♫ It’s getting hot in here, so close up all your domes ♫
Home runs ain’t the half of it.
Last week, the Bulletin of the American Meteorological Society issued a widely cited report that found global warming is “juicing” baseballs. The result is an extra 50 or so home runs per year in the major leagues. “It’s basic physics,” The Associated Press explained. “When air heats up, molecules move faster and away from each other, making the air less dense. Baseballs launched off a bat go farther through thinner air because there’s less resistance to slow the ball.”
Baseball fans have long been aware that hot weather makes for more home runs, so it follows that increasing temperatures will have an impact on the game in the years ahead. But MLB has more to worry about than the game becoming boring again because of too many dingers. Here are a few more ways climate change could irrevocably alter the future of America’s favorite past time:
We’ve already covered how the ball will behave differently off the bat. But what about out of the hand?
Heat and high humidity mean less air density, which in turn causes “fastballs to be faster, curveballs to curve less, and spin rates of pitches to be higher,” wrote Lawrence Rocks for SABR’s “Future of Baseball” issue in 2021. Of course, “these factors will cause pitchers to change their usage percentages on their pitch selection.”
As lowland parks grow hotter, we can expect them to behave more like the famously thin-aired Coors Field in Denver — particularly Atlanta, Kansas City, and Houston, which have among the lowest air densities of the Major League stadiums. Heat and humidity will cause baseballs to move more quickly out of the hand while the reduction in the Magnus force will cause them to break more poorly. And if fastballs get faster and curveballs break less, you can naturally expect to see more heaters in the game — and potentially more strikeouts as a result.
At the time of first pitch in Seattle, the Air Quality Index was 220. During the nine innings that followed, it would peak at 240 — more than twice the satisfactory level and “unhealthy for all groups.”
The year was 2020, and wildfires up and down the West Coast were making the empty stadiums even more apocalyptic. Shortly after smoke turned the Bay Area a dystopian orange, MLB decided to move home games from Seattle to San Francisco’s Oracle Park — because the air quality in the Pacific Northwest at that point was too unsafe for athletes.

It won’t be the last time baseball games are moved or even postponed due to air quality from fires. In 2022, perhaps against better judgment, the Mariners played the ALDS against the Astros when the AQI was 158. Though the unwritten rule is to postpone games when the AQI tops 200, players are beginning to push back, saying — rightfully — that prolonged exposure to inhaling smoke is dangerous. “It’s not like if you’re below 200, everything is fine, and if you’re above 200, everybody is severely affected,” a public health official pointed out to The Athletic. “There’s a whole continuum.”
If the Oakland Athletics move to Las Vegas, they’re all but certain to become the ninth Major League baseball team with at least the ability — if not the necessity — to play indoors.
In addition to the fully enclosed Tropicana Dome in Tampa Bay, seven stadiums currently have retractable roofs. And it is in the warmest, sunniest markets where those roofs most often remain closed: “Miami … played under an open roof just five times in the past two seasons — combined,” Fox Weather reports. The Rangers, meanwhile, replaced their only-26-year-old ballpark in 2019 because it had gotten literally too hot to play in Texas without air conditioning.
It’s not uncommon for the remaining open-air ballparks to top 95 degrees in the summer — a miserable experience for players and fans alike. Without covering more ballparks, injuries could climb and attendance could drop. “People might just say forget about it. I’m not going to a baseball game. It’s 105 degrees,” Brad Humphreys, professor of economics at West Virginia University, told Capital News Service.
Triple-A baseball introduced electronic strike zones this season, fueling speculation that the controversial robo-ump system could be coming to the Major Leagues next. But there is one big reason in favor of electronic strike zones that doesn’t often get mentioned in the debate: climate change.
A recent study found that “umpires call pitches less accurately in uncomfortable temperatures, with performance at its worst in extreme heat conditions,” Monmouth University writes. Incorrect calls were made at a rate of about 1% worse when temperatures topped 95 degrees. And while that might seem insignificant, “it is non-trivial for this high-revenue, high-stakes industry,” the study’s author, Monmouth associate professor of economics Eric Fesselmeyer, said. “Moreover, high temperatures cause an even greater decrease in accuracy on close-call pitches along the edges of the strike zone.”
Aggression and violence rise with the temperatures. In one study, violent crimes went up by as much as 5.7% on days with a maximum daily temperature above 85 degrees, and as much as 10% on days above about 88.
