Jewish institutions awaken to climate crisis, with hundreds pledging action
(JTA) — For a decade starting in 2002, Jennifer Laszlo Mizrahi devoted herself to pro-Israel advocacy. After that, the Jewish philanthropist and activist from Annapolis, Maryland, went all in to fight for disability rights, working in the field for the next decade. Now, Mizrahi is focused on climate change.
“Let me put it this way: In 2021, we donated to one climate organization, and in 2022, we donated to 17 of them,” Mizrahi said, referring to the small charity fund she runs with her husband, tech entrepreneur Victor Mizrahi. This year, the couple made their largest climate-related donation yet, sending a group of nine climate reporters to Israel to meet tech startups working on ways to reduce greenhouse gas emissions. Mizrahi and her husband have also begun commercially investing in such startups.
“I was hoping other people would solve it,” she said. “But the pace of the change is not nearly meeting the demand at the moment. I felt that even though I don’t know the subject, I’m just going to have to do it because I have kids and I don’t want this world to fall apart.”
Climate change has long ranked at or near the top of a list of issues concerning Jews in the United States, according to multiple surveys, and Jews have been heavily involved in the wider climate movement. But until recently, the issue had a marginal place on the agendas of Jewish communal organizations, which neglected climate even as the subject took on importance in the activism and policies of other religious communities and in the larger philanthropic world.
Mizrahi’s newfound emphasis on climate is an early example of a larger shift that is underway in Jewish philanthropy, a multibillion-dollar world made up of thousands of individual donors, charitable foundations and nonprofit organizations.
“It’s the beginning of what will become a more widespread focus among Jewish groups,” said Rabbi Jennie Rosenn, the founder and CEO of the Jewish climate group Dayenu. “We’re seeing an awakening to this as a profoundly Jewish issue, and awakening to the role that the Jewish community has to play in addressing the climate crisis.”
Scientists say that decisions regarding carbon emissions made in the next few years will affect life on Earth for thousands of years to come. The most recent warning came in March, when leading global experts with the Intergovernmental Panel on Climate Change published a new report, stating that “there is a rapidly closing window of opportunity to secure a liveable and sustainable future for all.”
The large Jewish populations living in the coastal United States are vulnerable to extreme storms, sea-level rise, severe heat and other weather disruptions — a situation dramatized in the recent Apple television series “Extrapolations,” in which a rabbi contends with rising sea waters infiltrating his Florida synagogue. Meanwhile, Israel is experiencing a slew of impacts from drought and floods to security threats tied regional climate-related instability.

The last few months have seen a flurry of new initiatives aimed at both greening Jewish institutions and directing collective action on climate.
In December, for example, Rosenn’s group published a report calculating that endowments of Jewish organizations, from family foundations to local federations, are invested in the fossil fuel industry to the tune of at least $3 billion. The report launched an ongoing campaign called All Our Might that urges Jewish leaders to withdraw these investments and put the money toward clean energy instead.
Meanwhile, many of the most prominent Jewish organizations in the country — representing local federations, Hillel chapters, summer camps, community centers, day schools and nearly every religious denomination — had already joined a new green coalition organized by another Jewish environmental group and were preparing to unveil pledges to do more in the fight against climate change.
The unveiling of the climate pledges happened in March, under the leadership of Adamah, a nonprofit created through the merger of two stalwarts of Jewish environmentalism, Hazon and the Pearlstone Center.
“Climate and sustainability have not been on the list of priorities for the vast majority of Jewish organizations; this coalition and these climate action plans reflect a deep paradigm shift and culture change moving forward,” Adamah CEO Jakir Mandela said at the time.
The commitments made by members of Adamah’s Jewish Climate Leadership Coalition include sending youth leaders to global climate summits, reducing emissions of buildings and vehicles and lobbying the federal government to pass climate policies.
More than 300 congregations and nonprofits have joined. For Earth Day, Adamah announced a million-dollar fund offering interest-free loans and matching grants to Jewish groups for projects to reduce their greenhouse gas emissions.
