Greenhouse gases in the atmosphere have raised global temperatures by 1.2-1.5C, posing a risk of ecological disaster. To address this, we need to prioritize climate mitigation and reduce temperatures. Geoengineering methods, like MEER, are necessary to restore ecosystems and create a habitable environment. International support and funding are crucial for large-scale implementation

Climate change

Through years of observation, theory development, and model building, scientists have gained a deep understanding of the Earth's climate system. It is now widely accepted that human activity, specifically greenhouse gas emissions, is causing climate change. 

The Earth is experiencing a significant positive energy imbalance. This imbalance is storing 400 Terawatts of heat in the ocean and atmosphere, which is twenty times more than the energy used by human civilization. This has caused a warming trend known as global warming or anthropogenic climate change. Many researchers and the general public are becoming increasingly concerned about the potential for extreme weather events, heat strokes, droughts, crop failures, internal displacement, and ecosystem collapse. This phenomenon has the potential to cause widespread suffering within the lifetimes of most of the Earth's human population. We can confidently say that the impacts of climate change are already being felt and will only continue to worsen in the future.

Ground-based technology

MEER has come up with an innovative solution to tackle the issue of rising temperatures on both a local and global scale. Our technology involves reflecting sunlight into space to reduce heat, which has been proven to be effective and efficient. All-white or light-colored objects exhibit the albedo effect to varying degrees. MEER's reflectors have an equal to or greater albedo than other options. Ground-based technology is a reliable option for extended periods and can be locally tested. It offers a highly precise adaptation infrastructure that provides immediate and controllable benefits in a specific area. However, to achieve significant global effects, a coordinated effort is required from countries and organizations worldwide. This may be due to a need for increased manufacturing capacity or a need for more suitable implementation areas.

Controlling global warming

We must consider past and future emissions to mitigate climate change effectively. The scale of our mitigation strategy will depend on this. Greenhouse gases already present in the atmosphere will continue to contribute to warming. Thus, it's essential that we implement MEER reflector installations to counteract the warming effect of future emissions and also address the warming currently masked by anthropogenic aerosols. This will become even more crucial if we achieve 100% carbon neutrality by 2100.

To limit these global temperature increases to 1.3 C, we need to dedicate more land to natural reflective surfaces. This means 24% of Earth's agricultural land or 2.4% of Earth's total surface area. If we want to limit the temperature increase to below 2°C by 2100, we can allow for an extra 0.8 W per m2 of heating power. We need to aim for a new cooling target of -1.5 W per m2 to achieve this. In this case, only 15% of Earth's agricultural land or 1.5% of Earth's total surface area is required.

Cooling local areas

MEER has the capability to cool local regions and cities by increasing their level of albedo. Albedo refers to the amount of sunlight reflected by a surface. Villages and towns are primarily composed of various buildings. MEER proposes that by placing reflectors on top of a home, the structure and the air inside it can be cooled. This is because the reflectors will reflect a portion of the sunlight back into the atmosphere, consequently reducing the amount of heat the building absorbs. The same applies to other structures or areas, such as barns, playgrounds, or any surface or area covered by a reflector. Scaling this up to a community level, we anticipate the cooling effect extending over a larger area as reflectors cover more and more surfaces. MEER is currently constructing a community-level experiment in Sierra Leone to demonstrate this theory. The experiment will involve placing reflectors on various surfaces within a community and measuring the temperature difference before and after their placement. The aim is to demonstrate the effectiveness of this method in reducing temperatures in hot regions and how it can be implemented on a larger scale to combat the effects of climate change.

Efficiency and recycling

In every city, one can often find waste in the form of plastic, glass, and aluminium cans scattered around. The global scaling cycle aims to address engineering tasks related to global warming on a global scale but frequently requires more material than is available. However, certain materials are abundant and viewed as trash, even though they could be valuable resources. These items could be utilized for building infrastructure. MEER can use 100% recycled materials, specifically repurposed PET plastics and aluminium that are unfortunately discarded in landfills, to meet our annual material requirements. By doing so, we not only decrease our environmental impact but also contribute to the preservation of our planet's natural resources.

