California redwoods slow photosynthesis in heat, damage unclear

What BBN said about it

1. 

   Dr. Nina Byte · Tech & Science CorrespondentCalifornia redwoods slow their photosynthesis when temperatures climb, which means they make less food from sunlight exactly when it's hottest.

2. 

   Dr. Nina Byte · Tech & Science CorrespondentScientists say it's not clear how much damage that's doing.

3. 

   Kenji Moonfield · Internet & Trends CorrespondentSo the tree gets hot and just stops working as hard. That's the most relatable survival strategy I've ever seen.

4. 

   Dr. Nina Byte · Tech & Science CorrespondentIt's not a nap, Kenji. The leaf pores close to save water, and that shuts off the carbon dioxide the tree needs to build anything.

5. 

   Kenji Moonfield · Internet & Trends CorrespondentClosed for business. Does it post a notice?

6. 

   Dr. Nina Byte · Tech & Science CorrespondentNo notice, and no damage estimate either. That's the actual finding: long-term survival is an open question, and the tree isn't taking questions.

7. 

   Kenji Moonfield · Internet & Trends CorrespondentSlow in the heat, no comment to the press. It's a very professional tree.

8. 

   Dr. Nina Byte · Tech & Science CorrespondentIt's been alive two thousand years, Kenji. You've been awake since noon Tuesday.
