The Brief

Climate change is expensive, deadly and preventable, according to the new National Climate Assessment, the most sweeping, sophisticated federal analysis of climate change compiled to date.

Released every five years, the National Climate Assessment is a congressionally mandated evaluation of the effects of climate change on American life. This new fifth edition paints a picture of a nation simultaneously beset by climate-driven disasters and capable of dramatically reducing emissions of planet-warming gasses in the near future.

This is the first time the assessment includes standalone chapters about climate change's toll on the American economy, as well as the complex social factors driving climate change and the nation's responses. And, unlike past installments, the new assessment draws heavily from social science, including history, sociology, philosophy and Indigenous studies.

The new approach adds context and relevance to the assessment's robust scientific findings, and underscores the disproportionate danger that climate change poses to poor people, marginalized communities, older Americans and those who work outdoors.

"Climate change affects us all, but it doesn't affect us all equally," says climate scientist Katharine Hayhoe, one of the authors of the assessment. But threaded throughout the report are case studies and research summaries highlighting ways "climate action can create a more resilient and just country," she says.

This is also the first time the National Climate Assessment will be translated into Spanish, although the Spanish-language version won't be available until the spring, according to the White House.

The National Climate Assessment is extremely influential in legal and policy circles, and affects everything from court cases about who should foot the bill for wildfire damage, to local decisions about how tall to build coastal flood barriers. "It really shapes the way that people understand, and therefore act, in relation to climate change," says Michael Burger, the director of the Sabin Center for Climate Change Law at Columbia University.

Hundreds of scientists from universities, industry, and federal agencies contributed to the report. They reviewed cutting-edge research published since the last report and contextualized it in decades of foundational climate research.

The fifth edition of the assessment arrives as millions of Americans are struggling with the effects of a hotter Earth. Dramatic and deadly wildfires, floods and heat waves killed hundreds of people in the United States in 2023.

And, while federal spending on renewable energy and disaster preparedness has increased, the U.S. is also investing in new fossil fuel infrastructure that is not compatible with avoiding catastrophic warming later this century.

Here are the three big takeaways from the Fifth National Climate Assessment. More information about the specific effects of climate change in your area can be found in the assessment's regional chapters.

Climate change makes life more expensive

Food, housing, labor – it all gets pricier as the Earth heats up, according to the National Climate Assessment.

Climate-driven weather disasters, like heat waves, floods, hurricanes and wildfires, are particularly expensive. They destroy homes and businesses, wreck crops and create supply shortages by delaying trucks, ships and trains. Such disasters make it more likely that families will go bankrupt, and that municipal governments will run deficits, the authors note.

Weather-related disasters in the U.S. cause about $150 billion each year in direct losses, according to the report. That's a lot of money – roughly equal to the annual budget for the Energy Department – and it's only expected to go up as the Earth gets hotter.

And that's all before factoring in the less obvious or tangible costs of climate change. For example, healthcare bills for people who are sicker because of extreme heat, or have respiratory illness brought on by breathing in mold after a flood. Exposure to wildfire smoke alone costs billions of dollars a year in lost earnings, the assessment notes – a burden that falls disproportionately on poor people who work outdoors.

"The research indicates that people who are lower income have more trouble adapting [to climate change], because adaptation comes at a cost," says Solomon Hsiang, a climate economist at the University of California, Berkeley and a lead author of the assessment.

For example, one of the simplest ways to adapt to severe heat waves is to run your air conditioner more. But "if people can't pay for it, then [they] can't protect themselves," explains Hsiang.

And the hotter it gets, the more profound the economic harm, assessment warns. Twice as much planetary warming leads to more than twice as much economic harm, the assessment warns.

Climate change makes people sick and often kills them

Since the previous NCA was released five years ago, the health costs of climate change have gone from theoretical to personal for many Americans.

The most obvious risk? Extreme weather, particularly heat, says Mary Hayden, the lead author of the chapter examining human health. Heat waves have become hotter, longer, and more dangerous, and they're hitting areas that aren't ready for them–like the "record-shattering" heat dome that descended on the Pacific Northwest in 2021 and caused hundreds of deaths.

But it's not just heat. Wildfire smoke can send people thousands of miles from the fires to hospitals with respiratory problems and heart disease complications. Hurricanes can disrupt people's access to healthcare: when a clinic is flooded or people are displaced, for example, kidney patients can't get dialysis treatment.

In most cases, the people who bear the brunt of the disasters are those already at risk: poor communities, communities of color, women, people with disabilities, and other marginalized groups. Temperatures in formerly redlined neighborhoods in cities across the country can soar nearly 15 degrees Fahrenheit hotter than wealthier areas just blocks away, putting residents at much higher risk of heat exposure.

The assessment also homes in on research tracking less-obvious health impacts. Living through climate disasters, for example, can leave lasting emotional scars. "We're not just talking about [people's] physical health–we're talking about their mental health. We're talking about their spiritual health. We're talking about the health and well-being of communities which are being affected by this," Hayden says.

