In 2010, workers painted part of a Peruvian mountain white to regrow its lost glacier; the World Bank selected the idea for a $200,000 grant

A climate experiment in Peru involved whitewashing a mountain to encourage glacier regrowth. This effort aimed to increase sunlight reflection and cool the mountain's surface. The theory relied on the albedo effect, where bright surfaces reflect more solar energy. While the project showed increased reflectivity, it did not restore the glacier. This creative idea underscored the urgent search for solutions to glacier loss globally.
