earth's high-altitude glaciers in the tropical regions are in trouble. They might disappear soon, according to the first-ever comparison of climate records between the Himalayan and the Andean glaciers by a team of scientists from four universities in the us .

The scientists analysed ice cores and concluded that glacial retreat is occurring even in those tropical areas where there is increased precipitation. This suggests that rising temperatures and not decreasing precipitation is causing glacial melting. "About 70 per cent of the world's population lives in the tropics. When climate changes there, the impact will be enormous,' said Lonnie Thompson of the Ohio State University
