  • The city prepares for warmer and wetter climate
    Copenhagen, Denmark, is expected to receive 30% more rainfall by the end of the century. The city is responding with a massive long-term adaptation plan. Enghaveparken, pictured here, is part of that plan. The park was redesigned after a 2011 flood to be able to transform into a massive reservoir in the event of heavy rain.

Enghaveparken, pictured here, is part of that plan. The park was redesigned after a 2011 flood to be able to transform into a massive reservoir in the event of heavy rain.

    Topline:

    Europe is the fastest-warming continent, according to scientists from the United Nations and the European Environment Agency. Temperatures are increasing at twice the global average rate, leading to more fires and flooding. That means cities built centuries ago, including Copenhagen, Denmark, are racing to adapt.

    The background: As the planet warms, the atmosphere can hold more moisture, which can lead to more intense rainfall events. "The typical rule of thumb is that for 1 degree Celsius of warming, the atmosphere holds 7% more water," a climate scientist says.

    Copenhagen's plan: Meteorologists predict the city will receive 30% more rainfall by the end of this century. After a massive flood in 2011, city officials adopted a "Cloudburst Management Plan," a $1.3 billion public works project to complete 300 flood-mitigation projects over two decades. It includes tunnels to move rainwater under the city and "sponge parks" to soak it up.

    Why does it matter? The scale of the city's long-term climate adaptation planning has gained admirers among urban planners throughout the world, a city official says. In addition to penning a collaboration with New York City on climate adaptation, Copenhagen has also consulted with cities in South Africa, China, Germany and beyond on how they can build similar infrastructure to mitigate the increased flooding that comes with climate change. The key is "intense planning," the official says.

    COPENHAGEN, Denmark — Sometimes, a single storm can change a city. For Copenhagen, that storm hit on July 2, 2011.

    Climate Solutions Week

    Climate change shapes where and how we live. That's why NPR is dedicating a week to stories about solutions for building and living on a hotter planet.

    "It was over 100 millimeters of rain in a couple of hours. It fell directly on the city of Copenhagen," recalls Mark Payne, a climate researcher at the Danish Meteorological Institute.

    Sewers overflowed, and the streets filled with raw sewage, causing more than $1 billion in damage to property. Video from the weather event shows city streets transformed into waterways and passing city buses generating waves that broke against storefronts, while the rain persisted, relentless and torrential.

    In July 2011, Copenhagen was hit by a "cloudburst" — an extreme rain event. The storm dumped more than 5 inches of rain on the city in a few hours.

    Climate scientists like Payne call these storms "cloudbursts," or extreme rain events. As the planet warms, the atmosphere can hold more moisture, which can lead to more intense rainfall events.

    "The typical rule of thumb is that for 1 degree Celsius of warming, the atmosphere holds 7% more water," Payne says.

    Europe is the fastest-warming continent, according to scientists from the United Nations and the European Environment Agency. Temperatures are increasing at twice the global average rate, leading to more fires and flooding.

    In Copenhagen, meteorologists predict the city will receive 30% more rainfall by the end of this century. Just a year after the flood, city officials adopted a "Cloudburst Management Plan," a $1.3 billion public works project to complete 300 flood-mitigation projects over two decades.

    Tunnels beneath the city

    One of the plan's most high-profile projects is nearly complete: the Kalvebod Brygge Cloudburst Tunnel.

    To show it off, engineer Jes Clauson-Kaas carefully descends down nine stories of rickety scaffolding along the edge of a massive concrete hole bored into the earth.

    When he arrives at the bottom, he lifts his head and brings two fingers to his lips to produce a loud whistle, its screech echoing along the curved concrete walls above.

    "An opera singer's dream," he says, smiling.

    Clauson-Kaas is chief consultant for the Copenhagen waterworks utility HOFOR, which is overseeing the construction of the tunnel.

    As he walks the perimeter of a cathedral-sized vault that will soon be the pump room, he motions to a hole in the wall just above his head: It's the terminus of a tunnel that's nearly a mile long and 10 feet in diameter and can hold 10,000 cubic meters of water, equal to the volume of four Olympic swimming pools. It's one of seven new tunnels dug under Copenhagen to hold excess rainwater during cloudburst events.

