Stumpy stands alone.
It’s hard to miss, rising scraggily up from the soil on the southeast side of the Tidal Basin in Washington, D.C. It picturesquely frames the Washington Monument with an outstretched limb, which also happens to be its only limb.
Stumpy is a Yoshino Cherry tree, a Prunus x yedoensis, one of the thousands that line the water of the Tidal Basin, and it’s been having a bit of a rough time lately. The nearby seawall, built 80-odd years ago, has slowly been settling into the mud and the muck, dropping about three feet in the time since it was built. High tide is also a foot higher now, and twice a day Stumpy’s roots are inundated with brackish water that’s saltier than the nearby Potomac River — a state of being that is no good for a tree. The trunk looks mostly hollow, like someone took a few large scoops out of it. All but one of the branches have rotted away and been trimmed by its caretakers at the National Park Service, leaving Stumpy with a windblown toupee of sticks, leaves, and buds.
Naturally, people are obsessed.
“This is my ninth cherry blossom season and I would be hard pressed to find another tree that’s gotten either a name or that sort of fame,” said Mike Litterst, Chief of Communications for the National Parks Service and Stumpy’s de facto spokesman. “People are literally lining up to take photos with it this year, and somebody’s even got Stumpy t-shirts now.”
Stumpy’s story began as a Reddit post in 2020, when a user said the tree was “as dead as my love life.” Stumpy is, of course, still kicking, and the Redditor met a girl, but for reasons unknown to everyone including the National Parks Service, the tree has been more popular this year than ever before. Perhaps D.C. was primed for Stumpy’s resurgence; back in December, residents of the Columbia Heights neighborhood became similarly obsessed with a diminutive Christmas tree they’d nicknamed Tiny Timber.
We like to tell stories about trees, and lately I’ve noticed them cropping up more often. Perhaps this is just frequency bias, the detritus of spending the early pandemic in a house with a maple tree in the backyard, where for the first time in my life I found myself paying attention to arboreal rhythms as the seasons changed. But we all, to some extent, became amateur naturalists in lockdown, and the trees (and the birds) are what remain.
Stumpy and Tiny Timber both belong to the Charlie Brown class of trees, the ones that, because of their smallness and sadness and apparent untree-ness, evoke a kind of empathy that allows us to give human emotions to them. Litterst thinks this is why Stumpy is so popular this year — it’s an underdog, and we like underdog stories.
Then there are the stories of magic and majesty, like The Giving Tree and the Kalaloch Tree of Life in Washington State and The Overstory, winner of the 2019 Pulitzer Prize in Fiction. These are the trees that make us feel small; we gape at their stoic enormity, the generosity with which they share their shade. I think these are the same reasons why tree planting is such a popular, if misguided, climate solution: We are so drawn to the idea of trees being older and wiser than us, we take such comfort in their leaves and branches, that we can’t help but hope they will fix our mistakes for us.
They won’t, of course, and perhaps we ought to reexamine our expectations of trees. Their effects on our planet are matters of circumstance rather than agency; trees, after all, may have accidentally killed off half the planet when they evolved roots a few hundred million years ago. They didn’t know what they were doing then, and they don’t now — an idea I find somewhat freeing, for it lets a tree simply be a tree.
Take Stumpy. Peak bloom was over by the time I made the pilgrimage to see Stumpy for myself: Its flowers and the crowds were both gone, although one couple briefly stopped on their walk to quickly chuckle at Stumpy before continuing.
There’s a sort of solemn quietude to Stumpy without the crowds. There were other, more conventionally beautiful cherry trees nearby, a few of them still hanging onto their pink and white flowers. But Stumpy, standing by the water on its own, with its one lone branch pointing towards the Washington Monument, bucked the trend, as if someone had dropped in a bonsai among the rest.
It reminded me a bit of another out-of-place plant I’d seen, back in 2019, when a tomato sprouted in a wooden piling in the East River, just off Brooklyn Bridge Park. That, too, was the kind of thing that made people stop and point and laugh, but with the kind of laugh one emits when they crawl to the edge of a cliff and look out at the sea yawning below. An errant seed or a stubborn tree: These are conduits for wonder, whispers of the ecosystems we inhabit.
They’re also reminders of our roles as stewards. Despite how it looks, the fact that Stumpy flowered means it’s in pretty good shape overall, Litterst told me, and the parts of the trunk that deliver nutrients to and from the remaining branch are still working as they should. Plans for a new, improved seawall — one that’s embedded in the bedrock unlike its predecessor, so it doesn’t sink — are in the works, with construction planned to begin next year. The National Parks Service doesn’t know how long Stumpy has left, but if it manages to hold out until the seawall is finished it’ll eventually be spared the rising tides and could live to see some of its brethren take their places alongside it.