If any single event can be said to mark the debut of the climate issue as a top Jewish communal priority, it is probably the recent annual conference of the Jewish Funders Network, which took place in March in Phoenix, bringing together thousands of donors and charity executives.
For the gathering’s first event, before the formal opening of the conference, a group of participants went on a field trip to downtown Phoenix to learn about the local effects of the climate crisis. Far more people signed up than organizers anticipated, and with about 55 passengers, the tour bus chartered for the occasion reached capacity. Mizrahi, who was among the participants, said the trip was helpful as a networking opportunity for like-minded philanthropists.
“We wanted to expose them to how the existential threats posed by climate change are not long term, but are already here,” Yanklowitz said. “People down in the Zone are dying every summer from heat exhaustion and dehydration.”
Based on his debrief with the group afterward, Yanklowitz feels the trip left an impact on participants.
“I didn’t hear anyone say, ‘Oh, I’m changing my commitments.’ But I did get the sense that climate change was kind of abstract for many people, and that now it really hit home,” Yanklowitz said.
The rest of the conference featured multiple talks and gatherings dedicated to climate, including on the main stage, and an announcement that Birthright, which offers free trips to Israel for young Jews, was increasing its own climate activism with the help of a new donation.
In an interview, Ellen Bronfman Hauptman and Stephen Bronfman, children of Birthright founder Charles Bronfman, said their $9 million gift is meant to honor their father on the occasion of his 90th birthday, while also bringing Birthright more in line with the values of a new generation that is environmentally-minded.
Birthright organizers will use the funding to develop programming focused on climate that could, for example, expose participants to Israel’s clean tech scene. The money is also intended to help Birthright lower its own carbon footprint, potentially by switching to electric buses or adding more vegetarian meals.
The Bronfmans hope that Birthright’s significant purchasing power in Israeli tourism will nudge the industry toward more ecologically sustainable practices.
“To me, Birthright is like Walmart — everyone wants to do business with them,” Stephen Bronfman said. “They have the power to dictate terms to their service providers and affect the supply chain.”
The widespread interest in climate mobilization among Jewish groups comes after years in which the issue languished outside the mainstream. Rosenn, the head of Dayenu, who has attended about 15 conferences of the Jewish Funder Network, noticed a change this year.
“There used to be half a dozen people at a breakfast before the program talking about climate. And it wasn’t even climate, necessarily — it was the environment writ large,” she said.
The Jewish world is, in many ways, still lagging behind the larger climate movement. Divesting endowment funds from the fossil fuel industry, for example, is seen as a bold step among Jewish groups even though at least 1,590 institutions representing nearly $41 trillion in assets have already publicly committed to doing so, according to a website tracking such pledges. About a third of the groups on the list are defined as faith-based organizations, but only three are Jewish: Kolot Chayeinu, a congregation in Park Slope, Brooklyn; the Reform movement’s pension system; and the American Jewish World Service, a global justice group.

Adamah’s own climate plan doesn’t include a pledge to divest but only a promise that it will investigate the option of doing so for its endowment and employee retirement funds. Instead, the plan touts the group’s education and advocacy efforts, and focuses on reducing emissions at its retreat centers.
Adamah’s chief climate officer, Risa Alyson Cooper, acknowledged that Jewish community institutions have been “largely absent” from the divestment movement and said her group regards divestment as one of several required tools for addressing the climate crisis.
She said the Jewish community hit a milestone when 12 of the 20 founding members of Adamah’s climate coalition said in their climate plans that they would consider amending their financial practices. That was significant, she said, in light of the organizations’ complex and deliberate governing structures, which can make executing such changes onerous.
“While the Jewish community may have lagged behind in years past, we are catching up quickly,” Cooper said.
Such a shift would mark not only a milestone for Jewish climate activism but also a departure from how the Jewish community has historically done philanthropy, said Rabbi Rachel Kahn-Troster, executive vice president of the Interfaith Center on Corporate Responsibility.
She said wielding financial holdings for social impact has been a hallmark of advocacy by Christian groups. Last year, the Presbyterian Church (U.S.A.) opted to divest from fossil fuels in light of the climate crisis.