    Clauson-Kaas explains how it works: Once the tunnel is full, he says, the pumps are switched on, "and they can simply suck out this water into the harbor."

    Collecting rain in 'sponge parks'

    Just blocks away from the Kalvebod Brygge tunnel is Enghaveparken, a century-old park that was redesigned after the 2011 flood to transform into a massive reservoir in the event of heavy rain.

    Today, neighborhood children play on a soccer field carved deep into the ground. The park itself is enclosed by a 3-foot-high concrete wall with gates that automatically emerge from the ground, sealing the park so that it can hold floodwater.

    Storing rainwater on the surface makes more sense than expanding the sewer system, says Jan Rasmussen, director of climate adaptation for the city of Copenhagen.

    "You can't expand a pipe as easily as this area can be expanded," he says. "[It's] also much cheaper if we can use areas like this to store rainwater."

    Rasmussen says Copenhagen has transformed 20 green areas like Enghaveparken into what the city nicknames "sponge parks." When full, he says, Enghaveparken can hold 25,000 cubic meters of water. When it's not raining, a 2,000-cubic-meter storage tank underneath a rose garden in the park holds rainwater collected from the neighborhood's storm drains, used to irrigate the park's lawns, trees and flowers.

    People walk in a green park with lavender blooms in the foreground.
    Karens Minde Park in Copenhagen has built-in areas for rainwater retention. It's one of the hundreds of projects that Copenhagen is taking on to prevent damage from flooding.

    In addition to the sponge parks and cloudburst tunnels, Copenhagen has also just broken ground on a human-made island off its coast, named Lynetteholm. The island will house 35,000 people and protect the city against storm surges, another weather phenomenon happening more often here as the climate warms and sea levels rise. The island is expected to be finished by 2070.

    The scale of the city's long-term climate adaptation planning has gained admirers among urban planners throughout the world, says Rasmussen. In addition to penning a collaboration with New York City on climate adaptation, he says, Copenhagen has also consulted with cities in South Africa, China, Germany and beyond on how they can build similar infrastructure to mitigate the increased flooding that comes with climate change.

    "The trick to make all of this a success," says Rasmussen, "is intense planning."

    Evidence of Copenhagen's plan to fight flooding can be seen all over the city — like this catchment basin in a green space along Scandiagade street.

  • Impact on community after immigration crackdown
    Afghan evacuees sit on a bus at the U.S. air base in Ramstein, Germany, on Aug. 26. Ramstein Air Base, the largest U.S. Air Force base in Europe, has hosted thousands of Afghans.

    Topline:

    The Trump administration’s sudden freeze on all visa and asylum decisions for Afghan immigrants has left many of them in Orange County — one of the country's largest hubs for Afghans — in limbo. Local groups are preparing to support the immigrants even as they await clarification from federal authorities.

    Why it matters: California is home to the nation’s largest concentration of Afghan immigrants, many of them now grappling with the Trump administration’s abrupt visa and asylum freeze.

    Read on ... to learn more about the Afghan population in Orange County and guidance from one O.C. immigration official on what could come next.

    California is home to the nation’s largest concentration of Afghan immigrants, many of them now grappling with the Trump administration’s abrupt visa and asylum freeze.

    Friday’s announcement by the White House followed the fatal shooting of a National Guard member in Washington, D.C. a couple days earlier by a suspect who had immigrated from Afghanistan.

    In Orange County, where many Afghans have settled as their immigration applications pend, local officials are gearing up to help them navigate the change, even as guidance is scant from U.S. Citizenship and Immigration Services.

    Jose Serrano, director of Orange County's Office of Refugee and Immigrant Services, said the goal is to provide the “most up-to-date information so they can continue on towards their pathway towards citizenship here in the United States.”

    “The Afghan population in Southern California, specifically in Orange County, is one that is really important to the DNA of who we are,” Serrano said. “Let's continue to stay together and strong and reimagine a place for belonging for everyone.”

    As they await more information, Serrano advised visa and asylum seekers to:

    • stay on top of updates from USCIS and the Department of Homeland Security
    • contact their local office of immigrant and refugee affairs
    • connect with organizations that work closely with immigrant and refugee populations such as resettlement agencies and legal aid groups

    The pull of OC

    Nearly 200,000 Afghans are in the U.S., with 39% of them residing in California, according to the Migration Policy Institute.

