Fires, Floods, and Federal Court

Current conditions: Deadly flooding in parts of the Midwest is forecast to worsen Tuesday before rivers crest midweek • Northern China remains in drought as the southern province of Guangdong suffers flooding, landslides, and mudslides • Western India braces for heavy rains.

THE TOP FIVE

1. SCOTUS takes on NEPA

The U.S. Supreme Court is due to close out its latest session this week (although decisions could stretch into July), and court- and climate-watchers are expecting it to issue a death blow to a legal precedent called the Chevron deference, which gave federal agencies wide latitude to interpret their mandates where the law was vague. More than 19,000 federal court decisions rest on Chevron as a binding precedent, according to the Center for American Progress, and ending it would add to the already hefty legal burden of defending climate regulations.

But wait, there’s more! On Monday, the court agreed to take up a case that could determine whether federal agencies can consider a project’s indirect emissions when evaluating its environmental impacts. The case concerns a proposed railway that would transport oil in northeast Utah, which had its approval from the Surface Transportation Board thrown out by a federal appeals court last year. The appeals court ruled that the agency’s environmental review failed to assess how the railway would affect future oil development, along with several other environmental considerations. A group of Utah counties say those impacts are beyond the agency’s obligations under the National Environmental Policy Act.

A decision by the Supreme Court, which is expected to hear arguments in the fall, has the potential to apply not only to railways but also to many other projects regulated by the federal government, including pipelines and shipping ports.

2. Midwest floods leave path of destruction

A railroad bridge connecting Sioux City, Iowa, and North Sioux City, South Dakota, collapsed late Sunday amid flooding in the Midwest that also put a Minnesota dam in “imminent failure condition,” officials said.

The bridge, owned by BNSF Railway, spanned the Big Sioux River, where the water was about 45 feet high as of Monday morning — surpassing the previous record by more than 7 feet.

Minnesota’s Rapidan Dam on the Blue Earth River suffered a “partial failure” on Monday after water breached the west side of the dam and washed away an Xcel Energy substation. The Blue Earth County Sheriff's Office said on Facebook that it doesn’t know whether the dam will hold but that “there are no current plans for a mass evacuation.”

3. A California utility bets big on enhanced geothermal

The enhanced geothermal startup Fervo, which uses techniques borrowed from fracking oil and gas to access heat below the earth's surface to generate electricity, said today that it had signed the “world’s largest” geothermal power purchase agreements. The two deals with Southern California Edison, a California utility, add up to 320 megawatts from the company's Utah site. California utilities are mandated by the state energy regulator to buy 1,000 megawatts of non-weather-dependent power with no greenhouse gas emissions, for which geothermal fits the bill. The power will start flowing, Fervo said, by 2026 and will be fully up and running by 2028.

4. Study: Extreme wildfires are multiplying

Extreme wildfires have doubled in intensity and frequency over the past two decades due to climate change, according to a new study. The research, published in the journal Nature Ecology & Evolution, used satellite data to measure the occurrence of particularly powerful wildfires between 2003 and 2023. It found that such extreme events increased 2.2-fold during that period, with six of the past seven years ranking among the worst.

The changes aren’t uniform across biomes: Temperate conifer forests and boreal forests, both of which are prevalent in North America, are among the hardest hit. A report released last fall by Democrats on the Senate’s Joint Economic Committee showed the staggering cost of the fires to the United States. Accounting for damage to timber stocks and watersheds, smoke damage, lost income, and diminished real estate value on top of the property and insurance costs, the report found that fires cost the U.S. as much as $893 billion per year.

5. Coal plants’ reliability is diminishing

Coal plants are becoming less dependable as they age, the North American Electric Reliability Corporation said in its 2024 State of Reliability report. Coal plants’ weighted equivalent forced outage rate — defined as as “the probability that a group of units will not meet their generating requirements because of forced outages or forced derates,” with more weight given to larger generating units — was about 12% in 2023, compared with an average of 10% between 2014 and 2022, Jack Norris, a performance analysis engineer with NERC, told reporters. Norris said most other generation sources “have remained within a percentile over the same period,” while coal’s outage rates have been on the rise, Utility Dive reported. Rising maintenance needs and pressure to accommodate variable energy sources are also “having a negative impact on these units’ reliability,” Norris said.

THE KICKER

Germany will likely stop using coal before 2038 “just due to the economic viability,” the country’s climate envoy said Monday.

What Happens After Chevron?

It’s a sad day for the regulatory state. On Friday, the Supreme Court struck down a 40-year-old precedent that deferred to agencies’ interpretations of their own mandates where the statutory guidance was incomplete or ambiguous, otherwise known as Chevron deference, after the losing side in the original case. Not only has it been cited in more than 19,000 federal opinions, it’s the one congressional aides — the ones actually writing the laws — are most familiar with, as Lisa Heinzerling, a professor of environmental law at Georgetown Law, told me.

“So there’s a way in which Congress has been relying on Chevron for decades, right?” she said. “If Congress banked on Chevron, banked on the idea that if they didn’t make things clear the agency would take care of it, then that reliance is not being honored.”

The Self-Fulfilling Prophecy of Climate Coverage

If you want to know why voters don’t consider climate change a priority, just look at how it was treated.

Advocates for televised presidential debates argue that they offer the best chance voters will have during the campaign to get an extended look at the candidates, beyond what they see in 30-second ads and 8-second sound bites. We can hear them defend their records as they critique their opponents, and answer tough questions from seasoned reporters about key issues. It’s a rare opportunity to delve deep into substance on important issues.

If only that were how televised debates actually turn out. The one exchange on climate change that occurred in Thursday’s meeting between Joe Biden and Donald Trump showed just how problematic a forum for voter education this is.

AM Briefing: A Distressing Debate

On Biden’s fumble, SCOTUS, and EV sales

Well That Was a Very Distressing Presidential Debate

Current conditions: Forecasters are keeping an eye on a weather system moving toward the Caribbean that could strengthen into a tropical storm • Heavy rains have rejuvenated dried-up lakes and lagoons in Chile • Severe storms could bring strong wind, excessive rain, and hail to parts of Europe over the next few days.

THE TOP FIVE

1. Biden squanders his climate moment at presidential debate

Well, last night’s first 2024 debate between President Biden and Donald Trump was “altogether distressing,” writes Heatmap’s Katie Brigham. And while climate was far from the main focus, the two candidates did have one notable exchange. Trump initially dodged a question about whether he would take action to slow the climate crisis, then briefly noted “I want absolutely immaculate clean water and I want absolutely clean air. And we had it. We had H2O.” Biden responded by criticizing Trump’s decision to pull out of the Paris Agreement. “I immediately [re]joined, because if we reach 1.5 degrees Celsius, at any one point, there’s no way back,” Biden said. “The only existential threat to humanity is climate change. And he didn’t do a damn thing about it.”
