Editor's note: Kirk Smith, founder of the modern field of indoor air pollution studies, died last week at age 73 after suffering a stroke.
John Holdren, President Obama's science advisor and the Teresa and John Heinz Professor of Environmental Policy at Harvard University, was Smith's Ph.D advisor when the two were at the University of California, Berkeley. Holdren wrote this reminiscence as a letter to friends. We are republishing it here with Holdren's permission.
Kirk Smith, who was only three years younger than I am, became my first Ph.D. student shortly after I arrived at UC Berkeley in the summer of 1973, as a newly minted assistant professor, to launch the campus-wide graduate program in energy and resources (soon the Energy and Resources Group, ERG).
Kirk and I quickly became close friends, together with our life partners Cheri Holdren and Joan Diamond.
Some of the fondest early memories of our offspring, Craig and Jill Holdren and Nadia Diamond-Smith, were formed in joint activities of the two families. We explored the Berkeley hills together; walked the beaches of Point Reyes and Kailua together; backpacked together; snorkeled and scuba-dived together; and, of course, Kirk and I worked together on energy and environment projects big and small.
Kirk had three co-equal advisors for his doctoral dissertation. The other two were West Churchman of the Business School and Bob Spear of the School of Public Health. But even three of us were not enough to be wholly on top of the amazing breadth and depth of Kirk's scholarship.
The title of his dissertation was "The Interactions of Time and Technology: Propositions Suggested by an Examination of Coal and Nuclear Power, Hazard Indices, the Temporal Judgments of Law and Economics, and the Place of Time in Mind and Myth."
I kid you not.
When Kirk finished his Ph.D. in 1977, I connected him with one of my own most significant mentors, the geochemist and international scientific statesman Harrison Brown.
Harrison promptly hired Kirk to create the energy program at the Resource Systems Institute that Harrison had just founded at the East-West Center in Honolulu. Not long thereafter Kirk started his pioneering work on indoor air pollution from primitive stoves in poorly ventilated huts in the Third World, entailing months-long forays in the countrysides of South Asia, East Asia, and Latin America to make pollution measurements and, later, to track the health impacts that his pollution measurements indicated would be there. (They were.)
Kirk's work was the first to establish that the impacts of indoor air pollution on health worldwide were at least comparable to, and plausibly larger than, the impacts of outdoor air pollution.
Kirk was, in essence, the founding father of the now flourishing field of indoor air pollution studies, but that was hardly all he did. He made important contributions to understanding the causes, consequences, and equity implications of global climate change; the potential and limitations of biofuels; comparative environmental assessment of energy and non-energy hazards; and more.
His achievements were recognized by his appointment as Professor of Global Environmental Health and Chair of Environmental Health Sciences in the School of Public Health at UC Berkeley; Director of the Collaborative Clean Air Policy Center in Delhi; appointment to honorary professorships at universities in China, India, and Mongolia; election to the U.S. National Academy of Sciences and the International Academy of Indoor Air Sciences; award of both the Heinz Prize for Environment and the Tyler Prize for Environmental Achievement; and a share of the Nobel Peace Prize awarded in 2007 to the Intergovernmental Panel on Climate Change.
But all of that doesn't fully capture the person Kirk was.
The best compact picture I can offer is a line from the note that Cheri wrote to Joan shortly after Kirk passed away: "He was so very special, humane, funny, warm, brilliant…and leaves an enormous hole in our hearts and lives."
All who knew Kirk are poorer for his passing. As is the world.

“If we’re concerned about healthy pregnancies, focusing on the period before pregnancy may be even more important.”
Living near oil and gas operations, including fracking wells, is linked to stress and depression in people who are planning pregnancies, according to a new study.
Previous research has found that living near oil and gas operations is linked to physical and mental health problems during and after pregnancy including preterm birth, birth defects, low birth weights and increased stress. However, little research exists on the effects of preconception mental health. Some studies suggest that poor mental health during this time period is associated with increased odds of pregnancy complications.
The new study, conducted by researchers at the Boston University School of Public Health and published in the American Journal of Public Health, is the first to investigate how living near oil and gas operations affects mental health in people who are hoping to become pregnant.
“There are around 29 studies to date on associations between residential proximity to oil and gas development and adverse birth outcomes,” Mary D. Willis, lead author of the study and assistant professor at the Boston University School of Public Health, told EHN. “That body of work is very focused on the long-term health of infants, which is important, but this work adds to that literature by centering the potentially pregnant person.”
