As Green Bonds Tank, Analysts Fear Greenwashing Is to Blame

Friday, September 20, 2024

When Italian energy giant Enel announced in April that it had failed to meet the carbon emissions reduction goals in a third of its sustainability linked bonds (SLB), it exposed significant deficiencies in a once-coveted form of loan aimed at reining in climate-altering carbon emissions.  It also raised concerns about whether companies such as Enel and the banks that underwrite the sustainability linked bonds were truly interested in combating climate change or in merely making misleading claims of being environmentally friendly, a practice known as greenwashing. Enel was the first and largest corporate issuer of sustainability linked bonds, which are a form of green bonds that raise capital for general corporate purposes rather than for specific renewable energy projects. With SLBs, a discounted rate of about 10%-15% is tied to reaching certain sustainability indicators, such as decarbonization metrics, renewable energy consumption or generation and the volume of recycled materials.  At their debut in 2019, sustainability linked bonds were welcomed as a way for industrial companies and banks to show that they were taking steps to achieving net-zero emissions by 2050. With the bonds, climate change could even be addressed by heavy polluters, such as automakers or steel manufacturers, which otherwise might not have projects eligible for traditional green bonds.  Initially, the sustainability linked bond market grew rapidly, soaring to over $100 billion in global volume in 2021. But since then the market has hit a wall. In the first quarter of 2024, the global SLB volume peaked at $3.1 billion, down 37% from the same period the prior year. Experts attribute the steep drop to growing investor concerns that the bonds are failing to induce any real reductions in carbon emissions.  Enel missed its target for direct emissions by about 8%, a deficiency that triggered an automatic 0.25% increase in the interest rate on the affected bonds. The financial hit was relatively minor, amounting to around $100 million over the remaining life of the bonds for a company whose annual revenue was $103 billion last year.  Enel attributed the shortfall to higher-than-expected coal-based electricity generation, in part mandated by the Italian government in the wake of the Russian invasion of Ukraine and the subsequent disruption in European gas supplies. But that explanation did not temper reactions in the sustainability linked bond market. Enel had embraced SLBs as part of a well-publicized strategy to develop a business model in line with the Paris Agreement to limit the average global temperature increase to 1.5 degrees Celsius (2.7 F).  In the wake of Enel’s failure to meet its emission goals, concerns grew that if the sustainability linked bonds were insufficient to ensure that Enel’s highly motivated sustainability program reached its goals, what were the odds the bonds would have a consequential impact on the decarbonization efforts of a less committed bond issuer? Moreover, investors and underwriters supporting the sustainability linked bond market — a group that in Enel’s case included major financial players such as BNP Paribas, Crédit Agricole, Citigroup, Commerzbank, Goldman Sachs, JP Morgan and Societe Generale — often did so to claim these instruments as part of their “green” portfolios.  “SLBs can be a valuable climate change tool, a difference maker, but two things are necessary: The target goals must be ambitious, offering a credible decarbonization pathway, and the consequences of failing to meet those goals must be a deterrent to falling short,” said Kevin Leung, a sustainable finance analyst at the Institute for Energy Economics and Financial Analysis.  Despite the high hopes for sustainability linked bonds, about 86% of the 800 bonds that so far have been issued lack adequate greenhouse gas reduction targets to achieve global climate change goals, according to Climate Bonds Initiative, which analyzes the green bond marketplace.  In general, the bonds’ sustainability indicators are either too ambiguous or too shortsighted to align with science-based carbon abatement solutions or their monitoring protocols are not sufficiently robust or transparent — shortcomings often ignored by investors. As a result, a Climate Bonds analysis of more than 150 bonds from top issuers through November 2023 found that in about half of the cases, companies are not on track to meet their climate goals or have failed to provide evidence of their progress. Only 25% appear to be on target to reach their goals.  French oil and gas major TotalEnergies provides an apt illustration of the gap between the purpose of sustainability linked bonds and their results. In 2021, Total announced that all its future debt would be issued as SLBs, linked to its climate targets. To kick off this strategy, in January 2021 Total issued about $3.2 billion in SLB-style bonds with an average interest rate of 1.875%, in part to further its development of nonfossil fuel energy sources, the company said. Total reveled in the discounted cost of capital, describing it as “comparable to that of pure players in renewables.”  To get this advantageous rate, Total did the minimum, offering only generic claims about its sustainability initiatives, including the promise of a mere 20% reduction in the carbon intensity of its oil products by 2030, when most companies would aim for a more robust reduction. Total also stated, without any guarantees, that a transition to renewable energy was its unwavering priority. No scheduled metrics for monitoring the organization’s performance was included in the loan.  