CLIMATEWIRE | Floods could be deadlier than previously thought — and from more than just drowning.

A study published Tuesday in Nature found that the number of U.S. deaths in flooded areas continued to rise for up to three months after the disaster, resulting in a 25 percent higher death rate from things like infections, injuries and heart disease, compared with periods of no flooding.

The researchers from Columbia University used a statistical model to analyze national death data from 2001 to 2018 and calculate how death rates changed in the three months following floods versus normal conditions.

They found that the residents of 2,711 counties experienced floods during that time frame, with heavy rain and snowmelt being the top causes of flooding.

“Our results show that floods were associated with higher death rates for most major causes of death, even for rain- and snow-related floods that are less likely to generate rapid emergency responses” than hurricanes, said author Victoria Lynch, a postdoctoral research fellow at the Columbia Mailman School of Public Health.

In particular, the researchers found that rain-related flooding was associated with increased deaths from infectious diseases, while flooding from melting snow was associated with higher death rates from respiratory and cardiovascular diseases.

“There is a hidden burden of exposure to floods that people may not be thinking about having an effect over time,” said author Robbie Parks, assistant professor of environmental health sciences at Columbia. “There is a big infection issue, but even the indirect effects of flooding adding stress can have an impact on cardiovascular health.”

From Greenland to Ghana, Indigenous youth work for climate justice

“No matter what happens we will stand and we will fight, and we will keep pushing for solutions.”

