The greenhouse effect that may be cooling the climate - earth - 10 October 2008 - New Scientist Environment: "HERE is one greenhouse effect that is welcome: the roofs of hothouse farms in Spain reflect so much sunlight that they may be pushing down local temperatures.
Since the 1970s, semi-arid pasture land in Almeria, south-eastern Spain, has been replaced by greenhouse horticulture. Today, Almeria has the largest expanse of greenhouses in the world - around 26,000 hectares."
Hat-tip to Nouslife, who comments: "Of course, the effect of this agriculture on the water table is another story."
