A New Documentary Coming in 2027
An intimate journey into the growing threat of extreme heat and the scientists, communities and innovators working to develop practical climate solutions.
Watch the Official Trailer
An early preview of the forthcoming feature documentary. The full film is still in production — this trailer is a first look at the material we have captured so far.
Please note: this is not the complete film. The trailer represents a small selection of footage from an ongoing production, and additional filming, editing and post-production work is continuing.
A feature-length documentary, currently in production.
This forthcoming documentary follows MEER's work across multiple countries as communities respond to one of the defining challenges of the twenty-first century: extreme heat.
Filmed on active project sites and shaped alongside the scientists, engineers and community leaders driving that work, it moves between the laboratory, the rooftop and the classroom to explore what it actually takes to cool a warming world.
Themes woven throughout the film include:
- Climate science
- Innovation
- Field research
- Community resilience
- Practical climate solutions
- The human stories behind the science
Coming in 2027.
An approximately 90-minute feature documentary. Currently in post-production, with planned submissions to international film festivals followed by a wider public release. The full schedule will be announced here once it is confirmed.

What to expect.
The film is still being cut, so we are not sharing chapters yet. These are the themes the documentary explores.
The growing threat of extreme heat
How rising temperatures are reshaping daily life across five continents.
Climate science explained
The physics of surfaces, radiation and Earth's energy balance, made accessible.
Communities adapting to rising temperatures
The people quietly rewriting what resilience looks like on the ground.
Innovative cooling technologies
Materials and methods being trialled from Freetown rooftops to Californian labs.
Scientific field research
Instrumented rooftops, thermal flights and the discipline of measurement.
Hope through practical action
What changes when a community decides not to wait.
Inside the production.
We are documenting the making of the documentary as it happens. Production stills, filming locations, interviews with the filmmakers and behind-the-scenes photographs will be added here as the film comes together.
This section will grow throughout production. Check back for new stills, location diaries and interviews with the crew.

Our original 2024 documentary.
See where the journey began.
Before our new documentary was produced, this original film introduced MEER's early work, our first field deployments, and the vision that launched the organization. While much has changed since 2024 — including our technologies, research program and global activities — it remains an important record of our early development and the foundations of our mission.
