Global
warming is the observed rise in climate system and its after effects. The main
cause of global warming is the effect of green house gases such as carbon
dioxide. Emissions from burning fossils also add to the increase of temperature.
Earth's climate is influenced by the atmosphere which is in the first six miles
or so. It contains the matters that creates atmosphere. Global warming not only
increases the heat but leads to many natural calamities like melting of
glaciers which will increase the sea level, ocean acidification, droughts,
heavy rainfall etc.
The
greenhouse effect is the course of action of emission and absorption of
infrared radiation by gas elements in a planet's atmosphere warm its lower
atmosphere and surface. Human activities after industrial revolution increased
the emission of greenhouse gases to the atmosphere. Deforestation as a part of
'revolutions' also contributed for making the climate instable. Emissions from
industrial and household machineries kill the ozone layer in a slow and steady
manner. It is after many years, after the increase in the climate changes that
we observed it.
The
impacts of global warming are not easy to digest. Its hands are too wider than
we can imagine. Rising sea level is one of the impacts of global warming. As we
know very well, 71% of earth's surface is water. If sea level increases, we
will have to change this ratio and live in more congested area. The temperature
that grows high makes glaciers in arctic area melt and it causes the increase
of sea level. Global warming also affects the rainfall pattern. Unexpected
flood or droughts would ruin the lives of all creatures in this planet.
Vanishing of animal population is another threat that global warming puts
forward. Insufficient resources and unpredictable climate changes will force
species to vanish from the surface. We, human being are not safe, it can happen
to us too. Outbreak of diseases is another crucial part of global warming. In a
situation that is not supportive for survival, diseases can easily spread out
and take lives with less effort.
The
above said impacts are for those living in land. The creatures living under
water also have to face serious effects of global warming. Excessive formation
of carbonic acids in the ocean can destroy the eco system under water.
Acidification makes water not usable for living. Those creatures which are
surviving by eating other creatures starve for food and may die. It is because
of the acidification which makes the marine food not eatable.
We
can control global warming by rising energy sufficiency, encouraging green
transportation, using renewable energy like solar power, bio-gas etc., reducing
fossil fuel electricity, managing forests and agriculture, developing
technology that avoids the use of carbon or eliminates carbon from every activity.
We
have technology, we know how to create things that we need, we can collect data
on anything on earth, it is a matter of understanding and commitment to lower
the impacts of global warming in coming years.