As dugouts and diamonds get hotter, tempers will too. But there is another reason to believe there will be more bench-clearing brawls beyond heat-induced short-fuses. According to a study published in the Personality and Social Psychology Bulletin in 1991, “a positive and significant relationship was found between temperature and the number of hit batters per game, even when potentially confounding variables having nothing to do with aggression were partialed out.”
Similarly, Duke University’s Fuqua School of Business found in 2011 that “pitchers whose teammates get hit by a pitch are more likely to retaliate and plunk an opposing batter when the temperature reaches 90 degrees than when it is cooler.” Curiously, if no one has been hit in a game, the study found “high temperatures have little effect on a pitcher’s behavior.” As one of the researchers put it, “heat affects a specific form of aggression. It increases retribution.”
Hurricane Ian — the category 4 hurricane that slammed southwest Florida last September — was the state’s costliest storm, inflicting $109 billion in damage including “totally” destroying 900 structures in Fort Meyers Beach alone. Among the damages: CenturyLink Sports Complex, the spring training facility of the Minnesota Twins; Fenway South, the Boston Red Sox’s facility; and Charlotte Sports Park, the Tampa Bay Rays’ spring training home, which sustained damage so extensive that the team had to find another stadium to practice in during the 2023 spring training season.
The lasting damage of the storm extends beyond the physical: “Hurricane Ian’s impact on Lee County likely played a role in depressing the crowds at Red Sox and Twins games this year,” Fort Myers News-Press reports.
There are no murmurs of moving the Grapefruit League’s spring training facilities — yet. But already the rising sea levels and storms of Florida are ruling out new stadium locations, including at least one potential regular-season home for the Rays. “Sites that once appeared to be great places to build a ballpark are now expected to be underwater,” the team president said. With climate already costing teams money and fans, as well as being a deciding factor in new builds, the Grapefruit League could prudently decide to uproot for higher grounds.
Homebuyers are taking into account the future climate conditions of potential properties, and if MLB is wise, it will do the same when considering team expansion.
From a climate standpoint, it already seems egregious to move a team to a desert city that is running out of drinkable water in the summer, though the Oakland A’s potential relocation to Las Vegas is still very much on the table. But when MLB looks at locations to expand to — Portland, Mexico City, North Carolina, Nashville, Montreal, and Vancouver have also been floated — the climate calculus becomes ever more important.
In 60 years, Portland will have a climate similar to Sacramento, complete with the threat of wildfire smoke. Mexico City is getting hotter, drier, and sinking. Charlotte and Raleigh will eventually “resemble the Florida panhandle, specifically Tallahassee, which is 12.6 °F warmer and 10.6% to 14.4% wetter than winter in Charlotte and Raleigh. Nashville is not too far, with Mobile, Alabama serving as its closest projection,” Fangraphs writes in an assessment of the future of ballparks in the climate crisis.
Unsurprisingly, with an eye for the future, it is the northernmost cities that look like the best options to withstand climate change impacts: “Vancouver and Montreal could look toward current day T-Mobile Park and Citizens Bank Park as examples of how to keep fans comfortable during games.”
Over the course of 12 months between 2019 and 2020, 10% of MLB teams switched from real grass to turf. “The three stadiums that replaced their grass share a lot in common,” wrote The Wall Street Journal at the time: “They play in cities with extreme weather and have retractable roofs.”
In Arizona, for example, real grass required sunlight — and thus an open roof — until between 4 p.m. and 7 p.m., which meant that players often worked out before games in temperatures of 110 degrees or more. By the time fans arrived, the building would still be sweltering, air conditioning not having yet kicked in. But by switching to turf, “the roof can remain closed all summer.”
Switching to turf also eliminates the demands of watering: Conservatively, about 62,500 gallons of water a week are required to maintain an average field, an amount 89 homes would use in the same amount of time. Though that water is likely negligible in the grand scheme of things, it’s important for teams to take “social responsibility” by “walking the walk,” Diamondbacks president and CEO Derrick Hall told The Associated Press.
Turf remains controversial — it can affect the bounce of balls and result in higher rates of injuries. Recent advances in turf technology, though, are making it more appealing for teams and the planet.
Anyone who’s ever watched nine innings of live baseball knows the kind of mess fans leave behind: peanut shell piles; beer cups; burger trays; plastic ice cream bowls shaped like hats; abandoned bobbleheads. Overall, baseball audiences create more than 1,000 tons of waste every season, according to the Green Sports Alliance.
