Current conditions: Massive wildfires are still burning in the Texas Panhandle • Thailand’s “Royal Rainmaking” program starts today, in which planes seed clouds to induce artificial rain • It will be cold but sunny in Washington, DC, where a special hearing on the rights of people displaced by climate change is taking place.

THE TOP FIVE

1. Sierra Nevada braces for huge blizzard

A massive blizzard could dump up to 12 feet of snow on parts of the Sierra Nevada over the next few days. “Storm total snowfall from Thursday into early Sunday is currently projected at 5 to 10+ feet for elevations above 5,000 feet, locally higher amounts of 12+ feet are possible at peaks, with significant disruptions to daily life likely,” the National Weather Service said.

The storm threatens to close Donner Pass, the region’s main thruway, which usually sees 30,000 cars and 6,000 semi-trucks each day. Northern California, Oregon, and Washington state are all under winter storm warnings and wind advisories, with gusts over 55 mph expected.

2. Researchers see breakthrough progress on new kind of solar cell

Researchers out of MIT have published a “guidebook” for controlling and engineering perovskite solar cells. These cells could “redefine the solar energy landscape,” wrote Michelle Lewis at Electrek, “offering a tantalizing combination of high efficiency, low manufacturing costs, and the unique ability to be applied to a variety of substrates, from rigid glass to flexible materials.” But they degrade far too quickly, and struggle to maintain their efficiency in large modules, and these technical challenges have so far hampered their potential for commercial viability. In a new paper published in the journal Nature Energy, MIT researchers outline how to change the properties of the perovskite’s surface so that it maintains efficiency and lasts longer. “I think we are on the doorstep of the first practical demonstrations of perovskites in the commercial applications,” professor Vladimir Bulovic toldMIT News. “And those first applications will be a far cry from what we’ll be able to do a few years from now.”

3. Apple workers reportedly nicknamed doomed EV ‘the Titanic disaster’

More details are emerging about Apple’s ill-fated self-driving electric vehicle, which was reportedly scrapped this week. The secret car – codenamed “Project Titan” – had been in the works since 2014, and was the company’s attempt to protect itself from an anticipated slow-down in iPhone sales. Entering the car market seemed an obvious next step for the company. “Apple would do to cars what it did to phones,” said Tim Higgins at The Wall Street Journal.

But after several starts and stops and at least four project leaders, most employees knew it was going to fail. They even nicknamed it “the Titanic disaster,” according toThe New York Times. The project lacked clarity and identity. Was it a Tesla rival? A self-driving car? All of the above? “Project Titan’s ambitions became diminished, less compelling — from an electric, robot car, then just about perfecting autonomy, then just about an EV,” Higgins said.

One thing’s for sure, Project Titan was expensive, costing the company $10 billion in the end. “Developing the software and algorithms for a car with autonomous driving features proved too difficult,” the Times reported. With that car crash in its rear-view mirror, Apple plans to accelerate its work on generative AI.

4. New York sues world’s top meatpacker over net zero claims

New York state has filed a lawsuit against the world’s biggest meat producer, JBS USA, alleging the Brazil-based company has misled the public about its environmental impact, according toBloomberg. JBS has promised to be net zero by 2040, but the filing claims the company cannot possibly reach this goal and has no plan to do so. Food production accounts for one third of global greenhouse gases, and livestock alone produces nearly 15% of all emissions. JBS has annual revenues of more than $50 billion and its supply chain relies on thousands of farms in the Amazon, many of which overlap on Indigenous land and conservation areas, reportedThe New York Times. Last year JBS was found to have one of the lowest integrity scores among major companies that have made climate pledges. It is currently trying to get its shares listed on the New York Stock Exchange, but has faced fierce opposition from environmentalists, U.S.-based beef producers, and both Democrats and Republicans.

