Los Angeles is sweating through another brutal summer, but the biggest shakeup in the city's climate defenses just happened behind closed doors.
The Bass administration quietly ousted Marta Segura, the city’s first chief heat officer and director of the Climate Emergency Mobilization Office (CEMO). There was no press conference. No public acknowledgment. Activists and City Council members only found out weeks after the decision was made. Discover more on a similar topic: this related article.
It is a bizarre, counterintuitive move for a city that routinely breaks temperature records and is staring down a future of longer, deadlier heatwaves. It looks less like a strategic transition and more like a systematic dismantling of LA’s climate resilience infrastructure.
Shuttering the Defense Against Rising Temps
When Los Angeles created the chief heat officer role in 2022, it was hailed as a forward-thinking move. LA was one of only a handful of cities worldwide to dedicate a specific position to combatting the silent killer of extreme heat. Segura's job wasn't just a bureaucratic title; it was meant to coordinate emergency responses, map out cooling centers, and figure out how to protect vulnerable communities. More journalism by BBC News explores comparable views on this issue.
Now, that entire apparatus is on life support.
- Staffing ghost town: CEMO, which once had six staff members pushing forward climate equity policies, has been hollowed out to just one single employee.
- The budget axe: Mayor Karen Bass previously floated a proposal to eliminate the climate emergency office entirely to patch up a massive city budget shortfall. While the City Council fought back and blocked the outright deletion of the office, the administration achieved a similar result through quiet attrition and targeted firings.
The mayor's office insists they are committed to appointing a "dynamic new chief heat officer" to develop a Heat Action and Resilience Plan. But firing the person holding the wheel right as summer peaks is a dangerous way to show commitment.
The Politics of a Silent Killer
Extreme heat doesn't create dramatic news footage like a wildfire or an earthquake, but it kills more Americans than any other weather-related disaster. In a sprawling metropolis like LA, heat is also a stark indicator of economic inequality. Wealthier neighborhoods enjoy dense tree canopies and reliable air conditioning. Working-class areas face the urban heat island effect, baking under asphalt with little relief.
Segura's background in public health meant she approached heat as an equity crisis. By dismantling her team, the city loses institutional memory right when it needs it most.
The political timing is also messy. City Councilmember Nithya Raman, who is challenging Bass in the upcoming mayoral primary, immediately called out the administration's move. Raman is pushing for an even more expansive approach to climate infrastructure, emphasizing that LA needs aggressive tree canopy expansion and real shade strategies before major global events hit the city.
If the city cannot manage its climate staff during a standard July heatwave, how is it going to protect millions of tourists and residents when the world arrives for the Olympics?
Where Los Angeles Goes From Here
Bureaucratic reshuffling won't lower the temperature on the pavement. The city needs immediate accountability and actual strategy, not vague promises of a future hire. To keep Angelenos safe, the administration must prioritize these immediate steps:
Demand Transparency on the Climate Budget
The public and neighborhood councils need to pressure City Hall to fully fund the remaining positions within CEMO. A city with a billion-dollar budget deficit shouldn't be balancing its books on the backs of environmental health programs.
Accelerate the Cool Spots Map
Until a new chief heat officer is vetted and confirmed, neighborhood groups should utilize and distribute existing city resources like the Cool Spots LA map. This tool helps residents locate hydration stations, splash pads, and air-conditioned libraries during peak heat hours.
Push for Local Shade Infrastructure
Don't wait for a centralized city plan to trickle down. Residents can directly lobby their specific council districts to fast-track bus shelters and native plant initiatives that alleviate extreme exposure in high-risk neighborhoods.
The Bass administration needs to realize that a chief heat officer isn't a luxury role you cut when times get tough. It's essential infrastructure for a warming city. Quietly clearing out the climate office leaves LA exposed during the hottest months of the year.
