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.