The Jewish community, meanwhile, has tended to act primarily through charitable donations. One of the reasons for the difference, she said, is that the Jewish community is much less centralized with communal assets spread across many endowments, making the actions of any single group relatively less impactful.
“Adamah had done some really important work to change individual behavior and grow people’s connections to the environment, but the bigger piece of bold collective action to fight the climate crisis was missing,” Kahn-Troster said. “The overall community is late to respond to the urgency of the problem. But I do think that the work of these organizations is very significant, so I’m excited to see it.”
Kahn-Troster’s historical view is informed by the legacy of her father, Rabbi Lawrence Troster, an environmental activist who had pushed for communal Jewish action on climate, and by the passion for climate justice displayed by her 15-year-old, Liora Pelavin, a member of the Jewish Youth Climate Movement, an arm of Adamah.
“Finding a meaningful Jewish space to do grassroots-level climate advocacy that many young people are demanding has been really important to Liora,” Kahn-Troster said.

Volatility, Hit Frequency, and RTP: Why the Number Casinos Advertise Is the Least Useful One
The return to player percentage looks clean as a casino data point. It gives players a neat number, usually around 94% to 97% for many online slots, and that number feels easy to compare. A 96.5% game appears better than a 95.2% game. The problem starts when players treat RTP as a forecast for their next 50 spins or one evening.
You may find the RTP listed on slot pages on a leading online casino in Ontario, but the number only tells part of the story. Two games can share the same RTP and create different sessions: one may return small wins often, while the other may drain a balance before one bonus round changes everything.
The RTP Trap
Return to player (RTP) measures the theoretical share of total wagers a game returns across a very large number of rounds. In plain terms, a 96% RTP slot returns about $96 for every $100 wagered in the long run. That does not mean one player who deposits $100 should expect $96 back.
The trap sits in the word “theoretical.” RTP comes from the game’s math model. It works across huge samples, not personal sessions. A player can finish far above that percentage, far below it, or with nothing left after a short run of poor results.
Is it useless then? No, RTP can still help. It gives a baseline cost of play. Lower-RTP games cost more on average than higher-RTP games. Still, once a game passes a reasonable threshold, the next question matters more: how does it distribute that return?
Hit Frequency: The Number That Shapes Session Feel
Hit frequency tells you how often a game produces a winning outcome. This often misleads players because any win can count. A spin that returns $0.10 on a $1 bet may still count as a hit, even though the player lost $0.90 in real terms.
A game can feel active because symbols connect often, sounds play, and the screen keeps celebrating small returns. The balance may still fall. In many modern slots, “win” does not always mean profit on the spin.
Hit frequency answers one practical question: how much silence can you tolerate? Some players dislike long dry spells. Others accept quieter sessions because they chase bonus rounds or larger payouts.
The educational site Get Gambling Facts gives a useful distinction: RTP concerns the percentage of money returned over time, while hit frequency concerns how often a machine stops on a winning combination.
Volatility: The Risk Label Players Need More Often
Volatility, also called variance, describes how unevenly a game pays. Low-volatility games tend to return smaller amounts more often. High-volatility games hold more value in rare events: bonus rounds, premium symbols, multipliers, or jackpots.
Here is where RTP becomes less useful on its own:
- A 96% low-volatility slot may give modest returns and longer play from the same balance.
- A 96% high-volatility slot may burn through funds quickly unless the player hits a strong feature.
- A progressive jackpot game may look exciting, but it often places more value on rare top prizes.
The same RTP can hide very different risk profiles. Players who ignore volatility often blame the casino or the game when the session follows its math design.

Why the Same RTP Can Feel So Different
Picture two slots with 96% RTP. Slot A pays small wins on many spins, has a modest top prize, and rarely creates dramatic balance swings. Slot B pays less often but offers a large max win and volatile bonus rounds. The advertised return matches, but the experience does not.
Slot A may suit a player who wants a slower bankroll drop and more regular feedback. Slot B suits someone who accepts sharper losses in exchange for a shot at a heavier payout.
A Better Way to Read a Slot Page
Most slot pages give players more clues than they notice. The trick is to read the details together rather than chase the highest percentage.