Willis and her colleagues looked at mental health survey data for 5,725 people, including residents across 37 U.S. states and Canadian provinces, who were planning to get pregnant. The study only included people with household incomes below $50,000 a year since they may not have the resources to move away from oil and gas operations if they wanted to.
They found that people who lived within roughly six miles of active oil and gas development were more likely to report moderate-to-severe depressive symptoms than people living 12 to 31 miles away, and that higher levels of active oil and gas activity were linked to higher reported levels of depression. They also found that the closer people lived to oil and gas operations, the higher the intensity of their stress levels.
While the study doesn’t prove that oil and gas operations cause stress and depression, researchers point to factors like changing economic and social dynamics and environmental degradation in communities with oil and gas development as factors that could impact mental health.
“Our findings lend credibility to the hypothesis that this industry, with its boom and bust cycles, brings economic, environmental and social hazards that lead to negative mental health outcomes,” Willis said.
“If we’re concerned about healthy pregnancies, focusing on the period before pregnancy may be even more important, and that time-frame is under-studied,” she added.
The study noted that many of the people in the study who reported elevated stress and depression symptoms lived further away from oil and gas operations than the minimum distance required in many states to protect people in homes, schools and healthcare facilities.

In Pennsylvania and Texas, for example, the two states with the highest rates of natural gas production, minimum “setback” distances are as small as 200 feet. Pennsylvania’s setback has been increased to 500 feet, but that only applies to newly constructed oil and gas wells.
The findings of the study imply that “these setback distances may not be big enough to protect population health and specifically mental health,” Willis said.
CAMERON PARISH, La. — Late into the night, John Allaire watches the facility next to his home shoot 300-foot flares from stacks.
He lives within eyesight of southwest Louisiana’s salty shores, where, for decades, he’s witnessed nearly 200 feet of land between it and his property line disappear into the sea. Two-thirds of the land was rebuilt to aid the oil and gas industry’s LNG expansion. LNG — shorthand for liquified natural gas – is natural gas that's cooled to liquid form for easier storage or transport; it equates to 1/600th the volume of natural gas in a gaseous state. It’s used to generate electricity, or fuel stove tops and home heaters, and in industrial processes like manufacturing fertilizer.
In the U.S., at least 30 new LNG terminal facilities have been constructed or proposed since 2016, according to the
Oil and Gas Watch project. Louisiana and Texas’ Gulf Coast, where five facilities are already operating, will host roughly two-thirds of the new LNG terminals – meaning at least 22 Gulf Coast LNG facilities are currently under construction, were recently approved to break ground or are under further regulatory review.
Although the U.S. didn’t ship LNG until 2016, when a freight tanker left, a few miles from where Cameron Parish’s LNG plants are today, last year the country became the global leader in LNG production and export volume, leapfrogging exporters like Qatar and Australia. The
EIA’s most recent annual outlook estimated that between the current year and 2050, U.S. LNG exports will increase by 152%.
Allaire, 68, watches how saltwater collects where rainwater once fed the area’s diminishing coastal wetlands. “We still come down here with the kids and set out the fishing rods. It's not as nice as it used to be,” he told
Environmental Health News (EHN).
That intimacy with nature drew Allaire to the area when he purchased 311 acres in 1998. An environmental engineer and 30-year oil and gas industry veteran, he helped lead environmental assessments and manage clean-ups, and although retired, he still works part-time as an environmental consultant with major petroleum companies. With a lifetime of oil and gas industry expertise, he’s watched the industry's footprint spread across Louisiana and the Gulf of Mexico’s fragile shores and beyond. Now that the footprints are at the edge of his backyard, Allaire is among a cohort of organizers, residents and fisher-folk in the region mobilizing to stop LNG facility construction. For him, the industry’s expansion usurps the right-or-wrong ethics he carried across his consulting career. For anglers, oil and gas infrastructure has destroyed fishing grounds and prevented smaller vessels from accessing the seafood-rich waters of the Calcasieu River.
From the view of Allaire’s white pickup truck as he drives across his property to the ocean’s shore, he points to where a new LNG facility will replace marshlands. Commonwealth LNG intends to clear the land of trees and then backfill the remaining low-lying field.
