Global Warming
Introduction
Today’s world, the burning issue is “Global warming” is resulted in Global problem. The
global warming which causing an alarm among the mankind, is being increased day-by-day. The
global warming is being increased due to Selfishness and greediness of human beings which
resulted in Pollution of environment. The Greenhouse effect of global warming and depletion of
ozone layer is the major problems , ozone is a colorless gas in ozone layer and it is a allotropy of
oxygen and has three atoms as compared to O2 which has 2 atoms. Under the influence of uv
radiation from sun in the upper atmosphere layers, ozone is produced by recombination of
oxygen. It occurs 16 km above earth’s surface and found in the stratosphere and extends from 12
km to 35 km.
The world’s biggest problem facing the world today is global warming. Our production
of other greenhouse gases and carbon dioxide is heating the atmosphere, and this could be very
dangerous for human life. The biggest problem is rising sea level which result in the flooding of
low lying coastal areas and cities, such as the Netherlands, Bangladesh and Egypt.
The biggest problems is raising sea level and result in the flooding of low lying coastal
areas and cities, such as Egypt, the Netherlands, and Bangladesh. Global warming is changes in
weather patterns. Global warming is the effect on animals. Fish populations could be affected, so
the solution is to stop producing C02 and can be done by switching from coal, oil and gas to
renewable energy and also to plant more trees. Trees produce oxygen, and absorb carbon dioxide
and is not a greenhouse gas and to use less energy and to recycle more products. To use less
electricity, to produce less CO2

CO2 emission is another problem and by the increase of greenhouse gases, carbon dioxide
accounts for more than 60 percent of the enhanced greenhouse effect and by more than 10
percent every 20 years, the carbon dioxide level in the atmosphere is increasing. If emissions of
carbon dioxide continue to grow at current rates, then the gas level in the atmosphere double, or
triple, from levels of pre-industrial during the 21st century.
Coal is a compost primarily of carbon along with variable quantities of other elements chiefly
sulphur, hydrogen, oxygen and nitrogen. Coal is a fossil fuel and is the largest surce of energy
for the generation of electricity world wide and well as one of the large worldwide sources of
CO2 emission. Gross CO2 emission from coal usage is high and more than that from petroleum
and about double the amount from natural gas. Coal is obtained through mining or from open
pits. Coal is primarily used as a solid fuel to produce electricity and heat through combustion.
When coal is heated in air, coal urns and produces mainly carbon dioxide gas. Coal is processed
in industries to obtain some useful products such as coke, coal tar and coal gas. Next, the
changes in weather patterns. Many areas of the world are experiencing increased floods, other
natural disasters and hurricanes. While some insects which spread disease might become more
common and a final issue is the negative effect on animals that is the fish populations could be
effected. To deal with global warming is to stop making carbondioxide CO2 that is by switching
from coal, oil, and gas to renewable energy. To plant more trees, that os trees produce oxygen
and absorb CO2 and, which is not a greenhouse gas.
To use less energy and more products recycle, use less energy and are more environmentally
friendly, the temperature of the earth may not rise too much. Climate change is impact the
characteristics of tropical cyclones that is the strongest as “hurricanes” in the Atlantic ocean. To
increase the maximum possible intensity, Warming tropical ocean temperatures associated with
global and thus the destructive potential, of tropical cyclones.
A close relationship is between warming ocean temperatures in recent decades and the increased
powerfulness of hurricanes, in the Atlantic, where long-term data are available.
Environmental effects of coal burning
Generation of waste products which contain mercury, uranium, thorium, arsenic and other heavy
metals which are harmful to human health and environment, Sulphur particles present in the coal
causes acid rain, Interference with ground water and water table levels. Contamination of land
and water bodies, Dust pollution. Release of CO2, a greenhouse gas, causing climate change and
global warming. Coal is the largest contributor to the man made...
