The National Weather Service belongs to all of us; we rely on it for crucial and often lifesaving information. That is why we cannot let the Trump Administration weaken NOAA and put its National Weather Service behind a paywall. blog.ucs.org/juan-declet-...

Now is a critical moment to denounce and resist climate disinformation, pollution and violations of Indigenous sovereignty by the fossil fuel industry and its cronies.

1/3 UCS stands with @greenpeaceusa.bsky.social as it continues to fight attempts by #BigOilBullies to silence free speech and peaceful protest. As Greenpeace notes, this case is an alarming push by corporations to weaponize the courts to silence dissent. An attack on one is an attack on all.

NEW REPORT: Our latest analysis links nearly one-third of sea level rise today to emissions from 122 fossil fuel producers and cement manufacturers—and shows these emissions have guaranteed additional sea level rise for years to come.

The Climate Information Integrity Summit in Brazil is designed to expose the failures of the current information ecosystem to address the climate crisis, and drive concrete action to protect climate information integrity. Join the conversation: 3/25/2025. Live Streaming: ciis.caad.info

🚨New paper🚨 We attribute present day air temperature and sea level rise, as well as future projected sea level rise to the Carbon Majors, the 122 largest industrial fossil fuel and cement producers…more details below! iopscience.iop.org/article/10.1... 1/n 🧪 #scicomm #ClimateSky #ClimateChange

📢 @ucsusa.bsky.social analysis links nearly half of temperature rise and one-third of sea level rise today to emissions from 122 fossil fuel producers and cement manufacturers. Polluters must be held accountable for delayed action causing global impacts for generations to come. #MakePollutersPay

UCS joins 200 orgs warning about the potential for #BigOil to seek blanket immunity as it faces growing legal & legislative efforts to hold it accountable for decades of disinformation and its role in the climate crisis. We call on Congress to proactively guard against such a bailout.

In the first blog of a three-part series about climate models, UCS’s Marc Alessi explores the history of this important tool that scientists use to assess, amongst other things, how much the Earth’s temperature will change with increasing fossil fuel pollution in the atmosphere.

🚨NEW: Nearly 200 groups — including CCI — are urging Democratic leaders @schumer.senate.gov and @hakeem-jeffries.bsky.social to unite their caucuses to oppose any proposal that could give immunity to the fossil fuel industry and shield Big Oil from accountability. www.theguardian.com/us-news/2025...

Today, EPA's Lee Zeldin announced rollbacks on key environmental regulations, including pollution limits for coal plants, climate rules & EV standards. He called it a “consequential" day of deregulation, but for those who care about clean air & water, it's one of the most destructive in US history.

Our series of free Pocket Guides cover topics ranging from safeguarding online communications, to navigating the First Amendment, to how to handle legal intimidation & political harassment, & more: www.csldf.org/resources/?r...

BREAKING: Hundreds of members of communities harmed by the fossil fuel industry, faith leaders, young people, and others held a powerful march + action to confront the fossil fuel billionaires gathered in Houston for #CERAWeek, the Superbowl of oil and gas conferences.

#SaveScienceSaveLives #StandUpForScience

BREAKING: The Supreme Court has denied a motion from 19 attorneys general to stop climate deception lawsuits against Big Oil from five states — CA, CT, MN, NJ, and RI. This is the 2nd time this year the justices declined to consider arguments aiming to shelter Big Oil from accountability.

You know it's a good day when Beaker has your back. Amazing energy today at the #StandupforScience2025 @standupforscience.bsky.social rally in DC. Thank you all and let's get to work! 🧪📣

Mon 3/10: Join groups in Houston protesting #CERAWeek, a conference that features some of the world’s biggest polluters including Shell, BP, ExxonMobil, Chevron & ConocoPhillips. Show solidarity with Gulf South communities fighting for climate & environmental justice ✊🌎 #MarchForFutureGenerations

As more Illinois residents and businesses transition away from expensive, polluting fossil fuels, we need a strong power grid that protects ratepayers from drastic price changes. Tell your legislators to support the Clean & Reliable Grid Affordability Act:

Did you know? Half of global fossil CO2 emissions in 2023 were linked to just 36 companies. A 🆕 update to the Carbon Majors database shows the disproportionate contribution of a small number of high emitting companies to the GHG emissions damaging the planet. 🏭👉 carbonmajors.org/briefing/The...

