1. Global Point of View
AP Environmental Science
Heathwood Hall Episcopal School
Columbia, South Carolina
2. Definition of Problem
Global Status Quo
• Population increases have contributed excessive
greenhouse gas emission, waste, and degradation of
natural capital
• Current climate trend has resulted in warmer and drier
conditions
• Increase in extreme weather events such as droughts and
heat waves
• A decrease in precipitation affects natural resources,
human health, and water resources
3. Definition of Problem
Global Status Quo
• Shorter duration of snowfall each year
• Water levels are rising, particularly in more isolated bodies of water,
like the Baltic Sea
• Plants have moved northwards due to the warmer climate
•The economy has suffered serious losses in the past twenty years
because of extreme weather events
•―Climate models predict that the average temperature at the Earth's
surface could increase from 3.2 to 7.2ºF above 1990 levels by the end of
this century‖ (http://www.epa.gov/climatechange/basicinfo.html)
4. Definition of Problem
Global Target Situation
•‖By decreasing use of other fossil
fuels, and improving agricultural
and forestry practices around the
world, scientists believe we could
get back below 350 by mid-
century. But the longer we remain
350.org
in the danger zone—above 350—
the more likely that we will see
disastrous and irreversible climate
impacts.‖ – James Hansen, NASA
5. Reasons and Causes of the Problem
Global
•Government laws are in place to reduce CO2 emissions, but they are
avoidable to a point because of weak enforcement
•Factories, large cities, cars, landfills, waste treatment methods, the
importation of many goods, farmyard animals cause the burning of
harmful fossil fuels
6. Consequences of the Problem
Global
• Rising sea levels
• Hotter summers
• Serious health hazards for humans caused by increase in SO2
• Changes in precipitation
• Possible natural disasters
• Wind currents could change
• Delicate ecosystems could be irreversibly damaged
• Decrease in biodiversity
7. Possible Countermeasures
Global
• Switch to renewable forms of energy such as
hydroelectricity, wind, and solar
• Government laws that would enforce stricter
regulations on greenhouse gas emissions
• Greener and smarter transport systems
• Creation of cap-and-trade programs for
greenhouse gas emissions
