Endangered species such as grizzly bears and gray wolves migrate from Yellowstone National Park into the roadless areas of Custer-Gallatin National Forest. The Forest Service is deciding how to manage this forest for the coming decades, but its draft plan fails to adequately protect wildlife habitat.

"When it comes to taking action on climate, it's important to think big, like calling for 100% clean energy,” says Lisa Hoyos, director of the Sierra Club's Climate Parents program. "Parents are coming together to make a powerful impact, and everyone can get involved.”

The Sierra Student Coalition's summer program—"Sprog" for short—is a one-week leadership training program that provides young people from all across the country with tools and strategies for effective environmental and social justice activism.

Nathaniel Rich's new book, Losing Earth, chronicles how during the 1980s there was a clear scientific consensus that humans were heating up the planet by burning fossil fuels. Why didn’t scientists, policy experts, and members of both the Republican and Democratic parties do something?

Pete Ramey, a Virginia coal miner turned environmental activist and a longtime friend of the Sierra Club, died this March at the age of 90. After 40 years in the mines, Ramey devoted the rest of his life to stopping the practice of mountaintop-removal (MTR) coal mining. “He was a trusted voice in representing people who all too often are forgotten,” says retired Sierra Club organizer Bill McCabe.

The Extinction Rebellion (XR) is a fast-growing international movement calling for an immediate government response to climate change, species loss, and imminent ecological collapse. The movement’s tactics emphasize disruption over negotiation, and its platform demands that governments “tell the truth” by declaring a climate emergency; reduce greenhouse emissions to net zero by 2025; and create a "citizens' assembly" to advise the transition.

Can the Extinction Rebellion succeed where less radical movements have not?

As summer approaches and temperatures rise, so does our electricity use—and unfortunately, much of that power is still generated by burning coal and other fossil fuels. But there's a better, cleaner way. Our partnership with SunPower makes it easy for Sierra Club members and supporters to go solar. When you go solar with SunPower and the Sierra Club, you’ll receive a $1,000 mail-in rebate and the Sierra Club will receive $1,000 to support our work to explore, enjoy, and protect the planet.

Nellis Kennedy-Howard, director of Equity, Inclusion, and Justice for the Sierra Club, has written an article for Autostraddle about raising her baby to celebrate their Diné heritage by hunting, fishing, and beading, no matter their gender. “I want all the richness of every cultural tradition in their background to be available to them,” Kennedy-Howard says. “I look forward to taking them to our family hunting spot and climbing an old pine tree that overlooks a valley of aspen that I know as well as I know myself.”

Read Kennedy-Howard’s deeply felt article.

State and local leaders from coast to coast are working together with a shared vision of transforming the US into a nation where every community is ready for clean air, affordable energy, and access to the clean energy economy. The Ready For 100 Chicago Collective, an offshoot of the Sierra Club’s Ready For 100 campaign, recently convinced their city to commit to 100% renewable energy.

If our democratic norms and the rule of law count for little, as the current occupant of 1600 Pennsylvania Ave. seems to believe, then the legal and democratic tools we use to combat climate change and protect our air, water, public lands, and wildlife habitat could be trivialized as well. Congress has the right—in fact, a constitutional duty—to oversee the executive branch. It must continue its constitutional oversight duties by following the evidence laid out in the Mueller report.

Tell Congress to continue obstruction of justice hearings and keep demanding the full, unredacted Mueller report.
