What do you know about
climate change?
Climate change refers to the changes in temperature,
precipitation, or wind patterns, among other effects,
that occur over several decades or longer.
Does climate change exist?
• Research by different groups of scientists indicate that
climate change is occurring.
• Many websites, articles, and textbooks have clear evidence
to prove the existence of the phenomenon.
Scientists have conducted research
on the following:
• Changes in heights of physical environmental aspects, for
example the ice-caped mountains.
• Increased rate of disasters in various parts of the world.
• Increased water levels in the seas and oceans threatens the
people who live on coastlines.
Impacts created by increasing temperature
EPA and NASA did a study on increasing temperatures. The change in
temperature of about 1.4 degrees (F) for the past century has caused the
melting of the glaciers (ice) in many parts of the world.
Water Crisis in the West
• Climate change has led to increased violence among farmers,
housing developers, and the environmentalists.
• Farmers and urbanites put blame on each other for water
misuse.
• Environmentalists are against the poor water management
skills among the U.S. citizens (12/09/2011).
Coastal settlements are no
longer desirable.
• Research done by EPA indicates a 7 inch increase in the trend
of sea level waters in the United States of America during the
20th century.
• Scientists anticipate an increase of about 29 to 30 inches at
the end of the century. This threatens people at the
coastline.
• Residents of Louisiana and other coastal areas are first the
victims of the catastrophe.
