Want to use your gifts to help the climate? Here’s where seven climate advocates are donating.

Fighting for clean air and water. Accelerating the green energy transition. Centering economic and racial justice. Engaging future generations of climate innovators.
Nonprofits across the U.S. and around the world are tackling the problem of climate change in zillions of different ways. In recognition of the scope of their work, we at Heatmap are starting a new tradition for Giving Tuesday — asking some of the most prominent voices in the climate space where they would donate this year.
The answers they gave us are varied, exciting, and urgent, with a cause for every interest and concern. Learn how to donate or get involved with an effort close to your own heart, below.
What UPROSE does: Organizes the multiracial, multi-ethnic, multi-cultural population of Sunset Park, Brooklyn to promote sustainability and climate justice.
How you can support UPROSE: Get involved or donate here.
Where Yeampierre would donate this year: NYC Environmental Justice Alliance; NY Renews Climate; and Climate Justice Alliance.
Why: “All three of these organizations have a long and continued track record of shaping policy, base building, and operationalizing a just transition. All are frontline-led and center racial justice and equity in all aspects of their operations. All have changed the landscape and are central to decision-making on all things climate.”
What Generation180 does: Mounts public campaigns for electrification with relentless positivity.
How you can support Generation180: Donate here.
Where Wertz would donate this year: Hollywood Climate Summit.
Why: “This holiday season, I’d consider giving to Hollywood Climate Summit for their important climate communications work. Hollywood is an extremely powerful industry, and for the past four years, the annual Hollywood Climate Summit has served as an urgent call to action for the entertainment industry to address the climate emergency through a compilation of think tanks, workshops, and activities. The climate movement needs to change hearts and minds, and HCS is encouraging the entertainment community to help us achieve the cultural shift we need to advance an equitable, sustainable future.”
What the Indigenous Environmental Network does: Draws on the history of indigenous peoples to empower Native groups working to protect their homelands.
How you can support the IEN: Donate here or explore other ways to support the IEN.
Where White would donate this year: Tonatierra
Why: “We would love to spotlight the incredible work of Tonatierra. They are a family-based organization lifting up the grassroots from the local work on the ground to the United Nations. Sadly, they recently lost their co-founder, Tupac [Enrique Acosta].
“The work of Tonatierra in lifting up Indigenous communities over the past decades has been tireless and selfless. They fight for Indigenous Peoples community empowerment bringing together Indigenous people from the north and south in the fight for justice and human rights all within the framework of the protection of Mother Earth as we are all connected to the land.”
What the Rainforest Alliance does: Leverages business incentives to protect irreplaceable ecosystems — and the communities that rely on them.
How you can support the Rainforest Alliance: Get involved or donate here.
Where Katz would donate this year: Fundación Proyecto Tití and The Billion Oyster Project
Why: “Fundación Proyecto Tití works to stop deforestation and protect the cotton-top tamarin monkey. Also known as the tití, these one-pound primates are only found in the forests of Colombia, but deforestation is destroying their already diminished habitat. Only about 7,000 titís remain in the wild. The organization is effective in part because it works so well with the local community to protect endangered forests and replant degraded lands. The group has a U.S. sponsor, so all gifts are tax-deductible.
“The Billion Oyster Project is a growing New York-based conservation organization working alongside the Harbor School on Governor’s Island to clean up the New York estuary, once home to the largest number of oysters in the world. The Billion Oyster project not only grows oysters, [it] also helps everyone better understand the connection between clean water, biodiversity, and the food we eat. If Billon Oyster is successful — and they are well on the way — in the near future, all New Yorkers will have cleaner rivers and more wildlife thriving throughout the area.”
What SELC does: Defends the local environment in court, using the law to help move the U.S. South toward a more sustainable future.
How you can support SELC: Get involved or donate here.
Where Campaigne would donate this year: Memphis Community Against Pollution
Why: “Memphis Community Against Pollution has done some of the most impressive organizing around in its quest for environmental justice for Black communities in Southwest Memphis. The organization played David as it slayed the Goliath Byhalia crude oil pipeline, then worked successfully to force the closure of another facility that had been releasing toxic, cancer-causing pollution for more than four decades. MCAP has now focused its fierce attention on a climate behemoth: the quasi-federal utility TVA, which is proposing one of the largest methane gas buildouts in the country, a move that would lock the region into fossil fuels for decades to come.”
What Rewiring America does: Teaches U.S. homeowners about the tangible benefits of clean electricity.
