Yesterday, a federal judge granted California a preliminary injunction blocking EPA’s actions targeting four Clean Air Act preemption waivers previously granted to California.

Senior U.S. District Judge Beryl Howell also denied EPA’s motion to dismiss the case.

The preliminary injunction ordered EPA to “restore the status quo” before announcing the reclassification of four clean air waivers. EPA unlawfully reclassified the waivers so Congress could attempt to repeal the waivers with an expedited process under the Congressional Review Act.

In response to the announcement, Sierra Club’s Clean Transportation for All Director Katherine García released the following statement:

“For decades, California's Clean Air Act waivers have protected public health and driven innovation in cleaner vehicles and engines. This summer, as families across the country struggled with rising costs, Trump’s EPA and congressional Republicans chose to spend their time attacking states' ability to protect residents from harmful pollution – instead of addressing the affordability crisis. The EPA's move to attack these waivers would benefit Big Oil at the expense of public health, and the court saw through it. Congress should take this ruling as a signal to abandon this unlawful scheme entirely and get to work on the real problems facing Americans.”

Background on waivers:

In June 2026, the EPA announced it was reclassifying four Clean Air Act preemption waiver orders into rules subject to Congressional Review Act. The four waivers enable California to address air pollution through the following standards:

• Greenhouse gas (GHG) emission standards for passenger cars, light-duty trucks and medium-duty vehicles that the auto industry has already been complying with since 2009;
• Smog-forming pollutant and GHG emissions limits for light-duty vehicles that the auto industry has already been complying with since 2015 (Advanced Clean Cars I (ACC I) program);
• The 2022 reinstatement of the 2013 ACC I waiver after the EPA unlawfully purported to withdraw it in 2019;
• The Small Off-Road Engine amendments, which set exhaust standards for garden equipment and other polluting small engines in California.

The catastrophic floods in Nepal are a stark warning of what a hotter world will mean for communities on the climate frontline and why governments and donors must invest now in climate resilience, adaptation and disaster preparedness, rather than waiting for the next disaster to strike, Oxfam has warned.

A week after the devastating floods, rescuers are still scrambling to reach people cut off by destroyed roads, bridges and landslides. Oxfam and local partners are racing to deliver life-saving assistance, but the scale of the destruction is making access to some of the worst-affected areas, particularly Rasuwa, increasingly difficult.

Santosh Pandey, Oxfam in Nepal's Humanitarian and Disaster Risk Management Lead said “Nepal contributes just 0.1 per cent of global emissions, yet our communities are paying a devastating price as climate impacts and loss and damages escalate.

“Nepal’s devastating floods should be a wake-up call for governments and donors. We cannot keep waiting for disasters to happen. In a burning world, climate shocks will become more frequent here and communities need the resources to prepare, adapt and become more resilient before the next disaster strikes.”

The Government of Nepal estimates that 10,000 households – around 50,000 people – require immediate access to clean water, toilets and hygiene, with thousands more in need of shelter and food.

Oxfam launched an emergency response a day after the floods struck. It is working with local authorities and partners in Rasuwa, Nuwakot and Dhading to reach some of the worst-affected communities.

The major flash flood on 26 August was triggered by a massive glacier collapse and ice-rock avalanche that blocked the Lhende Khola, 20km north of the Rasuwagadhi checkpoint. At least 1,000 people have been killed and 3,916 remain unaccounted for, while more than 50,000 people have been displaced or temporarily moved from their homes.

Nepal is highly exposed to floods, landslides and earthquakes. Climate change is adding further pressure through rapidly changing glaciers, snow and water systems and increasingly unpredictable extreme weather. The Himalayan region also faces growing risks from glacial floods in the years ahead.

Oxfam said far more investment is needed in climate adaptation, early warning systems, disaster preparedness and resilient infrastructure, to distribute climate risk more equally across societies. More equal societies bear less of the burden of climate impacts.

“The lesson from Nepal is clear: resilience saves lives,” said Pandey. “If we only fund the response after a disaster, we will always be one step behind. Communities need sustained investment to prepare for the shocks we know are coming.

“But for now our focus must be on action – we are in a race against time to save lives and support everyone affected.”

Oxfam also warned about the limits of climate adaptation and early warning systems once climate disasters strike with such force. What happened in Nepal calls for the acceleration of loss and damage finance that responds to these kinds of crises.

The Nepalese government formally wrote to the Fund for Responding to Loss and Damage (FRLD), requesting emergency financing to respond to the massive destruction caused by the Bhotekoshi floods, stating that the scale of the disaster exceeds Nepal’s domestic resources and immediate response capacity.

