Why Earth Is Becoming Warmer?
As we all noticed recently, the temperature
of our planet is getting higher and higher, which makes our lives harder to
handle economically and socially. However, what is the main cause behind this
significant change in temperature? Global warming is a major problem that
started to threaten every creature on earth starting from the ones in the deep
oceans up to us as human beings living on the surface. The points that I will
focus on during explaining this phenomenon are the definition of global
warming, the harmful effects of this phenomenon, and the solutions that can lower
these effects.
Global warming is
a phenomenon that can briefly be defined as a significant increase in
temperature in the atmosphere around the earth. This increase is occurred under
some specific conditions; for example, the burning of fossil fuels in cars is a
main cause of global warming. This is due to the huge amounts of carbon dioxide
CO2 released from this procedure. The carbon dioxide travels through
the layers of atmosphere until it reaches the ozone layer, which in turn
contains a high concentration of ozone O3. The role of this layer is
to absorb the harmful lights coming from the sun and prevent it from reaching
the organisms. However, the high release of CO2 results in an
increase in the concentration of it in the atmosphere. This increase of CO2
affects the ozone layer negatively and causes what we call the ozone hole. As
mentioned earlier, the main role that the ozone layer plays is absorbing the
harmful light coming from the sun, but what if there is a hole in this layer?
The ozone hole permits these lights to infiltrate to the earth but prevent them
from returning to the outer space. The greenhouse gases in the atmosphere
absorb some of the long wave lights, which causes the warmth of the atmosphere.
Therefore, these harmful lights and other gases are locked up in the domestic
air layers of the earth and are reflected to cause global warming.
The harmful
effects of global warming are numerous, and most of them are taking place in
our daily lives. Initially, let’s talk about the effects of this phenomenon on
the oceans. The rise of temperature leads to the melting of ice in the Arctic
and the Antarctic. This melting leads, in turn, to the rise of the sea level
and causes floods, in addition to droughts and some other damages. Moreover, global
warming usually affects the hydrological cycle of evaporation and causes
precipitation, and this latter is represented in many forms. Acid rain is a
common form of precipitation, and the occurrence of this natural disaster is
usually attributed to the release of carbon dioxide and some other gases, which
react with water particles and cause the fall of acidic rain. To be more
specific, as the concentration of carbon dioxide increases, the chance of
having acid synthesis reaction increases too. The consequences of this problem
appear in the harm it causes to the plants and the animals, especially the
aquatic ones. The soil is damaged because the acidic rain causes the killing of
many microbes and organisms living in the soil and helping the growth of
plants; therefore, plants are extremely damaged, economically speaking,
agricultural crops are negatively affected. On the other extreme, the harm that
is related to the aquatic animals is attributed to the increase in the concentration
of aluminum and the decrease of the pH scale in the water surface.
Based on all what
was mentioned about the causes and the effects of the global warming, we can
conclude that the main reasons behind this phenomenon are the human activities.
Thus, people should stop being selfish, start thinking about the social
interest, and try to find some effective solutions to diminish the damages
caused by the change in the climate. Using other natural resources of energy is
an aspect, or solution, that government started to apply recently. For
instance, using biofuel and nuclear power instead of fossil fuel is already a
good start toward a cleaner and a healthier future. In addition, using new
technology to filter the gases generated from the combustion of fossil fuel and
recycling the factory waste will be a great step to decrease the emission of CO2
and many other harmful gases.
Finally, and
according to Barack Obama:
All across the world, in every kind of
environment and region known to man, increasingly dangerous weather patterns
and devastating storms are abruptly putting an end to the long-running debate
over whether or not climate change is real. Not only is it real, it's here, and
its effects are giving rise to a frighteningly new global phenomenon: the
man-made natural disaster. (“Notable Quotes”)
Global warming, as a phenomenon that indicates an increase in the
temperature of the atmosphere around the earth, has started to reach paroxysm.
Its harmful effects were not satisfied by only damaging the environment, but
they are also willing to destroy the health of all the organisms. The solutions
are in our hands, and as we caused the existence of this phenomenon by our
activities, we have to be responsible to apply these solutions effectively and
to do our best to protect ourselves from ourselves.