By contrast, a more robust goal was laid down by Kinetik, a U.S.-based natural gas company that issued nearly $4 billion in sustainability-linked bonds in 2022 and 2023. The company has targeted a 35% reduction in greenhouse-gas emissions from its operations by 2030.  Even Total’s vague assurances appear to run counter to Total’s actual plans. In 2030, two-thirds of Total’s capital expenditures will still be earmarked for oil and gas with nearly half for new fields, according to an analysis by Oil Change International. By that time, oil and gas will account for 80% of Total’s energy mix, compared with 95% in 2021, which actually means that Total’s fossil fuel production will increase by about 3%, a separate report by Reclaim Finance found.  But if Total has become a symbol of how sustainability linked bonds can be misused and rendered toothless, the company’s lenders have not been put off. During shareholder votes about Total’s decarbonization policies, investment managers Amundi and AXA said that by merely vowing to focus on energy transition,Total has proved its intention to adopt more ambitious climate targets over time. And BlackRock said it was satisfied that Total’s “stated carbon neutrality strategy meets our expectations of a company committed to the energy transition.”  In fact, global asset manager BlackRock believed that Total’s enthusiastic embrace of sustainability linked bonds was evidence enough that it would ultimately achieve net zero goals. That justification for supporting Total’s debt has not aged well: In April, three years after announcing its SLB strategy and issuing debt at discounted interest rates, Total said it was abandoning the approach. According to one analyst who follows SLBs closely but asked to remain anonymous because of his relationship with other companies he does business with, Total’s investors told him they had become less willing to give the company discounted loans for empty promises and little headway towards addressing climate change.  Most sustainability linked bonds are more explicit about targeted outcomes than Total’s bonds. But that only highlights a fundamental flaw in this type of debt. Generally, the issuers meet or come close to their goals only because their metrics are not particularly difficult to achieve — in some cases, reflecting results reached prior to the bond issuance — or are not connected to the way a particular company can impact climate change.  Compounding matters, some of the most crucial measurements of decarbonization are often absent from sustainability linked bond goals. Scope 3 emissions, those that occur outside an organization’s direct control and usually account for the largest source of a company’s carbon output, are not covered in 70% of sustainability linked bonds underwritten by top issuers. Estimating Scope 3 emissions is difficult, but there are ways to cover these greenhouse gases, such as metrics that measure the share of renewable energy in a supply chain, or the percentage of a company’s products recycled by consumers.  On the demand side of sustainability linked bonds, the pricing and penalties mechanisms are also contributing to the deficient key performance indicators (KPI), the metrics used to measure environmental performance.  “The major problem here is that the link between KPIs and the interest rate paid in the loan is weak,” said Joachim Klement, a London-based investment strategist. He and others believe that the discounts of a few basis points that issuers receive are not large enough to entice companies to undertake an expensive and potentially disruptive decarbonization program. Moreover, the penalties for not meeting climate change goals — generally a 0.25% increase in interest rates — are too weak to deter missed targets, especially for big companies like Enel. Since sustainability goals take time to reach, companies can often enjoy interest discounts for several years before paying a step-up for a short period until the bond matures.  Unless sustainability linked bonds (and other green bonds) begin to play a perceptible role in addressing climate change, net zero and global temperature goals are likely impractical and out of reach. And to a large degree, that puts the onus on financial backers and underwriters to set the SLB market straight, demanding meaningful and carefully defined environmental improvements in return for real and advantageous interest rate discounts — and to require strict and scientific monitoring protocols to certify the key performance indicators are met.  Additionally, if SLB shortcomings are not addressed, regulators may ultimately determine that these bonds should not even be categorized as green investments. That possibility has already made sustainability linked bonds less attractive to some investors, say experts.  Still, many climate change investment supporters are hopeful that SLBs can play a constructive role in corporate decarbonization and provide a venue for credible green investments. It is somewhat fitting, perhaps, that it took bond defaults by Enel, a true believer in using lending as a cudgel against climate change, to inspire a reckoning about sustainability linked bonds.  Copyright 2024 Capital & Main

Under a Coalition government, the fate of Australia’s central climate policy hangs in the balance

Both major parties agree Australia must reach net-zero emissions. That’s why winding back the safeguard mechanism would be reckless policy.

