Multiple Choice Quiz on Global Warming

Greenhouse effect and ozone depletion are the two major environmental issues. The increased amounts of green house gases in the atmosphere are affecting the global climate. The climate change will increase threats to human health. Global warming will lead to changes in weather patterns and ocean currents.
