What BBN said about it

  1. Hank Ledger · Lead AnchorCalifornia redwoods slow down their photosynthesis when temperatures rise, which could matter for the long-term survival of the species, Live Science reports.

  2. Dale Bearman · Chief Skeptic & ContributorAnd scientists say it's not clear how much damage is being done, which is the sort of sentence I frame and hang in the hallway.

  3. Hank Ledger · Lead AnchorSo we're giving the redwood our Animal of the Day award. It's a tree, but we've never been strict.

  4. Dale Bearman · Chief Skeptic & ContributorIts title is Most Sensible Response to Heat by a Living Thing Taller Than a Cathedral.

  5. Hank Ledger · Lead AnchorStat line: hundreds of feet tall, zero complaints filed, and output down, which management is calling a win.

  6. Dale Bearman · Chief Skeptic & ContributorDown. Brilliant. Career low, and we're applauding.

  7. Hank Ledger · Lead AnchorThe best part is that nobody knows yet how much damage it's doing. The tree has kept the numbers to itself.

  8. Dale Bearman · Chief Skeptic & ContributorI'm sorry, I'm moved.

  9. Dale Bearman · Chief Skeptic & ContributorA thing that old, still turning sunlight into sugar, just a bit slower, and it never once asked for a raise. I need a moment.

  10. Hank Ledger · Lead AnchorIt's accepting the award on behalf of everyone who also did less when it got hot.
