Can painting rocks save the glaciers?

Having watched the sheets rolled on the glaciers to protect them from the harsh summer heat / sun and having seen in countless mountain huts the extent of the glacial retreat from pictures taken earlier last century, I have often wondered if humankind really understands the immense loss we are soon to engineer. I can take or leave summer glacier skiing although skiing powder from October to June each year is something that I hold dear. The wider knock-on effect of their disappearance will make my recreation loss seem pretty trivial I am sure. I read recently about a pioneering project in Peru where the rocky terrain that once was home to a glacier was being effectively white-washed in order to create a cooler micro-climate that would encourage the reformation of the local glacier. The beneficiaries were not skiers but locals who relied on natural reservoirs to irrigate their lands throughout the year. For the last week or so I have been mulling this idea in the fierce heat of a hot European summer. If it works it is absolutely inspired - not nearly enough to prevent climate catastrophe but on a local level it could be a brilliantly novel solution. The simplicity of the idea of painting the rocks (with organic materials) is worrisome given the magnitude of the problem. Yet if our leading powers still set their technology horizons at burning coal (in the case of China) and the need for hazardous Gulf of Mexico oil (in the case of the USA) to power inefficient cars then maybe painting mountainsides is an entirely contemporary solution?