For the last week,  Indigenous leaders from around the world have converged in New York for the United Nations Permanent Forum on Indigenous Issues, or UNPFI. It’s the largest global gathering of Indigenous peoples and the Forum provides space for participants to bring their issues to international authorities, often when their own governments have refused to take action. This year’s Forum focuses on how U.N. member states’ have, or have not, protected the rights of Indigenous peoples, and conversations range from the environmental effects of extractive industries, to climate change, and violence against women. The Forum is an intergenerational space. Young people in attendance often work alongside elders and leaders to come up with solutions and address ongoing challenges. Grist interviewed seven Indigenous youth attending UNPFII this year hailing from Africa, the Pacific, North and South America, Asia, Eastern Europe, and the Arctic. Joshua Amponsem, 33, is Asante from Ghana and the founder of Green Africa Youth Organization, a youth-led group in Africa that promotes energy sustainability. He also is the co-director of the Youth Climate Justice Fund which provides funding opportunities to bolster youth participation in climate change solutions.  Since the Trump administration pulled all the funding from the U.S. Agency for International Development, or USAID, Amponsem has seen the people and groups he works with suffer from the loss of financial help. Courtesy of Joshua Amponsem It’s already hard to be a young person fighting climate change. Less than one percent of climate grants go to youth-led programs, according to the Youth Climate Justice Fund.   “I think everyone is very much worried,” he said. “That is leading to a lot of anxiety.”  Amponsem specifically mentioned the importance of groups like Africa Youth Pastoralist Initiatives — a coalition of youth who raise animals like sheep or cattle. Pastoralists need support to address climate change because the work of herding sheep and cattle gets more difficult as drought and resource scarcity persist, according to one report.  “No matter what happens we will stand and we will fight, and we will keep pushing for solutions,” he said. Janell Dymus-Kurei, 32, is Māori from the East Coast of Aotearoa New Zealand. She is a fellow with the Commonwealth Fund, a group that promotes better access to healthcare for vulnerable populations. At this year’s UNPFII, Dymus-Kurei hopes to bring attention to legislation aimed at diminishing Māori treaty rights. While one piece of legislation died this month, she doesn’t think it’s going to stop there. She hopes to remind people about the attempted legislation that would have given exclusive Maori rights to everyone in New Zealand. Courtesy of Janell Dymus-Kurei The issue gained international attention last Fall when politician Hana-Rawhiti Maipi-Clarke performed a Haka during parliament, a traditional dance that was often done before battle. The demonstration set off other large-scale Māori protests in the country.  “They are bound by the Treaty of Waitangi,” she said. Countries can address the forum, but New Zealand didn’t make it to the UNPFII.  “You would show up if you thought it was important to show up and defend your actions in one way, shape, or form,” she said. This year, she’s brought her two young children — TeAio Nitana, which means “peace and divinity” and Te Haumarangai, or “forceful wind”. Dymus-Kurei said it’s important for children to be a part of the forum, especially with so much focus on Indigenous women. “Parenting is political in every sense of the word,” she said. Avery Doxtator, 22, is Oneida, Anishinaabe and Dakota and the president of the National Association of Friendship Centres, or NAFC, which promotes cultural awareness and resources for urban Indigenous youth throughout Canada’s territories. She attended this year’s Forum to raise awareness about the rights of Indigenous peoples living in urban spaces. The NAFC brought 23 delegates from Canada this year representing all of the country’s regions. It’s the biggest group they’ve ever had, but Doxtator said everyone attending was concerned when crossing the border into the United States due to the Trump Administration’s border and immigration restrictions. Taylar Dawn Stagner “It’s a safety threat that we face as Indigenous peoples coming into a country that does not necessarily want us here,” she said. “That was our number one concern. Making sure youth are safe being in the city, but also crossing the border because of the color of our skin.” The United Nations Declaration on the Rights of Indigenous Peoples, or UNDRIP, protects Indigenous peoples fundamental rights of self-determination, and these rights extend to those living in cities, perhaps away from their territories. She said that she just finished her 5th year on the University of Toronto’s Water Polo Team, and will be playing on a professional team in Barcelona next year.  Around half of Indigenous peoples in Canada live in cities. In the United States around 70 percent live in cities. As a result, many can feel disconnected from their cultures, and that’s what she hopes to shed light on at the forum — that resources for Indigenous youth exist even in urban areas. Liudmyla Korotkykh, 26, is Crimean Tatar from Kyiv, one of the Indigenous peoples of Ukraine. She spoke at UNPFII about the effects of the Ukraine war on her Indigenous community. She is a manager and attorney at the Crimean Tatar Resource Center. The history of the Crimean Tatars are similar to other Indigenous populations. They have survived colonial oppression from both the Russian Empire and the Soviet Union — and as a result their language and way of life is constantly under threat. Crimea is a country that was annexed by Russia around a decade ago.  