Source of dust key to ice forming in clouds, should be included in climate models: Scientists

Dust particles from river deltas can more potently influence ice formation in clouds than those from deserts, researchers have found. At low temperatures, atmospheric dust particles are known to enable the aggregation of ice particles to form ice crystals in clouds. In the absence of dust, called ice-nucleating particles, water in clouds can remain in liquid form despite freezing temperatures.