A growing number of stadiums are now aspiring to contribute less to landfills, including by using compostable serving items and reducing food waste. But one place waste is still frequently overlooked is in promotional giveaways.
Every year, MLB gives away around four million bobbleheads in addition to other tchotchkes like branded visors, T-shirts, sunglasses, and bags. While some of these end up as treasured pieces of home collections, the vast majority are junk destined for landfills.
Though teams show no sign of forgoing giveaways anytime soon, the more environmentally conscious parks may begin to consider new ways of reducing their waste — including by curbing handouts of cheaply made petroleum products and environmentally taxing garments that no one actually needs.
Every year, athletes end up on the Injured List for reasons ranging from benign to ridiculous. Now there is a new reason to be pulled from a game: heat illness. During one 2018 game at Wrigley Field with a heat index of 107, four players ultimately left the field for temperature-related causes, including three who had to be treated with IV fluids. During another game in 2021, a 28-year-old pitcher vomited on the mound in New York City. Diagnosis? Heat exhaustion.
Normal sports injuries also spike as it gets warmer. “We always had what seemed to be a lot more soft-tissue leg injuries than some of the other clubs. Hamstrings, calf injuries, from guys running the bases,” a former Rangers trainer told The Atlantic in 2016, prior to the construction of the team’s new air-conditioned stadium. “Our staff attributed that to the excessive heat and the fatigue.”
The prevalence of naturally occurring injuries could go up too because as players get dehydrated, their brain, thought capacity, and reflexes “are affected and the player is not able to react immediately on the field,” a 2021 study by the International Journal of Physical Education found. “The player will be injured due to a fall or collision with another player or being hit by a ball.”
Tragically, rising temperatures also are known to contribute to an increased number of deaths, a pattern already observable in high school football. Baseball fans and minor league athletes have already died due to heat-related causes — an awful pattern that isn’t likely to abate.
In 2017, the mercury during the first game of the World Series in Los Angeles hit 103 degrees after 5 p.m.; the same year, the Oakland A’s Triple-A affiliate played in 111-degree heat in Las Vegas. On average, the temperature across the 27 Major League Baseball cities has risen over two degrees since 1970. And “the difference in home run rates between a 90-degree day and a 40-degree day is roughly equivalent to the difference between hitting in Citizens Bank Park” — which is small — “versus Citi Field,” which is comparatively huge, ESPN reports.
In our hotter, damper future, baseball will be a markedly different game than it was 50 years ago — or even now. Heat will affect players’ reflexes and focus. Balls will move differently through thinner, warmer air. Fielding could change ever so slightly as turf becomes more common, and pitchers might switch up their pitches as electronic strike zones come into use and curveballs become less effective.
All good statistical comparisons need context, and that is especially true in the ever-changing sport of baseball. But in the next century of the sport, it is all but certain that the literal environment of the games — from the weather to the air density to the AQI — will be a necessary asterisk beside unusual home runs and IL designations. One day, announcers may even reminisce about “open air” stadiums from their climate-controlled booths during downtime on broadcasts. Perhaps we’ll even have a name for the days of comparatively thicker air: the “cool-ball era.”

On a new report from the Energy Institute, high-stakes legislating, and accelerating nuclear development
Current conditions: Monsoon rains hit the southwestern U.S., with flash floods in Roswell, New Mexico, and flooding in El Paso, Texas • The Forsyth Fire in Utah has spread to 9,000 acres and is only 5% contained • While temperatures are falling into the low 80s in much of the Northeast, a high of 96 degrees Fahrenheit is forecast for Washington, D.C., where Republicans in the Senate seek to finish their work on the “One Big, Beautiful Bill.”
The world used more of just about every kind of energy source in 2024, including coal, oil, gas, renewables, hydro, and nuclear, according to the annual Statistical Review of World Energy, released by the Energy Institute. Here are some of the key numbers from the report:
You can read the full report here.
Virginia Republican Jen Kiggans is a vice chair of the Conservative Climate Caucus and a signatory of several letters supporting the preservation of clean energy tax credits in the Inflation Reduction Act, including one letter she co-authored with Pennsylvania’s Brian Fitzpatrick criticizing the House reconciliation bill’s rough approach to slashing the credits. On Wednesday, however, she said on X that the Senate language “responsibly phases out certain tax credits while preserving American investment and innovation in our energy sector.”