How you can support Rewiring America: Get involved or donate here.
Where Young would donate this year: Community-based organizations like Baltimore’s Civic Works
Why: “Changing a handful of machines in our homes and driveways is one of the most important things you can do for the planet. The Inflation Reduction Act and climate philanthropists are accelerating this work at the national level, but for Giving Tuesday, we say go local. Community-based organizations with longstanding, personal connections and deep knowledge of the local landscape are often some of the best-positioned to advance electrification thoughtfully and equitably. This giving season, find an organization working to increase resiliency and improve the quality of life for their community by weatherizing low-income homes, providing financial assistance to install heat pumps, or advocating for local government action to help strengthen building codes and gain access to solar or EV charging.”
What the CATF does: Advocates for climate technologies to decarbonize the global energy system.
How you can support the CATF: Donate here or explore other ways to support CATF.
Who Shaheen would donate to this year: Western Resource Advocates, the Center for Applied Law and Policy, and ClearPath
Why: “We appreciate the work the following organizations are doing to advance effective, pragmatic solutions to climate change. In the U.S., we'd like to showcase Western Resource Advocates, which drives evidence-based solutions to the climate crisis, protecting and sustaining the environment, economy, and people of the interior West; the Center for Applied Law and Policy, which seeks to further innovation in environmental law and policy; and ClearPath, which develops and advances policies that accelerate innovations to reduce and remove global energy emissions.”
What RMI does: Brings cutting-edge research and analysis to business, governments, and the public to build a carbon-free future.
How you can support RMI: Explore ways to give here.
Where Singh would donate this year: Relp
Why: “Relp’s work not only addresses the pressing energy challenges in developing nations but also holds the potential to revolutionize the renewable energy landscape, forging a path toward a greener and more sustainable future for all. Their mission creates a ripple effect in the renewable energy sector, offering a way to scale renewable investments in regions that need them the most. Their comprehensive grasp of renewable energy markets combined with their ability to generate investment opportunities [that were] previously thought infeasible transforms what was once seen as unattainable into achievable milestones.”

On transmission corridors, China’s Russian reactor, and long-duration energy storage
Current conditions: Tropical Storm Cristobal formed in the Atlantic yet poses no real threats to land, unlike another budding storm gathering strength in the southern Caribbean • Powerful storms spurred derecho winds that spawned tornadoes across the Midwest and left 800,000 without power yesterday morning • Britain’s Met Office issued an amber weather warning as temperatures across eastern England soared to nearly 100 degrees Fahrenheit.

In the waning days of the Biden administration, the Department of Energy set about clearing one of the biggest bottlenecks to expanding America’s aging electrical grid: Literally expanding the grid. You don’t need to have read excellent books like Russell Gold’s Superpower or features like my colleague Robinson Meyer’s deep dive into the SunZia saga to know that building transmission lines is a huge challenge in the United States. To address this, the Biden-era agency proposed three National Interest Electric Transmission Corridors — essentially a series of projects in mostly red and purple states that could now enlist the federal government’s help to speed through the typical hurdles in getting approvals from so many jurisdictions and landowners across hundreds of miles of a power line’s route. Not anymore. On Wednesday evening, the Trump administration announced the cancellation of all three corridors, declaring projects that would likely have helped shore up the grid amid surging demand from data centers to be part of Democrats’ “Green New Scam.”
“Transmission policy must serve the American people — not special interests or a climate-alarmist agenda that drives up costs, worsens reliability, and disregards the concerns of local communities,” Secretary of Energy Chris Wright said in a statement. Still, his agency pointed to billions in loans it’s offered to utilities for grid upgrades and a study, released last month, highlighting what the Trump administration sees as the country’s future transmission needs. The rescission doesn’t necessarily mean the projects linked to the corridors are dead. When the Energy Department first announced the corridors in December 2024, the agency stressed that the designation didn’t guarantee federal approvals, merely speed projects on the pathway to getting answers. Those include NextEra Energy’s 73-mile Lake Erie Connector between Canada and Pennsylvania, two projects in the Southwestern Grid Connector Corridor, and the Transmission and Renewables Interstate Bulk Electric Supply Project in the Tribal Energy Access Corridor.
