A study published in the current issue of Science finds that big, old-growth trees worldwide are dying off at a frightening rate. Everywhere the researchers looked — Yosemite, the Brazilian rainforest, Europe, the far Northern latitudes — the biggest and oldest trees were in stark decline.
“It’s a worldwide problem and appears to be happening in most types of forest,” one of the lead authors says.
The study itself is behind Science’s paywall, but numerous news outlets are running stories about it. See: The New York Times, The Week, the CBC, Science Daily.