The Senate is still pushing to have the reconciliation bill on President Trump’s desk by July 4, and is expected to work through the weekend to get it done. But as Sahil Kapur of NBC News reported Wednesday, House and Senate leaders have been attempting to hash out yet another version of the bill that could pass both chambers quickly, meaning the legislation is still very much in flux.
Shell is in early talks to acquire fellow multinational oil giant BP, the Wall Street Journal reported. While BP declined to comment to the Journal, Shell called the story “market speculation” and said that “no talks are taking place.”
BP is currently valued at $80 billion, which would make a potential tie-up the largest corporate oil deal since the Exxon Mobil merger, according to the Journal.
Both Shell and BP have walked back from commitments to and investments in decarbonization and green energy in recent months. BP said in September of last year that it would divest from its U.S. wind business, while Shell said in January that it would “pause” its investment in the U.S. offshore wind industry and took an accompanying charge of $1 billion.
The combined company would be better positioned to compete with supermajors like Exxon, which is now worth over $450 billion, while Shell and BP have a combined valuation around $285 billion.

Three Mile Island Unit 1 will restart a year early, its owner Constellation said Wednesday. When Constellation and Microsoft announced the plan to restart the nuclear facility last fall they gave a target date of 2028. More recently, however, PJM Interconnection, the interstate electricity market that includes Pennsylvania, approved a request made from the state’s governor, Josh Shapiro, to fast-track the plant’s interconnection, the company said, meaning it could open as soon as 2027.
Constellation reported “significant progress” on hiring and training new workers, with around 400 workers either hired or due to start new jobs soon. “We’re on track to make history ahead of schedule, helping America achieve energy independence, supercharge economic growth, and win the global AI race,” Constellation’s chief executive Joe Dominguez said.
The Chinese electric carmarker BYD is addressing rising inventory and lower prices by cutting back its production plans. The company “has slowed its production and expansion pace in recent months by reducing shifts at some factories in China and delaying plans to add new production lines,” Reuters reported.
The slowdown comes “as it grapples with rising inventory even after offering deep price cuts in China's cutthroat auto market,” according to the Reuters report.
In 2024, BYD beat out Tesla in annual sales, with over 4 million cars sold, for a total annual revenue over $100 billion. Tesla’s revenue was just short of $100 billion last year.
While BYD’s factories may be slowing down, it is still looking to expand, especially overseas. In April, more than 7,000 BYD battery electric cars were registered in Europe, according to Bloomberg. This more-than-doubling since last year slingshotted BYD past Tesla on the continent, where its sales have fallen by almost 50%.
“Where does the power sector go from here?” an audience member asked at our exclusive Heatmap subscriber event in New York on Wednesday, referring to a potential future without the Inflation Reduction Act. “Higher costs,” Emily Pontecorvo answered. There is one potential bright spot, however, as Robinson Meyer explained: “If I were a Democrat considering running an affordability campaign or a cost-of-living campaign in ’26 or ’28, there’s lots of openings to talk about clean energy — the policy that’s happening right now — utility rates, and energy affordability.”
The science is still out — but some of the industry’s key players are moving ahead regardless.
The ocean is by far the world’s largest carbon sink, capturing about 30% of human-caused CO2 emissions and about 90% of the excess heat energy from said emissions. For about as long as scientists have known these numbers, there’s been intrigue around engineering the ocean to absorb even more. And more recently, a few startups have gotten closer to making this a reality.
Last week, one of them got a vote of confidence from leading carbon removal registry Isometric, which for the first time validated “ocean alkalinity enhancement” credits sold by the startup Planetary — 625.6 to be exact, representing 625.6 metric tons of carbon removed. No other registry has issued credits for this type of carbon removal.
When the ocean absorbs carbon, the CO2 in the air reacts with the water to form carbonic acid, which quickly breaks down into hydrogen ions and bicarbonate. The excess hydrogen increases the acidity of the ocean, changing its chemistry to make it less effective at absorbing CO2, like a sponge that’s already damp. As levels of atmospheric CO2 increase, the ocean is getting more acidic overall, threatening marine ecosystems.
Planetary is working to make the ocean less acidic, so that it can take in more carbon. At its pilot plant in Nova Scotia, the company adds alkalizing magnesium hydroxide to wastewater after it’s been used to cool a coastal power plant and before it’s discharged back into the ocean. When the alkaline substance (which, if you remember your high school chemistry, is also known as a base) dissolves in the water, it releases hydroxide ions, which combine with and neutralize hydrogen ions. This in turn reduces local acidity and raises the ocean’s pH, thus increasing its capacity to absorb more carbon dioxide. That CO2 is then stored as a stable bicarbonate for thousands of years.