“You see what’s happening with the environment,” Allaire said. “When the facts change, I got to change my mind about what we’re doing.”

During an Earth Day rally in April, community members gathered in the urban center of Lake Charles to demand local oil and gas industries help deliver a safer, healthier future for all. In between live acts by artists performing south Louisiana’s quintessential zydeco musical style, speakers like James Hiatt, a Calcasieu Parish native with ties to Cameron Parish and a Healthy Gulf organizer, and RISE St. James organizer Sharon Lavigne, who’s fighting against LNG development in rural Plaquemines Parish near the city of New Orleans, asked the nearly 100 in attendance to imagine a day in which the skyline isn’t dotted by oil and gas infrastructure.
Not long ago, it was hard to imagine an Earth Day rally in southwest Louisiana at all. For decades, the area has been decorated with fossil fuel infrastructure. Sunsets on some days are highlighted by the chemicals in the air; at night, thousands of facilities’ lights dot the dark sky.
“It takes a lot of balls for people to start speaking up,” Shreyas Vasudevan, a campaign researcher with the Louisiana Bucket Brigade, told EHN in the days after the rally. In a region with its history and economy intertwined with oil and gas production, “you can get a lot of social criticism – or ostracization, as well – even threats to your life.”
Many are involved in local, regional and national advocacy groups, including the Louisiana Bucket Brigade, Healthy Gulf, the Sierra Club, the Natural Resources Defense Council, the Turtle Island Restoration Network, the Center for Biological Diversity and the National Audubon Society.

But environmental organizers are fighting a multi-billion-dollar industry with federal and state winds at its back. And LNG’s federal support is coupled with existing state initiatives.
Under outgoing Louisiana Gov. John Bel Edwards — a term-limited Democrat — the state pledged a goal of reaching net-zero greenhouse emissions by 2050. Natural gas, which the LNG industry markets as a cleaner-burning alternative, is cited as one of the state’s solutions. Louisiana is the only state that produces a majority of its carbon emissions through fossil fuels refining industries, like LNG, rather than energy production or transportation. Governor Edwards’ office did not return EHN’s request for comment.
This accommodating attitude towards oil and gas industries has resulted in a workforce that’s trained to work in LNG refining facilities across much of the rural Gulf region, said Steven Miles, a lawyer at Baker Botts LLP and a fellow at the Baker Institute’s Center on Energy Studies. Simultaneously, anti-industrialization pushback is lacking. It’s good news for industries like LNG.
“The bad news,” Miles added. “[LNG facilities] are all being jammed in the same areas.”
One rallying cry for opponents is local health. The Environmental Integrity Project found that LNG export terminals emit chemicals like carbon monoxide –potentially deadly– and sulfur dioxide, of which the American Lung Association says long-term exposure can lead to heart disease, cancer, and damage to internal or female reproductive organs.
An analysis of emissions monitoring reports by the advocacy group the Louisiana Bucket Brigade found that Venture Global’s existing Calcasieu Pass facility had more than 2,000 permit violations.That includes exceeding the permit’s authorized air emissions limit to release nitrogen oxides, carbon monoxide, particulate matter and volatile organic compounds 286 out of its first 343 days of operation.
The Marvel Crane, the first liquid natural gas carrier to transport natural gas from the Southwest Louisiana LNG facility, transits a channel in Hackberry, Louisiana, May 28, 2019.
“This is just one facility,” at a time when three more facilities have been proposed in the region and state, Vasudevan said. Venture Global’s operational LNG facility — also known as Calcasieu Pass — “is much smaller than the other facility they’ve proposed.”
In an area that experienced 18 feet of storm surge during Hurricane Laura in 2020 — and just weeks later, struck by Hurricane Delta — Venture Global is planning to build a second export terminal Known as “CP2,” it’s the largest of the roughly two dozen proposed Gulf LNG export terminals, and a key focal point for the region’s local organizing effort.
Residents “don’t really want LNG as much as they want Cameron [Parish] from 1990 back,” Hiatt told EHN of locals’ nostalgia for a community before storms like Rita in 2005 brought up to 15 feet of storm surge, only for Laura to repeat the damage in 2020. Throughout that time, the parish’s population dipped from roughly 10,000 to 5,000. “But the wolf knocking at the door is LNG. Folks in Cameron think that's going to bring back community, bring back the schools, bring back this time before we had all these storms — when Cameron was pretty prosperous.”
