Hot and bothered: Young Jews are demanding action on climate change

This article was produced as part of JTA’s Teen Journalism Fellowship, a program that works with Jewish teens around the world to report on issues that affect their lives.
(JTA) — On an unusually warm February day, approximately 200 Jews gathered at the Hebrew Educational Alliance in Denver, Colorado for the inaugural Colorado Jewish Climate Summit, which coincided with Tu Bishvat, the new year of the trees.
Among the attendees were about 20 teens, who filed into the sanctuary, past tables stacked with brochures on sustainability and vibrant tapestries portraying Torah stories. They clustered into wooden pews, discussing the climate workshops they would attend — or lead.
“In the Jewish community, we talk about being collective in our efforts. And climate change is the same way — it’s not what one of us does, it’s what many of us do,” said Noah Shurz, a 16-year-old from Denver who helped plan the summit.
As the climate crisis and the global response to it intensifies, many Jewish teens are utilizing the intersections of Jewish and environmentalist teachings as impetus for activism. Through participating in groups like Jewish Youth Climate Movement, Dayenu and Jewish Climate Action Network, teens are strengthening their connection to Judaism and deepening their sense of community. Values like Tzedek Tzedek Tirdof (“justice, justice you shall pursue”), Tikkun Olam (“repairing the world”) and L’Dor V’Dor (“from generation to generation”) fuel their activism. These activists bring a unique perspective to the movement, combining the fervor of young changemakers with the tradition of the Jewish people.

“My Judaism and my desire to fight against climate change go hand in hand,” said Rivka Schafer, a Modern Orthodox 18-year-old from Teaneck, New Jersey who uses they/them pronouns. In their role as co-director for Jewish Youth Climate Movement, a youth organization founded in 2019 that has about 450 members, Schafer acts as the bridge between youth leaders and adult staff.
Schafer described participating in climate action as almost a religious obligation. “When I go into nature, I feel inherently connected to God,” said Schafer. “To see that loss of our natural world to me resembles a loss of spirituality as well.”
Schafer became a climate activist at age 12 after seeing bleached coral reefs firsthand during an underwater dive. “For the first time, it hit me, the destruction we are causing our world,” they said. “I decided that if the government wasn’t doing anything to fix the world, and if the adults weren’t doing enough, then it was up to me to bear that responsibility of healing our planet.”
Schafer’s co-director, Amber Marcus-Blank, 18, from Sharon, Massachusetts, shares this connection to the natural world. “There is a very similar feeling that I get when I’m reading Jewish prayers and when I’m in nature,” said Marcus-Blank.
In the past, Jewish Youth Climate Movement has pushed for banks to divest from fossil fuels, participated in and led climate protests and sent youth representatives to the U.N COP27 climate conference. More recently, as smoke from wildfires engulfed the eastern U.S, causing alarmingly poor air quality, JYCM teens connected the Biblical concept of neshama (both “breath” and “soul”) to the climate fight. The organization challenged their Instagram followers to “fight to protect the sanctity of our breath and the right for all communities to breathe safe and clean air,” suggesting actions like calling representatives to pass climate legislation like the NY HEAT Act.
The organization works with local Jewish institutions to create change within Jewish communities. Institutions “can look at implementing recycling/compost…can encourage transit usage by trying to get a bus stop next to them, or having bike parking and reducing car space: things to get people to see what they could also do in their household… and advocating for [climate action] bills,” said Shurz. JYCM teens lead sustainability trainings at Jewish institutions, build resources, run the social media accounts, and organize demonstrations; a few adult staff handle behind the scenes work.
Jewish activists use similar tactics to other groups — such as divestment campaigns or changes to unsustainable infrastructure — but their actions are by, about, and for Jews. Groups like JYCM make helping synagogues or day schools become more sustainable, a top priority.
For example, many synagogues, with assistance from Adamah (previously Hazon), are moving towards greener energy. The organization provides energy audits, educational resources, and institutional partnerships via their Jewish Climate Leadership Coalition (with more than 30 institutions across the country). Youth activists help educate Jewish communities as to the necessity of the program.