“The ocean has just got such a vast amount of capacity to store carbon within it,” Will Burt, Planetary’s vice president of science and product, told me. Because ocean alkalinity enhancement mimics a natural process, there are fewer ecosystem concerns than with some other means of ocean-based carbon removal, such as stimulating algae blooms. And unlike biomass or soil-related carbon removal methods, it has a very minimal land footprint. For this reason, Burt told me “the massiveness of the ocean is going to be the key to climate relevance” for the carbon dioxide removal industry as a whole.
But that’s no guarantee. As with any open system where carbon can flow in and out, how much carbon the ocean actually absorbs is tricky to measure and verify. The best oceanography models we have still don’t always align with observational data.
Given this, is it too soon for Planetary to issue credits? It’s just not possible right now for the startup — or anyone in the field — to quantify the exact amount of carbon that this process is removing. And while the company incorporates error bars into its calculations and crediting mechanisms, scientists simply aren’t certain about the degree of uncertainty that remains.
“I think we still have a lot of work to do to actually characterize the uncertainty bars and make ourselves confident that there aren’t unknown unknowns that we are not thinking about,” Freya Chay, a program lead at CarbonPlan, told me. The nonprofit aims to analyze the efficacy of various carbon removal pathways, and has worked with Planetary to evaluate and inform its approach to ocean alkalinity enhancement.
Planetary’s process for measurement and verification employs a combination of near field observational data and extensive ocean modeling to estimate the rate, efficiency, and permanence of carbon uptake. Close to the point where it releases the magnesium hydroxide, the company uses autonomous sensors at and below the ocean’s surface to measure pH and other variables. This real-time data then feeds into ocean models intended to simulate large-scale processes such as how alkalinity disperses and dissolves, the dynamics of CO2 absorption, and ultimately how much carbon is locked away for the long-term.
But though Planetary’s models are peer-reviewed and best in class, they have their limits. One of the largest remaining unknowns is how natural changes in ocean alkalinity feed into the whole equation — that is, it’s possible that artificially alkalizing the ocean could prevent the uptake of naturally occurring bases. If this is happening at scale, it would call into question the “enhancement” part of alkalinity enhancement.
There’s also the issue of regional and seasonal variability in the efficiency of CO2 uptake, which makes it difficult to put any hard numbers to the efficacy of this solution overall. To this end, CarbonPlan has worked with the marine carbon removal research organization [C]Worthy to develop an interactive tool that allows companies to explore how alkalinity moves through the ocean and removes carbon in various regions over time.
As Chay explained, though, not all the models agree on just how much carbon is removed by a given base in a given location at a given time. “You can characterize how different the models are from each other, but then you also have to figure out which ones best represent the real world,” she told me. “And I think we have a lot of work to do on that front.”
From Chay’s perspective, whether or not Planetary is “ready” to start selling carbon removal credits largely depends on the claims that its buyers are trying to make. One way to think about it, she told me, is to imagine how these credits would stand up in a hypothetical compliance carbon market, in which a polluter could buy a certain amount of ocean alkalinity credits that would then allow them to release an equivalent amount of emissions under a legally mandated cap.
“When I think about that, I have a very clear instinctual reaction, which is, No, we are far from ready,”Chay told me.
Of course, we don’t live in a world with a compliance carbon market, and most of Planetary’s customers thus far — Stripe, Shopify, and the larger carbon removal coalition, Frontier, that they’re members of — have refrained from making concrete claims about how their voluntary carbon removal purchases impact broader emissions goals. But another customer, British Airways, does appear to tout its purchases from Planetary and others as one of many pathways it’s pursuing to reach net zero. Much like the carbon market itself, such claims are not formally regulated.
All of this, Chay told me, makes trying to discern the most responsible way to support nascent solutions all the more “squishy.”
Matt Long, CEO and co-founder of [C]Worthy, told me that he thinks it’s both appropriate and important to start issuing credits for ocean alkalinity enhancement — while also acknowledging that “we have robust reason to believe that we can do a lot better” when it comes to assessing these removals.
For the time being, he calls Planetary’s approach to measurement “largely credible.”
