2. WHAT IS GLOBAL WARMING?
Global warming is the term used to describe a
gradual increase in the average temperature
of the Earth's atmosphere and its oceans
3. GLOBAL WARMING
Global warming is primarily a
problem of too much carbon
dioxide (CO2) in the
atmosphere—which acts as a
blanket, trapping heat and
warming the planet. As we
burn fossil fuels like coal, oil
and natural gas for energy or
cut down and burn forests to
create pastures and
plantations, carbon
accumulates and overloads
our atmosphere. Certain
waste management and
agricultural practices
aggravate the problem by
releasing other potent global
warming gases, such as
methane and nitrous oxide.

breakdown of heat-trapping
4. FACTS ABOUT GLOBAL WARMING
The concentration of
carbon dioxide has
increased an average of
about 1.8 ppm per year
over the past two decades.
According to NASA, the
ten warmest years of
record have occurred in
the past fifteen-year period
(1998-2013).
About 75% of the annual
increase in atmospheric
carbon dioxide is due to
the burning of fossil
fuelslobal Warming
6. CONSEQUENCES
. Changes resulting
from global warming
may include rising sea
levels due to the
melting of the polar ice
caps, as well as an
increase in occurrence
and severity of storms
and other severe
weather events.
7. GREEN HOUSE EFFECT
The Consequences of
Global Warming
As the concentration of
greenhouse gases
grows, more heat is trapped
in the atmosphere and less
escapes back into space.
This increase in trapped heat
changes the climate and
alters weather
patterns, which may hasten
species extinction, influence
the length of seasons, cause
coastal flooding, and lead to
more frequent and severe
storms.
8. WHY YOU NEED TO ACT NOW
Substantial scientific evidence
indicates that an increase in the
global average temperature of
more than 2°F above where we
are today poses severe risks to
natural systems and human
health and well-being. To avoid
this level of warming, the U.S.
needs to reduce heat-trapping
emissions by at least 80 percent
below 2000 levels by 2050.
Delay in taking such action will
require much sharper cuts later,
which would likely be more
difficult and costly.
