Global Warming

Global Warming refers to the observed increase in the average temperature of the earth’s oceans and atmosphere.

Science reveals that the earth’s near surface atmospheric temperature has risen approximately 0.6° Celsius, (1.1° Fahrenheit) over the course of the 20th century. No one knows exactly why this increase has occurred, but it is widely believed that human activity is the probable cause.

Broad segments of the science community assert that human production of greenhouse gases are a primary agent of recent warming. Anthropomorphic greenhouse gases are produced by the burning of fossil fuels and they contribute to phenomena called the Greenhouse Effect.

There is a tremendous amount of debate surrounding the issue of global warming because of its potential costs and effects on the environment and human life. These include, but are not limited to: glacial melting, a rise in the earth’s sea level, population displacement, destabilization of ocean currents, adverse effects on agriculture, reductions in the o-zone layer, increases in the frequency and intensity of extreme weather events and an increase in the spread of infectious disease.
