This document discusses climate change, its causes, effects, and prevention. It states that climate change is caused by both natural factors like volcanic eruptions, solar activity, and ocean currents, as well as human-induced factors like deforestation, burning fossil fuels, industrialization, and greenhouse gas emissions. Some effects of climate change mentioned are shifts in rainfall patterns in India, increased temperatures damaging agriculture, and forced migration. Prevention methods discussed include using plants to reduce indoor air pollution and transitioning to more energy-efficient appliances and renewable energy sources.

3. DEFINITION
 Climate change refers to the change in the average
weather conditions.
 It lasts for an extended period of time.

5. CLIMATE CHANGE IS CAUSED BY
 Natural Factors
 Volcanic Eruption
 Solar Activity
 Orbital Changes
 Ocean Current
 Anthropogenic Factors/
Human Causes
 Deforestation
 Coal Mining
 Burning of Fossil Fuels
 Industrialization
 High Population
 Green House Gases

8. VOLCANIC ERUPTION
 Volcanoes release the greenhouse gas carbon
dioxide, contributing to warming of the atmosphere.
But the effect is very small. Emissions
from volcanoes since 1750 are thought to be at
least 100 times smaller than those from fossil fuel
burning.

10. OCEAN CURRENTS
 Ocean currents act like a conveyor belt,
transporting warm water and precipitation from the
equator towards the poles and cold water from the
poles back to the tropics.

12. ORBITAL CHANGES
 Earth’s orbit around the sun is due to the
gravitational attraction between the earth and the
sun. It follows an elliptical path.
 Currently the earth is closest to the sun in the
Northern Hemisphere. However the earth’s tilt of its
rotational axis causes bigger changes in incoming
sunlight and so it has a bigger effect on the
seasons.

14. SOLAR VARIATIONS
 It has been suggested that changes in the solar
output might affect our climate both directly, by
changing the rate of solar heating of the Earth and
Atmosphere and indirectly by changing the cloud
forming process.

17. COAL MINING
 The EIA (Environmental Impact Assessment)
estimated that coal mining was responsible for the
10% of the total methane production.
 Since methane is one of the greenhouse gases it
may lead to global warming.

19. HOW DOES FOSSIL FUELS INFLUENCE
CLIMATE?
 When fossil fuels are burned, they release carbon
dioxide and other greenhouse gases, which in turn
trap heat in our atmosphere, making them the
primary contributors to global warming
and climate change.

21. HOW DO PLASTICS INFLUENCE CLIMATE
CHANGE?
 Sunlight and heat cause the plastics to release
powerful greenhouse gases, leading to an alarming
feedback loop. As our climate changes, the planet
gets hotter, the plastics break down into more
methane and ethylene, increasing the rate
of climate change, and so perpetuating the cycle.

24. HOW DOES DEFORESTATION INFLUENCE
CLIMATE CHANGE?
 Burning or cutting down trees reverses the effects
of carbon sequestration and releases greenhouse
gases (including carbon dioxide) into the
atmosphere.

47. CLIMATE CHANGE IN INDIA
 Majuli, the largest riverine island in the
Brahmaputra River. Majuli has a very high poverty
rate at around 21.47% (according to Jorhat District
administration). Climate change has resulted in
continuous shifts in rainfall pattern as well as an
increase in temperatures of the island. It has also
lost visibly large tracts of land due to erosion over
the last century. The already low income of island's
population is further declining due to lower farm
productivity caused by frequent floods, erosion, and
siltation. The loss of livelihood due to climate
induced events has resulted in forced migration to
neighbouring urban centres such as Jorhat.

49. CLIMATE CHANGE IN INDIA
 As climate change becomes more palpable, some
parts of India will be more affected. Comparing the
average temperature in 2009-18 to the that in 1950-
80 reveals that some pockets have already become
much hotter. In parts of Rajasthan, Gujarat, Tamil
Nadu, Kerala and the North-East, average
temperature over the last decade has risen by
nearly 1° C compared to the historical average in
the 1950-80 period.

50. CLIMATE CHANGE IN INDIA
 A region’s vulnerability to temperature changes
depends on several factors such as access to
infrastructure (electricity, roads and water
connections) and dependence on agriculture.
According to the World Bank, central districts in
India are the most vulnerable to climate change
because they lack the infrastructure and are largely
agrarian. Within this region, the districts in
Maharasthra’s Vidarbha region are particularly
susceptible to climate change damage.

70. INDIAN YOUTH CLIMATE NETWORK (IYCN)
 India has one of the largest youth populations in the
world, about two-thirds of its population is under the
age of 35. For meaningful long-term change to take
place, conversations on climate change must
include youth voices. That is why the EDF
(Environmental Defense Fund) worked with
talented young leaders to set up the Indian Youth
Climate Network (IYCN) which is India's largest
youth network on climate change and has local
chapters across the country.