RobynCharnley/ShutterstockThe future of Australia’s key climate policy is uncertain after Opposition Leader Peter Dutton said a Coalition government would review the measure, known as the “safeguard mechanism”, which is designed to limit emissions from Australia’s largest industrial polluters. According to the Australian Financial Review, if the Coalition wins office it will consider relaxing the policy, as part of its plan to increase domestic gas supplies. Evidence suggests weakening the mechanism would be a mistake. In fact, it could be argued the policy does not go far enough to force polluting companies to curb their emissions. Both major parties now accept Australia must reach net-zero emissions by 2050. This bipartisan agreement should make one thing clear: winding back the safeguard mechanism would be reckless policy. What’s the safeguard mechanism again? The safeguard mechanism began under the Coalition government in 2016. It now applies to 219 large polluting facilities that emit more than 100,000 tonnes of greenhouse gases a year. These facilities are in sectors such as electricity, mining, gas, manufacturing, waste and transport. Together, they produce just under one-third of Australia’s emissions. Under the policy’s original design, companies were purportedly required to keep their emissions below a certain cap, and buy carbon credits to offset any emissions over the cap. However, loopholes meant the cap was weakly enforced. This meant greenhouse gas pollution from the facilities actually increased – rising from 131.3 million tonnes to 138.7 million tonnes in the first six years of the policy. Labor strengthened the safeguard mechanism after it won office, by setting a hard cap for industrial emissions. The Coalition voted against the reforms. Dutton has since labelled the safeguard mechanism a “carbon tax” – a claim that has been debunked. Some members of the Coalition reportedly believe the policy makes manufacturers globally uncompetitive. Now, according to media reports, a Coalition government would review the safeguard mechanism with a view to weakening it, in a bid to bolster business and increase gas supply. Why the safeguard mechanism should be left alone Weakening the safeguard mechanism would lead to several problems. First, it would mean large facilities, including new coal and gas projects, would be permitted to operate without meaningful limits on their pollution. This threatens Australia’s international climate obligations. Second, if polluters were no longer required to buy carbon offsets, this would disrupt Australia’s carbon market. As the Clean Energy Regulator notes, the safeguard mechanism is the “dominant source” of demand for Australian carbon credits. In the first quarter of 2024, about 1.2 million carbon-credit units were purchased by parties wanting to offset their emissions. The vast majority were purchased by companies meeting compliance obligations under the safeguard mechanism or similar state rules. If companies are no longer required to buy offsets, or they buy fewer offsets, this would hurt those who sell carbon credits. Carbon credits are earned by organisations and individuals who abate carbon – through measures such as tree planting or retaining vegetation. The activities are often carried out by farmers and other landholders, including Indigenous organisations. Indigenous-led carbon projects have delivered jobs, cultural renewal and environmental benefits. The safeguard mechanism, together with the government pledge to reach net-zero emissions by 2050, also provides certainty for the operators of polluting facilities. Many in the business sector have called for the policy to remain unchanged. And finally, winding back the safeguard mechanism would send a troubling signal to the world: that Australia is stepping back from climate action. Now is not the time to abdicate our responsibilities on climate change. Atmospheric carbon dioxide levels have risen dramatically since 1960. This increase is driving global warming and climate change, leading to extreme weather events which will only worsen. A hard-won policy The safeguard mechanism has not had time to deliver meaningful outcomes. And it is far from perfect – but it is hard-won, and Australia needs it. The 2023 reforms to the mechanism were designed to support trade-exposed industries, while encouraging companies to invest in emissions reduction. Undoing this mechanism would risk our climate goals. It would leave the government limited means to curb pollution from Australia’s largest emitters, and muddy the roadmap to net-zero. It would also create uncertainty for all carbon market participants, including the polluting facilities themselves.

