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
350.org
mid-century. But the longer we
remain 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