Taylar Dawn Stagner In 2021, President Zelensky passed legislation to establish better rights for Indigenous peoples, but months later Russia continued its campaign against Ukraine.  Korotkykh said Crimean Tatars have been conscripted to fight for Russia against the Tatars that are now in Ukraine.  “Now we are in the situation where our peoples are divided by a frontline and our peoples are fighting against each other because some of us joined the Russian army and some joined the Ukrainian army,” she said.  Korotkykh said even though many, including the Trump Administration, consider Crimea a part of Russia, hopes that Crimean Tatars won’t be left out of future discussions of their homes.  “This is a homeland of Indigenous peoples. We don’t accept the Russian occupation,” she said. “So, when the [Trump] administration starts to discuss how we can recognize Crimea as a part of Russia, it is not acceptable to us.” Toni Chiran, 30, is Garo from Bangladesh, and a member of the Bangladesh Indigenous Youth Forum, an organization focused on protecting young Indigenous people. The country has 54 distinct Indigenous peoples, and their constitution does not recognize Indigenous rights.  In January, Chiran was part of a protest in Dhaka, the capital of Bangladesh, where he and other Indigenous people were protesting how the state was erasing the word “Indigenous” — or Adivasi in Hindi — from text books. Chiran says the move is a part of an ongoing assault by the state to erase Indigenous peoples from Bangladesh. Courtesy of Toni Chiran He said that he sustained injuries to his head and chest during the protest as counter protesters assaulted their group, and 13 protesters sustained injuries. He hopes bringing that incident, and more, to the attention of Forum members will help in the fight for Indigenous rights in Bangladesh. “There is an extreme level of human rights violations in my country due to the land related conflicts because our government still does not recognize Indigenous peoples,” he said.  The student group Students for Sovereignty were accused of attacking Chiran and his fellow protesters. During a following protest a few days later in support of Chiran and the others injured Bangladesh police used tear gas and batons to disperse the crowd.  “We are still demanding justice on these issues,” he said. Aviaaija Baadsgaard, 27, is Inuit and a member of the Inuit Circumpolar Council Youth Engagement Program, a group that aims to empower the next generation of leaders in the Arctic. Baadsgaard is originally from Nuunukuu, the capital of Greenland, and this is her first year attending the UNPFII. Just last week she graduated from the University of Copenhagen with her law degree. She originally began studying law to help protect the rights of the Inuit of Greenland.. Recently, Greenland has been a global focal point due to the Trump Administration’s interest in acquiring the land and its resources – including minerals needed for the green transition like lithium and neodymium: both crucial for electric vehicles. “For me, it’s really important to speak on behalf of the Inuit of Greenland,” Baadsgaard said. Taylar Dawn Stagner Greenland is around 80 percent Indigenous, and a vast majority of the population there do not want the Greenland is around 80 percent Indigenous, and a vast majority of the population there do not want the U.S. to wrest control of the country from the Kingdom of Denmark. Many more want to be completely independent.  “I don’t want any administration to mess with our sovereignty,” she said.  Baadsgaard said her first time at the forum has connected her to a broader discussion about global Indigenous rights — a conversation she is excited to join. She wants to learn more about the complex system at the United Nations, so this trip is about getting ready for the future. Cindy Sisa Andy Aguinda, 30, is Kitchwa from Ecuador in the Amazon. She is in New York to talk about climate change, women’s health and the climate crisis. She spoke on a panel with a group of other Indigenous women about how the patriarchy and colonial violence affect women at a time of growing global unrest. Especially in the Amazon where deforestation is devastating the forests important to the Kitchwa tribe.  She said international funding is how many protect the Amazon Rainforest. As an example, last year the United States agreed to send around 40 million dollars to the country through USAID — but then the Trump administration terminated most of the department in March. Courtesy of Cindy Sisa Andy Aguinda “To continue working and caring for our lands, the rainforest, and our people, we need help,” she said through a translator. Even when international funding goes into other countries for the purposes to protect Indigenous land, only around 17 percent ends up in the hands of Indigenous-led initiatives. “In my country, it’s difficult for the authorities to take us into account,” she said.  She said despite that she had hope for the future and hopes to make it to COP30 in Brazil, the international gathering that addresses climate change, though she will probably have to foot the bill herself. She said that Indigenous tribes of the Amazon are the ones fighting everyday to protect their territories, and she said those with this relationship with the forest need to share ancestral knowledge with the world at places like the UNPFII and COP30.  “We can’t stop if we want to live well, if we want our cultural identity to remain alive,” she said.

