Replicating Nature 

As the effects of anthropogenic greenhouse gas emissions become increasingly well understood, researchers like Dr. Peidong Yang at UC Berkeley are developing technologies that address human-caused climate change with a nature-based approach. Dr. Yang’s artificial leaves capture sunlight and carbon dioxide and produce C2, a key precursory ingredient in the production of many everyday items. 

 

Diving Deeper 

Though synthetic fuels have been manufactured for over a century - by combining carbon monoxide and hydrogen - these new structures may be able to generate fuel in a more sustainable way by harnessing solar energy. The artificial leaves produce ethylene and ethane, showing that artificial leaves can create hydrocarbons; previously, similar structures have only been able to separate water into oxygen and hydrogen. 

A few innovations make this process possible. One is the catalyst, a microscopic copper structure, flower-like in appearance. According to another scientist working on the project, Virgil Andrei, the copper nanoflowers can be adjusted, based on the desired outcome: “Depending on the nanostructure of the copper catalyst you can get wildly different products.” Another innovation occurs on the side of the device opposite the nanoflowers - 

 

Benefits 

The benefits for climate change are two fold. First, these artificial leaves can remove CO2 that’s already been released into the atmosphere by mimicking what natural leaves do through photosynthesis. These artificial leaves uptake CO2 from the air, and use it to make all sorts of different chemicals that can be utilized to create fuel. 

The second major benefit is this technology is an opportunity to revolutionize the current chemical industry. Right now, the chemical industry is powered by fossil fuels converted into the liquid fuel that powers our society. Instead, this artificial photosynthesis allows scientists to create those same very useful chemicals from the CO2 being uptaken by the artificial leaves without any added emissions in the process. Though the carbon will be reemitted once this fuel is used, it works out to be a net carbon-neutral system because the cycle continues—the artificial leaves will reuptake this CO2 as well. So, this net carbon-neutral system is drastically better than the current fossil fuel based system driving our climate crisis. 

 

Issues of Scale

Though this artificial leaf technology is promising for a number of future applications, it’s not ready to be scaled yet. Though the trial system worked, it’s just one step towards developing a commercially viable product. Another scientist, Yanwei Lum, emphasizes that, “The performance is still not sufficient for practical applications.” Once the leaves’ durability and efficiency is improved, they will be adoptable for fuel production. Andrei is optimistic that this step forward could come in the next five to ten years. 

 

Yang’s take on the future of Artificial Leaves 

Currently, the costs and energy needed for the technology are relatively high just because of how new it is. But Yang is confident that they will be able to bring the costs done, as well as the energy needed for the actual chemistry to happen. He also notes that for this to actually revolutionize our fuel production, this technology needs to be implemented at a massive scale. He hopes to see policies mandating new carbon capture technology in the conversion industry down the road.

Impacts of Air Transportation on Climate Change

Air transportation is a major contributor to the fossil fuel economy: studies have shown that aviation is responsible for 3.5 percent of all drivers of climate change from human activities. Planes use immense amounts of kerosene—a flammable liquid used as fuel—in order to travel. When kerosene burns, it releases greenhouse gases like carbon dioxide and black carbon. Also, planes create contrails: “line-shaped clouds produced by an airplane’s hot engine exhaust interacting with cold humid air several miles above the Earth’s surface.” These are the lines of white you see behind a plane as it flies overhead: small water particles from the plane’s engine exhaust that have frozen to become visible ice crystals. Because these are essentially clouds, when they persist past a short period of time, they have the potential to trap heat in the atmosphere, leading to a warming effect with many negative climate change consequences.

Advanced Air Mobility as a Climate Solution

In order to combat these negative effects of air travel—and to keep up with increasing demand for shorter distance air travel—researchers have begun looking toward opportunities for low emission options that can be more widely applied. This concept has been coined Advanced Air Mobility (AAM), and seeks to develop transportation technologies which are: “highly automated, electrically powered, and have vertical take-off and landing capability.” One main goal of the project is to develop Urban Air Mobility (UAM) in order to connect underserved communities within cities and rural regions.

Ideally, Advanced Air Mobility will be an environmental improvement because it will use cleaner forms of energy to fuel the transportation, from electricity to hydrogen. According to Adam Cohen of UC Berkeley’s Transportation Sustainability Research Center, there are several different potential uses for the cleaner energy technology, including air taxi services, small package delivery, emergency services, or aeromedical use cases. Airports in particular are confronting a lot of demands for power—both in terms of aviation and ground vehicles—which electric fueled AAM may be able to help fulfill. In terms of hydrogen power, Cohen says manufacturers are testing and have prototypes for a hydrogen aircraft in the hopes that hydrogen will be an entry point for more sustainable flight in the future.

Challenges of Implementation

AAM is still in its early stages of development, and has yet to be implemented in a real way. In order for this to occur, its innovators need to place safety and integration at the forefront, ensuring passenger and cargo safety, as well as minimal disruption to current air traffic pathways. Further, it will be necessary to ensure some level of equitable access in terms of both convenience and cost across groups of people. Ultimately, AAM hopes to be a step in the direction toward clean energy in the aviation sector, encouraging policies and technologies in line with sustainable goals.

