Essay On Climate Change
Introduction: Climate change
is now widely recognized as the major environmental problem facing the globe.
It has now become a major concern for people throughout the world. The use
of fossil fuels to meet the energy of the world contributes to an increase in
greenhouse gases mainly carbon-di-oxide and methane in the earth’s atmosphere.
Climatologists opine that this increase is leading to climate change with
adverse effects on the environment.
Causes
of climate change: Studies of long-time climate change have discovered a
connection between the concentration of carbon-di-oxide in the atmosphere and
global temperature. Carbon-di-oxide is one of the most important gases
responsible for the greenhouse effect. Over the past three centuries, the
concentration of carbon-di-oxide has been increasing in the atmosphere of the earth because of human influence. Human activities like burning fossil fuels,
conversion of natural prairie to farmland, and deforestation have caused the
release of carbon-di-oxide into the atmosphere. Besides, some other factors are
primarily responsible for climate change on the earth like as: variations in
the earth's orbital characteristics, volcanic eruptions, and variations in solar
output.
Impact:
Although
industrial countries are responsible for the accumulation of greenhouse gas
emissions, the effects of global warming are most severe in the poorest
countries. It is said that the poorest who are not responsible for carbon emissions
into the atmosphere, will be the worst hit by the devastation of climate
change.
Scientists have identified some threats
that people throughout the world will have to face. The threats are Rapid
change in global warming, rising sea levels, increasing ocean acidification,
increased insects and diseases, and failing agricultural output, agriculture, and
livelihoods are already being affected.
Threats
to Bangladesh: Bangladesh being a developing country become one of the
hardest hits of climate change. She is under constant threat of climate change.
According to the observation of the IPCC, the average temperature of Bangladesh
has increased from 0.2 to 1 degree Celsius every year. The probable threats
that Bangladesh may face due to climate change are: an increase in Natural
disasters, the rise of sea level and coastal areas and low lands will go under
water, desertification of dry areas, agricultural production will be decreased, and fishery and forests will be destroyed.
Measures
to be taken: Climate change has attracted a lot of attention in
recent years as The UN Secretary-General Ban-Ki-Moon in his stressed the need
for international efforts to fight, mitigate and adapt to the problem of global
warming in his speech at the MDG meeting. To mitigate the threats of climate change
some immediate steps should be taken, reduce greenhouse gas and create
solutions to protect the environment, reduce emissions of carbon-di-oxide and
improve efficiency, protect the tropical forest, stop the use of fire woods and
bio-fuels, expand the programs of planting trees, especially in the coastal
areas, increase public awareness about protecting the environment.
Conclusion:
Climate
change impacts everyone regardless of national borders. It does not bother
whether it is a developing country or not. The leaders of the world should
agree on a road map to tackle the issue of overcoming all the differences among
them.