“Clearly,” for the oil and gas industry, “the idea is to transform what was once the center of commercial fishing in Louisiana to gas exports,” Cindy Robertson, an environmental activist in southwest Louisiana, told EHN.
Helping fishers’ impacted by LNG is about “actual survival of this unique culture,” Cooke said.
In a measure of organizers’ success, she pointed to a recent permit hearing for Venture Global’s CP2 proposal. Regionally, it’s the only project that’s received an environmental permit, but not its export permit, which remains under federal review. At the meeting, some spoke on the company’s behalf. As an organizer, it was a moment of clarity, Cooke explained. Venture Global officials “had obviously done a lot of coaching and organizing and getting people together in Cameron to speak out on their behalf,” Cooke said. “So, in a way, that was bad. But in another way, it shows that we really had an impact.”
“It also shows that we have a lot to do,” Cooke added.
Environmental organizers like Alyssa Portaro describe a sense of fortitude among activists — she and her husband to the region’s nearby town of Vinton near the Texas-Louisiana border. Since the families’ relocation to their farm, Portaro has worked with Cameron Parish fisher-folk.
“I’ve not witnessed ‘community’ anywhere like there is in Louisiana,” Portaro told EHN. But a New Jersey native, she understands the toll environmental pollution has on low-income communities. “This environment, it’s so at risk — and it’s currently getting sacrificed to big industries.”
“People don’t know what we’d do without oil and gas. It comes at a big price,” she added.
Southwest Louisiana’s Cameron Parish is one of the state’s most rural localities. Marine economies were the area’s economic drivers until natural disasters and LNG facilities began pushing locals out, commercial fishers claim.

A disappearing parish
The stakes are seemingly higher for a region like southwest Louisiana, which is the epicenter of climate change impacts.
In nearly a century, the state has lost roughly 2,000 square miles of land to coastal erosion. In part driving the state’s erosion crisis is the compounding impacts of Mississippi River infrastructure and oil and gas industry activity, such as dredging canals for shipping purposes, according to a March study published in the journal Nature Sustainability. Louisiana’s Coastal Protection and Restoration Authority said Cameron Parish could lose more land than other coastal parishes over the next 50 years. A recent Climate Central report says the parish will be underwater within that time frame.
On top of erosion and sea level rise impacts, in August, 2023, marshland across southwest Louisiana’s Cameron Parish burned. The fires were among at least 600 across the Bayou State this year. Statewide, roughly 60,000 acres burned — a more than six-fold increase of the state’s average acres burned per year in the past decade alone.
But while the blaze avoided coastal Louisiana communities like Cameron Parish, the fires represented a warning coming from a growing chorus of locals across the region — one that’s echoes by the local commercial fishing population, who claimed to have experienced unusually low yields during the same time, according to a statement from a local environmental group. At the site of the Cameron Parish fires are locations for two proposed LNG expansion projects.
"The idea is to transform what was once the center of commercial fishing in Louisiana to gas exports.” - Cindy Robertson, an environmental activist in southwest Louisiana
It was an unusual occurrence for an area that’s more often itself underwater this time of year due to a storm surge from powerful storms. For LNG expansion’s local opposition, it was a red flag.
As the Louisiana Bucket Brigade has noted prior, the confluence of climate change’s raising of sea levels and the construction of LNG export terminals — some are proposed at the size of nearly 700 football fields — are wiping away the marshland folks like Allaire watched wither. Among their fears is that the future facilities won’t be able to withstand the power of another storm like Laura and its storm surge, which wiped away entire communities in 2020.
Amidst these regional climate impacts, LNG infrastructure has shown potential to exacerbate the accumulation of greenhouse gasses that cause global warming. For the most part, LNG is made up of methane — a greenhouse gas that’s more than 80 times more potent than carbon dioxide in the atmosphere. Among the 22 current LNG facility proposals, the advocacy group Sierra Club described a combined climate pollution output that would roughly equal to that of about 440 coal plants.
The climate impacts prompt some of the LNG industry’s uncertainty going forward. It isn’t clear if Asian countries, key importers of U.S. LNG, will “embrace these energy transition issues,” said David Dismuke, an energy consultant and the former executive director of Louisiana State University’s Center for Energy Studies. Likewise, European nations remain skeptical of embracing LNG as a future staple fuel source.
