I like Kevin Anchukaitis's posts on the NYTimes Scientist at Work blog about studying Guatemala's climate history through tree rings! Here's the first one.

"Andrew E. Douglass, the astronomer who founded dendrochronology, wrote, 'Through long ages past and with unbroken regularity, trees have jotted down a record at the close of each fading year — a memorandum as to how they passed the time.'"



















Happy vernal equinox!
