MEER: Cooling Earth by Reflecting Sunlight

Join us to reduce global temperatures by 1-2ºC while delivering local heat relief.

MEER is ready for deployment and can be constructed entirely of recycled materials.

Temperature rise is the biggest threat to the urban environment, agriculture and water resources

MEER designs and deploys surface solar reflectors, which can be made from recycled materials, in an economically feasible and environmentally sensitive way.  Locally, they are used for heat adaptation purposes. Globally, the reflectors provide thermal mitigation to partially rebalance Earth's energy.

What are the major problems as the Earth overheats?

urban heat icon
Urban Heat
Using MEER mirrors can reduce indoor temperatures by 5-7ºC, which can provide instant relief.
agriculture icon
A 1ºC increase in temperature results in increased soil dryness. Food production has already decreased by 10% due to heat and is expected to worsen.
Using MEER mirrors can help to reduce evaporation and increase farm productivity.
water reservoirs icon
Water Reservoirs
Global heating is causing more freshwater to evaporate from reservoirs, exacerbating the already dire lack of drinking water access for 2 billion people worldwide.
Placing MEER mirror reflectors on reservoirs can reduce evaporation by 50-90%, resulting in more drinking water availability.

Global benefits from MEER

global warming icon
Temperatures have risen by 1.2ºC with another 1-2ºC of heating locked in. This will have a significant impact on ecosystems and all living things.
At scale, MEER surface reflection technology can prevent this additional heating of 1-2ºC.