Harris County commissioners approve climate justice plan

Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control.

Sarah GrunauFlood waters fill southwest Houston streets during Hurricane Beryl on July 8, 2024.Harris County commissioners this month approved what’s considered the county’s most comprehensive climate justice plan to date. Nearly three years in the works, the Harris County Climate Justice Plan is a 59-page document that creates long-term strategies addressing natural resource conservation, infrastructure resiliency and flood control in the Houston area. The climate justice plan was created by the Office of County Administration’s Office of Sustainability and an environmental nonprofit, Coalition for Environment, Equity and Resilience. The plan sets goals in five buckets, said Stefania Tomaskovic, the coalition director for the nonprofit. Those include ecology, infrastructure, economy, community and culture. County officials got feedback from more than 340 residents and organizations to ensure the plans reflect the needs of the community. “We held a number of community meetings to really outline the vision and values for this process and then along the way we’ve integrated more and more community members into the process of helping to identify the major buckets of work,” Tomaskovic told Hello Houston. Feedback from those involved in the planning process of the climate justice plan had a simple message — people want clean air, strong infrastructure in their communities, transparency and the opportunity to live with dignity, according to the plan. It outlines plans to protect from certain risks through preventative floodplain and watershed management, land use regulations and proactive disaster preparation. Infrastructure steps in the plan include investing in generators and solar power battery backup, and expanding coordination of programs that provide rapid direct assistance after disasters. Economic steps in the plan including expanding resources with organizations to support programs that provide food, direct cash assistance and housing. Tomaskovic said the move could be cost effective because some studies show that for every dollar spent on mitigation, you’re actually saving $6. “It can be cost effective but also if you think about, like, the whole line of costs, if we are implementing programs that help keep people out of the emergency room, we could be saving in the long run, too,” she said. Funds that will go into implementing the projects have yet to be seen. The more than $700,000 climate plan was funded by nonprofit organizations, including the Jacob & Terese Hershey Foundation. “Some of them actually are just process improvements,” Lisa Lin, director of sustainability with Harris County, told Hello Houston. “Some of them are actually low-cost, no-cost actions. Some of them are kind of leaning on things that are happening in the community or happening in the county. Some of them might be new and then we’ll be looking at different funding sources.” The county will now be charged with bringing the plan into reality, which includes conducting a benefits and impacts analysis. County staffers will also develop an implementation roadmap to identify specific leaders and partners and a plan to track its success, according to the county. “This initiative is the first time a U.S. county has prepared a resiliency plan that covers its entire population, as opposed to its bureaucracy alone," Harris County Judge Lina Hidalgo said in a statement. "At the heart of this plan are realistic steps to advance issues like clean air, resilient infrastructure, and housing affordability and availability. Many portions of the plan are already in progress, and I look forward to continued advancement over the years."

