temperature of the earth's atmosphere
generally attributed to the greenhouse effect
caused by increased levels of carbon
dioxide, chlorofluorocarbons, and other
pollutants

4. • a gas in an atmosphere that absorbs and sends out
radiation within the thermal infrared range. Greenhouse
Gases occur in nature are water vapor, carbon dioxide,
methane, nitrous oxide, and ozone

5. • The term ozone depletion is used to describe the steady
corrosion and depletion of the ozone layer which is
thought to have begun in the 1970s. This phenomenon
has led to the development of holes on the ozone layer.

8. • The number of category 4 and 5 storms has greatly
increased over the past 35 years, along with ocean
temperature.
• Hurricane Katrina of August 2005 was the costliest and
one of the deadliest hurricanes in U.S. history and
caused economic losses in the order of $125 billion.

9. • Scientific studies show that a higher level of carbon
dioxide spurs an increase in the growth of weeds such as
ragweed, whose pollen triggers allergies and
exacerbates asthma.
• Rising temperatures increase ground-level ozone smog
production, which presents a serious threat to
asthmatics.

10. • Increasing global temperatures are expected to disrupt
ecosystems, pushing to extinction those species that
cannot adapt. The first comprehensive assessment of the
extinction risk from global warming found that more than
1 million species could be obliterated by 2050 if the
current trajectory continues.
These animals are
soon to be
EXTINCT.

11. • Rising global temperatures will speed the melting of
glaciers and ice caps and cause early ice thaw on rivers
and lakes.
• According to NASA, the polar ice cap is now melting at
the alarming rate of nine percent per decade. Arctic ice
thickness has decreased 40 percent since the 1960s.