    Hundreds of Afghan households have settled in Orange County, Serrano said, placing it alongside the San Diego and Sacramento areas as one of the state’s hubs for Afghan immigrants.

    Serrano said a big draw for immigrants to Orange County is Little Arabia in Anaheim, a regional destination for Middle Eastern food, culture, and community life.

    Serrano, who spent more than a decade working with immigrants at World Relief Southern California and the state's refugee programs bureau, said entering Afghan homes means being offered large meals. One family had prepared a whole feast for a Time Warner cable worker, he recalled.

    “They didn't understand why that person couldn’t stay to dine with them,” he said. “That’s the type of people that are here in Orange County, folks who are so committed to being a part of civic engagement, to connecting alongside other communities.”

    Visa applications in limbo

    Serrano said many of the Afghans who resettled in the county are Special Immigrant Visa holders, a program created for Afghan nationals who helped the U.S. government during the war in their home country.

    That program has now been frozen by the State Department.

    Serrano said immigrants who entered the U.S. as refugees and have since become green card holders could see their cases reopened.

    Joseph Edlow, who leads USCIS, said the new immigration measures will last until “we can ensure that every alien is vetted and screened to the maximum degree possible.”

    For Serrano, the current screening process is rigorous and involves multiple organizations aside from USCIS such as the U.S. Department of Justice, the F.B.I. and counterterrorist organizations.

    Applicants undergo health screenings and multiple fingerprinting appointments, he said.

    “They're constantly doing an assessment to verify that you are a good standing citizen,” Serrano said. ““One of the things that I think we should be very proud of within the United States is that there is an in-depth screening process for anyone who is seeking a protection.”

  • Four dead and 10 wounded in banquet hall shooting

    Topline:

    Four people were killed and 10 wounded in a shooting during a family gathering at a banquet hall in Stockton, sheriff's officials said Saturday.

    Details: The victims included both children and adults, said Heather Brent, a spokesperson for the San Joaquin County sheriff's office.

    What's next: Early indications "suggest this may have been a targeted incident," Brent said during a news conference at the scene. Local officials said the suspected shooter has not been caught and pleaded with the public for help. Detectives were still working to identify a possible motive.

    STOCKTON, Calif. — Four people were killed and 10 wounded in a shooting during a family gathering at a banquet hall in Stockton, sheriff's officials said Saturday.

    The victims included both children and adults, said Heather Brent, a spokesperson for the San Joaquin County sheriff's office. Early indications "suggest this may have been a targeted incident," Brent said during a news conference at the scene.

    Local officials said the suspected shooter has not been caught and pleaded with the public for help. Detectives were still working to identify a possible motive.

    "If you have any information as to this individual, reach out immediately. If you are this individual, turn yourself in immediately," San Joaquin County District Attorney Ron Freitas said during a news conference.

    The shooting occurred just before 6 p.m. inside the banquet hall, which shares a parking lot with other businesses. Stockton is a city of 320,000 about 40 miles (64 kilometers) south of Sacramento.

    "Families should be together instead of at the hospital, standing next to their loved one, praying that they survive," Mayor Christina Fugazzi said.

    Authorities did not immediately provide additional information about the conditions of the victims. Officials said earlier that several were taken to hospitals.

  • Rise of a new generation in House races

    Topline:

    In a handful of California’s deep blue districts, an intra-party battle over the future of the Democratic Party is brewing in the wake of grim losses during last year’s presidential race.

    Why now: In Sacramento, Napa County and Los Angeles, three younger challengers are arguing that Democrats need to give voters fresh faces with bold new ideas to energize the party’s base, rather than aging incumbents who are entrenched more in Washington insider culture than in their districts.

    The backstory: The recent retirements of Nancy Pelosi and other longtime House Democrats have led to more calls for aging members to pass the torch. Incumbents argue their experience is crucial as the executive branch is upending the balance of power in Washington.

    California’s battleground House districts might get the lion’s share of national attention for their role in deciding which party rules Congress’s lower chamber.

    But in a handful of California’s deep blue districts, an intra-party battle over the future of the Democratic Party is brewing in the wake of grim losses during last year’s presidential race.