A forthcoming Supreme Court decision could limit agencies’ duty to consider environmental harms

The ruling could allow federal agencies to skip climate analysis when approving major projects — with wide-reaching consequences.

A forthcoming Supreme Court decision is poised to weaken a bedrock law that requires federal agencies to study the potential environmental impacts of major projects. The case, Seven County Infrastructure Coalition v. Eagle County, Colorado, concerns a proposed 88-mile railroad that would link an oil-producing region of Utah to tracks that reach refineries in the Gulf Coast. Environmental groups and a Colorado county argued that the federal Surface Transportation Board failed to adequately consider climate, pollution, and other effects as required under the National Environmental Protection Act, or NEPA, in approving the project. In 2023, the District of Columbia Circuit Court of Appeals ruled in favor of the challengers. The groups behind the railway project, including several Utah counties, appealed the case to the highest court, which is expected to hand down a decision within the next few months.  Court observers told Grist the Supreme Court will likely rule in favor of the railway developers, with consequences far beyond Utah. The court could limit the scope of environmental harms federal agencies have to consider under NEPA, including climate impacts. Depending on how the justices rule, the decision could also bolster — or constrain — parallel moves by the Trump administration to roll back decades-old regulations governing how NEPA is implemented. “All of these rollbacks and attacks on NEPA are going to harm communities, especially those that are dealing with the worst effects of climate change and industrial pollution,” said Wendy Park, senior attorney at the nonprofit Center for Biological Diversity, a party in the Supreme Court case.  Since 1970, NEPA has required federal agencies to take a “hard look” at the environmental effects of proposed major projects or actions. Oil and gas pipelines, dams, mines, highways, and other infrastructure projects must undergo an environmental study before they can get federal permits, for example. Agencies consider measures to reduce potential impacts during their review and can even reject a proposal if the harms outweigh the benefits.  NEPA ensures that environmental concerns are “part of the agenda” for all federal agencies — even ones that don’t otherwise focus on the environment, said Dan Farber, a law professor at the University of California Berkeley. It’s also a crucial tool for communities to understand how a project will affect them and provide input during the decision-making process, according to Park.  Oil tanker railway cars in Albany, New York, in 2014. John Carl D’Annibale / Albany Times Union via Getty Images In 2021, the Surface Transportation Board, a small federal agency that oversees railways, approved a line that would connect the Uinta Basin to the national rail network. The basin, which contains large deposits of crude oil, spans about 12,000 square miles across northeastern Utah and northwestern Colorado and is currently accessible only by truck. The proposed track would allow companies to transport crude oil to existing refineries along the Gulf Coast, quadrupling waxy crude oil production in the basin. According to the agency’s environmental review, under a high oil production scenario, burning those fuels “could represent up to approximately 0.8 percent of nationwide emissions and 0.1 percent of global emissions” — about 30 million tons of carbon dioxide a year. Environmental groups and a Colorado county challenged the board’s approval at the D.C. Circuit Court. The groups argued that the agency had failed to consider key impacts in its NEPA review, including the effects of increased oil refining on communities already burdened by pollution along the Gulf Coast of Louisiana and Texas, and the potential for more oil spills and wildfires along the broader rail network. In August 2023, the D.C. Circuit largely agreed, finding “numerous NEPA violations” in the agency’s environmental review. In their appeal to the Supreme Court, the developers of the railway initially argued that an agency shouldn’t have to consider any environmental effects of a project that would fall under the responsibility of a different agency. In this case, for example, the Surface Transportation Board wouldn’t have to consider air pollution impacts of oil refining on Gulf Coast communities because the Environmental Protection Agency, not the Surface Transportation Board, regulates air pollution.  By oral arguments in December, however, the railway backers had walked away from this drastic interpretation, which contradicts decades of NEPA precedent. It’s standard practice for one agency’s environmental review to study impacts that fall under the responsibility of other agencies, said Deborah Sivas, a law professor at Stanford University. The railway proponents instead proposed that agencies shouldn’t have to consider impacts that fall outside of their authority and are “remote in time and space.” That would include the effects on Gulf Coast communities residing thousands of miles away — as well as climate impacts like greenhouse gas emissions. Park, from the Center for Biological Diversity, argued that overlooking those impacts would undermine the intent of NEPA, which is to inform the public of likely harms. “The entire purpose of this project is to ramp up oil production in Utah and to deliver that oil to Gulf Coast refineries,” she said. “To effectively allow the agency to turn a blind eye to that purpose and ignore all of the predictable environmental harms that would result from that ramped-up oil production and downstream refining is antithetical to NEPA’s purpose.”  Lawyers for the railway’s developers didn’t respond to Grist’s request for comment. A coalition of Utah counties backing the project has previously underlined the economic potential of the project. “We are optimistic about the Supreme Court’s review and confident in the thorough environmental assessments conducted by the STB,” said Keith Heaton, director of the Seven County Infrastructure Coalition, said in a statement after the Supreme Court agreed to hear the case. “This project is vital for the economic growth and connectivity of the Uinta Basin region, and we are committed to seeing it through.” The Supreme Court has historically always ruled in favor of the government in NEPA cases, and legal experts told Grist the decision will likely support the railway developers in some manner. But during oral arguments, several justices seemed skeptical of positions presented by railway supporters. Chief Justice John Roberts noted that imposing such severe limits on NEPA review could open agencies up to legal risk.  Supreme Court Chief Justice John Roberts poses for an official portrait in 2022. Alex Wong / Getty Images The court could reach some kind of middle ground in its decision — not going as far as the D.C. Circuit to affirm the legitimacy of considering a wide range of climate and other risks, but also not excluding as many impacts as the railway developers had hoped, said Farber.  Any decision will ultimately serve as an important guide for agencies as the Trump administration introduces even more uncertainty in the federal permitting process. In February, the administration issued an interim rule to rescind regulations issued by the White House Council on Environmental Quality, which oversees NEPA implementation across the federal government. The council’s rules have guided agencies in applying the law for nearly five decades. Now, Trump officials have left it up to each individual agency to develop its own regulations by next February.  In developing those standards, agencies will likely look to the Supreme Court’s decision, legal experts said. “What the Supreme Court rules here could be a very important guide as to how agencies implement NEPA and how they fashion their regulations interpreting NEPA,” said Park. If the court rules that agencies don’t need to consider climate impacts in NEPA reviews, for example, that could make it easier for Trump appointees to ignore greenhouse gas emissions, said Sivas. The White House has already instructed agencies not to include environmental justice impacts in their assessments. On the other hand, a more nuanced opinion by the Supreme Court could end up undercutting efforts by the Trump administration to limit the scope of environmental reviews, said Farber. If justices end up affirming the need to consider certain impacts of the Utah railway project, for example, that could limit how much agencies under Trump can legally avoid evaluating particular effects. Agencies need to design regulations that will withstand challenges in lower courts — which will inevitably rely on the Supreme Court’s ruling when deciding on NEPA challenges moving forward. In the meantime, however, legal experts say that Trump’s decision to have each agency create its own NEPA regulations will create even more chaos and uncertainty, even as the administration seeks to “expedite and simplify the permitting process” through sweeping reforms.  “I think that’s going to just slow down the process more and cause more confusion, and not really serve their own goals,” said Farber.

