On the opening day at COP30, the United Nations’ annual climate summit, the scene was emblematic of a shifting order. With the United States absent, all eyes were on China. ✍️ 📸 Nour Ghantous

The Trump administration is moving to weaken the Endangered Species Act, possibly threatening protections for vulnerable wildlife and opening the door to habitat loss and extinction—even as broad bipartisan support for the ESA remains strong nationwide. 🔗 bit.ly/4o73iPY

This week, the House is voting on measures that would open the Arctic and other irreplaceable places to destructive oil and gas leasing. We need to speak up.

"By entering this exchange, the Trump administration is tearing up a plan they themselves designed and advancing a version that will be even more destructive to fragile landscapes and wildlife populations." - @sierraclub.org's Athan Manuel.

This week we are honoring and uplifting the courage, service and sacrifice of our military veterans — and we're especially proud of how getting outside, together, can make a difference.

This weekend, the New York Times ran a story claiming Sierra Club’s values have diluted our mission. They couldn’t be more wrong. The list of their errors is too long for one social post, but we go over some examples in these slides.

The Florida wildlife commission has approved a bear hunt despite the objections of Floridians. Even the state agency has debunked one of the primary justifications for the hunt, which is that bears will run out of habitat. Now, advocates are mounting a novel way to save the state’s bears.

In 2024, the planet crossed what many scientists consider a dangerous threshold: It warmed to about 1.55 °C above pre-industrial levels, passing the Paris Agreement’s 1.5 °C threshold. That same year, American utility companies largely failed to do their part to ramp down fossil fuel usage.

With the federal government shut down, states aren’t getting the funds they need to help low-income families pay rising utility bills. Power shut-offs during extreme weather can be deadly. We’re calling on utilities to keep the lights on during the shutdown. ⚡️

These migratory birds were leaving New York and never returning. Their disappearance stumped the researchers who banded them. However, their discovery led to an unlikely partnership between a coastal Brazilian community and an ornithologist in the US. ✍️ Jill Langlois 📸 Afonso Farias

“The Trump administration is weaponizing the government shutdown to gut staffing, weaken environmental protections, and normalize their ultimate goal of privatizing public lands,” writes @jackieostfeld.bsky.social in @thehill.com . thehill.com/opinion/ener...

🚨 We just launched an interactive tracker analyzing the proxy voting guidelines of major U.S. public pensions. 🔍Take a look & learn how these influential investors decide where to cast their votes on shareholder proposals at major corporations.

In March, an EPA official told a Ford executive, “Although I am recused from Ford issues, you always have a friend here.” Then, Trump banned states from setting vehicle emissions standards. In our latest FOIA request, we dive into which groups have the EPA's ear: sc.org/FOIA

For decades, this small but mighty Arctic research collective shaped what we know about the fastest-warming region on Earth—linking scientists, funding studies, and uplifting Indigenous knowledge. Last month, it shut down after federal funding was cut. 🔗 bit.ly/47uOjKE

A beautiful spot in Alaska, north of the Arctic Circle, is an essential habitat for many animals. That area, more than 10 times the size of Yellowstone, is at risk.

In an unprecedented move, Senate Republicans just voted to erase public land plans in AK, MT, and ND, all to benefit corporate polluters. And they're not done yet: similar resolutions have already been introduced. Tell your members of Congress to choose the people over polluters: sc.org/LandsAction

In September, SC staff & volunteers traveled to D.C. to participate in Wilderness Week to ask Congress to protect our public lands, support the Roadless Area Conservation Act, and safeguard park rangers & other stewards of shared lands.   sc.org/RACA sc.org/LandsAction @natlwilderness.bsky.social

Sierra Club's @jessyewaxman.bsky.social talks with @inthesetimes.com about our work to push pension to stop buying new bonds issued by fossil fuel companies hoping to raise 💰💰💰 for pipelines, refineries & more.

Trump shut down the federal government, but ordered national parks to stay open. "Forcing national parks to operate without sufficient support, simply to maintain the illusion of openness, puts visitors, staff, and the land at risk." @JackieOstfeld.bsky.social www.sierraclub.org/press-releas...

Trump just handed $625M to Big Coal + opened millions of acres for mining. Meanwhile, utilities are STILL clinging to expensive fossil fuels. Our 5th Dirty Truth report shows the cost is falling on families. #DirtyTruthReport sc.org/dirtytruth

The Trump EPA's comment period for its dangerous proposal to attack critical climate protections has come to an end. Read our recap of how the Sierra Club community spoke out against the rollback of #CleanerCars and #CleanerTrucks: www.sierraclub.org/articles/202...

The effects of wildfires last for years after the blaze has been extinguished. The ongoing problems in New Mexico highlight how local, state, and federal systems aren’t equipped to handle the prolonged recovery associated with increasingly large and destructive wildfires. 🔗 bit.ly/4n1Ne2f

The Sierra Club’s member-elected Board of Directors has unanimously appointed Loren Blackford as our next Executive Director, making her the first woman to lead the Sierra Club in our 133-year history!

"The Trump administration does not care about your family’s health and safety. They do not have a plan to protect you and the people you care about from dangerous pollution, extreme weather events and he worsening climate crisis."

The Sierra Club strongly condemns political violence. That this is required to be said speaks to the terrifying increasing pattern of political violence which cannot be ignored.

Don't let them destroy our last wild forests. Did you know that the Trump administration is threatening protections for nearly 60 million acres of our wildest forests?

Industrial boilers are a little-known piece of manufacturing equipment with a BIG pollution impact. They use fossil fuels to heat water & produce steam used in processes like pasteurization. Thankfully, zero-emissions, electric alternatives are growing. www.sierraclub.org/boilers101 @sierraclub.org

Congress wants to overturn land plans in AK, MT & ND—gutting protections for wildlife, recreation & Tribally-important lands. If they succeed, it could unravel how ALL public lands are managed. Call (855) 980-5638 and tell your rep to vote NO on the Congressional Review Act (CRA) resolutions.

NEW: The Sierra Club Foundation just hired Sara E. Murphy as the Director of Shifting Trillions, an initiative to catalyze capital in favor of a sustainable future. Below is a look at Sara, the Shifting Trillions campaign, and the importance of sustainable investing 👇

The Trump admin plans to gut funding for the independent board investigating the deadly explosion at a US Steel facility in Pennsylvania. This critical work must continue to keep ALL communities safe from future industrial accidents.

“It’s a new paradigm when you’re operating and fulfilling all the needs of these manufacturing heat processes without causing health-harming pollution.”

Cheese. Beer. Clothes. Paper. – Read Canary Media’s latest coverage on the impact of industrial heat pumps that can both meet the needs of manufacturers and "allow communities to breathe easier."

“A lot of people may not think about the role of industrial manufacturing in local air pollution, or in terms of climate change, but it can be a significant factor and cause real health harms,” said Will Barrett of the American Lung Association. Read more from @grist.org:

Industrial heat pumps could be a game-changer. This newest @Grist.org article highlights a new report from the American Lung Association shows that phasing out fossil-fueled boilers in manufacturing could save lives, improve air quality, & save countless lost school days.

Glass and aluminum can be recycled endlessly, but plastic has a limit. Almost all the plastic ever created is still with us, polluting our planet. What if we had a better way to recycle it? Nature might offer one solution. ✍️ Lindsey Botts 🔗 www.sierraclub.org/sierra/2025-...
