Sun’s Influence on Earth’s Deep Interior. Credit: Jiancong LiangSolar radiation affects Earth’s interior by changing the redox state of arc magma, influenced by the subduction of carbon-rich marine organisms. This discovery links surface climate variations directly to deep Earth processes. Scientists have long believed that changes in the Earth’s interior, such as volcanic eruptions and tectonic plate collisions, primarily affected the surface environment. Events such as the mass extinction around 66 million years ago and the transitions between icehouse and greenhouse climates were thought to be driven mainly by these deep Earth processes. Now, a new study published in Nature Communications has revealed a surprising new aspect: solar radiation can also affect the Earth’s deep interior. Impact of Solar Radiation on Marine Life and Subduction Solar radiation varies with latitude, creating temperature gradients on the sea surface that affect the distribution of marine life. These carbon-rich organisms are transported into the Earth’s interior by the subduction of oceanic plates. Researchers from the Institute of Geology and Geophysics of the Chinese Academy of Sciences have discovered that this process significantly affects the redox state of arc magma.

Vanadium and scandium levels of arc magma served as key indicators in the geochemical models. By compiling global geochemical data from Cenozoic arc magma and olivine-hosted melt inclusions, the researchers found a latitude-dependent redox distribution of arc magma with less oxidized magma in lower latitudes compared to those in higher latitudes.

The Sun’s Influence on Earth’s Mantle So how does the Sun work on the interior of the Earth? Further evidence came from seafloor studies, showing more reduced carbon deposits at lower latitudes. This carbon interacts with sulfur to form sulfide, which is then transported into the mantle, contributing to the observed redox pattern. “The observed pattern suggests a strong link between the surface environment and the redox state of the deep Earth, providing new directions for exploring the resources and environmental impacts of subduction systems at different latitudes,” said Hu Fangyang, corresponding author of the study. While the results are compelling, the researchers acknowledge the need for more extensive data from global marine and subducted sediments. The study opens new avenues for scientific exploration.

Costa Rica’s Tortuga Island Coral Garden Revives Reefs

The coral reefs off Tortuga Island in the Gulf of Nicoya are experiencing a remarkable revival, thanks to an innovative coral garden project spearheaded by local institutions and communities. Launched in August 2024, this initiative has made significant strides in restoring ecosystems devastated by both natural and human-induced degradation, offering hope amidst a global coral bleaching crisis. The project, a collaborative effort led by the State Distance University (UNED) Puntarenas branch, the Nautical Fishing Nucleus of the National Learning Institute (INA), the PROLAB laboratory, and Bay Island Cruises, has transplanted 1,050 coral fragments from June to September 2024, with an additional 300 corals added in early 2025. This builds on earlier efforts, bringing the total volume of cultivated coral to approximately 9,745.51 cm³, a promising indicator of recovery for the region’s coral and fish populations. The initiative employs advanced coral gardening techniques, including “coral trees” — multi-level frames where coral fragments are suspended — and “clotheslines,” which allow corals to grow in optimal conditions with ample light, oxygenation, and protection from predators. These structures are anchored to the seabed, floating about 5 meters below the surface. Rodolfo Vargas Ugalde, a coral reef gardening specialist at INA’s Nautical Fishing Nucleus, explained that these methods, introduced by INA in 2013, accelerate coral growth, enabling maturity in just one year compared to the natural rate of 2.5 cm annually. “In the Pacific, three coral species adapt well to these structures, thriving under the favorable conditions they provide,” Vargas noted. The project was born out of necessity following a diagnosis that revealed Tortuga Island’s reefs were completely degraded due to sedimentation, pollution, and overexploitation. “Corals are the tropical forests of the ocean,” Vargas emphasized, highlighting their role as ecosystems that support at least 25% of marine life and 33% of fish diversity, while also driving tourism, a key economic pillar for the region. Sindy Scafidi, a representative from UNED, underscored the project’s broader impact: “Research in this area allows us to rescue, produce, and multiply corals, contributing to the sustainable development of the region so that these species, a major tourist attraction, are preserved.” The initiative actively involves local communities, fostering a sense of stewardship and ensuring long-term conservation. This local success story contrasts with a grim global outlook. A recent report by the International Coral Reef Initiative (ICRI) revealed that 84% of the world’s coral reefs have been affected by the most intense bleaching event on record, driven by warming oceans. Since January 2023, 82 countries have reported damage, with the crisis ongoing. In Costa Rica, 77% of coral reef ecosystems face serious threats, primarily from human activities like sedimentation, pollution, and resource overexploitation. Despite these challenges, the Tortuga Island project demonstrates resilience. By focusing on species suited to the Gulf of Nicoya’s conditions and leveraging innovative cultivation techniques, the initiative is rebuilding reefs that can withstand environmental stressors. The collaboration with Bay Island Cruises has also facilitated logistical support, enabling divers and researchers to access the site efficiently. The project aligns with broader coral restoration efforts across Costa Rica, such as the Samara Project, which planted 2,000 corals by January and aims for 3,000 by year-end. Together, these initiatives highlight Costa Rica’s commitment to marine conservation, offering a model for other regions grappling with reef degradation. As global temperatures continue to rise, with oceans absorbing much of the excess heat, experts stress the urgency of combining restoration with climate action. The Tortuga Island coral garden project stands as a ray of hope, proving that targeted, community-driven efforts can revive vital ecosystems even in the face of unprecedented challenges.

