Scientists study redwoods' reaction to warming
ARNOLD, Calif. (AP) — A new study aims to understand the effects of global warming on the world's largest trees — California's iconic redwoods and giant sequoias.
The $2.5 million project, funded by Save the Redwoods League, is sending experts hundreds of feet up into the trees' canopies to take measurements of their girth, bark and even the number of cones they have.
The researchers plan to return every three years to take new measurements. They are also installing sensors on the trees to measure fog temperature and other factors.
The study's locations include Big Basin in Santa Cruz County and Sequoia National Park in the central Sierra Nevada.
