law department” and the Smithsonian Tropical Research Institute, comes this story that suggests the older trees are, the less linear their tree ring growth might be, which has implications for “paleoclimatology” and Mann’s hockey stick temperature reconstructions from tree rings.

Trees grow faster and store more carbon as they age

Trees put on weight faster and faster as they grow older, according to a new study in the journal Nature. The finding that most trees’ growth accelerates as they age suggests that large, old trees may play an unexpectedly dynamic role in removing carbon from the atmosphere.

Richard Condit, staff scientist at the Smithsonian Tropical Research Institute, devised the analysis to interpret measurements from more than 600,000 trees belonging to 403 species. “Rather than slowing down or ceasing growth and carbon uptake, as we previously assumed, most of…
