A message from Dr. Ye Tao

Looking ahead to the next phase of MEER's science, technology and global collaborations.

Dear Friends and Supporters,

As we move toward the end of another year, I wanted to take a moment to share a brief update on where we are with MEER and some of the exciting work taking shape for the months ahead.

After spending time in China, I traveled to New York in September for Climate Week, an important opportunity to reconnect with the wider climate community and exchange ideas on how we can accelerate practical solutions to the growing challenge of global warming.

I am continuing my stay in North America, meeting and engaging with scientists, researchers and potential collaborators as we consider the next phase of MEER's development. These conversations are helping us shape our strategy for the coming 12 months, particularly how we can strengthen our scientific research, advance our technologies and establish new partnerships that will support future demonstrations and wider deployment.

Much of our work at present is taking place behind the scenes, but progress continues across several important areas.

In Africa, we are continuing to build on the experience and knowledge gained through our field projects, refining our cooling systems and exploring opportunities for further demonstrations with local partners. These projects remain an important part of our work, particularly in understanding how affordable, passive cooling technologies can help communities facing increasingly dangerous temperatures.

Meanwhile, in China, our technical development continues to advance. We are working toward improving our reflective materials and radiative cooling technologies, with a particular focus on developing practical, affordable and durable solutions that can eventually be produced and deployed at scale.

We are also making encouraging progress in the engineering of our reflective canopy systems, exploring new approaches to their design, construction and installation. Over the coming year, we hope to bring these different strands of research and development together through further testing and carefully planned demonstrations.

Alongside these practical developments, our scientific research continues to evolve. We are refining our understanding of how different surfaces reflect incoming solar radiation, how radiative cooling can contribute to reducing heat accumulation, and how these effects can be more accurately measured and modeled. This work is fundamental to MEER's long-term vision, helping us better understand both the local cooling benefits of our technologies and their wider potential to contribute to restoring Earth's energy balance.

One of the most encouraging aspects of this journey has been the growing network of scientists, engineers, researchers and supporters who share our belief that practical, scalable approaches to cooling deserve much greater attention. Strengthening these collaborations will be a central priority as we move into 2027.

While there is still much work ahead, I remain optimistic about the direction we are taking. Developing new technologies and translating scientific ideas into practical solutions takes time, patience and careful testing. Each stage brings new lessons, and each improvement helps move us closer to our goal of making effective passive cooling accessible to communities around the world.

As always, I would like to express my sincere gratitude to everyone who continues to support MEER, whether through research, collaboration, financial contributions or simply by helping share our work and ideas.

Your encouragement and commitment make this journey possible, and I look forward to sharing further developments with you in the months ahead.

With warm regards,
Dr. Ye TaoFounder and Science Director

Policy news

IMO adopts frameworks to assess marine geoengineering research activities

New guidance gives governments a precautionary framework for evaluating research proposals and protecting the marine environment.

Illustration of marine carbon dioxide removal approaches: mineral addition from a ship, artificial upwelling tubes, microalgae fertilization, sinking of macroalgae or crop waste to the seabed, an electrochemical facility on the coast and direct ocean removal from a coastal tank.
The marine approaches now covered by the new frameworks: mineral addition, artificial upwelling, microalgae fertilization, sinking of macroalgae or crop waste, electrochemical alkalinity enhancement and direct ocean removal.

Parties to the London Convention and London Protocol adopted new assessment frameworks at the International Maritime Organization (IMO) in London during their October 5 to 9, 2026 meetings. The guidance covers ocean fertilization, ocean alkalinity enhancement and the sinking of biomass, approaches intended to increase ocean carbon uptake or store carbon for long periods.

Governments will use the frameworks to assess whether proposals constitute legitimate scientific research and can proceed without unacceptable risks to the marine environment. Each framework covers initial screening, environmental assessment, risk management, decision making and review after the project.

Research, not a green light for deployment

Proposals must demonstrate a legitimate scientific purpose, assess environmental risks, include stakeholder consultation and peer review, and provide rigorous monitoring and transparent reporting. The Parties stressed that scientific knowledge remains limited and further research is needed before activities beyond the research stage can be considered.

These frameworks address marine carbon removal research, rather than reflective surface cooling. They highlight the importance of environmental safeguards as climate intervention research develops.

Novelty Tech

Ceramic cubes that cool with water, not electricity

Researchers at Graz University of Technology in Austria have developed porous, 3D printed ceramic cubes that absorb water and release it slowly. As the water evaporates, it draws heat from the surrounding air without using electricity for the cooling process.

In a test in a hot attic, the team reported a temperature drop of nearly 13°F (about 7°C). Outdoor demonstration installations in Graz are exploring how the cubes could work as part of walls and other structures. It is an intriguing early experiment, not yet a proven replacement for air conditioning.

Breaking the Climate Deadlock: A Viable Strategy for a Divided World

With Dr. Graeme Taylor and Suzanne Reed

Climate risks are accelerating, yet the transition away from fossil fuels remains slow. Dr. Graeme Taylor and Suzanne Reed explore how climate solutions can advance in a divided world, and how international cooperation can help prevent dangerous climate overshoot.

As climate disasters intensify and food security deteriorates, major powers may consider solar geoengineering, potentially through unsafe unilateral action. The speakers examine why coordinated research and governance are urgently needed to assess possible cooling interventions as a supplement to emissions reductions and carbon removal.

Drawing on their work on climate overshoot and climate stabilization, they propose a strategy for overcoming negotiating deadlock. A 20 minute illustrated presentation is planned, followed by discussion, subject to the confirmed running order.
