2.  Climate change, also called global warming, refers to
the rise in average surface temperatures on Earth
 Climate change is due primarily to the human use of
fossil fuels, which releases carbon dioxide and other
greenhouse gases into the air.
TCP PRESENTO 2020, THIAGARAJAR COLLEGE OF PRECEPTORS, MADURAI.

3.  Climate change refers to any significant change in the
measures of climate lasting for an extended period of
time
 Climate change includes major changes in temperature,
precipitation, or wind patterns, among other effects,
that occur over several decades or longer.
 Climatic Change is caused due to global warming , acid
rain , greenhouse effect etc .
TCP PRESENTO 2020, THIAGARAJAR COLLEGE OF PRECEPTORS, MADURAI.

4.  Global warming is the long-term heating of Earth’s
climate system observed since the pre-industrial period.
 It is caused due to human activities, primarily fossil
fuel burning, which increases heat-trapping greenhouse
gas levels in Earth’s atmosphere.

7.  Acid rain, or acid deposition, includes any form of
precipitation with acidic components, such as sulfuric
or nitric acid that fall to the ground from the
atmosphere in wet or dry forms.
 This can include rain, snow, fog, hail or even dust
that is acidic.

8.  Acid rain results when sulfur
dioxide (SO2) and nitrogen
oxides (NOX) are emitted into
the atmosphere and transported
by wind and air currents.
 SO2 and NOX react with water,
oxygen and other chemicals to
form sulfuric and nitric
acids. These then mix with
water and other materials before
falling to the ground.

9.  Burning of fossil fuels
 Vehicles and heavy equipment
 Manufacturing, oil refineries and other industries.

11.  The greenhouse effect is a process that occurs when gases
in Earth's atmosphere trap the Sun's heat.
 This process makes Earth much warmer than it would be
without an atmosphere.
 Radiative active gases(i.e., greenhouse gases) in a planet's
atmosphere radiate energy in all directions .

12.  Carbon dioxide (CO2)
 Methane (CH4)
 Nitrous oxide (N2O)
 Ozone(O3)
 F – Gases (Chlorofluorocarbons
(CFCs), hydro chlorofluorocarbons (HCFCs), hydro
fluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur
hexafluoride (SF6))

15.  Changes in sun’s energy and slow changes in earth’s orbit
 Change in ocean circulation
 Human Activities - Burning of fossil fuels, deforestation,
usage of gases, development of buildings in cities
 Global Warming
 Greenhouse gases

17.  Extreme weather events
 Dirty air
 Health risks
 Melting glaciers , Rising seas
 Ocean acidification
 Imperiled ecosystems
 Frost-free Season (and Growing Season) will lengthen
 Changes in Precipitation Patterns
 Natural calamities – earthquakes, flood, drought, cyclones
 Hazardous Diseases – cancer from radiations , incurable
allergies
 Wildfires

23.  Power your home with solar or wind is still one of the best
ways to fight climate change
 Lower greenhouse gas emissions by eating less meat,
choosing local foods when possible and buying food with less
packaging
 Saving water
 Choose a fuel efficient vehicle when purchasing, take public
transportation if it’s available, carpool to work, ride a bicycle or
walk when possible. These are all ways to reduce the amount
of greenhouse gases entering the atmosphere and heating
our planet
 Recycling. Re-using materials usually uses less energy, and
thus creates less pollution, than extracting raw materials.
 Plant trees, to help suck carbon out of the air and stabilize the
climate .

25. Summarizing the climatic change, it is mainly
caused due to Global Warming , Acid Rain and Green
house effect. Each cause affects the earth in its own way
leading to a threatening life for every creature. Thus, by
following the solutions mentioned to overcome the above
hazards, we can make earth a healthier place to live. It is
not easy to heal the earth sooner or later, but we, together,
holding hands, following at least one of those remedies,
can cure it to a place way better than now. Don’t wait for the
change to happen. Take a step ahead and make the change
yourself. Help the creatures to survive in this planet. Make
the mother earth, a better place to live.