Caring for God’s Creation: How Evangelical Christians Are Embracing Climate Action
Across the United States, evangelical Christians are increasingly forging a connection between faith and climate action by redefining environmental work as a sacred duty to care for God’s creation. By understanding sustainability through the lens of biblically mandated stewardship, more and more Christians are discovering renewed hope and purpose in addressing climate change.
What Is Creation Care?
To many evangelical environmentalists, caring for the Earth is not a political act. Rather, it is a spiritual duty. They believe that how we treat the planet should reflect how God treats us: with compassion, responsibility, and reverence. That means resisting the exploitation of natural resources and instead treating the Earth as a divine gift entrusted to humanity.
 
Historically, however, environmentalism and climate science have been viewed as controversial in conservative Christian circles, seen as secular or partisan issues. But that perception is beginning to shift, thanks in part to young leaders and faith-based environmental advocates who are reframing climate action as a moral and theological imperative.
Faith in Action
One of those young leaders is Becca Boyd, a student at Indiana Wesleyan University studying Environmental Science. Raised in a Christian home, Becca often felt her environmental concerns were dismissed and even challenged. Feeling unhead, she began to experience a crisis of faith, questioning both her faith and her place in the church.
 
Everything changed when she was introduced to the concept of creation care in college by her professors. For the first time, she saw how her love for the environment and desire to protect it could be an act of faith rather than in conflict with it.
A Theology of Hope
Like many young people in the climate action space, Becca has felt overwhelmed by the constant sense of “doom and gloom.” The narrative that it’s too late to fix the damage can leave people in despair and feeling helpless. But creation care offers her a more hopeful, spiritually grounded mindset. Rather than dwelling on what’s broken, Becca focuses her energy on healing what’s still possible.
 
For Becca, environmental stewardship is now a form of worship: small acts like conserving energy, recycling, or planting a pollinator garden at her school are ways of honoring God.  And by inviting others to do the same, she’s helping grow a climate movement rooted not in fear but in faith and hope for the future.
Choosing Words That Open Doors
Through her advocacy, Becca has learned that the language you use to talk about climate issues matters, especially in Christian spaces. The word “climate” itself can be politically charged and can trigger defensiveness, while terms like “creation care” and “eco-theology” feel more rooted in faith and shared values.
 
She is also intentional about her tone, making a point to avoid “you” statements. Rather than telling people what they should do, Becca shares what she does and why. This approach opens the door to conversation rather than closing it. According to Becca, it’s about meeting people where they are and establishing a common ground — inviting them in, not calling them out. 
The Challenges Ahead
Creation care is still a growing movement, and while it’s gained traction in places like Indiana, there’s still a long way to go. Climate science skepticism and misinformation continue to circulate in many conservative communities. But Becca and other young Christians are starting vital conversations in churches and on campuses, emphasizing climate change as a humanitarian issue: one that affects food security, public health, and the lives of future generations. 
 
She also shares resources like Cowboy & Preacher, a documentary tracing the history of Christian environmentalism, to show that this movement isn’t new, and that faith and climate action have long been intertwined. 
About Our Guest
Becca Boyd is a rising senior at Indiana Wesleyan University studying Environmental Science. She is a Climate Advocate for Young Evangelicals for Climate Action (YECA) and previously served as a College Fellow. On campus, she launched a student sustainability club and helped lead campus-wide conversations about the intersection of faith and environmental responsibility. She was recently featured in The New York Times for her work advancing Indiana’s growing creation care movement.