I’m sure they’ll be pretty, in the way cherry blossoms always are. But I’ll still be going back for Stumpy.

Misan Lychee is made with “some” carbon dioxide captured “directly from the air,” along with 14.6 grams of added sugar.
I believe life should be a little bit silly, which is why I’m a sucker for a gimmick. A hotel just for napping? Sign me up. A “convenience store” full of items made of felt? I now own a bag of inedible Fritos. Hot sauce packaged to look like dynamite? Cute, add to cart.
And when I found out that you can buy soda carbonated with CO2 obtained via direct air capture, I said, Take my sixteen American dollars and put it on ice.
Misan Lychee (which yes, only comes in lychee flavor “at the moment”) represents the distant hopes and dreams of DAC. Currently, there isn’t demand for carbon dioxide at direct air capture prices; it’s much, much cheaper just to buy the concentrated byproduct of, say, natural gas- and coal-fired ammonia plants to carbonate your soda than to go through the trouble of sucking the 0.04% of the air that is CO2 out of the atmosphere for a few bubbles. That’s why the carbon removal industry is propped up by offtake agreements and credits, at least until Brutalism comes back in a big way and dramatically increases the demand for concrete manufactured with stored CO2.
Still, that hasn’t stopped companies from trying. You can buy carbon-sequestered beer, DAC vodka, CO2-captured perfume, and recycled-emission yoga pants. But unlike other consumer products that are, in many cases, made from waste gas captured during industrial processes rather than from true atmospheric CO2, Misan claims on the can to be made from “some” carbon dioxide pulled “directly from the air using a technology called direct air capture.” The bottle sports the logo of Bay Area-based AirMyne, a DAC start-up, which, on further investigation, turns out to own Misan.
My order arrived rattling around in a cardboard box, with three of the cans having popped loose from the six-pack in transit. As someone with no impulse control (which, upon reflection, might be related to my love of gimmicks), I immediately opened a can. Over my laptop. We both got drenched by the resulting geyser. CO2’s presence: confirmed.
What happened next was, admittedly, also user error. I took a sip and immediately went, “Yuck, what?” That’s because after a summer of drinking my way through every Waterloo flavor, I was expecting Misan Lychee to be a seltzer, too. Despite its website describing it as a “climate-forward sparkling water,” it is not, and you can taste all 14.6 grams of its added sugar. It has a moderately cloying, perfumy flavor that my dad described as “strawberry, but disturbing?” when I asked him to do a blind taste test. I think it’s perhaps closer in taste to pear, and I remain optimistic that someone who has more free time than me could come up with a recipe to turn it into a “sustainable” spritz.
Actually, to that point — is it sustainable? It notably doesn’t claim to be, and it has its skeptics. Richard Waite of the World Resources Institute pointed out on Bluesky that carbon dioxide is only “sequestered” until it leaves our metabolic system the usual way, via exhalation or burps. Still, his questions about the energy source of AirMyne’s direct air capture — and thus the carbon-emitting or -removing properties of the soda — generated lots of good puns in the replies. “Run out of polar before we run out of Polar” comes to us courtesy of Costa Samaras.
The second Misan Lychee I cracked also soaked me, although I was prepared this time and at least opened it out of range of electronics. I also paid more attention to the can, which has an unusual but not unpleasant matte feel. The list of ingredients on the back seems surprisingly long for the supposed golden age of “gut sodas” that advertise such things as the inclusion of “plant fibers.” Rather than prebiotics, Misan contains “xanthan gum” and an ominous concoction identified as “cloudy agent.”
If Misan isn’t healthier for me or the planet, then what is it for, exactly? I returned to the six lines of all-caps text printed on the front of the can:
Some of the CO2 in this can was pulled directly from the air using a technology called direct air capture (DAC). If scaled, DAC could do more than just carbonate your water. It could remove millions of tons of CO2 from the atmosphere, fighting climate change.
Gimmicks are, ultimately, ways to sell you something. Water gets packaged to look more “manly;” you might buy a Coca-Cola instead of a Pepsi if it has your name on it. But Misan isn’t ultimately selling itself with the promise of bubbles brought to you by DAC. It’s the other way around: Misan is the marketing vehicle for AirMyne. They want you to drink the DAC Kool-Aid.
Will I buy Misan Lychee again? Not likely: I have De La Calle! Mango Chili Mexican sodas to drink, made from the fermented rind of pineapples — BYOCO2, if you will.
Then again, never say never. If I learn about the existence of Misan Chikoo or Misan Pistachio-Rosewater during a weak moment, I’ll probably be down another $16. But I’ll open it over the sink this time.
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.