“They really don't want to have to pull the trigger,” Dismukes added, referring to Europe’s hesitation to commit more resources to exporting LNG from the American market. “They don't want to go down that road.”
While there will be a tapering down of natural gas supply, Miles explained, “we’re going to need natural gas for a long time,” as larger battery storage for renewables is still unavailable.
“I'm not one of these futurists that can tell you where we're going to be, but I just don't see everything being extreme,” Dismukes said. “I don't see what we've already built getting stranded and going away, either.”
For now, LNG seems here to stay. From 2012 to 2022,U.S. natural gas demand — the sum of both domestic consumption and gross exports — rose by a whopping 43%, reported the U.S. Energy Information Administration, or EIA. Meanwhile, in oil and gas hotbeds like Louisiana and Texas, natural gas demand grew by 116%.
Throughout 25 years, Allaire has witnessed southwest Louisiana’s land slowly fade, in part driven by the same industrial spread regionally. Near where the front door of his travel trailer sits underneath the aluminum awning, he points to a chenier ridge located near the end of the property. It’s disappearing, he said.
“See the sand washing over, in here?” Allaire says, as he points towards the stretches of his property. “This pond used to go down for a half mile. This is all that's left of it on this side.”
Monday set a new global temperature record, surpassing the previous day’s high, as extreme heat continues to affect countries worldwide, according to European climate data.
Monday’s global average temperature was 17.15 degrees Celsius, beating Sunday’s record by 0.06 degrees.
Climate scientists attribute the heat to human-caused climate change, with temperatures now matching levels from 125,000 years ago.
The recent heatwave was intensified by an unusually warm Antarctic winter.

Why this matters:
Rising global temperatures threaten ecosystems, human health and economies. Without immediate changes in energy policies, extreme weather events will become more frequent and severe.
The first landslide struck Geze district, killing many villagers; a second landslide hit rescuers an hour later.
Continuous heavy rains had saturated the land, leading to the deadly mudslides.
The region is increasingly vulnerable to climate change, experiencing severe weather patterns and more frequent natural disasters.

“They had no clue that the land they were standing on was about to swallow them.”
— Habtamu Fetena, local government emergency response head
Why this matters:
Climate change is intensifying extreme weather events in East Africa, leading to more frequent and severe natural disasters. Understanding these impacts is crucial for improving disaster preparedness and response
Paris 2024 will use existing venues and low-carbon construction for new sites to minimize environmental impact.
The Games will feature extensive use of recycled materials, plant-based food and local agriculture.
Transport will prioritize electric connections and cycling infrastructure to reduce emissions.
Why this matters:
Sustainable practices at large events like the Olympics can set a global standard, encouraging broader environmental responsibility. Addressing carbon footprints is crucial to combating climate change and preserving the planet for future generations.
A Philippine oil tanker sank in Manila Bay, potentially causing a major spill, after being battered by waves, prompting the coast guard to rescue 16 of 17 crew members.
The Terra Nova, carrying 1.4 million liters of industrial fuel, sank after battling huge waves.
Aerial surveys show a 2.3-mile oil spill near the sinking site, but it might be engine fuel, not cargo oil.
The coast guard is preparing for potential shoreline contamination in Manila and considering siphoning the fuel.
Key quote:
“There’s a big danger that Manila would be affected, its shorelines, if the fuel leaks because this happened within Manila Bay. It’s part of the contingency we’re preparing for. The effect on the marine environment would not be good.”
California regulators decided they lack the authority to enforce the state's new oil well cleanup law on California's largest oil company merger, potentially costing taxpayers billions.
California’s new oil well cleanup law, passed in October, requires companies to set aside bonds to cover cleanup costs during well transfers.
State regulators ruled the law doesn't apply to the merger of California Resources Corp. and Aera Energy, which involves about 16,000 idle wells.
Critics argue this interpretation creates a loophole allowing companies to evade the law’s financial requirements.
Key quote:
“If a company is drilling for oil in California, they should be responsible for cleaning and closing that oil well. Not enforcing the law as intended sets-up our state for a potential financial catastrophe.”
Power shutoffs or wildfire evacuations can be deadly for disabled people, especially nondrivers who may not have a way to get to a cooling center or evacuation point.