“What we need to adopt is a permissive stance towards uncertainty in the early days, such that the industry can get off the ground and we can leverage commercial pilot deployments, like the one that Planetary has engaged in, as opportunities to advance the science and practice of removal quantification,” Long told me.
Indeed, for these early-stage removal technologies there are virtually no other viable paths to market beyond selling credits on the voluntary market. This, of course, is the very raison d’etre of the Frontier coalition, which was formed to help emerging CO2 removal technologies by pre-purchasing significant quantities of carbon removal. Today’s investors are banking on the hope that one day, the federal government will establish a domestic compliance market that allows companies to offset emissions by purchasing removal credits. But until then, there’s not really a pool of buyers willing to fund no-strings-attached CO2 removal.
Isometric — an early-stage startup itself — says its goal is to restore trust in the voluntary carbon market, which has a history of issuing bogus offset credits. By contrast, Isometric only issues “carbon removal” credits, which — unlike offsets — are intended to represent a permanent drawdown of CO2 from the atmosphere, which the company defines as 1,000 years or longer. Isometric’s credits also must align with the registry’s peer-reviewed carbon removal protocols, though these are often written in collaboration with startups such as Planetary that are looking to get their methodologies approved.
The initial carbon removal methods that Isometric dove into — bio-oil geological storage, biomass geological storage, direct air capture — are very measurable. But Isometric has since branched beyond the easy wins to develop protocols for potentially less permanent and more difficult to quantify carbon removal methods, including enhanced weathering, biochar production, and reforestation.
Thus, the core tension remains. Because while Isometric’s website boasts that corporations can “be confident every credit is a guaranteed tonne of carbon removal,” the way researchers like Chay and Long talk about Planetary makes it sound much more like a promising science project that’s being refined and iterated upon in the public sphere.
For his part, Burt told me he knows that Planetary’s current methodologies have room for improvement, and that being transparent about that is what will ultimately move the company forward. “I am constantly talking to oceanography forums about, Here’s how we’re doing it. We know it’s not perfect. How do we improve it?” he said.
While Planetary wouldn’t reveal its current price per ton of CO2 removed, the company told me in an emailed statement that it expects its approach “to ultimately be the lowest-cost form” of carbon removal. Burt said that today, the majority of a credit’s cost — and its embedded emissions — comes from transporting bases from the company’s current source in Spain to its pilot project in Nova Scotia. In the future, the startup plans to mitigate this by co-locating its projects and alkalinity sources, and by clustering project sites in the same area.
“You could probably have another one of these sites 2 kilometers down the coast,” he told me, referring to the Nova Scotia project. “You could do another 100,000 tonnes there, and that would not be too much for the system, because the ocean is very quickly diluted.”
The company has a long way to go before reaching that type of scale though. From the latter half of last year until now, Planetary has released about 1,100 metric tons of material into the ocean, which it says will lead to about 1,000 metric tons of carbon removal.
But as I was reminded by everyone, we’re still in the first inning of the ocean alkalinity enhancement era. For its part, [C]Worthy is now working to create the data and modeling infrastructure that startups such as Planetary will one day use to more precisely quantify their carbon removal benefits.
“We do not have the system in place that we will have. But as a community, we have to recognize the requirement for carbon removal is very large, and that the implication is that we need to be building this industry now,” Long told me.
In other words: Ready or not, here we come.
On mercury rising, climate finance, and aviation emissions
Current conditions: Tropical Storm Andrea has become the first named Atlantic storm of 2025 • Hundreds of thousands are fleeing their homes in southwest China as heavy rains cause rivers to overflow • It’s hot and humid in New York’s Long Island City neighborhood, where last night New York City mayoral candidate Zohran Mamdani delivered his victory speech after defeating former governor and longtime party power broker Andrew Cuomo in the race’s Democratic primary.
The brutal heat dome baking the eastern half of the United States continues today. Cooler weather is in the forecast for tomorrow, but this heat wave has broken a slew of temperature records across multiple states this week:
In Washington, D.C., rail temperatures reached a blistering 135 degrees, forcing the city’s Metro to slow down train service. Meanwhile, in New Jersey, the heat sickened more than 150 people attending a high school graduation ceremony. As power demand surged, the Department of Energy issued an energy emergency in the Southeast to “help mitigate the risk of blackouts.”