India's Battle Against Air Pollution
Historically, India has faced challenges with persistent air pollution as a result of industrial development. One key approach to combat this has been to reduce greenhouse gas emissions. For example, Indian policymakers have been pushing for the commercialization of electric vehicles which has unlocked various incentives for companies like Vision Mechatronics to develop electric vehicles run by lithium-ion batteries. 
How Lithium-Ion Batteries Power EVs
India “seeks to attain a 30% share of electric vehicles, in the total vehicles sold, by 2030” and accelerating the market for it by “moving from incentives to mandates” like a Zero Emission Vehicle policy (NITI Aayog). Taking advantage of this political support, Vision Mechatronics “aims to develop a complete domestic ecosystem around EVs” which have “zero tailpipe emissions” (Vision Mechatronics). 
Many electric vehicles are driven by lithium ion batteries which “can contain hundreds of individual cylindrical battery cells that are the same shape as common AA and AAA batteries” (Edmunds). They are extremely energy efficient and can store a multitude of energy; on full battery, electric cars powered by lithium-ion batteries can drive over 200 miles–although it may depend on the specific car model. Compared to their precursor, lead-acid batteries, lithium-ion batteries have higher energy density which increases the mileage of a car. They are also extremely lightweight and this ensures that EVs aren’t too heavy. Moreover, the electricity used to refuel the EVs come from renewable energy sources like solar power. 
The Environmental Cost of Battery Production
There are various concerns that lithium-ion battery powered cars take a long time to charge. Although this may be true for some models, recent developments have led to an increase in charging efficiency and overall energy storage. For instance, the Hyundai Ioniq 5 can be charged “from 10% to 80% in just 18 minutes” (Edmunds).
Moreover, the environmental impact that the creation of lithium-ion batteries has is detrimental as “the mining process for lithium and other materials used in these batteries can… lead to water pollution and habitat destruction” (Tara Electronics). Although this is the undeniable truth, it is promising to know that due to advancements in technology it has been shown that electric car batteries can “last 12 to 15 years in moderate climates”, meaning that they don’t have short lifespans (Edmunds). Moreover, “instead of ending up in a scrapyard like most internal combustion engines do, electric vehicle batteries can be repurposed, refurbished, or recycled when they fail” (Edmunds).
Building India's EV Ecosystem
Gupta believes that local battery production in India can help India progress towards an economy that is powered by clean energy. She mentions that it has been difficult to employ skilled labor in this field due to geopolitical tensions and a lack of awareness regarding the importance of this field. However, she is trying to bridge this gap by making opportunities in her company as accessible to the next generation as possible.

Unifying a Partisan Nation Around Nature
Nature is Nonpartisan is a bipartisan, solutions-focused coalition working to unite Americans around shared environmental goals. By fostering cross-party support for conservation and land stewardship, the organization hopes to reframe climate action as a unifying national priority rather than a partisan fight. 
Establishing Nature as Middle Ground
In recent years, environmental politics in the U.S. have been paralyzed by partisan gridlock, stalling climate progress. Nature is Nonpartisan aims to break this deadlock by reframing environmentalism around common-sense values, such as safety, access to the outdoors, and community well-being. By engaging Americans across the political spectrum, the coalition seeks to depoliticize climate solutions and ground them in conservation principles that resonate more universally: protecting public lands, supporting disaster-affected communities, and ensuring access to clean air and water.
This approach gained national attention in early 2025 when founder and CFO Benji Backer, alongside coalition members, briefed White House staff on nonpartisan conservation strategies. A meeting scheduled for fifteen minutes extended well over an hour, ultimately influencing President Trump’s unexpected June 2025 signing of the “Make America Beautiful Again” executive order. The order focuses on conserving public lands, safeguarding wildlife, and securing clean drinking water. Backer underscored that wildfires, drought, and ecosystem collapse don’t just affect the environment; they threaten billions in outdoor-recreation revenue and undermine the hunting, fishing, and farming traditions valued across political lines.
Nature is Nonpartisan’s narrative emphasizes that environmental protection is not only about climate, but also the American landscape, economic security, and the natural heritage millions rely on and cherish.
Conservation as Climate Action
Nature is Nonpartisan’s work centers on four key conservation areas: managing forests to reduce wildfire risk, enhancing water quality and improving water infrastructure, enhancing natural disaster resilience, and promoting responsible land stewardship. Together, these priorities offer a practical, bipartisan path to protect ecosystems and communities most vulnerable to climate change.
Overall, emphasizing conservation provides a widely palatable, bipartisan entry point into climate action. By restoring ecosystems, sequestering carbon, and protecting biodiversity, these efforts simultaneously strengthen local economies — particularly in rural regions dependent on recreation and natural-resource industries — while building long-term climate resilience. 
The Tension Beneath the Surface
Despite its promise, Nature is Nonpartisan’s work exists within a fraught political landscape. Environmentalism and conservatism are still often framed as ideologically incompatible, a perception the organization works actively to undo. While the “Make America Beautiful Again” executive order signals progress, critics argue it may be more symbolic than substantive, especially given President Trump’s longstanding dismissal of climate science. Some fear the order could serve more as a political performance than a genuine environmental advancement.
These tensions point to the broader challenge: decades of conservative skepticism toward climate science have made it difficult to ensure follow-through on policy. Nature is Nonpartisan hopes to continue confronting this distrust by reframing environmental protection around nationally shared values — family, future generations, clean water, clean air, and access to the outdoors — whether one is a Midwestern farmworker or a city resident.
The Power of Words and Bipartisan Policy
Communications Director Amelia Joy emphasizes that language is crucial to keeping these efforts genuinely nonpartisan. Because the word “climate” has become politically charged, Nature is Nonpartisan often avoids leading with it. Instead, Joy notes that many of the organization’s core priorities, from wildfire prevention to natural disaster resilience, are climate issues, but by centering them in everyday terms, the coalition can build durable, cross-party support that can outlast any single administration.
Policy Director Maya Cohn adds that progress doesn’t have to depend on who is in office. She emphasizes that policy advances can happen under any president or Congress if people are willing to work across political lines. For her, bridging divides and having honest conversations, even with those you disagree with, is the only way to create long-lasting environmental solutions.