Start with RTP. If two games look similar, the higher number has better long-term value. Then check volatility. If the game uses terms such as high, very high, or extreme variance, lower your bet size or expect shorter sessions. Next, look at the paytable. A huge max win usually means the game saves a lot of its value for rare outcomes.
A sensible pre-play check looks like this:
- RTP: What is the average long-term return?
- Volatility: How rough can the session become?
- Hit frequency: How often will the game show any wins?
- Paytable: Where does most value sit?
To Conclude
Casinos advertise RTP because it looks objective, tidy, and easy to rank. Players should read it, but they should not give it more authority than it deserves. For long sessions, volatility may matter more than a small RTP difference. For comfort, hit frequency may explain the feel better than the payback rate.

Lahmeyer, pastor who says Antichrist will be Jewish, heads to Oklahoma GOP runoff
(JTA) — Jackson Lahmeyer, a pastor who supports Israel and believes the Antichrist will be Jewish, is headed to a runoff in his district’s Oklahoma congressional primary.
The Donald Trump-backed Lahmeyer will face off against Mark Tedford, a member of the state House of Representatives from Tulsa, in the August runoff to decide who will be the Republican candidate for Congress in Oklahoma’s 1st Congressional District.
The runoff will pit candidates with two very different approaches to politics, and Israel, against each other at a time when the Republican Party is divided on multiple lines. Lahmeyer is part of Trump’s MAGA movement, while Tedford is a more traditional conservative. Both men promote a hard line on immigration, but Lahmeyer’s rhetoric has been peppered with incendiary claims about efforts by Muslims to establish “sharia law” in the United States.
While both competitors are also evangelical Christians with training in ministry, Lahmeyer works as a pastor and preaches an end-times theology that includes an Antichrist with Jewish heritage. Lahmeyer is also a vocal supporter of Israel, in keeping with his Christian Nationalist outlook, while Tedford has made few if any public comments about Israel or the war in Gaza.
The two candidates pulled far ahead of the pack in Tuesday’s crowded primary, which attracted 11 candidates to fill an open seat. Tedford received 32.1% of the votes, and Lahmeyer drew 25.9%, according to the Oklahoma State Election Board.
Lahmeyer had been seen as a favorite, but his star fell in the days before the election amid revelations that he had been unfaithful to his wife. (He said the episode, which he confirmed, was a private matter and in the past, and Trump reaffirmed his endorsement following the revelation.)
Few if any of the nine candidates who did not make the runoff are part of the MAGA movement, suggesting that Tedford could see more of their supporters turn to him in November.
“We need everyone who came out today to keep fighting until we succeed,” Lahmeyer said in a statement to local media. “Let’s send a Trump-endorsed warrior to fight for Oklahoma values in Congress.”
The district is solidly red, virtually assuring the primary winner of victory in November. The Democratic candidate, John Croisant, is a Tulsa school board member who has not spoken publicly about Israel or Gaza, issues that are occupying some Democrats.

Democratic socialist whose Israel criticism ignited Jewish leaders’ concern leads D.C. mayoral primary vote
(JTA) — A democratic socialist who has sharply criticized Israel and pledged to defend Jews from antisemitism is in the lead in Tuesday’s Democratic primary for mayor in Washington, D.C., poising the nation’s capital to elect a progressive leader.
Janeese Lewis George, a D.C. Council member, had received just over half of the 65% of votes that had been counted by Wednesday morning. Kenyan McDuffie, a moderate and former City Council member, was in a distant second place.
The election is D.C.’s first using ranked-choice voting, so it could take some time to reach a final tabulation and the results could change. Still, the early results have ignited optimism among Lewis George’s supporters — and concern among her critics, who include Jewish leaders in the city and beyond.
Some Jewish leaders have criticized Lewis George, who has accused Israel of committing genocide in Gaza, for vowing if elected not to attend “events focused on obfuscating the realities of occupation or promoting Zionism and apartheid” or join “political junkets to Israel.” She made those promises in responses to a questionnaire from the Metro D.C. Democratic Socialists of America, which subsequently endorsed her.