    In Sacramento, Napa County and Los Angeles, three younger challengers are arguing that Democrats need to give voters fresh faces with bold new ideas to energize the party’s base, rather than aging incumbents who are entrenched more in Washington insider culture than in their districts.

    “Status quo politics isn’t going to protect our communities,” said Sacramento City Councilmember Mai Vang, 40, who is running against 10-term Rep. Doris Matsui, 81. “We need leaders who can meet the moment. And that’s why I decided to step into the ring.”

    Vang is the first formidable primary challenge that Matsui has faced in the two decades since the congresswoman won her late husband’s seat in 2005. Former Rep. Bob Matsui held that seat for 26 years prior.

    Two other senior California congressional Democrats have also attracted primary challengers. Rep. Mike Thompson, 74, of Napa County, a Vietnam veteran vying for his 15th term, faces a challenge from Eric Jones, 34, a former San Francisco venture capitalist.

    And farther south, former Obama and Biden White House climate aide Jake Levine, 41, is challenging Rep. Brad Sherman, 71, of Los Angeles, who is seeking his 16th term. All three challengers have vowed not to take corporate PAC money as their incumbent opponents do.

    Around California and across the country, younger challengers argue that Democratic incumbents in safe districts take their seats for granted since they so rarely receive serious challenges. That false sense of security, Vang said, results in out-of-touch members who have fewer incentives to show up in their districts and talk to voters.

    Part of meeting the current moment, Vang argues, means taking “bold and courageous” positions on important issues, such as speaking out forcefully against the Trump administration’s immigration enforcement tactics.

    Vang said she wants Matsui to more strongly condemn immigration raids that have torn Sacramento families apart and violated residents’ due process rights. She was disappointed that Matsui’s denunciations centered around the unsanitary conditions of the John E. Moss federal building, where advocates said detainees were being held without access to proper hygiene, rather than on the separation of families and indiscriminate detentions.

    “For the past several months we’ve had neighbors, people in our community that have been kidnapped by ICE, taken by ICE, and Doris hasn’t spoken up against that at all,” Vang said. “And especially as someone who was born in the internment camps, I would think she would be on the front lines to speak out on the issues.”

    Matsui was born in the Poston War Relocation Center internment camp in Arizona, where her parents were incarcerated during World War II.

    “That’s nonsense,” said Roger Salazar, a campaign spokesperson for Matsui, noting local news coverage of Matsui’s statement against an immigration raid on a South Sacramento Home Depot and her attempt to access an ICE detention facility. “She needs to watch the news.”

    Matsui in October hosted a rare in-person forum only after constituents spent months calling on her to meet with them. Angry Sacramentans also hosted an empty-chair town hall in March to highlight Matsui’s absence, not even two weeks after House Democrats did a nationwide blitz of showing up in Republican districts to prove a similar point.

    Some senior leaders are sticking around

    Calls for generational change within the Democratic Party, while not new, have increased significantly as the party works to find its footing after 2024. The dynamic played out first in internal House leadership races earlier this year, where younger members like Rep. Robert Garcia of Long Beach leapfrogged more senior colleagues to lead powerful committees.

    Rep. Thompson, Matsui’s congressional counterpart in neighboring Napa County, said his constituents have stopped him in public and asked him to run again.

    “I can’t tell you how many times I had people tell me, ‘I sure hope you’re gonna stick around. We need you more now than ever,’” Thompson told CalMatters. “No one’s asked me to retire. No one has suggested that I’ve been there too long. And everyone knows that not only am I capable, but I’m in good shape.”

    In Sacramento, Vang, the eldest of 16 children whose Hmong parents came to the United States as refugees, said she has the utmost respect for the Matsuis and their long history of service.

    Still, she has called on Matsui to follow the examples of House Speaker Emerita Nancy Pelosi — who announced last month that she would retire next year and not seek reelection to a 21st term in Congress — and Rep. Nydia Velazquez of New York, who told The New York Times that “now is the right moment to step aside and allow a new generation of leaders to step forward.”

    But Matsui remains steadfast that she has much more work to do in Congress, such as overseeing groundbreaking for Sacramento’s new I Street bridge and securing federal funds for flood prevention and wildfire recovery, and said she will stay in the race. She emphasized that the deep relationships she’s built over 20 years in Washington are critical to her ability to deliver on those projects.