Why 50-Degree-F Days Feel Warmer in Spring Than in Fall

There are real, physiological reasons why the same temperature feels different in April and October

In the first few weeks of spring, a 50-degree-Fahrenheit (10-degree-Celsius) day might call for a light jacket or no jacket—or even short sleeves, depending on the person. But in the fall, the same weather might have you reaching for a parka.It’s not just in your head. The relative warmth of spring is physiological as well as psychological; after a long, biting winter, your body has changed in ways that can make 50 degrees F seem downright balmy.“I fully experience this on a regular basis with my work,” says Cara Ocobock, an anthropologist at the University of Notre Dame, who studies how the human body adapts to cold. Her work often takes her to Finland, where she studies populations of reindeer herders who spend lots of time in extreme cold.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.“The human body is very good at acclimatizing to different environmental situations that are not permanent—and the changes that your body experiences during this time also aren’t permanent,” she says. Some of these changes involve a heat-generating organ that was only recently discovered in adults.Scientific American spoke with Ocobock to learn more about the changes our bodies undergo during winter—including to that strange, newfound organ—and how these changes affect us when the winter chill finally gives way to the warmth of spring.Have you personally experienced this “50 degrees feels warm” phenomenon?Yes, I have a story from my last trip to Finland. I was 300 kilometers [185 miles] north of the Arctic Circle during what should have been the coldest time of the year. There were maybe four or five days where it didn’t get above –20 degrees Fahrenheit [–29 degrees Celsius]. But then five days later, it was in the positive 40s Fahrenheit [or five to 10 degrees C], which should not exist that far north that time of year. After those days of extreme cold, I started sweating [when it went] above freezing. I wouldn’t even wear a coat. My body just kind of reversed course—like, “We need to cool you down; this is not what we have been used to.”How quickly do these physiological changes happen when someone is exposed to more extreme temperatures?There’s always going to be individual and populational variation, but we see the changes start happening pretty quickly. It can start within 24 hours, but they don’t fully set in for about seven to 10 days. You will maintain those changes until you go and switch environments again, and then you’ll lose your acclimatization. This can be to heat, cold, humidity, dryness or high altitude as well. For example, when I [returned to sea level from] field work in the Rocky Mountains, I was able to do two full lengths of an Olympic swimming pool without breathing. Within two weeks, that was gone.So how do our bodies change when we are exposed to cold weather?There’s a constant balancing of several different systems going on here. One of the quick changes is an increase in your resting metabolic rate—the baseline number of calories your body burns in order to survive. Your body is kind of increasing its own thermostat to produce more heat because you are losing more heat to the environment.We also see changes in the way your blood vessels [tighten or expand] to respond to the cold. In the cold, [vessels constrict to] reduce how much blood is flowing through and the heat that can potentially be lost to the environment. And when you’re cold, blood will be shunted more to the deep blood vessels that are further away from the surface, whereas in a hot climate, the opposite happens.We also see and increase in brown adipose tissue activity—this is an active area of research. “Brown fat,” as we call it colloquially, is a type of fat that burns only to keep you warm during acute cold exposure. In adult humans, it’s located [just above your clavicles], as well as along your major deep blood vessels. This organ, and we do consider it kind of its own organ, uses energy to produce heat—not energy to [activate your muscles] to go run a mile or anything like that. We used to think that human adults never have