01 — THE RECORD
Every tree keeps a diary of the climate it grew in. We're asking it, one ring at a time, how much warmer the diary can get before the pages stop turning.
We believe trees are honest narrators of climate. Every ring, every scar, every missed year of growth is a number — and the number only moves in one direction.
