Climate
change is a significant and
lasting change in the statistical distribution of weather patterns over periods
ranging from decades to millions of years. It may be a change in average
weather conditions, or in the distribution of weather around the average
conditions. Climate change is caused
by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as
significant causes of recent climate change, often referred to as "global warming.
The world now faces
one of the most complex and important issues it has ever had to deal with:
climate change. Though this was once an issue that would draw much
argument and strife about its creditability, most of the world’s nations can no
longer deny that it is a real issue. The impact that humans have had on
the world has literally changed the climate. Higher temperatures are
reported yearly, stronger storms are forming, and some of the planet’s critical
nonrenewable resources are being depleted. For all of these changes that,
in the end, affect everyone, the nations of the world have not all gone about
this issue in the same way. Currently, the threat of global climate
change does not threaten some to the same extent of others. The
shortsightedness of those that are not yet drastically effected is one of the
most serious issues that the world deals with now and fundamental changes must
be made to advert a global crisis that everyone may face if no actions are
taken.
More people exploit more natural
resources, cut more trees, use more fossil fuels, produce more wastes, build
more roads, dams and cities, pollute more soil, water and air, and contribute
more greenhouse gases to the atmosphere ' which may lead to the ozone depletion
and global warming, ultimately damaging the entire environment and aggravating
the climatic change.
Thus,
man is capable of influencing global climate deliberately or inadvertently
through his various actions and activities.