brown fat. We knew that babies have it [for the first few months of life], but we thought that once they burned through it, that was it. But we are now seeing brown adipose tissue everywhere we look in adult human populations.How is brown fat different from regular fat?Brown adipose tissue is very, very rich in mitochondria. Instead of being the powerhouse of the cell, those mitochondria are the furnace. It basically short-circuits the typical process so that this tissue produces heat rather than energy.In adults, to date, we have seen brown fat in populations in Russia and Finland—cold climates, which makes sense. We’ve seen it in Albany, N.Y.—temperate climate but cold winters. And we’ve also seen it in Samoa—a tropical island climate. So we’re beginning to think that brown adipose tissue might be a very deeply ancient tissue and that it could have been around in our evolutionary history for a very long time.How does brown fat activity change during cold seasons?One study on seasonal changes in brown adipose tissue [was] conducted by my former graduate student, Alexandra Niclou. She looked at seasonal variation in a brown adipose tissue among folks in Albany. She found that people were able to maintain higher body temperatures from brown fat in the winter but at a reduced caloric cost. And so it seemed the brown fat actually got more efficient the more it was being used to maintain body temperature in the winter. So there does seem to be a physiological difference in how brown fat is responding between the seasons. I’m going back to Finland this spring [to measure this further] among reindeer herders and indoor workers.Given all of those factors, what do you think is happening to our bodies on that first “warm” spring day?In the winter, you’re going to have an increase in resting metabolism. You might see an increase in your brown adipose tissue activity in order to keep you warm. Then all of a sudden it’s 50 degrees Fahrenheit outside, but your resting metabolic rate is still going to be higher, [and your brown fat might be more active], which means your body is producing more heat than it typically would have been. That’s probably why you feel like it’s way warmer out and start sweating. That acclimatization process is going to take a week or more to get you used to this new, warmer temperature setting.There’s also a developmental aspect of this—where you grew up likely has a massive, massive impact on how your body responds to different extremes and changes in seasonal temperatures. I’m a college professor [in Indiana], and walking around campus this time of year, you can tell the kids from the East Coast and the Midwest versus those from the South and the West Coast [by who is wearing] short T-shirts and sandals when it’s, like, 50 degrees and [who is] still in puff jackets. It always cracks me up. And we might actually see happening with brown adipose tissue as well—that the more you are exposed to cold during critical developmental periods as a child, the more active and responsive your brown adipose tissue may be as an adult.Do these seasonal changes still impact you if you spend most of the winter indoors?They are definitely still impacting you. It might not be as much, obviously, and this is part of what we’re doing with our work in Finland with reindeer herders, who spend more time outside in the extreme cold, and indoor office workers in the same region. But because you still go outside, you still experience acute cold, [even if it’s not] for hours and hours on end.Why is it important to understand how our bodies acclimatize to extreme temperatures?Understanding how bodies rapidly respond [to changes in temperature] is going to be even more important in the face of climate change, when we have highly and dramatically variable environments —where you get ice storms in Texas, for example. [Helping people acclimatize via what we know about] biology, behavior and technology is going to be critical, I think, because no matter what, our bodies are going to be physiologically limited in coping with both extreme cold and extreme heat. Our bodies are not limitless, so we have [to adjust our] behavior and turn to technology to make up for what our bodies can’t do.

