Yerupaja mountain in the high Andes may be one area to be painted white after glaciers melt.

A Peruvian scientist told his country’s parliamentary commission on climate change that global warming could be combated by painting highly reflective white paint over rock and ground exposed by receding glaciers.

Eduardo Gold, president of Glaciers of Peru, says reflecting the sunlight would keep the ground from absorbing as much solar radiation.

He proposes using only environmentally friendly lime-based paint made without harmful chemicals.

His scheme has drawn interest from the World Bank, which is considering various “geoengineering” proposals to counter climate change.

Gold says hiring local residents to do the landscape painting could create about 15,000 jobs.

The glaciers of the tropical Andes have proven to be very sensitive to climate change.

Some scientists have estimated a loss in coverage of more than 30 percent over the past 30 years.