Some teens interviewed say they were previously engaged in non-denominational climate action, but that Jewish activism serves their needs better. “As an Orthodox Jew, I keep Shabbos, I keep kosher,” said Schafer. “I wanted to be in a place where people would understand me and be respectful of my religious observances, so it just didn’t make sense for me to join [a climate] organization that wasn’t Jewish.”
Their co-director, Marcus-Blank, said that the intersectional nature of JYCM — Jewish, youth, climate — provides space for all her interests. “It allows me to be my full self in a way that I can’t really be in any other space.” She felt limited by other organizations: struggling with not discussing Judaism in secular climate spaces or climate in Jewish spaces, and sometimes, given her age, being ignored in both spaces.
“Being Jewish is what led me to [climate activism],” said Marcus-Blank. Being taught tikkun olam, surrounded by Jews who took action for the things they believed in, contributed to her desire to pursue environmental activism.
Not only can Jewish values like Tikkun Olam be connected to environmentalist principles, but many of those principles are explicitly found in Jewish teachings. Judaism regards human beings as the “guardians of the earth.” It dictates that God created the universe and it is the duty of humans to protect it (stewardship). Nature is woven into much of Judaism — from environmentally related holidays such as Sukkot or Tu Bishvat, to the Tree of Life, a metaphor for the Torah. Jewish tradition also supports modern sustainability concepts such as regenerative agriculture and low waste living.
Nevertheless, the Jewish presence in the climate movement is relatively recent. The first official Jewish-environmentalist organization, named Shomrei Adamah (for the Hebrew phrase “keepers of the earth”) was created in 1988 by Rabbi Ellen Bernstein. The organization’s mission was to “illuminate and make accessible the ecological roots of Jewish tradition and to inspire Jewish individuals and institutions to care for the earth and act on her behalf.” It has since been joined by other groups, such as Adamah (the parent organization of JYCM), which formed with the merger of Hazon and Pearlstone.
Recently, the field of faith-based activism has become more diverse, with interfaith organizations such as Greenfaith gaining prominence. Jewish climate activism also has been increasing as more Jews learn of the scale and speed of the threat.
Through JYCM, teens also learn more about Judaism. Marcus-Blank learned about nigun, a form of sung prayer, at a retreat with JYCM in 2022. During Dayenu’s 2022 “All Our Might”campaign, JYCM youth activist Lexie Miller brought matzah to the leader of a Wells Fargo bank as symbolism for the limited time remaining to fight the climate crisis – just as the Jews had limited time for the matzah to rise.
JYCM also conducts trainings relating Jewish persecution and perseverance to climate action. Miller, who serves on the JYCM national youth leadership board, helps to create ‘equity and inclusion’ resources explaining to youth that now is a time that Jews must fight for survival, just as in the past. “I perceive the threat of climate change very similar to how I felt people in the Torah must have felt when their homes were threatened,” said the 13-year-old from Boulder, Colorado. The concept of justice for Jews and other marginalized groups plays a large role in JYCM’s philosophy. “All of our Jewish teachings tell us to stand up for those who can’t stand up for themselves and to care for the world. That’s why climate activism and [equity and inclusion] is rooted so much in Jewish history,” said Miller.

For the Colorado Jewish Climate summit, the teens planned with adult organizers for months. The event was similar to others that Jewish teens are coordinating across the country. The summit came to fruition under the direction of Colorado Jewish Climate Action, and included Rabbi Jenni Rosen of Dayenu and a message from U.S senator Michael Bennet. Colorado Jewish Climate Action hopes to collaborate further with the youth activists; in the future, the Denver kvutzah will serve as a youth outreach partner.
Many teens choose Jewish-based climate action because it fosters community. “[The other teens] inherently understand some of the biggest components of my identity and the things I value,” said Schafer.
Taking action in these groups can also alleviate burnout, a common phenomenon experienced in climate activism. “In this line of work, where you’re facing an existential crisis, it’s not a tangible goal that you’re reaching for. And so it can be really easy to get burned out and be disappointed by the lack of action,” said Marcus-Blank. “JYCM is what kept me going, because these people have so much hope and optimism.”
These teens combine the ideals of youth and deep-seated values of Judaism as fuel for continued engagement in the climate movement; especially l’dor v’dor, “from generation to generation,” the value of preserving/protecting Jewish faith and livelihood in the face of adversity in order for future Jews to benefit,
“There’s a certain urgency that comes with young people, because we are starting to see the effects of climate change in real time. My Jewish values project that urgency because I’m really in tune to wanting to help people,” said Marcus-Blank. “And the persecution of Jews has always created changemakers. So both of those things go hand in hand.”

