“Listening to the Climate” : A Reflection on ClimaSynth
Climate change has become an overwhelming topic, often measured in numbers, graphs, and satellite images. But what if we could hear its effects instead? That’s the core question behind ClimaSynth, a web-based sonic interface developed by Eleni-Ira Panourgia, Bela Usabaev, and Angela Brennecke. Their paper, presented at NIME 2024, explores how environmental perception can be enhanced through real-time audio interaction, using granular synthesis to sonify future climate scenarios.
As someone researching the intersections of sound, interaction design, and environmental awareness, I found ClimaSynth to be both conceptually rich and technically compelling.

Where ClimaSynth Shines
ClimaSynth isn’t just a tech demo, it’s a poetic instrument. Users interact with environmental recordings through a minimalistic web interface, manipulating sounds that morph depending on climate data and speculative futures. For instance, a serene “birds near water” recording can gradually transform into insect-heavy textures, mimicking a sonic shift tied to rising temperatures and drought. These transformations are not just aesthetic, they’re emotional cues for users to reflect on environmental degradation.
The choice to make ClimaSynth a web application is a smart one. It emphasizes accessibility, allowing anyone with a browser to engage with the experience, regardless of device or platform. This aligns beautifully with the ethos of broadening climate awareness beyond academia and into more public, participatory domains.
Another aspect I appreciated was how the team uses climate storytelling prompts in the interface. These small bits of narrative—like “trees readjusting their flexibility”—help ground the abstract sound manipulations in relatable ecological imagery. It’s a great example of how interface design can nudge user interpretation without being didactic.
Also worth highlighting is a thoughtful and often overlooked section: the ethical standards. The authors openly acknowledge the environmental cost of building web and cloud-based tools—specifically their energy demands and carbon footprint. It’s refreshing to see this kind of transparency and accountability in a digital art and research project. They even reflect on how publishing the app on GitHub (a platform supporting sustainable software practices) contributes to a more positive “handprint.” This attention to how the work is made—not just what it does—adds another layer of credibility and care to the project.
Where the Paper Left Me Wondering
While the system and concept are well-executed, I couldn’t help but feel a bit of a gap in understanding who exactly ClimaSynth is for. Is it a tool for public engagement? An artistic instrument? An educational platform? The authors mention “communicating climate change impacts,” but more clarity around the target audience or use-case scenarios could strengthen the work’s purpose.
Defining a user persona or community—whether that’s students, environmental activists, museum visitors, or musicians—might guide future iterations and also offer pathways for more impactful deployment. For example, if ClimaSynth is intended to foster awareness among high school students, it might benefit from a more guided interface or educational context. If it’s for artists, perhaps more export and remix functionality would be useful.
Similarly, I’m curious how ClimaSynth would perform in a collaborative or public setting. Could this be scaled into an installation? Could multiple users interact with it simultaneously? Could it be a live performance tool? These are all exciting possibilities that hint at ClimaSynth’s potential, but aren’t fully explored in this first prototype.
Final Thoughts
Overall, ClimaSynth is an inspiring step forward in the space where sonic interaction meets climate awareness. It reminds us that listening is a powerful way of knowing—and that sound can be both data and emotion, fact and feeling. In an age where climate anxiety often paralyzes, interactive tools like ClimaSynth offer a more intuitive, embodied way to reconnect with the world around us—and imagine what it might become.
As the project evolves, I’d love to see deeper engagement with users, clearer audience intentions, and expanded sonic possibilities. But as it stands, ClimaSynth is a meaningful addition to the growing field of eco-acoustic design.
