Heavy rains alter Peru's famed Nazca Lines
Lima (AFP) Jan 20, 2009 Heavy rains in recent days in Peru have affected the famed Nazca Lines, the two-millennia-old giant outlines that are one of the country's top tourist attractions, officials said Tuesday. The precipitation left a layer of white clay on parts of two of the geoglyphs, "giving another color to the figures," archeologist Mario Olaechea of the National Institute of Culture told AFP. But the changes were "reversible," he added. The Nazca Lines are considered one of the world's great mysteries. The geoglyphs, depicting people, animals and simple lines, are up to 200 meters (656 feet) long and can only be truly appreciated from the air. They were placed on UNESCO's list of world heritage sites in 1994, and thousands of tourists visit every year to see them up close. Share This Article With Planet Earth

Volcanoes Cool The Tropics
London UK (SPX) Jan 14, 2009Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics-but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. |