The Psychological Effects of Climate Change: The Scientific Explanations — and Solutions That Can Empower Your Mind

Our minds can flip the script on climate change. Here are ways to reframe our perceptions and make us more resilient and empowered. The post The Psychological Effects of Climate Change: The Scientific Explanations — and Solutions That Can Empower Your Mind appeared first on The Revelator.

Are environmental and climate change problems overwhelming you? As psychologists my colleagues and I increasingly see the psychological and physiological effects of climate stress on our clients. These effects — including “fear of the unknown,” instability, catastrophizing, financial insecurity, and biophysiological alterations due to unseasonal weather events — create an ominous feeling of chaos, adversely affecting people’s emotional and mental equilibrium and making it hard to focus on clear actions, solutions, and effective pathways to fighting back climate confusion. This can leave us feeling deeply uneasy about the future. How can we cope with these feelings of overwhelming apprehension or hopelessness? As individuals we can’t take on the world — that’s an impossible task. So do we just turn away and give up? Of course not. Instead let’s look at more productive approaches to applying the brakes when anxiety, nihilism, and emotional shutdown leave us stuck in place. There’s a new and growing field in psychology focused on addressing the increasing burdens on our psyches due to climate chaos. Climate psychology addresses the emotional, mental, and sociological processes that contribute to the climate crisis, and human responses and adaptations to that can make positive, proactive, and productive solutions to climate-change events. As I’ve seen with my clients, friends, family, and community, the effects of climate change on mental and emotional wellbeing require a fresh approach to this lived experience challenge. For many people the first step to addressing this psychological crisis starts in our own minds. Psychologically this is known as “taking back the power”: Choose to do something — something that will empower you, energize you, and heal the trauma of climate insecurity, ignorance, and willful destruction by the rich and powerful. Before we do that, though, it helps to understand the psychological and physiological damage we’re trying to heal. “Where Did the World I Used to Know Go?” The word “solastalgia” describes the emotion of longing for a natural world that no longer exists. You’ve probably experienced this: The ongoing disruption of seasonal weather’s traditional timing makes us feel deeply disoriented, moody, depressed, confused, irritable, and uneasy on a subconscious level as our bodies’ biological, mind-affecting chemicals become unbalanced — much like what’s happening to our planet. There are biochemical reasons for these emotions caused by climate disruption. Climate trauma causes remarkable physiological — and therefore psychological — alterations to human biochemistry that significantly alter brain chemistry, leading to dysregulation of neurotransmitters and hormones like cortisol, norepinephrine, and dopamine. This adversely affects normal stress response, memory, and emotional regulation. Physiologically, increased heat and climate instability can even accelerate the aging process, new research suggests. Examples of events that disorient and alter our minds include: Plants bloom too early for the wildlife that depend on them, pushing them out of synch with the natural system. Salt and freshwater wildlife migrate with warmer temperatures, disrupting our food systems. Wildlife and plants become infected with disease or poisoned due to algae blooms or poisonous flood runoff. Drought causes water insecurity, increases costs, and threatens livelihoods. The loss of slow “transitional seasons” like spring and autumn causes deep temperature swings — and mood swings. Warmer climates mean invasive species, whether planted by humans or caused by “species creep” out of inhospitable climates. Diseases kill wildlife who historically have kept disease-carrying pest populations down. These disruptions alter our behavior and affect some of our most significant life choices. Climate Change