Pollution Reduces Rainfall over hills in semi-arid regions

ScienceDaily (March 9, 2007)

Manmade climate change due to pollution seriously inhibits precipitation over hills in semi-arid regions, a phenomenon with dire consequences for water resources in the Middle east and many other parts of the world

Illustration shows (at left) a cloud with normal foundation of rain droplets, while at right the droplets do not form readily because of the small particles caused by pollution. The water vapor condenses on the pollution particles and creates a cloud with a large number of drops that are so small that they float with the air and are slow to coalesce into raindrops or to freeze into sleet and snowflakes.
