Choose a Continent
· North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.
· Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.
· Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
· Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.
· Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions.
How will climate change affect the Earth?
1. Describe at least two species that will become endangered or extinct on this continent and explain why.
2. Describe the overall prediction of the climate with moderate (2 degree increase) and severe (4 or more degrees) warming.
3. What will this new climate mean in terms of the current Biome, or Biomes present? Will there be desertification? Loss of forest? Conversion of forest to grassland? Be specific about what the future landscape will look like in terms of vegetation and location.
4. Describe the impact on the human population including a discussion of at least 3 of the following: Food sources, Rising sea level, Severe weather or storms, access to water or drought conditions, specific populations that might be severely impacted (Ex: Coastal Areas, migrant workers, indigenous people), and increased frequency and intensity of wildfire.