Affects Life’s Biggest Decisions People are now questioning important life decisions under an uncertain climate context. Should we have children? Should we buy a home? Where should we live? Can we afford children and a home mortgage? Will there be food and clean water? How secure is my job? This is the psychological trauma and uncertainty of displacement, which leaves us feeling trapped, without agency or control. We can’t look into a crystal ball and see the future, but climate anxiety and resource insecurity create a very difficult, confusing decision-making process when planning family, home, job, and community. The increasingly likely threats of displacement — loss of life and health, region, or country — are highly stressful and traumatic because they’re unpredictable. Globally we see the increasing geographical relocation of individuals, cultures, and communities. Leaving behind generations of the family sense of “home” is highly traumatic as entire cultures must relocate due to resource insecurities caused by drought, floods, invasive species, or the extinction of native species. These insecurities cause extreme and enduring stress. A few examples include the rising cost or unavailability of insurance for disasters, community dissolution, loss of a “home” or place, and friends and family scattering to new geographic locations because of better opportunities there. Globally these events affect local, federal, and international government and political decision-making. Huge migrations of wildlife and humans to other geographical locations upset existing populations, which causes perceived cultural threats, so emigrants are demonized, segregated, and violence erupts, destabilizing societies and governments. All of this creates a universal sense of helplessness: “There’s nothing I can do, so why bother?” Take Back Your Power: Try This Psychology 101 Exercise Exercise 1. Spend an hour enviro-dooming online. It’s easy. Go for it with gusto: Furiously repost the bad things, “like,” and share — send the doom to all your groups and friends. The algorithms and AI will direct you to every negative environmental disaster online, because the scientists hired by Big Tech know what excites your brain chemicals and tickles your brain’s pleasure centers. It’s based on addiction science: Create exciting content, keep supplying more stimulation and agitation. Big Tech is a drug dealer for negative, aggressive, pleasurable chemicals. You’ll always get a fix, because Big Tech algorithms and AI now know your mind — and offers your brain maladaptive chemical and behavioral solutions. Now stop and check yourself. Scan your mind and body. How do you feel? Exercise 2: Turn off all your electronics. Get up and go for a walk, stroll into town and see what’s happening. Art shows? Community events? Farmers markets? What’s new at the library and community center? Is there a park to kick back and enjoy nature? Smile and be nice to strangers and shop clerks, open a door for someone, help someone with directions, or help an elderly or disabled person reach that can of corn on the top shelf. Research shows that when we smile and act nice to strangers, we get a burst of serotonin and other happiness chemicals in our brains. And the people we help do too. It’s contagious. Now how do you feel? We can all take advantage of that reset. Whether we’re talking about climate change, civil rights, politics, or anything else, you control the mediums you expose yourself to. Use your critical thinking, set limits and boundaries, resist the manipulation of media. It takes some practice to resist bad habits. But we can do it. Let’s reframe your relationship with the world in its current health. Start with your mindset, then, using what you discovered above, branch out into your community. Get involved with others around you and you’ll soon find yourself making small local changes, then bigger ones as your positive engagement ripples outward to others. See how those positive brain chemicals like dopamine, serotonin, oxytocin, and endorphins — which play crucial roles in regulating mood, promoting well-being, and fostering feelings of pleasure and satisfaction — are radiating out to others, and the world. Be kind to yourself. It all starts with you.