As Heatmap’s Matthew Zeitlin pointed out on Tuesday, in terms of what is on the grid and what is demanded of it, this may be the easiest summer for a long time. “Demands on the grid are growing at the same time the resources powering it are changing,” Zeitlin writes. “Electricity load growth is forecast to grow several percent a year through at least the end of the decade. At the same time, aging plants reliant on oil, gas, and coal are being retired (although planned retirements are slowing down), while new resources, largely solar and batteries, are often stuck in long interconnection queues — and, when they do come online, offer unique challenges to grid operators when demand is high.”
A group of 21 Democrat-led states including New Jersey, Massachusetts, New York, Arizona, and California, is suing the Trump administration for cutting billions of dollars in federal funding, including grants related to climate change initiatives. The lawsuit says federal agencies have been “unlawfully invoking a single subclause” to cancel grants that the administration deems no longer align with its priorities. The clause in question states that federal agencies can terminate grants “pursuant to the terms and conditions of the federal award, including, to the extent authorized by law, if an award no longer effectuates the program goals or agency priorities.” The states accuse the administration of leaning on this clause for “virtually unfettered authority to withhold federal funding any time they no longer wish to support the programs for which Congress has appropriated funding.”
The rollback has gutted projects across states and nonprofits that support diversity, equity, and inclusion, as well as climate change preparation programs and research. The states say the clause is being used unlawfully, and hope a judge agrees. “These cuts are simply illegal,” said New York Attorney General Letitia James. “Congress has the power of the purse, and the president cannot cut billions of dollars of essential resources simply because he doesn’t like the programs being funded.”

A brief update from the Bonn Climate Change Conference in Germany: A group of 44 “Least Developed Countries” have called for rich countries to triple the financing goal for climate change adaptation by 2030 compared to 2022 levels. The current target sits at $40 billion a year by 2025, a number set back in 2021 at COP26. According toClimate Home News, tripling the financing goal on 2022 levels would bring in a little less than $100 billion annually. That’s far short of the $160 billion to $340 billion that the United Nations estimates will be needed by 2030. The Indian Express also reports that developing countries have “managed to force a reopening of discussions on the obligations of developed nations to ‘provide’ finance, and not just make efforts towards ‘mobilising’ financial resources, for climate action.” The issue will also be discussed at COP30 in Brazil later this year. The Bonn conference has been running since June 16 and ends tomorrow.
In the UK, aviation is now a bigger source of greenhouse gas emissions than the power sector, according to a new report from the Climate Change Committee. The independent climate advisors say that demand for leisure travel is boosting demand for international flights, and “continued emissions growth in this sector could put future targets at risk.” Meanwhile, the UK power sector has been rapidly decarbonizing, and is now the sixth largest source of emissions. (In the U.S., electricity production is the second-largest source of emissions, behind transportation.) The report also found that heat pump installations increased by 56% in 2024, and that nearly 20% of new vehicles sold were electric. UK emissions were down 50% last year compared to 1990.
The committee applauded the progress but urged more action from the government to cut electricity prices to help speed up the transition to clean technologies. “Our country is among a leading group of economies demonstrating a commitment to decarbonise society,” said Piers Forster, interim chair of the committee. “This is to be celebrated: delivering deep emissions reduction is the only way to slow global warming.”
Voters in North Carolina want Congress to leave the Inflation Reduction Act well enough alone, a new poll from Data for Progress finds. The survey, which asked North Carolina voters specifically about the clean energy and climate provisions in the bill, presented respondents with a choice between two statements: “The IRA should be repealed by Congress” and “The IRA should be kept in place by Congress.” (“Don’t know” was also an option.) The responses from voters broke down predictably along party lines, with 71% of Democrats preferring to keep the IRA in place compared to just 31% of Republicans, with half of independent voters in favor of keeping the climate law. Overall, half of North Carolina voters surveyed wanted the IRA to stick around, compared to 37% who’d rather see it go — a significant spread for a state that, prior to the passage of the climate law, was home to little in the way of clean energy development.
North Carolina now has a lot to lose with the potential repeal of the Inflation Reduction Act, as Heatmap’s Emily Pontecorvo has pointed out. The IRA brought more than 17,000 jobs to the state, along with $20 billion in investment spread out over 34 clean energy projects. Electric vehicle and charging manufacturers in particular have flocked to the state, with Toyota investing $13.9 billion in its Liberty EV battery manufacturing facility, which opened this past April.
As a fragile ceasefire between Israel and Iran takes hold, oil prices are now lower than they were before the conflict began on June 13.
