GLOBAL WARMING
Global warming is a huge environmental and economic challenge that we
are facing in the 21st century. Global warming is also commonly
referred to as the greenhouse effect. Global warming can affect entire
ecosystems and climates, which in turn affect the way in which people
live. We in our lifetimes will not be around to see the major outcome
of global warming; however, it is still a major concern. It has come to
be known that the major increase in temperature over the last century
is a result of the Industrial Revolution. During the Industrial
Revolution, when new machines were being used, there were major
increases in carbon dioxide levels in the atmosphere, which is one of
the main causes of the greenhouse effect. This is the main reason that
scientists believe the temperature increase is the effect of humans
rather than a climate change.
Over the course of the past century, the Earth’s global temperature has
risen by about one degree Fahrenheit. This may not seem like a large
increase, but given the time period in which this increase occurred, the
change is quite amazing. Some scientists argue that this one-degree
increase is just the Earth’s natural changing climate, but others
believe that it is due to global warming. More and more scientists are
becoming convinced of global warming and its dangers. Global warming is a
phenomenon that occurs when fossil fuels are burned and greenhouse
gasses are ejected into the atmosphere and burn ozone; the shield that
reflects ultra violet rays from the sun. Global warming doesn’t just
affect the temperature; it also affects all aspects of climate and
weather.
The most common belief of global warming is that the temperature
increase is in direct variation with the increase of carbon dioxide in
the atmosphere. The affects of global warming will develop slowly over a
long period of time.