More women view climate change as their number one political issue

A new report shows a growing gender gap among people who vote with environmental issues in mind.

A new report from the Environmental Voter Project (EVP), shared first with The 19th, finds that far more women than men are listing climate and environmental issues as their top priority in voting. The nonpartisan nonprofit, which focuses on tailoring get out the vote efforts to low-propensity voters who they’ve identified as likely to list climate and environmental issues as a top priority, found that women far outpace men on the issue. Overall 62 percent of these so-called climate voters are women, compared to 37 percent of men. The gender gap is largest among young people, Black and Indigenous voters. The nonprofit identifies these voters through a predictive model built based on surveys it conducts among registered voters. It defines a climate voter as someone with at least an 85 percent likelihood of listing climate change or the environment as their number one priority. “At a time when other political gender gaps, such as [presidential] vote choice gender gaps, are staying relatively stable, there’s something unique going on with gender and public opinion about climate change,” said Nathaniel Stinnett, founder of the organization. While the models can predict the likelihood of a voter viewing climate as their number one issue, it can’t actually determine whether these same people then cast a vote aligned with that viewpoint. The report looks at data from 21 states that are a mix of red and blue. Read Next Where did all the climate voters go? Sachi Kitajima Mulkey Based on polling from the AP-NORC exit poll, 7 percent of people self-reported that climate change was their number one priority in the 2024 general election, Stinnett said. Of those who listed climate as their top priority, they voted for former Vice President Kamala Harris by a 10 to 1 margin. The EVP findings are important, Stinnett says, because they also point the way to who might best lead the country in the fight against the climate crisis. “If almost two thirds of climate voters are women, then all of us need to get better at embracing women’s wisdom and leadership skills,” Stinnett said. “That doesn’t just apply to messaging. It applies to how we build and lead a movement of activists and voters.” Though the data reveals a trend, it’s unclear why the gender gap grew in recent years. In the six years that EVP has collected data, the gap has gone from 20 percent in 2019, and then shrunk to 15 percent in 2022 before beginning to rise in 2024. In 2025, the gap grew to 25 percentage points. “I don’t know if men are caring less about climate change. I do know that they are much, much less likely now than they were before, to list it as their number one priority,” he said. “Maybe men don’t care less about climate change than they did before, right? Maybe it’s just that other things have jumped priorities over that.” A survey conducted by the Yale Program on Climate Change Communication, a nonprofit that gauges the public’s attitude toward climate change has seen a similar trend in its work. Marija Verner, a researcher with the organization, said in 2014 there was a 7 percent gap between the number of men and women in the U.S. who said they were concerned by global warming. A decade later in 2024, that gap had nearly doubled to 12 percent. Read Next What do climate protests actually achieve? More than you think. Kate Yoder There is evidence that climate change and pollution impact women more than men both in the United States and globally. This is because women make up a larger share of those living in poverty, with less resources to protect themselves, and the people they care for, from the impacts of climate change. Women of color in particular live disproportionately in low-income communities with greater climate risk. This could help explain why there is a bigger gender gap between women of color and their male counterparts. In the EVP findings there is a 35 percent gap between Black women and men climate voters, and a 29 percent gap between Indigenous women and men. Jasmine Gil, associate senior director at Hip Hop Caucus, a nonprofit that mobilizes communities of color, said she’s not really surprised to see that Black women are prioritizing the issue. Gil works on environmental and climate justice issues, and she hears voters talk about climate change as it relates to everyday issues like public safety, housing, reproductive health and, more recently, natural disasters. “Black women often carry the weight of protecting their families and communities,” she said. “They’re the ones navigating things like school closures and skyrocketing bills; they are the ones seeing the direct impacts of these things. It is a kitchen table issue.” The EVP survey also found a larger gender gap among registered voters in the youngest demographic, ages 18 to 24. Cristina Tzintzún Ramirez, the president of youth voting organization NextGen America, said that in addition to young women obtaining higher levels of education and becoming more progressive than men, a trend that played out in the election, she also thinks the prospect of motherhood could help explain the gap. She’s seen how young mothers, particularly in her Latino community, worry about the health of their kids who suffer disproportionately from health issues like asthma. Her own son has asthma, she said: “That really made me think even more about air quality and the climate crisis and the world we’re leaving to our little ones.” It’s a point that EVP theorizes is worth doing more research on. While the data cannot determine whether someone is a parent or grandparent, it does show that women between ages of 25 to 45 and those 65 and over make up nearly half of all climate voters. Still, Ramirez wants to bring more young men into the conversation. Her organization is working on gender-based strategies to reach this demographic too. Last cycle, they launched a campaign focused on men’s voter power and one of the core issues they are developing messaging around is the climate crisis. She said she thinks one way progressive groups could bring more men into the conversation is by focusing more on the positives of masculinity to get their messaging across. “There are great things about healthy masculinity … about wanting to protect those you love and those that are more vulnerable,” she said. There are opportunities to tap into that idea of “men wanting to protect their families or those they love or their communities from the consequences of the climate crisis.” This story was originally published by Grist with the headline More women view climate change as their number one political issue on Apr 26, 2025.

