Trees' Leaves Grow At a Cool 70° All Over the World

biogeochick writes "Ever turn on the air conditioner on a hot day? How about a heater when it gets cold? OK, so we all know that humans act to keep themselves cool, but what about trees? A recent article on tree core isotopic evidence has shown that trees from tropical to boreal forests all grow at 70 degrees. The study, published in Nature by some fantastic researchers (so one of them is my adviser, so sue me) and covered by NPR on All Things Considered, has shed some light on the convergent temperature at which trees perform photosynthesis." Update: 06/19 21:31 GMT by T : I give, I give -- that's 70 degrees Fahrenheit.

      I think it's quite clear what degrees was referring to...the only problem was they didn't indicate whether it was North, South, East or West, so you can't tell whether they're talking about latitude or longitude. Either way, I think they're saying they've located the last grouping of trees left on the planet.

      Trees do have quite a long lifespan you know, much longer than humans.

      A tree in general has more than enough time time in its life to :

      - heat up to 70C and burn all its leaves off,

      - cool down to 70F and grow them all back again,

      - complete 70 various degrees ranging from "Bachelor of the justification of stealing someone elses wifi" all the way to "Masters in the creation of piss-poor wifi analogies", during which time it likely met a lot of /.ers

      - run out of lame 70 degrees jokes to make because after the three obvious ones everyone starting converting 70 to every other fucking useless unit under the sun