French Authorities Replant Memorial Olive Tree and Launch Seventh Ilan Halimi Award

French authorities planted a new olive tree on Wednesday to honor Ilan Halimi, nearly a decade after the young French Jewish man was tortured to death and two weeks after a previous commemorative tree was cut down.
Hervé Chevreau, mayor of the norther Paris suburb Épinay, announced that several olive trees will be replanted in Halimi’s memory, praising “a remarkable outpouring of solidarity” reflected in the donations.
With a commemorative ceremony on Wednesday, the first olive tree will be planted in Saint-Ouen, a northern suburb of Paris in the Île-de-France region.
“In the context of rising antisemitic acts, the community aims to reaffirm its steadfast commitment against hatred, forgetfulness, and indifference,” Chevreau said in a statement. “This gesture of reflection and resilience responds to the serious act of vandalism in Épinay-sur-Seine, where the commemorative tree was deliberately cut down.”
Halimi was abducted, held captive, and tortured in January 2006 by a gang of about 20 people in a low-income housing estate in the Paris suburb of Bagneux.
Three weeks later, he was found in Essonne, south of Paris, naked, gagged, and handcuffed, with clear signs of torture and burns. The 23-year-old died on the way to the hospital.
In 2011, an olive tree was planted in Halimi’s memory. Earlier this month, the memorial was found felled — probably with a chainsaw — in Epinay-sur-Seine.
Halimi’s memory has faced attacks before, with two other trees planted in his honor vandalized in 2019 in Essonne.
During Wednesday’s ceremony, numerous prominent figures attended, including France’s Chief Rabbi Haim Korsia, Yonathan Arfi, President of the Representative Council of Jewish Institutions in France (CRIF), Labor Minister Astrid Panosyan-Bouvet, and Minister for Gender Equality and the Fight Against Discrimination Aurore Bergé.
At the event, Bergé announced the launch of the seventh edition of the Ilan Halimi Award, marking 20 years since his disappearance.
Established in 2018, the award seeks to fight racism and antisemitism by inspiring young people to take action.
Since then, French authorities have annually recognized projects led by young people aged 13 to 25 from schools, universities, associations, and civic or integration programs.
“The launch of the 2026 edition of the Ilan Halimi Award in Sainte-Geneviève-des-Bois is more than an act of remembrance — it is a pledge to the future,” Bergé said during the ceremony.

Last week, two 19-year-old Tunisian twin brothers, undocumented and with prior convictions for theft and violence, were arrested in France for allegedly vandalizing and cutting down Halimi’s memorial.
Both brothers appeared in criminal court and were remanded in custody pending their trial, scheduled for Oct. 22.
They will face trial on charges of “aggravated destruction of property” and “desecration of a monument dedicated to the memory of the dead on the basis of race, ethnicity, nationality, or religion,” offenses that, according to prosecutors, carry a sentence of up to two years in prison.

After Deadly Firebombing, Boulder Jews Forced to Hide Weekly Hostage March Due to Escalating Harassment

A group of Jewish activists advocating for the Israeli hostages still held captive by Hamas terrorists in Gaza has announced plans to cease publicizing planned demonstrations and increase security in response to continued community intimidation in the months following a June 1 Molotov cocktail attack that left one person dead and 13 injured.
The group Run for Their Lives includes more than 230 chapters globally, and the one based in Boulder will now take extra measures to protect participants since the attack, for which authorities have charged alleged assailant Mohamed Sabry Soliman, which has in turn provoked further opposition.
Videos reviewed by the Jewish Community Relations Council (JCRC) show anti-Israel demonstrators calling event attendees “Nazi,” “racist,” and “genocidal c**t.”
A local politician running for city council has also demonized the hostage supporters.
CBS Colorado reported that Aaron Stone allegedly called Rachel Amaru, the chapter’s Jewish founder, a “Nazi,” a slur he defended as “a very strong word to use.” He further said that in looking at Amaru he was “not seeing a Jewish person” but rather “someone who is walking down the street talking about 20 hostages and ignoring the two million Palestinian hostages that are being kept in Gaza.”
Brandon Rattiner, senior director of the local Jewish Community Relations Council, said in a statement that “participants are facing a level of harassment that makes it impossible to continue safely in public view.”
Stefanie Clarke, who serves as co-executive director of Stop Antisemitism Colorado, added in a statement that “it is unacceptable that less than three months after a deadly antisemitic attack, Jews in Boulder are once again being forced into hiding.”
Clarke stated that “we will not be intimidated, and we will not be driven out of public spaces where we should feel safe. The fact that someone seeking a seat on City Council is at the center of this harassment should be cause for alarm. Boulder cannot claim to be a city of inclusion and justice while giving a platform to Jew hate.”
The mountain states regional branch of the Anti-Defamation League (ADL) released its own statement in support of the pro-Israel activists.
“We stand in firm solidarity with the Boulder chapter of Run for Their Lives following their difficult decision to no longer publicly disclose the location of their events,” the organization said. “It is deeply unfortunate that after enduring the horrific June 1 firebomb attack that resulted in the death of a community member, participants now face such persistent harassment that they must keep their gatherings secret to simply stay safe.”
On July 15, Soliman, who pleaded not guilty, waved his right to a preliminary hearing in a case where the 150 state charges and 12 federal charges include murder and attempted murder. He will see a judge on Tuesday for a scheduled arraignment and faces life imprisonment if convicted.
Prosecutors say that Soliman, an Egyptian who came to the United States on a B-2 Tourist Visa in August 2022, told police that “he wanted to kill all Zionist people” and that he sought to murder 20 of the demonstrators. A note found in his car read “Zionism is our enemies untill [sic] Jerusalem is liberated and they are expelled from our land.”
Soliman also reportedly said that he had planned the attack for a year and planned it for after his daughter’s graduation. Federal officials sought to deport Soliman’s family; however, a judge blocked that effort.
“This is a proper end to an absurd legal effort on the plaintiff’s part. Just like her terrorist husband, she and her children are here illegally and are rightfully in ICE [US Immigration and Customs Enforcement] custody for removal as a result,” Tricia McLaughlin, assistant secretary of the Department of Homeland Security, said in a statement. “This terrorist will be prosecuted to the fullest extent of the law. We are investigating to what extent his family knew about this heinous attack, if they had knowledge of it, or if they provided support to it.”
In August, the ADL released a report ranking Colorado — which contains approximately 110,400 Jewish residents, accounting for 1.9 percent of the population — as eighth in the country for combating antisemitism.
“I am thrilled that the Anti-Defamation League has recognized Colorado as a national leader in fighting antisemitism, but there is much more to do,” the state’s governor Jared Polis said at the time. “Such hate and violence have no place in our Colorado for All, and that is why Colorado is leading the way to combat these trends and protect Coloradans’ right to worship how you want, making Colorado safer.”

