Federal scientists must be protected from political attack. Federal agencies are working to safeguard research but more must be done. Learn what’s at stake and what you can do to help. wapo.st/4cAd203 When science is sidelined, people get hurt. We’ve documented more than 300 attacks on science that show why protecting science and scientists is so important. act.ucsusa.org/37qIVGd

Congress must act quickly to reach a #DebtCeiling agreement and avoid a catastrophic default, which would harm the economy and disproportionately hurt low-income households. No #DefaultOnAmerica The #DebtCeiling deal announced over the weekend shows some progress BUT contains some very damaging provisions that would harm public health and well-being and the environment, especially in frontline communities and communities of color.

We're wrapping up National Farmworkers Awareness Week with a thread! Farmworkers make our food system run. But they shoulder a lot of risk. Daily life is full of dangers for the estimated 2.4 million farmworkers in the US, most of whom are Hispanic and Indigenous. #NFAW2023 Working outdoors is hard, dangerous work: Farmworkers die of heat-related causes at a rate 20 times greater than other professions. In hot agricultural centers like California's Central Valley, that number is even higher. act.ucsusa.org/3wju1lg

Yesterday we talked about the threat the events of Jan. 6 posed to our democracy. But #Jan6 also highlighted a threat to our entire planet. Why? Outdated and dangerous policies give @POTUS sole authority to launch a nuclear strike & no one can stop it once issued. (🧵) – Two days after the capitol riot, concerns about then-president Trump led House Speaker Pelosi to ask the head of the US military, Joint Chiefs Chairman Gen. Mark Milley, about "preventing an unstable president from...ordering a nuclear strike. politico.com/news/2021/01/0…

Today, California's @AirResources held a workshop on electric truck infrastructure. Investments in charging infrastructure and deployment of electric trucks are critical, as is a strong Advanced Clean Fleets Rule, to getting zero-emission trucks on the road. A strong electric truck fleet rule will create certainty in the heavy-duty charging infrastructure marketplace & send a clear signal that we must continue momentum on the investment & buildout of zero-emission fueling tech. #ElectricTrucksNow @mslianeran ElectricTrucksNow.com

Hurricane season officially started yesterday. In the lower 48 states, there are 126 counties at risk of storm surge from a Category 5 hurricane, according to NOAA. Based on our analysis, just 36% of eligible people across those counties is fully vaccinated. The Gulf Coast is home to hundreds of large petrochemical plants, oil wells and refineries, and Superfund sites containing large quantities of toxic material. Every hurricane strike has the potential to expose people in the area to even greater concentrations of toxic chemicals.

We are encouraged by the Biden administration’s initial actions and science-based plan to address the #COVID crisis, but recognize that ALL OF US must act to bring the virus under control and prevent more needless deaths. int.nyt.com/data/documentt… Science clearly shows that masking up and social distancing are essential to bringing the virus under control. Requiring masks on all federal property is a good step, but EVERYBODY should be wearing a mask in public, no matter where they are. act.ucsusa.org/39dmrNt

Here's a good piece by @izzieramirez@vicenews highlighting environmental justice! Thank you for including UCS. We wanted to take this opportunity to clarify UCS is not primarily an environmental justice org & why it's important to uplift orgs that are. vice.com/en/article/jgx… Grassroots environmental justice groups often have to struggle for funding and attention, even as they’re representing the communities most overburdened by environmental issues. It’s important these groups get the credit.

Meet Dr. Scott Atlas, who has effectively replaced Dr. Anthony Fauci as the chief science advisor to the White House’s #Coronavirus Task Force. forbes.com/sites/mattpere… Dr. Atlas is unqualified for the job, has no background in epidemiology as a radiologist, and is pushing pandemic policies not backed by evidence. He is actively advocating for a “herd immunity” strategy that would needlessly endanger the lives of people. washingtonpost.com/politics/trump…

California's Bay Area wakes up to disorienting orange skies. By raising temperatures, melting snow sooner, and drying soils and forests, climate change is fueling #Wildfires. Here’s a thread on what the science shows. twitter.com/i/events/13037… #1: Wildfires are getting worse. Since 2015, the United States has experienced, on average, roughly 100 more large wildfires every year than the year before. Image

Charleston, South Carolina just became the first city in the US South to take fossil fuel companies to court for their role in climate change. #MakePollutersPay thestate.com/news/local/cri… Under current trajectory, over 1,600 homes in Charleston are at risk for chronic flooding in the next 25 years and over 7,000 are at risk by the end of the century.

THREAD🧵: In July, the Trump administration abruptly told the CDC to stop collecting and publicly sharing current data on #COVID19 hospitalizations, ICU beds, and PPE. The results have been as predictable—and unacceptable—as expected: nytimes.com/2020/07/14/us/… Image COVID data collection shifted to a third-party under Health & Human Services and subject to potential political influence. The firm has repeatedly refused to answer questions about its contract & data collection, which—unlike the CDC—are not fully public. nytimes.com/2020/08/14/us/…

The Trump admin’s EPA has launched a new attack on the #CleanAirAct, this time by reinventing math. Tell the EPA to not sideline the science that supports strong air pollution standards. File a comment by Monday, August 3. Protect our clean air today! act.ucsusa.org/2PaLl5a Why is the admin messing with math? Because the science on air pollution is inconvenient for powerful industries who want to roll back public protections. @GretchenTG and @_aploy explain: blogs.scientificamerican.com/observations/h…
