Chhattisgarh: Industrial Jungle

CSE released its cover story on the rapid industrialisation in Chhattisgarh on November 15, 2010 at Raipur, Chhattisgarh. The event was organised by Ekta Parishad. The cover was based on a detailed analysis of the proposed industries in the state, their land and water requirement and whether that state will be able to meet this requirement.

Origin of aerosols dictates cloud shape

How cloudy is it outside? The answers may depend on the level of atmospheric pollution in one’s region. Cloud-forming microscopic particles, called aerosols, absorb and reflect solar radiation. These particles have the ability to modify cloud formation and encourage or suppress precipitation. They can be released from manmade sources like vehicles, industry, agriculture, and natural sources like sea salt, volcanic dust, sulphates from biogenic gases.
