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
