Friend, we still haven't reached our goal of 1,000 new members yet…and the clock is ticking.

We need a powerful membership to stand with us as we gear up for the challenges ahead – fighting climate change, defending endangered species, stopping toxic pollution, and much more. Will you join us before tonight's midnight deadline?

Join the Sierra Club before the Summer Membership Drive ends, and we'll send you a FREE Adventure Blanket as a token of our thanks!

Your membership gift of just $15 or more will power the Sierra Club's tireless, high-impact work to build a healthier, safer environmental future for all, including:

• Pushing Congress to protect threatened wildlife by strengthening the Endangered Species Act – one of the most successful tools we have to save animals like gray wolves, grizzly bears, and North Atlantic right whales from extinction. Join today to help defend our wildlife and you'll get a FREE Adventure Blanket.


• Blocking the fossil fuel industry's climate-wrecking expansion by rallying activists nationwide against some of the world's biggest investors in coal, oil, and gas extraction. We can't win the fight for our climate without you – become a member now.


• Putting pressure on the Biden administration to expand protections for public lands, including the vulnerable mature and old-growth forests we need to help fight climate change. Together, we can win more victories for our forests, deserts, waters, and more – join the Sierra Club before the midnight deadline.

At a time when our wild places, our communities, and our Earth face so many grave threats, I'm heartened to know that we can count on people like you to take action for the planet when it matters most. Thanks for sticking with us, Friend.

With gratitude,


Dan Olinger (he/him)