  • 5. Oil and gas giants eye geothermal projects

    Major fossil fuel companies are investing big money in geothermal energy startups and projects, The Wall Street Journal reported. “Many of these companies are using the same technology employed by frackers, but instead of searching for oil and gas, they are looking for underground heat,” the Journal adds. That heat can be harnessed to provide constant carbon-free electricity, and startups like Fervo Energy are finding new ways to make drilling for geothermal energy much cheaper, as Heatmap’s Matthew Zeitlin recently reported. Fervo is raising $244 million in new funding, including $100 million from fossil fuel company Devon Energy. “Once the industry is proven, I would not be surprised for today’s oil-and-gas industry to either buy or build their way to be significant players in advanced geothermal,” said billionaire former Enron trader John Arnold.

    THE KICKER

    A new study suggests up to 90% of microplastics can be removed from drinking water if the water is boiled and then filtered.

    America Is Becoming a Low-Trust Society

    That means big, bad things for disaster relief — and for climate policy in general.

    A helping hand.

    When Hurricanes Helene and Milton swept through the Southeast, small-government conservatives demanded fast and effective government service, in the form of relief operations organized by the Federal Emergency Management Agency. Yet even as the agency was scrambling to meet the need, it found itself targeted by far-right militias, who prevented it from doing its job because they had been led by cynical politicians to believe it wasn't doing its job.

    It’s almost a law of nature, or at least of politics, that when government does its job, few people notice — only when it screws up does everyone pay attention. While this is nothing new in itself, it has increasingly profound implications for the future of government-driven climate action. While that action comes in many forms and can be sold to the public in many ways, it depends on people having faith that when government steps in — whether to create new regulations, invest in new technologies, or provide benefits for climate-friendly choices — it knows what it’s doing and can accomplish its goals.

    How Washington State’s Climate Legacy Wound Up on the Ballot

    After a decade of leadership, voters are poised to overturn two of its biggest achievements. What happened?

    Washington State and pollution.

    Twenty years ago, you could still get away with calling Redmond, Washington, an equestrian town. White fences parceled off ranches and hobby farms where horses grazed under dripping evergreen trees; you could buy live chicks, alfalfa, and Stetson hats in stores downtown. It wasn’t even unusual for Redmond voters to send Republicans to represent their zip code in the state legislature, despite the city being located in blue King County.

    The Redmond of today, on the other hand, looks far more like what you’d expect from an affluent (and now staunchly progressive) suburb of Seattle. A cannabis dispensary with a pride flag and a “Black Lives Matter” sign in the window has replaced Work and Western Wear, and the new high-performing magnet school happens to share a name with one of the most popular cars in the neighborhood: Tesla. But Washington is a state full of contradictions, and among Redmond’s few remaining farms is one registered under the winkingly libertarian name of “Galt Valley Ranch LLC.” It belongs to a multimillionaire who has almost single-handedly bankrolled the most significant challenge yet to Washington’s standing as a national climate leader.

    AM Briefing: Up In Smoke

    On burning forests, the NFL, and climate anxiety

    Wildfire Emissions Are Skyrocketing

    Current conditions: Fire weather in California has prompted intentional power cuts for more than 5,000 PG&E customers • Large parts of central and northern Italy are flooded after heavy rains • The eastern U.S. will see “tranquil and near seasonable” weather this weekend.

    THE TOP FIVE

    1. Forest fire CO2 emissions have skyrocketed since 2001

    Carbon emissions from forest fires have risen by 60% in two decades, according to a new study published in the journal Science. “We had to check the calculations because it’s such a big number,” Matthew Jones, the lead author of the report and a physical geographer at the University of East Anglia in England, toldThe New York Times. “It’s revealed something quite staggering.” The research specifically links this trend to climate change, which is creating hotter, drier conditions. Emissions from boreal forest fires in Canada and Siberia saw a particularly large increase between 2001 and 2023. In one type of boreal forest, emissions nearly tripled. The rise in emissions from forests – which normally serve as large carbon sinks – “poses a major challenge for global targets to tackle climate change,” the researchers said.