    “It’s important to not only have advocates, but have people who understand that once you’re in Congress, you have to learn how to govern, too,” Matsui said. “We cannot just throw everything out and start over again.”

    As for Vang’s intra-party primary challenge, Matsui said anyone is “perfectly free” to run against her at any time. “I’m fine with that. This is our democracy. This is America.”

    But she insisted that her record would reinforce to voters how hard she works.

    “I show up every single day working for Sacramento,” Matsui said, “whether it’s in Sacramento or in D.C.”

    The risk of Dem-on-Dem challenges 

    One risk of primarying veteran members of Congress is the loss of institutional wisdom, said Gale Kaufman, a Sacramento-based Democratic strategist, particularly with the Trump administration testing the limits of the law and boundaries of power.

    “Especially when you’re up against stuff like this, which we’re not familiar with, breaking every norm you could possibly imagine,” Kaufman said, “having some of those people around is not a bad thing.”

    Even among younger Democrats, there’s not wide consensus that incumbents are out and young challengers are automatically in. Evan Cragin, president of the Sacramento County Young Democrats, echoed Kaufman’s point that a blanket policy of “vote out all incumbents over a certain age” could be counterproductive.

    While the Young Democrats have yet to endorse anyone in the congressional races, Cragin said he is personally conflicted about who to support.

    “I don’t know who I’m going to vote for,” Cragin said. “It’s nice to have a strong member at the moment, but also, there is part of me that wants to make sure we support our younger members. And Councilmember Mai Vang is a very strong challenger. She’s very community oriented.”

    Those who support intra-Democratic challenges argue that they drive important dialogue and force candidates to clearly articulate their ideas and earn voters’ trust, rather than taking their support as a given. Incumbent Democrats across the country could benefit from primary challenges as the party soul searches, said Alex Niles, vice president of political affairs for the Sacramento County Young Democrats.

    “We need to have a reckoning and figure out, ‘What does it mean to be a Democrat? What do we stand for? What do people want and who are we serving?’” Niles said.

    Unsurprisingly, many incumbents and political strategists disagree, denouncing intra-party primaries as expensive distractions that deplete safe members’ fundraising that could otherwise support colleagues in more vulnerable districts.

    “The circular firing squad in blue districts hurts our ability to win swing districts,” Rep. Sherman told CalMatters in an interview.

    Candidates in safe districts often support their more vulnerable colleagues to gain clout within the party, whether through direct transfers of campaign cash or by urging their donors to channel their contributions to more contested races. Sherman argues that a competitive intra-Democratic primary forces a safe incumbent to invest more in their own reelection rather than helping flip battleground seats. He repeatedly mentioned tight races in Iowa and Ohio that he views as critical to Democrats reclaiming the House.

    “What happens in swing seats may determine whether America’s a democracy,” Sherman said. “Democrats have got to win seats in Iowa, and we can’t do it unless the strong Democrats in Bel Air and Brentwood and Malibu are focused on Iowa.

    “It’s hard to get people in Brentwood to focus on Iowa if there’s a real race in Brentwood.”

    He added that while it matters which Democrat represents California’s 32nd Congressional District, the Los Angeles-area seat that he’s represented for almost 30 years, it’s “not life or death for our democracy.”

    Sherman’s challenger Levine, who outraised the congressmember last quarter and appears to be the frontrunner in a crowded field, agrees that Democrats need to flip GOP-held seats to reclaim control of the House. But at the same time, if their party wants to retain the majority and win back disaffected voters, Democrats need to prove they’re focused on lowering the cost of living and improving their quality of life, in addition to preserving democracy.

    After leaving Los Angeles to pursue a climate policy career in Washington, D.C., Levine moved back home earlier this year to help his mother after she lost her house — his childhood home — in the devastating Palisades Fire. He was frustrated by the disjointed local and state response to recovery, and he had hoped Sherman would step up and coordinate the response.

    “The things that people want to hear about, and the things that I’m trying to talk about, are the issues in the district,” he said. “Those issues really are not about the composition of the House. They’re not about Washington inside-the-beltway questions of power.”