When Elon Musk announced plans last year to build out 100 gigawatts of solar manufacturing capacity, analysts and industry watchers scratched their heads. That’s more than double the amount of panels the U.S. installs each year at a time when photovoltaic factories face fierce competition from overseas competitors — namely China — and withering support domestically with the end of the federal tax credit designed to spur demand for American-made solar. Yet Musk is charging ahead with what Tesla has dubbed Project Crystal Sun. In a document submitted to Texas regulators, the company said it was “currently evaluating the feasibility of constructing its solar cell manufacturing facility at various locations across multiple U.S. states.” That includes the Lone Star State, to which Musk decamped from California. “Should Tesla make the decision to develop the proposed project in another state, Texas would miss the opportunity to attract billions of dollars in investment, help create thousands of full-time jobs for its residents, and become a hub for domestic solar cell manufacturing in the U.S.,” Tesla stated in the filing.
Things were also looking rosy for wind turbine manufacturers. Shares in Vestas closed nearly 20% higher on Wednesday after turbine orders bounced back, giving the company the liquidity to buy back its own stock. New orders for its turbines climbed from 2 gigawatts during the second quarter of 2025 to 3.35 gigawatts during the same period this year, the Financial Times reported.
The storms that barreled across the Midwest this week not only downed power for more than 800,000 people, they also left drivers without access to fuel. On Wednesday, the Northwest Indiana Times reported that gas stations in the region were running dry. “Today, we heard that this was open, and this is like the only thing that is open,” Mike Siedentopf, a resident of the Northwest Indiana town of Munster, told CBS News.

The flagship reactors in China’s nuclear buildout are the Hualong One and the CAP1400, each of which borrows heavily from America’s Westinghouse AP1000. But it’s useful to remember that Beijing is diversifying its atomic fleet. One of the next reactors likely to enter into commercial operations is now Unit 7 at the Tianwan nuclear power station on China’s Yellow Sea coast. On Wednesday, NucNet and World Nuclear News reported that the plant had loaded its first fuel assembly into position in the core of the new reactor. This marks the first time fuel has been loaded into a next-generation Russian reactor in China. Like the AP1000 and China’s versions of it, Rosatom’s VVER-1200 is a third-generation pressurized water reactor, meaning it uses the standard technology for fission with state-of-the-art safety and cooling upgrades. CNNC, the plant’s operator, said it expects to begin commercial operation later this year.
With the battery market booming, the race to commercialize long-duration storage technologies has yielded plenty of attention-grabbing ideas. Form Energy’s approach is proving particularly magnetic for investors. The West Virginia-based startup is seeking to bring rust-powered batteries that last 100 hours to market. On Wednesday, the company unveiled a $750 million Series G financing round, bringing the total equity it’s raised so far to over $2 billion. Its iron-air batteries, which charge through a “reversible rusting” process, have already attracted deals with Google, utility Xcel Energy, and data center giant Crusoe.
Meanwhile, a company commercializing compressed air storage technology just raised another $230 million. Hydrostor uses electricity to compress air and store it in underground hard-rock caverns using water displacement. When the grid needs power, the stored air is reheated and expands, spinning a turbine that generates emissions-free electricity. The Canadian startup pulled in more funding from the Canadian government’s investment fund, Goldman Sachs, and Canada’s pension funds. Another backer in this round is the oilfield services giant Baker Hughes. “The grid needs bankable long-duration energy storage that can be deployed today to enable affordable and reliable electricity for all, and Hydrostor’s continued fundraising success is a testament to the potential of our A-CAES technology to get us there,” Hydrostor CEO Curtis VanWalleghem said in a statement.
A Dr. Phil-linked expedition to find oil in Greenland has been delayed as the island nation’s government rejects the consortium’s right to drill. On Wednesday, the United Kingdom’s 80 Mile exploration company announced the delay in its plans. “While we are disappointed that the timing of the Jameson drilling program has been impacted, the company remains fully committed to advancing this highly prospective project,” 80 Mile executive director Rod McIllree told the Financial Times.

El Niño is here.
The world’s largest ocean slipped into the weather pattern in the spring, according to the National Oceanic and Atmospheric Administration, and the sea surface is now significantly warmer than average in one important region. When you chart ocean temperatures on a map, the “El Niño tongue” (yes, that is what scientists call it) clearly appears:

It might be more accurate to describe El Niño as something that happens to the planet, though. The Pacific occupies about one-third of Earth’s surface. When that third becomes unusually warm, it transforms weather around the world, driving wetter conditions in California, Central America, and South America; and drier weather in Asia, Africa, and Australia.
So far, so normal. El Niño is a standard fluctuation in the Earth’s climate system; we experienced the last one in 2023 and 2024.