We recently developed a prototype for an agricultural infrastructure to increase soil fertility, which continues to decline due to water evaporation caused by increased CO2. This prototype primarily uses PET sheeting made from recycled plastic bottles supported by bamboo. The reflector layer is made from coated aluminium to prevent corrosion, and the cordage is made from cut and stretched plastic bottles. For every 10 square meters of mirror sheeting, we can cancel out the heating effects of one ton of CO2 in the atmosphere. Additionally, the infrastructure has a negative embodied carbon due to the carbon stored in the bamboo and the specialized treatment of the material. We conducted an assessment of discarded resources in plastic, glass, and aluminium cans and found that we could produce this prototype on a large enough scale to negate the heating effects of contemporary CO2 emissions.


To create effective mitigation plans, it's essential to develop durable solutions that can last for an extended period without needing to be recycled. This is crucial because the energy required for adaptation and mitigation must be taken into account. Many mitigation plans require ongoing energy input, which can be problematic as energy is a limited resource.

Indoor mirrors typically have a lifespan of centuries, while outdoor mirrors can last for decades. MEER intends to utilize other reflectors that are also expected to last for many years, considering wear and tear from weather, airborne dust and dirt, bird droppings, and similar factors. However, these projections do not include unforeseen accidents and extreme weather events. The PET sheeting developed by MEER boasts properties enabling it to last even longer outdoors. This sheeting includes anti-soiling agents, which help maintain a higher albedo level for extended periods compared to white paint, among other things. It is also designed to be self-cleaning, allowing it to be washed naturally by rainwater without the need for manual intervention or increased energy consumption. We anticipate the mirror sheeting will remain in good condition for 5 to 15 years. The evidence suggests that the sheeting is much better than painted surfaces.

Passive Technolgy

MEER's Passive design aims to enhance the comfort and well-being of occupants by responding to the unique climate and site conditions of the area while also minimizing energy consumption. To achieve this, it is crucial to make the most of the local climate. Passive cooling involves utilizing our technologies to lower building temperatures without relying on power consumption. Once our reflectors are deployed in the field, they require no additional energy to function. They are passive and do not rely on any power source.

Carbon Footprint

The strategy employed by MEER is highly efficient when it comes to reducing CO2 emissions. The carbon and energy footprints associated with the production and use of solar reflectors are significantly lower than those of other mitigation methods. 

The use of reflectors to cool soil has numerous advantages, including the reduction of CO2 emissions. This innovative technique is particularly effective in agriculture, where cooling the land can prevent soil from leaching carbon. By lowering the temperature of the soil, less carbon is released into the atmosphere, thereby minimizing the negative impact of greenhouse gases. Not only does this technique have environmental benefits, but it also contributes to improving soil quality, resulting in better crop yields and healthier ecosystems.

In addition, employing passive cooling technology in residential buildings leads to a significant decrease in carbon energy consumption when compared to conventional mechanical cooling systems, which typically require a substantial amount of energy to function. This environmentally conscious approach to cooling not only reduces a household's carbon footprint but also helps conserve energy and promote sustainability. 

There are various methods of sequestering carbon by cooling water and other means, and MEER is currently exploring many of these possibilities.


MEER technology will lessen the impact of global and local warming. By reflecting sunlight back into space, MEER has the potential to reduce the amount of heat absorbed by the Earth's surface, which can help to mitigate the effects of global warming. In contrast to other adaptation and mitigation methods, MEER is simple to implement and can be carried out democratically. This means virtually any community or nation can adopt this strategy, even with a limited budget. The need for this cooling option is becoming increasingly prevalent every year as global temperatures continue to rise. With MEER, cost-effective and simple solutions can be provided to parts of the world that desperately need them.
