In an age of global climate change, with shifting rainfall patterns, changing reflectivity holds appeal.
The causes are not known, but the suspects are hotter and drier weather, or shifting rainfall patterns.
It asks both rich and poor countries to take action to curb the rise in global temperatures that is melting glaciers, raising sea levels and shifting rainfall patterns.
Rising temperatures and shifting rainfall patterns pose particular problems to an industry which is so sensitive to weather that even mild seasonal variations can be tasted in every glass of the final product.
This week, research sponsored by government-funded international science research group CGIAR concluded that higher temperatures and shifting rainfall patterns will bring further uncertainty and change to river basins in Africa, including the Nile.
{Associated Press] Rising global temperatures and shifting rainfall patterns could affect water flows on Africa's Nile and Limpopo rivers, raising the risk of conflicts between Botswana, South Africa, Mozambique and Zimbabwe in a region that is already chronically dry, a study says.
These changes coincided with shifting rainfall patterns over East Africa.
These are all components of the planet's integral makeup, and when damaged in this way, they will trigger defensive feedback mechanisms: rising temperatures, shifting rainfall patterns, and increased sea levels, among other reactions.
