Peruvians painted mountains with new creative white paint to slow down the melting of glaciers
in the Andes mountains of Peru, several people carried water bottles and splashed white paint on exposed stones on the hillside. They plan to paint parts of the three peaks white in the hope that this will slow the melting of glaciers and protect the earth's ecological environment. However, some scientists and government officials doubt the utility of this move
■ Tushan plan
Tushan is the creativity of Peruvian Eduardo gold. For this reason, he won the world bank's "100 ideas to save the earth" award in November 2009, and received US $200000 in funding. Gold plans to partially whiten the three peaks of the Andes in Ayacucho Province in southern Peru, covering a total area of 70 hectares, starting from Mount chalonson brero. He recruited 4 people from the local likapa village to start the mountain painting project together
everyone used a kettle, loaded with an environmental friendly coating made of lime, industrial protein and water, and sprinkled it on the rocks on the hillside. At present, they have painted about 2 hectares
quote Gold: "the white surface reflects the sun's rays back to the atmosphere and the universe, which makes the surroundings cooler."
"in fact, this is creating a microclimate. So we say that cold breeds more cold air, just as hot breeds more heat," he said
U.S. Secretary of Energy Steven Chu may be a confidant of gold. Chu agreed that American buildings should adopt white roofs to help cope with climate change
■ local support
"with fast operation speed, we are likely to rebuild a glacier by doing so, because we will rebuild the necessary climatic conditions for glacier formation," gold said
Chalon Sombrero was once a glacier, the birthplace of a river valley and several rivers. Pablo Palco Palomino, a 65 year old villager in licapa, witnessed the transformation of Mount chalonson brero from snow to bare stones
likapa village is located on this mountain, with an altitude of more than 40 meters, which directly affects the normal operation of the safety barrier. As crops and trees cannot grow at this height, villagers mainly sell alpaca wool for a living. Palomino said that climate change has made the lives of more than 900 people in the village more comfortable. This product has the outstanding advantages of short charging time and large battery capacity. It is difficult and may be forced to leave their homes and move elsewhere
"all the peaks here should be painted like this," he said. "Then there may be as much water here as before the disappearance of the glacier, which means more pastures and more livestock. After the project is completed and passed the acceptance"
like Palomino, most villagers welcome gold's mountain painting project and hope that bald mountains will turn back to glaciers
■ question the effect
although the intention is good, some scientists doubt whether painting the peaks white can actually alleviate or reverse the melting of glaciers
thomascondon, a glaciologist and hydrologist at the Development Institute in Lima, France, has been observing the tropical glaciers in the Andes for the past 15 years. He said that gold's Tushan project may have a certain impact on a small scale, "it may slow down the melting rate slightly, and may reduce the local temperature by a few tenths of a degree Celsius, or one or two degrees Celsius"
Kongdong said that temperature and reflected light are not the only factors affecting glaciers, and sediment is another key factor. In addition, it is very difficult to implement this project on a large scale
according to the data released by the world bank in 2009, Peru has 70% of the world's tropical glaciers, of which 22% have melted in the past 30 years due to global warming
Antonio Braque, Minister of environment of Peru, commented on the Tushan project with the word "absurd". He said that if the World Bank funded other projects with us $200000, it may achieve greater results in alleviating environmental degradation
