Chapter 6. 4: Meeting Ecological Challenges Case Study #3 (Pgs

Recognizing a Problem Evidence shows that the Earth’s temperatures are getting warmer, sea ice is melting, and sea level is rising Animal and plant activities are changing in response to warmer temperatures

Researching the Cause Scientists determine if it is a natural cycle or if there is a manmade cause Correlations between human activity and greenhouse gases indicate that climate change is manmade Scientists create models to show how much change is possible and what effects may happen Flooding or drought Increase in size of some deserts Thawing of polar ice caps

Changing Behavior To stop global warming we must reduce the amount of greenhouse gases we put into the atmosphere Drive electric or hybrid cars Make buildings that use less electricity Increase recycling