The World's Biggest Companies Have Caused $28 Trillion in Climate Damage, a New Study Estimates

A new study estimates that the world’s biggest corporations have caused $28 trillion in climate damage, which is a shade less than the sum of all goods and services produced in the United States last year

WASHINGTON (AP) — The world's biggest corporations have caused $28 trillion in climate damage, a new study estimates as part of an effort to make it easier for people and governments to hold companies financially accountable, like the tobacco giants have been.A Dartmouth College research team came up with the estimated pollution caused by 111 companies, with more than half of the total dollar figure coming from 10 fossil fuel providers: Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation.For comparison, $28 trillion is a shade less than the sum of all goods and services produced in the United States last year.At the top of the list, Saudi Aramco and Gazprom have each caused a bit more than $2 trillion in heat damage over the decades, the team calculated in a study published in Wednesday's journal Nature. The researchers figured that every 1% of greenhouse gas put into the atmosphere since 1990 has caused $502 billion in damage from heat alone, which doesn't include the costs incurred by other extreme weather such as hurricanes, droughts and floods.The study is an attempt to determine “the causal linkages that underlie many of these theories of accountability,” said its lead author, Christopher Callahan, who did the work at Dartmouth but is now an Earth systems scientist at Stanford University. The research firm Zero Carbon Analytics counts 68 lawsuits filed globally about climate change damage, with more than half of them in the United States.“Everybody’s asking the same question: What can we actually claim about who has caused this?” said Dartmouth climate scientist Justin Mankin, co-author of the study. “And that really comes down to a thermodynamic question of can we trace climate hazards and/or their damages back to particular emitters?”The answer is yes, Callahan and Mankin said.The researchers started with known final emissions of the products — such as gasoline or electricity from coal-fired power plants — produced by the 111 biggest carbon-oriented companies going as far back as 137 years, because that's as far back as any of the companies' emissions data go and carbon dioxide stays in the air for much longer than that. They used 1,000 different computer simulations to translate those emissions into changes for Earth's global average surface temperature by comparing it to a world without that company's emissions.Using this approach, they determined that pollution from Chevron, for example, has raised the Earth’s temperature by .045 degrees Fahrenheit (.025 degrees Celsius).The researchers also calculated how much each company's pollution contributed to the five hottest days of the year using 80 more computer simulations and then applying a formula that connects extreme heat intensity to changes in economic output. Mankin said that in the past, there was an argument of, “Who's to say that it's my molecule of CO2 that's contributed to these damages versus any other one?” He said his study “really laid clear how the veil of plausible deniability doesn't exist anymore scientifically. We can actually trace harms back to major emitters.”Shell declined to comment. Aramco, Gazprom, Chevron, Exxon Mobil and BP did not respond to requests for comment.“All methods they use are quite robust,” said Imperial College London climate scientist Friederike Otto, who heads World Weather Attribution, a collection of scientists who try rapid attribution studies to see if specific extreme weather events are worsened by climate change and, if so, by how much. She didn't take part in the study. “It would be good in my view if this approach would be taken up more by different groups. As with event attribution, the more groups do it, the better the science gets and the better we know what makes a difference and what does not,” Otto said. So far, no climate liability lawsuit against a major carbon emitter has been successful, but maybe showing “how overwhelmingly strong the scientific evidence” is can change that, she said.In the past, damage caused by individual companies were lost in the noise of data, so it couldn't be calculated, Callahan said. “We have now reached a point in the climate crisis where the total damages are so immense that the contributions of a single company's product can amount to tens of billions of dollars a year,” said Chris Field, a Stanford University climate scientist who didn't take part in the research.This is a good exercise and proof of concept, but there are so many other climate variables that the numbers that Callahan and Mankin came up with are probably a vast underestimate of the damage the companies have really caused, said Michael Mann, a University of Pennsylvania climate scientist who wasn't involved in the study.Follow Seth Borenstein on X at @borenbears.

Vineyards in NY Wine Country Push Sustainability as They Adapt to Climate Change

The Finger Lakes are home to New York’s largest wine-producing region, but vineyards there are struggling with the impacts of climate change