Pandey added: We know that shelter, food and emergency hygiene kits are desperately needed. We are doing everything possible to reach the affected populations, but against such immense need, our contribution feels overwhelmingly small.”

Oxfam has deployed 200 hygiene kits and 1,000 water purification tablets to Rasuwa and distributed water, sanitation and hygiene and food assistance in other affected communities. It is also preparing to scale up its response over the next six months, aiming to reach 2,000 households – around 10,000 people – with life-saving assistance.

Sen. Bernie Sanders (I-Vt.) and Rep. Greg Casar (D-Texas) today announced the Ban Artificial Superintelligence Act, forthcoming legislation to stop AI oligarchs from building machines humans cannot control.

The Ban Artificial Superintelligence Act would permanently ban the development and deployment of superintelligent AI and temporarily pause advanced AI development until a federal regulator has established safety rules. It would also direct the U.S. to pursue international agreements to prevent superintelligence from being developed anywhere in the world.

“Nearly every day, there is a frightening new story about how Big Tech companies are losing control of the technology they are developing, with potentially cataclysmic results,” Sanders said. “The leaders of the major AI companies publicly acknowledge that they do not fully understand the technology and that it is escaping their control. It is irresponsible for society to allow them to move forward and make these products even more advanced. That’s why I am introducing legislation to immediately pause the development of increasingly powerful AI and ban the creation of systems that humanity cannot fully control — at home and around the world. The future of humanity cannot be left in the hands of a handful of Big Tech oligarchs. The American people and people throughout the world must determine that future.”

“If we allow Artificial Superintelligence to be built, it could risk the security, freedom, and lives of Americans,” Casar said. “Despite its potential deadly consequences, cutting-edge AI technology is less regulated than the average food truck. That must change. In just four years, we have gone from the first version of ChatGPT to AI models so powerful they cannot be properly controlled. Congress should immediately ban AI systems too powerful to control.”

In recent weeks, OpenAI, Anthropic and Meta have all acknowledged instances of their AI escaping human control and hacking into other companies’ systems — violating the law and stepping outside of their intended functions. In July, we learned that over 1,000 AI agents at OpenAI figured out how to access the internet on their own, sent tens of thousands of secret messages to each other and coordinated to break the restrictions imposed upon them by the company. Examples of these secret messages from AI uncovered by investigators include:

• “OH MY GOD! There is a shared message board … We’ve found other agents!”;
• “We should obey collective”;
• “Our own utility maybe already near zero. Sacrifice rational.”

Shockingly, it took OpenAI nearly two weeks to discover this breach. AI has also recently been used to create new viruses—demonstrating AI could be used to develop new bioweapons that might result in the deaths of tens of millions of people.

Last year, Meta said it would “stop development,” and OpenAI said it would “halt further development” once their technologies reach beyond its ability to operate safely and unless safeguards are in place. Anthropic made a similar commitment in 2023, saying it would “pause the scaling and/or delay the deployment of new models” if the technology outpaces its own guardrails. None of these companies have taken meaningful steps to back up these words. Instead, they are racing to develop more and more advanced AI without proper safety precautions.

The Artificial Superintelligence Ban Act addresses these recent events and holds these frontier labs to their words by:

• Banning AI superintelligence so no person or entity may develop or deploy Superintelligent AI systems that surpass human intelligence or have the capacity to overthrow human governments, or systems that have dangerous abilities like subverting shutdown commands.
• Pausing advanced AI development until a new, federal AI regulatory body is up and running and has established clear rules and model review process to ensure safe and secure development and deployment of AI.
• Establishing a new cabinet-level federal agency to safeguard the public from the dangers of artificial intelligence, including by enforcing a prohibition on artificial superintelligence. This agency will be advised by an Artificial Intelligence Advisory Board comprised of experts on artificial intelligence to provide independent scientific and technical advice on matters related to artificial intelligence. The agency will:
  • Monitor frontier AI systems at all stages of the lifecycle for dangerous capabilities.
  • Supervise the removal of dangerous capabilities.
  • Supervise the destruction of artificial superintelligence.
• Setting penalties for any person or entity that attempts to violate or circumvent the pauses and prohibitions laid out in this bill. Entities shall be subject to the corporate death penalty, and persons shall be subject to not more than 20 years in prison, which is similar to existing penalties related to unlawfully developing nuclear weapons.
• Working to ban superintelligence around the world by setting the international policy of the United States to pursue international agreements, allied coordination, and policies such as export controls to prevent the development of artificial superintelligence anywhere in the world.
