Global Warming

Global Warming, aside from pollution is one of scientists biggest

concerns. Global Warming is caused by the Greenhouse effect.

There are 4 steps in the Greenhouse effect. 1-Sunlight radiates

from the sun, through space, to EarthÆs atmosphere. 2- The

sunlight enters the atmosphere and hits Earth. Some of it turns

into heat energy in the form of infrared light. The heat gets

absorbed by surrounding air and land, which in turn makes it

warm. 3- Infrared rays, that are remitted into the atmosphere are

trapped by greenhouse gases. 4- The gas then absorbs the light

and is remitted back to the EarthÆs surface and warms it even

more. Some of the naturally occurring greenhouse gases are

Methane and carbon dioxide. This is the way the Earth keeps

itself warm enough for humans to live on it.

The only problem with this is that humans enhance the process

even more. Over the past 200 years the emissions of greenhouse

gases have been increasing due to the increase in technology that

humans have developed (example, factories). These human-induced

gases include carbon dioxide, methane, nitrous oxide, and ozone

depleting substances such as CFCs, also known as

Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons.

These gases are generated a number of human activities

such as fossil fuel combustion, waste disposal in landfills, the

use of a refrigerator, numerous agricultural and industrial

activities, and the cutting down of numerous forests.

These human practices have already changed the chemical make up

of the atmosphere. Between the pre-industrial times and today, we

have seen the concentration of carbon dioxide rise 30% in some

regions, in particular the northern hemisphere, human practices

have increased concentrations of aerosols in atmosphere, which is

a traditional form of air pollution), which tends to cool the

atmosphere.

With all these gases in the air, it is starting to change the

EarthÆs climate. The temperature of the EarthÆs surface is as

warm, if not warmer than it has been in any other century since

at least 1400 AD. The temperature over the past century has risen

one degree Fahrenheit over the last century. These last few

decades have been the warmest this century. The sea level has

risen 4 to 10 inches, and mountain glaciers world-wide have begun

to retreat.

It is important to recognize that with the recent warming and the
