Major Points Air Pollution and climate Change a
re linked through Aerosols Tropospheric Ozone
Focus on the Problem Regionally Define the
Regions Tropics is a Large Source for
Black carbon Asia, Africa and Amazon
Emphasize the Hydrological Cycle Water availab
ility is the Major Environmental Issue for this
century
