  3. CAUSES Industrial revolution. Abnormal Green House Gases (GHG). GHG block return of sun’s rays to atmosphere.

  4. This raises globe’s temperature. Temperature rise evaporates more water forming clouds.

  5. Clouds produce variability in seasons:- • Change in monsoon pattern. • Increase in intensity. • Change in timing.
