Columbia Climate School: New York City’s Hidden Old-Growth Forests
Columbia Climate School: New York City’s Hidden Old-Growth Forests. “Historic preservation has never been New York’s strong point; about 1,000 old buildings are demolished or gut-renovated every year, the remains mostly going to landfills. Now, a team from the Tree Ring Laboratory at Columbia University’s Lamont-Doherty Earth Observatory is harnessing the destruction to systematically mine torn-out timbers for data. Annual growth rings from trees that were young in the 1500s may offer records of past climate no longer available from living trees. Studies of timber species, ages and provenances can shed light on the history of U.S. logging, commerce and transport.
