Environment reporter Lynda V. Mapes appeared on Q13 Fox this morning to discuss her book, "Witness Tree," and how it reexamines climate change from the perspective of a century-old tree.

"As a reporter, I was looking to cover climate change differently - to see the quiet testimony of nature," said Mapes.

"Here you are seeing a global phenomenon all the way inside the cellular function of the leaves."

Mapes will be launching her book at Seattle Public Library on Tuesday, Apr. 11 from 7-8:30 p.m.