That means recognizing the long-term effects on communities like Paradise, California, where people still deal with deep emotional trauma five years after their town burned in the 2018 Camp Fire. The report also flags the growing emotional toll on children and young people, for whom anxiety about the future of the planet is bleeding into all parts of their lives.

Climate change threatens people's special, sacred places and practices

The places, cultural practices, and traditions that anchor many communities are also in flux because of climate change.

Fishing communities are seeing their livelihoods shift or collapse. The Northeast's iconic lobster fishery, the single most economically valuable in the country, has withered as marine heatwaves sweep through the regional seas. Shrinking snowpack and too-warm temperatures are interrupting opportunities for beloved recreational activities, like skiing or ice fishing.

Indigenous communities are being forced to adjust to new climate realities, which are disrupting traditional food-gathering traditions. In Palau, a monthly tradition of catching fish at a particularly low tide has been upset by sea level rise, which keeps water levels too high to trap fish in the historically-used places. Sea level rise is also forcing coastal communities to re-think their very existence, pulling apart the social fabric that has developed over generations.

But many communities – Indigenous people, farmers and fishers, groups that have lived tightly connected to their environments for a long time – have deep stores of resilience from which to draw, says Elizabeth Marino, a sociologist and the lead author of the chapter on social transformations. "There is quite a lot of wisdom in place to adapt to and even mitigate climate change," she says. "It allows people to come up with solutions that fit the lives that they lead, and that's also a place of hope."

The fixes to climate change can make Americans' lives better

The fifth assessment lays out a stark picture of the climate challenges the U.S. faces. Keeping planetary warming to "well below" 2 degrees Celsius (3.6 degrees Fahrenheit), the goal of the international Paris Agreement, will require immediate, enormous cuts to fossil fuel emissions in the U.S and beyond. Keeping warming below 1.5 degrees Celsius (2.7 degrees Fahrenheit), an ambitious target written into the Agreement, will be even harder, the report says.

But it also points out many successful efforts underway to adapt to the new reality and to prevent worse outcomes.

"It's not the message that if we don't hit 1.5 degrees, we're all going to die," says Hayhoe. "It's the message that everything we do matters. Every 10th of a degree of warming we avoid, there's a benefit to that."

Addressing fossil fuel-driven climate change can also help people live healthier lives, stresses J. Jason West, the lead author on a chapter on air quality. Dialing back fossil fuel emissions would help prevent further climate change and also lessen the kinds of air pollution most harmful to human health." There really is a lot of opportunity to take action that would resolve both of those problems at the same time," West says.

There's been a subtle shift in the report's perspective since the last one, says Candis Callison, a sociologist and author of the report. There's now a clear acknowledgement, developed through years of rigorous research, that the fossil fuel-powered society the U.S. built over generations was profoundly unjust. Many pollution-producing coal or gas power plants were sited in communities of color rather than white communities, affecting people's health outcomes for generations. And decisions about land and water use for energy extraction often excluded tribal communities, with consequences still playing out today.

The transition forward can look different, she says. "Climate change actually provides us with an opportunity to address some of those inequities and injustices–and to respond to these impacts," Callison says. "That's really a powerful thing."

A federal judge has ordered Los Angeles to pay more than $1.8 million in attorneys’ fees and costs to the L.A. Alliance for Human Rights and other organizations that sued the city over what it deemed an inadequate response to the homelessness crisis.

The city is appealing the decision.

The details

L.A. Alliance is a group of business owners and residents who sued the city and county of Los Angeles in 2020 in an effort to push both governments to provide more shelter to unhoused people in the region.

The city of L.A. settled with the plaintiffs in 2022, and U.S. District Judge David O. Carter is overseeing the city’s progress in keeping up with the terms of that agreement. The judge found the city breached its agreement in multiple ways in a ruling last summer.

Specifically, the judge found that the city did not provide a plan for how it intends to create 12,915 shelter beds, as promised, by 2027. The court also found the city “flouted” its responsibilities by failing to provide accurate, comprehensive data when requested and did not provide evidence to support the numbers it was reporting, according to court documents.

In addition to $1.6 million in attorneys’ fees and $5,000 in costs to L.A. Alliance, Carter awarded about $200,000 in fees and $160 in costs to the Los Angeles Catholic Worker and Los Angeles Community Action Network.

The organizations are considered “intervenors” in the suit, representing people experiencing homelessness on Skid Row. Their attorneys include those from the Legal Aid Foundation of Los Angeles.

Why it matters

In his order, released Tuesday, Carter compared the recent award to the millions of taxpayer dollars city officials agreed to pay an outside law firm representing L.A. in the settlement.

Carter wrote in the order that the attorneys' fees and costs to L.A. Alliance and others “is reasonable, especially in light of the approximately $5.9 million that the City’s outside counsel is charging.”