Today @influencemap.bsky.social published an updated data set showing that half of all global fossil CO2 emissions in 2023 could be linked to *just 36 companies.* Unsurprisingly, the highest emitting investor-owned companies were ExxonMobil, Chevron, Shell, TotalEnergies, and BP.

Join UCS and allies to #StandUpForScience this Friday, March 7 in DC and around the country! We will be demanding funding for life-saving science, an end to censorship & political interference in science, and defense of diversity, equity, inclusion & accessibility in science. Find a rally near you:

“And, yes, in case you were wondering, these outlooks depend in part on data from NOAA’s National Weather Service. Another reason why the Trump administration’s attacks on NOAA make no sense,” writes UCS's Rachel Cleetus.

NOAA's work matters! We all need to act like it does. 🌎 🧪🌊 @ucsclimate.bsky.social @ucsusa.bsky.social @altnoaa.bsky.social

#Project2025 specifically calls for #NOAA to be “dismantled,” “downsized,” and “eliminated,” recommending the privatization of its essential functions. Frank Schwing, Science Network member and retired federal scientist, explains how your community’s safety and prosperity rely on NOAA. #ProtectNOAA

“The massive reduction in staff at FEMA will have dangerous ripple effects for communities across the country,” said Shana Udvardy, senior climate resilience policy analyst at UCS. “At a time when FEMA staff is low capacity, this is going in the wrong direction.”

Really important work from my former colleagues @ucsusa.bsky.social and @ucsclimate.bsky.social. 🧪🌎🌊

President Trump’s “work stop” order has prevented US federal scientists from participating in the meeting on the IPCC’s forthcoming Seventh Assessment Report (AR7). How does this decision impact international climate collaboration, and what can we expect moving forward?

The Trump Administration is attacking National Oceanic and Atmospheric Administration (NOAA) Scientists are fighting back.

“These defendants prioritized their profits over the people of Minnesota, and deception was their business model,” Minnesota Attorney General Ellison said. “The court’s thorough analysis and well-reasoned order puts us one step closer to proving that in court.” climateintegrity.org/news/view/co...

Big Oil companies should face charges that their coordinated climate deception violated federal racketeering and antitrust laws, a judge recommended in a groundbreaking lawsuit brought by Puerto Rico municipalities. climateintegrity.org/news/view/pu...

EPA Administrator Lee Zeldin has reportedly urged OMB to strike the EPA’s “Endangerment Finding”—a key scientific and legal basis for curbing heat-trapping emissions that fuel climate change and endanger public health. This move threatens critical safeguards. (🧵)

Join this adorable activist dog we met at #AAASmtg in #EvidenceBasedOutrage Demand Congress do everything in their power to end DOGE, stop all unconstitutional & illegal activity by the Trump admin, and force the exec branch to respect the separation of powers. ➡️ secure.ucsusa.org/a/2025-stop-...

"Indigenous and Western scientists can co-exist, but in order for this to happen, non-Natives must recognize and set aside their harmful stereotypes of Native peoples, including that we can magically solve climate change." Learn more in our guest blogger Samantha Chisholm Hatfield’s post.

Elon Musk, the unelected head of “government efficiency,” demanded federal employees report their weekly accomplishments—or risk their jobs. Let’s not ignore what federal scientists actually do. Here’s what they achieved last week (and every week)📤

Energy Transfer - the #BigOil company behind the Dakota Access Pipeline - is suing @greenpeaceusa.bsky.social in an outrageous lawsuit that could set a dangerous precedent of silencing the free speech of unions, activists, and journalists. #WeWillNotBeSilenced

BREAKING: We crashed Chubb insurance's annual golf tournament. Chubb is one of the top fossil fuel insurers in the world and they pour billions of dollars into methane gas every year.

The Trump administration is attacking scientific integrity by unlawfully seizing control of NOAA, the agency that monitors and issues weather alerts. Juan Declet-Barreto explains the far-reaching consequences if these plans under #Project2025 move forward. Blog: act.ucsusa.org/4k70EsF

“The world we knew even 20 years ago has been forever altered by the costly & deadly impacts of continued use of harmful fossil fuels. Rather than recklessly cutting agency staffing & budget, the Trump admin and Congress should be investing in programs and policies that better protect people"