But that is roughly where what’s normal about this year’s El Niño ends.
For one, this El Niño is far more intense than we should expect at this time of year. In an El Niño, the Pacific’s average temperature usually rises through the end of December or so; the phenomenon’s original name in Spanish, El niño de Navidad, alluded to the surprising arrival of warm currents in South America around Christmas. In the modern satellite era, the warmest El Niño ever measured happened in 2015, and ocean temperatures peaked at 3.1 degrees Celsius in November and December of that year. We called that a “Super El Niño” for just how abnormal it was.
Yet the Pacific is already more than 2.6 degrees Celsius (or nearly 5 degrees Fahrenheit) above normal — making this the third strongest El Niño ever measured in the satellite era — and it is only August. We still have four months to go, and this El Niño is already a record-smasher. More ominously, models expect that this El Niño could eventually grow to more than 4 degrees Celsius, or 7 degrees Fahrenheit, above normal.
What will that mean for the world? According to a recent Science study, the average El Niño can cost the global economy more than $3 trillion. The world is richer now than it was a decade or two ago, which should make it better able to withstand disaster. But this El Niño is so far out of sample that it’s hard to know what it could do.
And perhaps more importantly — as the climate scientist Zeke Hausfather, the guest of our new episode of Shift Key says today — it will offer a kind of preview of what the planet’s normal climate will resemble a decade from now. This El Niño is likely to push 2027’s average temperature above 1.5 degrees Celsius, the nominal threshold at which countries hoped to limit warming as part of the Paris Agreement (although, as you’ll hear, it is slightly more complicated than that).
Which is all to say: I encourage you to listen to our new episode, which is available on Apple, Spotify, or RSS. (A transcript is also available for Heatmap subscribers.) We tackle questions including:
There’s one thought that I didn’t include in the episode, however. Since late 2023, political discussion of climate change has decreased. This isn’t a phenomenon limited to any one faction of the Democratic Party — the progressives Abdul El-Sayed and Zohran Mamdani have downplayed climate policy roughly as much as, say, moderates like Mary Peltola and James Talarico have — but it is a clear trend. The American media’s coverage of climate change has declined during the same period. This “climate hushing” is not because politicians stopped caring per se, I think, but because nobody is sure how to talk about the issue in a politically useful way anymore, especially after the “climate = jobs” rhetoric that underpinned the Biden administration’s policy failed to retain voters in 2024.
I don’t believe (and think that political science has disproven) that extreme weather can “awaken” the public to climate change. Even against a gradually warming baseline, the weather — and public attention — shift far too often for that. But media coverage is loosely responsive to events. When the super El Niño of 2015 and 2016 smashed the then-record for the hottest year ever measured, it helped initiate a new era of public and elite concern about climate change. That El Niño’s heat waves, wildfires, and mass coral bleaching previewed the far worse disasters of the decade that followed. This El Niño’s disasters and broken temperature records could be worse — and even less ignorable.
On copper prices, nuclear’s jellyfish woes, and Leo DiCaprio’s Chilean NIMBYism
Current conditions: The death toll from Colombia’s earthquake has risen beyond 250 • A severe thunderstorm flipped a car in Columbus, Ohio, as a large system swept across the Midwest • A partial solar eclipse is set to occur the Northeast.

David Crowley, a moderate Democrat and local official in Milwaukee, narrowly defeated Francesca Hong, a leftist state lawmaker and former ramen chef, in the Democratic gubernatorial primary in Wisconsin last night. The race marked one of the most significant tests of Democratic voters’ willingness to elect a member of the ascendant Democratic Socialists of America, now the most popular socialist group in U.S. history. Her campaign promised to make childcare and school lunches free, repeal anti-union laws, and give renters more protections against eviction. She also pitched what she called her “control-alt-delete” plan to eliminate tax credits for data centers and put a statewide moratorium on permits for new artificial intelligence facilities.
Ahead of Tuesday’s primary, the AI developers Vantage, Oracle, and OpenAI announced a $60,000 community investment in Port Washington, which my colleague Jael Holzman described as “the most controversial data center development area in the state.”
