PEANUT BUTTER CLUB: Presents the video “Yosemite” on Friday, February 7, at noon, in Redfield Auditorium, 45 Water St., Woods Hole. Yosemite Valley is a land forged in wildfire and sculpted by water; the delicate balance of these two elements is essential to the creatures and trees that call this land home. But with climates changing and temperatures rising, the Sierras are under siege. Scientists, experts and adventurers head into Yosemite to see how these global changes are affecting one of America’s greatest wildernesses. Sponsored by the WHOI Visitor Center. Coffee, tea, and cookies served. Donations accepted.