Lead Writer of Upcoming DC Comics Series Celebrated Oct. 7 Massacre in Resurfaced Social Media Posts

Gretchen Felker-Martin, an author and film critic who was recently announced as lead writer of the upcoming DC Comics series “Red Hood,” has an extensive history of endorsing terrorist acts and defending the murder of Jews and Israelis, according to a review of the writer’s social media posts.
In the posts — screenshots of which circulated on X/Twitter and other platforms this week — Felker-Martin appeared to praise Osama bin Laden for the Sept. 11, 2001, terrorist attacks in the US and expressed support for Hamas’s Oct. 7, 2023, invasion of and massacre across southern Israel.
During the Oct. 7 onslaught, as Hamas-led Palestinian terrorists murdered 1,200 people and kidnapped 251 hostages in the deadliest single-day slaughter of Jews since the Holocaust, Felker-Martin argued that Israeli civilians are “settlers” and an “occupying force whose daily lives serve to grind out the hope, culture, and memory of those they oppress.” She also seemingly defended Hamas’s murdering of Israeli babies, saying that Israel is an “imperialist nightmare” and that Hamas is trying to “survive their rule by any means necessary.”
Hamas is designated by several countries as a terrorist organization.
“You cannot subject human beings to brutal conditions under which no hope for a meaningful future exists and then blame them for violent action taken to correct this state. Free Palestine,” she wrote on Oct. 7.
Later that month, Felker-Martin wrote that “Zionism is full-fledged Nazism and has accrued mainstream support throughout the west because of that, not in spite of it.”
.
As the ensuing war in Gaza continued in the months ahead, Felker-Martin sharpened her criticisms of Israel, condemning Zionists as “crazy” and comparing them to “slime.” The writer also lambasted Neil Druckmann, the Israeli creator of the popular “The Last of Us” video game series, for being a “Zionist.” She encouraged fellow progressives not to support then-US Democratic presidential nominee Kamala Harris, condemning Harris for not “moving an inch on the genocide.” She also falsely accused Israel of inflicting a “famine” in Gaza and repudiated actress Hailee Steinfeld as a “Zionist piece of s**t.” Steinfeld has seemingly not made public statements about Israel but came under fire from leftists after she visited the Jewish state with family in 2019 for a party.
Felker-Martin separately defended Osama bin Laden’s role in the Sept. 11 terror attacks, writing that “blowing up the World Trade Center is probably the most principled and defensible thing he ever did.”
Jewish organizations and antisemitism watchdog groups quickly condemned the remarks. StandWithUs, a nonpartisan pro-Israel organization, urged DC Comics to reconsider hiring Felker-Martin, citing her inflammatory and offensive commentary.