PENN YAN, N.Y. (AP) — A decade ago, Scott Osborn would have eagerly told prospective vineyard owners looking to join the wine industry to “jump into it.”Now, his message is different.“You’re crazy,” said Osborn, who owns Fox Run Vineyards, a sprawling 50-acre (20-hectare) farm on Seneca Lake, the largest of New York’s Finger Lakes.Despite the challenges, however, many winegrowers are embracing sustainable practices, wanting to be part of the solution to global warming while hoping they can adapt to changing times. EDITOR’S NOTE: This story is a collaboration between Rochester Institute of Technology and The Associated Press. The Finger Lakes, which span a large area of western New York, have water that can sparkle and give off a sapphire hue on sunny days. More than 130 wineries dot the shorelines and offer some of America’s most famous white wines. At Fox Run, visitors step inside to sip wines and bring a bottle — or two — home. Many are longtime customers, like Michele Magda and her husband, who have frequently made the trip from Pennsylvania.“This is like a little escape, a little getaway,” she said.Traditionally, the plants’ buds break out in spring, emerging with colorful grapes that range from the cabernet franc’s deep blues to the soft greens of the region’s most popular grape, riesling. However, a warming world is making that happen earlier, adding to uncertainty and potential risks for farmers. If a frost comes after the buds have broken, growers can lose much of the harvest. Year-round rain and warmer night temperatures differentiate the Finger Lakes from its West Coast competitors, said Paul Brock, a viticulture and wine technology professor at Finger Lakes Community College. Learning to adapt to those fluctuations has given local winemakers a competitive advantage, he said. Winegrowers as part of the solution Many winegrowers say they are working to make their operations more sustainable, wanting to help solve climate change caused by the burning of fuels like gasoline, coal and natural gas.Farms can become certified under initiatives such as the New York Sustainable Winegrowing program. Fox Run and more than 50 others are certified, which requires that growers improve practices like bettering soil health and protecting water quality of nearby lakes. Beyond the rustic metal gate featuring the titular foxes, some of Osborn’s sustainability initiatives come into view.Hundreds of solar panels powering 90% of the farm’s electricity are the most obvious feature. Other initiatives are more subtle, like underground webs of fungi used to insulate crops from drought and disease.“We all have to do something,” Osborn said. One winegrower's sustainability push — and struggle to stay in business For Suzanne Hunt and her family’s 7th-generation vineyard, doing something about climate change means devoting much of their efforts to sustainability. Hunt Country Vineyards, along Keuka Lake, took on initiatives like using underground geothermal pipelines for heating and cooling, along with composting. Despite the forward-looking actions, climate change is one of the factors forcing the family to make tough decisions about their future.Devastating frosts in recent years have caused “catastrophic” crop loss. They’ve also had to reconcile with changing consumer attitudes, as U.S. consumption of wine fell over the past few years, according to wine industry advocacy group Wine Institute.By this year’s end, the vineyard will stop producing wine and instead will hold community workshops and sell certain grape varieties.“The farm and the vineyard, you know, it’s part of me,” Hunt said. “I’ll let the people whose dream and life is to make wine do that part, and I’ll happily support them.” Tariffs and US policy changes loom Vinny Aliperti, owner of Billsboro Winery along Seneca Lake, is working to improve the wine industry’s environmental footprint. In the past year, he’s helped establish communal wine bottle dumpsters that divert the glass from entering landfills and reuse it for construction materials.But Aliperti said he’d like to see more nearby wineries and vineyards in sustainability efforts. The wine industry’s longevity depends on it, especially under a presidential administration that doesn’t seem to have sustainability at top of mind, he said. “I think we’re all a bit scared, frankly, a bit, I mean, depressed,” he said. “I don’t see very good things coming out of the next four years in terms of the environment.”Osborn is bracing for sweeping cuts to federal environmental policies that previously made it easier to fund sustainability initiatives. Tax credits for Osborn’s solar panels made up about half of over $400,000 in upfront costs, in addition to some state and federal grants. Osborn wants to increase his solar production, but he said he won’t have enough money without those programs.Fox Run could also lose thousands of dollars from retaliatory tariffs and boycotts of American wine from his Canadian customers. In March, Canada introduced 25% tariffs on $30 billion worth of U.S. goods — including wine.Osborn fears he can’t compete with larger wine-growing states like California, which may flood the American market to make up for lost customers abroad. Smaller vineyards in the Finger Lakes might not survive these economic pressures, he said.Back at Fox Run's barrel room, Aric Bryant, a decade-long patron, says all the challenges make him even more supportive of New York wines. “I have this, like, fierce loyalty,” he said. "I go to restaurants around here and if they don’t have Finger Lakes wines on their menu, I’m like, ‘What are you even doing serving wine?’”The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.