    Instead, Levine wants to see his member of Congress answer the kinds of questions that families like his own think about every day — “Can I afford my rent? Can my kids stay in the same neighborhood where they grew up, and even in the same state, because it’s so prohibitively expensive?”

    The Stahl House, otherwise known as Case Study House #22, is on the market for the first time in its 65 year history

    Why it matters: The mid-century modern home in Hollywood Hills has come to embody the post-war Los Angeles good life. It is also one of the most recognizable examples of West Coast modernism.

    Why now: The house has been with the same family since its completion. But after caring for it for more than 6 decades, the Stahl children are looking for the house's next steward.

    Read on... For the fascinating history of the Stahl House, find out why its original moniker is Case Study House #22, and see the photographs that have made the hilltop home a revered landmark

    A quintessential piece of Los Angeles history — a jaw-dropping mid-century modern of glass, steel and seemingly all skies soaring high above the Hollywood Hills — is up for sale.

    Asking price: $25 million.

    The Stahl House, otherwise known as Case Study House #22, has stayed with the same family since it was built in 1960.

    "After 65 years, our family has made the heartfelt and very difficult decision to place the Stahl House on the market," wrote the Stahl children, Bruce Stahl and Shari Stahl Gronwald.

    The 2,200 square foot home at 1635 Woods Drive has been preserved meticulously, funded in part by proceeds from open house tours of the space.

    "This home has been the center of our lives for decades, but as we’ve gotten older, it has become increasingly challenging to care for it with the attention and energy it so richly deserves," the Stahl children continued.

    And they are not just looking for a buyer — but a steward.

    "It is a passing of responsibility," the listing for the house reads. "A search for the next custodian who will honor the house's history, respect its architectural purity, and ensure its preservation for generations to come."

    The futuristic house with its stunning panorama and a swimming pool perched at the edge of nothingness has become one of the most recognizable and prized expressions of mid-century modern architecture in L.A. — how it came to be built was fueled by a similar spirit of experimentation and audacity.

    In 1945, the cutting edge Arts & Architecture magazine launched the "Case Study House" program to commission the era's biggest and most boundary pushing architects — Richard Neutra, Charles Eames and the like — to design and build within budget affordable, scalable homes for an exploding middle class after World World II.

    "Each house must be capable of duplication and in no sense be an 'individual' performance," editor John Entenza wrote in the announcement-slashed-manifesto.

    By its terminus in 1966, the program gave rise to 36 designs, of which 25 prototypes were built — mostly in and around the city — forging L.A. into an epicenter of West Coast modernism.

    Case Study Home #22

    One of them was Case Study Home #22 by Pierre Koenig, who as an architecture student at USC in the early 1950s was already making a name for himself, particularly for his use of steel.

    His student work caught the attention of Entenza, editor of Arts & Architecture, who later invited him to join the Case Study House program.

    The Stahl family home

    The Hollywood Hills home would be Koenig's second Case Study house — and his most well-known.

    The story began with Hughes Aircraft purchasing agent and former football player Buck Stahl and his wife Carlotta, who bought a small hillside lot overlooking the city for $13,500.

    The couple spent weekends putting up a wall around the property using broken concrete sourced from construction sites. Buck, the Stahl family said, had built a model of his dream house to take to architects — many of whom turned the job down because the lot was seen as undevelopable.

    Enter Koenig, who signed on for the challenge in 1957. A month before construction began in 1959, the project was christened Case Study House #22. The Stahl house was completed a year later, according to the Los Angeles Times, at a cost of nearly $38,000.

    The birth of cool

    With its sleek lines and inviting airiness, Case Study House #22 has come to embody the good life in post-war Los Angeles, an idea reinforced by its countless appearances in movies, TV shows and magazine spreads over the decades.

    But the photographs that started it all — elevating the home into the stuff of mythology — was taken by Julius Shulman, the man tapped to document the entire Arts & Architecture program, after charting an unlikely career photographing modernist architecture in L.A., starting with those designed by Neutra.

    Shulman shot the Stahl House in May 1960 shortly after its completion. In the most iconic shot of the series, two young women in white party dresses are sitting in the glass living room, conversing leisurely as the house dissolves into the shimmering sprawl below.

    "It was not an architectural quote-unquote 'photograph,'" said Shulman about the image in an interview for the Archives of American Art. "It is a picture of a mood.”