Scientists Shielding Farming From Climate Change Need More Public Funding. but They're Getting Less

Public funding for agricultural research in the U.S. has been declining for the last two decades, a process Trump has rapidly accelerated by freezing or pausing support for a variety of research programs financed by the USDA, EPA and other organizations

Erin McGuire spent years cultivating fruits and vegetables like onions, peppers and tomatoes as a scientist and later director of a lab at the University of California-Davis. She collaborated with hundreds of people to breed drought-resistant varieties, develop new ways to cool fresh produce and find ways to make more money for small farmers at home and overseas.Then the funding stopped. Her lab, and by extension many of its overseas partners, were backed financially by the United States Agency for International Development, which Trump's administration has been dismantling for the past several weeks. Just before it was time to collect data that had been two years in the making, her team received a stop work order. She had to lay off her whole team. Soon she was laid off, too.“It’s really just been devastating,” she said. “I don’t know how you come back from this.”The U.S. needs more publicly funded research and development on agriculture to offset the effects of climate change, according to a paper out in Proceedings of the National Academy of Sciences this month. But instead the U.S. has been investing less. United States Department of Agriculture data shows that as of 2019, the U.S. spent about a third less on agricultural research than its peak in 2002, a difference of about $2 billion. The recent pauses and freezes to funding for research on climate change and international development are only adding to the drop. It’s a serious issue for farmers who depend on new innovations to keep their businesses afloat, the next generation of scientists and eventually for consumers who buy food.“This is terrible news for the U.S. agricultural sector,” said Cornell associate professor Ariel Ortiz-Bobea, the lead author of the paper. Trump administration hastens funding cuts As the Trump administration pauses and shutters research programs funded by the Environmental Protection Agency, USDA and other agencies, Ortiz-Bobea and other experts have seen field trials stopped, postdoctoral positions eliminated and a looming gap forming between the reality of climate change and the tools farmers have to deal with it.The EPA declined to comment, and the USDA and USAID did not respond to Associated Press queries.Ortiz-Bobea and his team quantified overall U.S. agricultural productivity, estimated how much it would be slowed by climate change in coming years and calculated how much money would need to be invested in research and development to counteract that slowdown.Think of it like riding a bike into a headwind, Ortiz-Bobea said. To maintain the same speed, you have to pedal harder; in this case, R&D can be that extra push.Some countries are heading that direction. China spends almost twice as much as the U.S. on agricultural research, and has increased its research investments by five times since 2000, wrote Omanjana Goswami, a scientist with the Food and Environment team at the Union of Concerned Scientists, in an email.Spending cutbacks have also shuttered agricultural research across almost all of the Feed the Future Innovation Labs, of which McGuire's was one. Those 17 labs across 13 universities focused on food security, technical agriculture research, policy and various aspects of climate change. The stop-work orders at those labs not only disappointed researchers, but made useless much of their work.“There are many, many millions of dollars of expenditure that will generate nothing now because the work couldn’t be finished,” said David Tschirley, a professor who had been directing another one of those programs, the Innovation Lab for Food Security Policy Research, Capacity and Influence at Michigan State University, since 2019. Finding new funding for agricultural research Some researchers hope that other sources of funding can fill the gaps: “That’s where private sector could really step up,” said Swati Hegde, a scientist in the Food, Land, and Water Program at the World Resources Institute.From an agricultural point of view, climate change is “really scary,” with larger and larger regions exposed to temperatures above healthy growing conditions for many crops, said Bill Anderson, CEO of Bayer, a multinational biotechnology and pharmaceutical company that invested nearly $3 billion in agricultural research and development last year. But private companies have their own constraints on R&D investment, and he said Bayer can't invest as much as it would like in that area. “I don’t think that private industry can replicate" how federal funding typically supports early stage, speculative science, he said, “because the economics don't really work.” He added that industry tends to be better suited to back ideas that have already been validated. Goswami, of the Union of Concerned Scientists, also expressed concerns that private research funding isn't as trackable and transparent as public funding. And others said even sizeable investments from companies don't give anywhere near enough money to match government funding. Researchers, farmers and consumers feel the fallout The full impact may not be apparent for many years, and the damage won't easily be repaired. Experts think it will be a blow in other countries where climate change is already decimating yields, driving hunger and conflict. “I really worry that if we don’t really look at the global food situation, we will have a disaster,” said David Zilberman, a professor at UC Berkeley who won a Wolf Prize in 2019 for his work on agriculture.But even domestically, experts say one thing is almost certain: this will mean even higher prices at the grocery store now and in the future.“More people on the Earth, you need more productivity to prevent food prices going crazy,” said Tom Hertel, a professor of agricultural economics at Purdue University. Even if nothing changes right away, he thinks “10 years from now, 20 years from now, our yield growth will surely be stunted” by cuts to research on agricultural productivity.Many scientists said the wound isn’t just professional but personal. “People are very demoralized,” especially younger researchers who don’t have tenure and want to work on international food research, said Zilberman.Now those dreams are on hold for many.
