Climate Change is alarming time in
modern days. Due to environmental
pollution climate whole world to
alarming change. Poor and developing
country are now blaming industrially
developed. Increase the burning fossil
fuel has been responsible the rise of
temperature. Ice caps melting. Hence a
coastal area going through under water.
The planet’s climate has constantly been
changing over geological time, with
significant fluctuations of global average
temperatures. However, this current
period of warming is occurring more
rapidly than any past events. It has
become clear that humanity has caused
most of the last century’s warming by
releasing heat- trapping gases commonly
referred to as greenhouse gases to power
our modern lives. We are doing this
through burning fossil fuels, agriculture
and land-use and other activities that
drive climate change. Greenhouse gases
are at the highest levels they have ever
been over the last 800,000 years. This
rapid rise is a problem because it’s
changing our climate at a rate that is too
fast for living things to adapt to. Climate
change involves not only rising
temperatures, but also extreme weather
events, rising sea levels, shifting wildlife
populations and habitats, and a range of
other impacts.
2. What Is Climate Change?
Climate change is a variation or change
in the climate (temperature, wind,
precipitation patterns) in a specific
location, region, or of the entire planet.
This change in weather patterns persists
for a long period of time ranging from
decades to millions of years. Climate
change may be caused by a variety of
factors including natural processes;
however, scientific evidence shows that
the current period of climate change is
caused by human activities.
Earth Orbital Changes: A slight change in
the tilt of the earth can lead to climatic
changes. While less tilt means cooler
summers and milder winters; more tilt
means warmer summers and colder
winters. These small and slow changes
can lead to important changes in the
strength of the seasons over tens of
thousands of years.
Man-Made Factors –
The Greenhouse Effect: When sunlight
reaches Earth’s surface, it can either be
reflected back
Into space or absorbed by Earth. Once
absorbed, the planet releases some of the
energy back into the atmosphere as heat
(also called infrared radiation).
Greenhouse gases like water vapor
(H2O), carbon dioxide (CO2), and
methane (CH4) absorb energy, slowing
or preventing the loss of heat to space. In
this way, GHGs act like a blanket,
making Earth warmer than it would
otherwise be. This process is commonly
known as the “greenhouse effect.”
Gases that Play a Part in Climate
Change: Carbon dioxide also plays an
important role, even though it is one of
the more minor components in our
atmosphere. It can be found through a
variety of different processes, including
respiration, volcanic activity,
deforestation, fossil fuel burning, and
others. The carbon dioxide that is found
in our atmosphere continues to increase,
making the climate change much more
prominent these days than before. CFCs,
or chlorofluorocarbons, which are
basically synthetic compounds that are
created in the industrial setting, also play
a part. They are usually what plays a part
in the depletion of the ozone layer. The
more the ozone layer is depleted, the
hotter our earth will get. Nitrous oxide iş
another type of gas that is often times
formulated from the soil when it is
cultivated. It is one of the other gases that
has an impact on our climate change.
4. Effects of Climate Changes?
Climate change can really have a lot of
negative consequences. It is important to
do something about it to help decrease
the amount of change that occurs and
make it not happen so fast.
High Temperatures and Heat Waves: The
continuous increases of greenhouses
gases in the atmosphere has caused
temperature to rise which is called as
greenhouse effect. Though greenhouse
effect is necessary for survival of all of
us on this planet but increase of these
gases beyond a limit will only create
harmful effects for us and this
environment. During last century, earth's
average temperature rose by 1 degree
Fahrenheit which in itself is a cause of
concern. The large amount of greenhouse
gases released from industries, vehicles,
agricultural activities increases the
concentration of CO2 and heats up the
atmosphere. The increased temperature
then cause heat waves and makes it
difficult for people to survive.
Change in Rainfall Patterns: In last
couple of decades, excess rainfall,
droughts, hurricanes and floods have
become quite frequent. While few areas
experience plenty of rainfall, then there
are areas that face droughts throughout
the year.
