Announcing Sierra Club’s New Executive Director

It is with great excitement that I write to you, as President of the Sierra Club, to share the news that the Board of Directors just voted unanimously in support of Ben Jealous, an experienced civil rights leader, community organizer,  and coalition builder to be our new Executive Director.

We’re thrilled to welcome Ben to our organization. Ben’s passion for the outdoors and commitment to fighting for the environment, and his work leading People for the American Way and the National Association for the Advancement of Colored People (NAACP) – two of the nation’s most influential groups pursuing equity and justice and protecting democracy – makes him uniquely qualified to lead the Sierra Club at these intersections as our journey continues to create a healthy and sustainable planet for all.   Read more here.


On April 8, the California Coastal Commission approved the annual closure of Pt. La Jolla and most of Boomer Beach May 1 to October 31, for the sea lion pupping season.  The Sierra Club Seal Society presented the science and expert testimony to achieve this significant goal.  But our work has not ended.  The Coastal Commission agreed with the Club that a long term management plan was needed to adress the harassments that take place when the site is open.  Our next steps will be to ensure rthe management plan is the best to protect this natural wonder.   We also need volunteers to help us as we conduct counts of mothers and pups during the closure and help educate visitors.  You can volunteer HERE.