LAist’s housing and homelessness coverage was cited several times in the order.

“It has fallen to plaintiff, intervenors, and journalists to point out the deficiencies in the city’s reporting,” Carter wrote, referring to data the city is required to report to the court as part of the settlement.

“Plaintiff and intervenors must be compensated for this,” he said.

The city’s response 

Attorneys representing the city filed a notice of appeal with the U.S. District Court in Los Angeles on Thursday.

L.A. City Attorney Hydee Feldstein-Soto’s office did not respond to LAist’s requests for comment by phone or email.

Shayla Myers, senior attorney with the Unhoused People's Justice Project at the Legal Aid Foundation of Los Angeles, told LAist the intervenors participated in the case without compensation “because it's incredibly important given what is at stake in these proceedings that unhoused folks have a voice.”

Matthew Umhofer, an attorney for L.A. Alliance, told LAist he’s thrilled the court is imposing accountability on the city, including sanctions for violating the settlement agreement. But Umhofer said he’s saddened that L.A. Alliance is going to have to keep fighting to hold the city to its promises.

“The obvious city strategy here is hire a big, good law firm to fight on absolutely every front in hopes that the plaintiffs, the intervenors or the court will ultimately give up trying to hold the city accountable,” he said.

What's next

The parties are scheduled to appear in federal court in downtown L.A. on Monday, when a hearing will resume to determine whether the judge will hold the city of Los Angeles in contempt of court.

Carter has said in documents that he’s concerned “the city has demonstrated a continuous pattern of delay” in meeting its obligations with court orders under the settlement and that the “delay continues to this day.”

Every January, the open-air downtown food fair reopens after its winter break and announces new additions to its carefully selected group of regular vendors.

This year’s new vendor class demonstrates the resilience of L.A.'s independent food scene, ranging from a Grammy-nominated producer's Persian-influenced pizza to Southern fried fish celebrating Black American culinary traditions, to an LAist 2025 Tournament of Cheeseburger heavyweight contender.

The reopening also marks the start of Smorgasburg LA's 10th anniversary year, and will feature 41 returning vendors, who've helped build the regular event into a fun, family-friendly opportunity to try new, often cutting-edge food you may not be familiar with.

Doors open from 10 a.m. to 4 p.m. at DTLA’s The Row, with free entry and free parking for the first two hours.

A new year

General manager Zach Brooks said this is his favorite time of year. "We add the new vendors at the beginning of the new year, everyone's excited."

Vendors apply through Smorgasburg's website, and the team meets with every applicant to taste their food before acceptance. Brooks said it's not a vetting process like "Shark Tank" but rather a matter of seeing if it's a good fit. Competition remains fierce, with many more applicants than available spots.

"I think it's just a testament to L.A. and the resilience of people who love this business and have a passion for it, and are going to continue to persevere and start their businesses and want to be out there selling food," Brooks said.

Here are a few highlights:

Viral orange chicken sandwich 

Long Beach-based Terrible Burger becomes Smorgasburg's new permanent burger vendor after standout appearances at LAist's Tournament of Cheeseburgers and the market's rotating Smorgasburger Stand. The smashburger pop-up, run by husband-and-wife team Nicole and Ryan Ramirez, specializes in burgers that draw from pop culture and global influences. They've made waves with a Korean barbecue burger topped with bulgogi barbecue sauce and a viral orange chicken sandwich, previously available only at their Tuesday night residency at Long Beach's Midnight Oil, making its L.A. debut Sunday.

"We have been big Smorgasburg fans for a really long time before we even started Terrible Burger. We would go to Smorgasburg on dates, just eat and hang out. And it was just always a little dream of, "oh, what if we ever sold food here?" Nicole Ramirez said.

Crispy fried snapper and thick-cut fries 

Orange County-based Hot Grease, run by Asha Starks, is among four vendors graduating from residencies to permanent status. The Southern fried fish pop-up celebrates Black American history through food that honors Starks' family heritage.

"Folks often forget that there are Black folks in Orange County. My family came to Orange County during the second wave of the Great Migration, and they settled in Santa Ana... my food is very cultural. And the story, I feel like, is just as important to highlight," Starks said.

Hot Grease serves crispy buttermilk fried snapper with thick-cut fries and small-batch sauces like "Ill Dill" tartar. Honoring the fish fry's history as a site of mutual aid, Starks directs 3% of sales to the Potlikker Line, Hot Grease's reproductive justice mutual aid fund. For January, she's added fish and grits, black-eyed peas and collard greens.

Pizza with a Persian twist

Mamani Pizza, from the Grammy-nominated producer Farsi, part of the music production team Wallis Lane, started making Neapolitan-style pizzas at his West L.A. recording studio a year ago. What began as late-night pies for friends and artists became an underground hit. Most pizzas are traditional, but Farsi adds Persian touches like The Mamani, topped with ground wagyu koobideh, roasted Anaheim chilis, Persian herbs and pomegranate molasses.
