Pasadena weekend: February 13-15

Learn about a JPL project on global warming or about edible wild plants; help restore a trail; garden or walk. Plus: ongoing and recurring events.

No way back: Charting Irreversible Climate Change is the title of a JPL presentation on Friday night of the project Jason 3, which will serve as a set of eyes on sea level rise. By measuring global sea level once every 10 days, Jason 3 will chart out the global rise of the oceans, which is unlikely to subside or reverse for generations.

Trail restoration. Join the San Gabriels Trail Crew, an entity of the Sierra Club, on Saturday to help restore one of the historic trails damaged by the 2009 Station Fire and subsequent erosion.

Water and You is the title of a four-part workshop series that the Neighborhood Church’s Green Council has organized. The second session, on Saturday afternoon, will explore the topic California Water Supply. Free and open to the public.

Walks, docent-led. Descanso Gardens (La Canada) is holding docent-guided seasonal walks on Saturday and Sunday morning. On Friday and Saturday morning, the Arboretum (Arcadia) will host docent-led walking tours. On Sunday morning there will be a bird walk at the Eaton Canyon Nature Center.

Gardening, workshop. On Saturday morning, The Huntington (San Marino) will host a workshop with garden designer and food forager Nance Klehm exploring the role of edible wild plants in sustainable urban agriculture.

Gardening, hands-on. Transition Pasadena's Throop Learning Garden (usually) meets on Sunday mornings.

Petition, surveyChange.org's petition for a ban of styrofoam containers in Pasadena is still up and active. Pasadena Water and Power is conducting a survey on the city's energy future. (Note: PWP has not posted any information on when the survey period ends, but as of this printing the link was still up.)

Got kids? On Saturday morning, the Eaton Canyon Nature Center is hosting a family nature walk. Bring your small children, walking shoes, sunscreen, water and a hat. Also on Saturday morning at the Nature Center: the weekly Nature Tails Story Hour which includes stories, nature walks and puppet shows for children ages 3-5.
