What are the effects of CO2 emissions

Increasing carbon dioxide emissions cause about 50-60% of the global warming. Carbon dioxide emissions have risen from 280 ppm in 1850 to 364 ppm in the 1990s. It is suspected that global warming may cause increases in storm activity, Melting of ice caps on the poles, which will cause flooding of the inhabited continents, and other environmental problems.

CO₂ can contribute to acid rain in much the same way that CO₂ in soft drinks and beer makes those beverages acid. Pour a glass and drop a nail in it for a nice visual. Check back in a day or so and see what's left of the nail! Acid rain is not good for trees. CO₂ also contributes to smog in cities such as China’s smog problem.