The race set up a fight over the future of Washington, D.C., where the vast majority of voters are Democrats and the threat of President Donald Trump’s interference in city affairs loomed large over the ballot box. The winner is heavily favored to win the general election in November and succeed Democratic Mayor Muriel E. Bowser, who is retiring after 12 years in office.
It also has fueled a national discourse about the growing viability of far-left, anti-Israel politicians in local politics. Some have likened Lewis George to Zohran Mamdani, the democratic socialist elected mayor in New York City last year. A left-wing candidate is also poised to potentially become mayor of Los Angeles, while Chicago has had a progressive Democrat who is sharply critical of Israel since 2023.
The Wall Street Journal said ahead of the D.C. primary that the city was facing “a Mamdani moment” — a sharp critique from the paper’s conservative editorial board.
The leader of Our Revolution, a progressive group founded by Sen. Bernie Sanders, also embraced the comparison, telling USA Today that the success of left-wing candidates including Lewis George and Mamdani showed that voters want change.
Lewis George’s platform focuses largely on making D.C. more affordable. But controversy dogged her after her DSA questionnaire was published.
Ron Halber, head of the Jewish Community Relations Council of Greater Washington, told The Washington Post that the questionnaire raised “a lot of concern about whether an administration of hers would be sensitive to the Jewish community or not.”
Lewis George said in the DSA questionnaire that she would continue to meet with people and organizations that do not share all her values and opinions. She referenced a meeting she attended that was hosted by the JCRC, saying she disagreed with the group’s “opposition to using the word ‘genocide’ to describe Israel’s actions in Gaza” as well as “their definition of anti-semitism that criminalizes dissent, and their attacks on activists” but could also see areas of shared interest.
“I went to the event to advocate for an end to ICE collaboration, seek allies in that effort, and build on our shared goal of ending the inhumane treatment of our neighbors who are being taken by ICE,” she said.
Lewis George was endorsed by the Jews United for Justice Campaign Fund, which says it promotes economic, social and racial justice. The group said in its endorsement announcement that Lewis George would “fight for our communities and our Jewish values.”
After blowback to the DSA questionnaire, Lewis George privately met with local rabbis and Jewish community leaders in March to hear their concerns, according to Jewish Insider. Shortly after, she said in a statement on her campaign website that her “support for Palestinian human rights” and her “commitment against antisemitism” were not in conflict.
She added, “To the Jewish community in DC: I will not be a mayor who includes or excludes you based on your opinions or feelings on matters here and across the world. I will always protect your freedom, safety, and sense of belonging.”
Lewis George also said she had visited synagogues since she was in middle school and frequently worked with Jewish organizations as a council member, including to obtain security grants for synagogues and schools.
She went on to list her credentials as a supporter of Palestinians, saying that she was among the first Council members to call for a ceasefire in Gaza and meet with George Washington University students advocating for a ceasefire.
The DSA strongly opposes the Israeli government and requires candidates to share their views on Israel to secure an endorsement. While the party remains controversial in the Democratic establishment, Democrats nationwide have shifted their sympathies away from Israel since 2023, with 65% saying their sympathies lie more with the Palestinians in a February Gallup poll.
McDuffie criticized Lewis George’s answers to the DSA questionnaire and said there was “no place in this city for shutting out any community,” according to Washington Jewish Week. But he has largely avoided weighing in on questions about Israel, telling Jewish Insider that it was not the mayor’s role to craft foreign policy.
The Middle East receded to the background in the closing days of the mayoral race, which focused heavily on high costs of living in the district and fighting the Trump administration. Lewis George and McDuffie both argued they were better equipped to block interference from the federal government, as National Guard troops continue to patrol the streets amid Trump’s crackdown on immigration and tens of thousands of residents have lost their government jobs.
Meanwhile, Trump threatened at the Oval Office on Thursday to “take back” Washington and “run it on the federal basis” if Lewis George won.
The Tuesday primary used ranked-choice voting, which allows voters to rank up to five candidates. If no candidate reaches 50%, the last-place finisher is removed and voters for that candidate have their votes distributed among their second choice candidates. The process continues until one candidate has a majority. This voting method means that a final tally of results can take days after polls close.