Just last week, the Trump administration agreed to pay the energy giant RWE more than $1.2 billion to abandon an offshore wind project, the latest in a series of deals in which taxpayers hand over billions to not receive new sources of clean electricity they badly need. On Tuesday, Senators Alex Padilla, the California Democrat, and Angus King, the independent from Maine, introduced a bill that would give companies that reject Trump’s payouts an expedited route to more development. “The Trump Administration is doing everything it can to kill California’s offshore wind future, handing energy companies billions of taxpayer dollars to walk away from projects that would have powered millions of homes,” Padilla said in a press release. “This bill makes sure their destructive approach doesn’t waste what’s already been invested so we can get these leases back to work, create the jobs Trump killed, and keep energy bills low for working families instead of letting his war on renewables cost Californians even more.”
The bill has one potential flaw, other than the fact that Republicans are unlikely to pass it and President Donald Trump is even less likely to sign it. That, as my colleague Robinson Meyer wrote this week, is that the roughly $4 billion in payouts so far went to projects that were “already dead or dying.” The money spent, in other words, is “for nothing.”
Please read the following two sentences in the tone of the famous scene of Tony Soprano defending Christopher Columbus: In this newsletter, Ea-nāṣir, the Mesopotamian copper merchant from Bronze Age-era Ur whose stone-carved complaints about a subpar metal shipment remain readable millennia later, is a hero. End of story! Why, you might ask? Because we are once again living through an age where copper, the basic building block of all things electric, is in high demand. Copper soared back to within half a cent of its record high Tuesday of nearly $14,000 per metric ton after an outage at a major smelter in Indonesia rattled global prices, Mining.com reported.
The fight over North America’s only major cobalt refinery, meanwhile, is heating up. The mining giant Glencore made a bid for control of Sherritt International, which has taken a beating from U.S. sanctions due to its 50% stake in Moa, a joint venture with the Cuban government. The joint venture’s assets include the Canadian refinery and Moa nickel-cobalt mine in Cuba. The Glencore-backed consortium is up against Gillon Capital, the family office of Ray Washburne, a Republican fundraiser and former Trump official, according to the Financial Times.

Weeks after Europe’s latest heat wave forced inland nuclear stations to pare down output for lack of cooling water in the continent’s rivers, a “massive influx” of jellyfish has forced France’s EDF to shut down three units at its Gravelines nuclear station and cut power from a fourth. That’s taken at least 3.2 gigawatts of capacity offline, Bloomberg reported, right as temperatures are expected to surpass 104 degrees Fahrenheit in the coming days. The unusually hot temperatures off France’s shores have encouraged jellyfish populations to “bloom,” clogging the pumping stations through which coastal nuclear plants like Gravelines pull in cooling water.
In Egypt, meanwhile, construction crews working on the country’s first nuclear station hit a critical milestone. The containment vessel for the Russian-designed El Dabaa plant’s first unit is nearly completed, according to World Nuclear News.
Digging deep enough into the bedrock around New York City to tap into lava-hot rocks for electricity production is probably still years away, despite the progress that next-generation geothermal companies such as Fervo Energy have recently made. But thermal networks that maintain a steady environment year-round by circulating air at a constant temperature are increasingly popular ways for New Yorkers in private homes outside the city to stay warm in winter and cool in summer. Now the city itself is seeing whether a large-scale version could work for the subway system and municipal buildings. A study is set to begin soon into whether a thermal energy network could be built along subway routes to capture, store, and redirect excess heat that accumulates in the Brooklyn Bridge-City Hall and Chambers Street station complex to municipal buildings above ground. “Radiant cooling technology will absorb heat from the subway platforms and transfer it to geothermal boreholes drilled beneath Chambers Street,” reporter Carlo Cariaga wrote for Think Geo Energy. “This excess heat will then be stored underground until it can be used for supply to nearby municipal buildings during winter.” The contract for the feasibility study is due to be awarded in the fall, with work scheduled to start in early 2027.
“It seems like it’s a good place to test geothermal solutions because it sounds like there is a part of the tracks that isn’t being used, so they don’t have to stop service,” Jack Klein, the citizen researcher who conducted his own gonzo Subway heat study last year, told my colleague Jeva Lange this week.
Leonardo DiCaprio has long been a major donor to environmental causes. But rarely has the actor taken as clear a stance against green development if it comes at any ecological cost as this. On Tuesday, Bloomberg reported that the Oscar winner had told his nearly 60 million Instagram followers that fewer than 1,000 Pehuenche spiny-chest frogs remain in the wild, and that construction of the proposed Chile-Argentina transmission line threatens the amphibians’ habitat. “Conservationists are not asking for the transmission project to be stopped,” the celebrity wrote in the post over the weekend. “They are asking for it to be built where it does not put a Critically Endangered species at even greater risk.”