Climate change could deliver considerable blows to US corn growers, insurers: Study

Federal corn crop insurers could see a 22 percent spike in claims filed by 2030 and a nearly 29 percent jump by mid-century, thanks to the impacts of climate change, a new study has found. Both U.S. corn growers and their insurers are poised to face a future with mounting economic uncertainty, according to the research, published on Friday in the Journal of Data Science, Statistics, and Visualisation. “Crop insurance has increased 500 percent since the early 2000s, and our simulations show that insurance costs will likely double again by 2050,” lead author Sam Pottinger, a senior researcher at the University of California Berkeley’s Center for Data Science & Environment, said in a statement. “This significant increase will result from a future in which extreme weather events will become more common, which puts both growers and insurance companies at substantial risk,” he warned. Pottinger and his colleagues at both UC Berkeley and the University of Arkansas developed an open-source, AI-powered tool through which they were able to simulate growing conditions through 2050 under varying scenarios. They found that if growing conditions remained unchanged, federal crop insurance companies would see a continuation of current claim rates in the next three decades. However, under different climate change scenarios, claims could rise by anywhere from 13 to 22 percent by 2030, before reaching about 29 percent by 2050, according to the data. Federal crop insurance, distributed by the U.S. Department of Agriculture (USDA), provides economic stability to U.S. farmers and other agricultural entities, the researchers explained. Most U.S. farmers receive their primary insurance through this program, with coverage determined by a grower’s annual crop yield, per the terms of the national Farm Bill. “Not only do we see the claims’ rate rise significantly in a future under climate change, but the severity of these claims increases too,” co-author Lawson Conner, an assistant professor in agricultural economics at the University of Arkansas, said in a statement. “For example, we found that insurance companies could see the average covered portion of a claim increase up to 19 percent by 2050,” Conner noted. The researchers stressed the utility of their tool for people who want to understand how crop insurance prices are established and foresee potential neighborhood-level impacts. To achieve greater security for growers and reduce financial liability for companies in the future, the authors suggested two possible avenues. The first, they contended, could involve a small change to the Farm Bill text that could incentivize farmers to adopt practices such as cover cropping and crop rotation. Although these approaches can lead to lower annual yields, they bolster crop resilience over time, the authors noted. Their second recommendation would involve including similar such incentives in an existing USDA Risk Management Agency mechanism called 508(h), through which private companies recommend alternative and supplemental insurance products for the agency’s consideration. “We are already seeing more intense droughts, longer heat waves, and more catastrophic floods,” co-author Timothy Bowles, associate professor in environmental science at UC Berkeley, said in a statement. “In a future that will bring even more of these, our recommendations could help protect growers and insurance providers against extreme weather impacts,” Bowles added.

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."

An academic woman in Texas becomes concerned when a massive red oak in her backyard seems to be ailing, though she isn’t sure why it bothers her so much. At the same time, in her small cottage, her attention to her work is distracted by news reports she sees and hears. They tell in graphic terms of the out-of-control forest fires up and down the West Coast. Her attention is further pulled in the direction of other stories about the worsening conditions of the world’s rainforests which she discovers are disappearing at the astounding rate of 200,000 acres a day. Suddenly such stories are all she seems to hear and see on the radio or television or on her computer. But when she hears/sees a science report about how trees actually communicate with each other, she begins to realize there may be a connection between her tree and what she is learning from the news. She begins to recall a strong connection she herself has with that tree and allows that connection to regrow…..

We Trees

Ever wonder what trees think of us now that we have created a climate disaster? This 2-minute film answers that question. As Bill McKibben recently tweeted about the film, “Who speaks for trees? In this short and elegant video, the trees themselves.” It has been screened at Green Fest (Serbia), The Colorado Environmental Film Festival, The Wildlife Conservation Film Festival and Winner of Merit at the Nature Without Borders Film Festival.

Rise and Fall

A film to provide an awareness of climate change and the individual measures we can take to combat it. The production process of Rise and Fall began as your stereotypical documentary meant to showcase various aspects of the Earth and Ocean Sciences Department at UNCW. Still, as the interview process was underway, it was quickly decided to move in another direction. It is an essay film about the science of climate change, what we can do in our day-to-day lives to combat it, and its impacts. Without using talking heads, the images of the natural world provide a sensual look at what will be affected by climate change.
