Mesofacts: slowly changing facts

An article from 2006 in the New Yorker by Richard Preston, entitled Tall for its Age (alas, behind a paywall) chronicles the recent discoveries of the world's tallest trees. These trees, with colorful names like the Stratosphere Giant and Helios, are all Redwoods and about 370 feet tall. The tallest is named Hyperion and is over 379 feet tall, and was only discovered in the last few years.
