Global warming is caused by increased levels of greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere. This enhanced greenhouse effect has led to rising global temperatures. Some key impacts are rising sea levels as ice caps melt and more extreme weather events. To address this, India has undertaken initiatives like investing in renewable energy and energy efficiency programs, as well as creating public awareness campaigns about sustainable practices. Overall global warming poses a major threat to the environment and climate if greenhouse gas emissions continue unchecked.

2. WHAT IS GLOBAL WARMING ?
 Global Warming is the increase of Earth's average surface temperature due to
effect of greenhouse gases, such as carbon dioxide emissions from burning fossil
fuels or from deforestation, which trap heat that would otherwise escape from
Earth. This is a type of greenhouse effect.

4. WHAT IS GREENHOUSE EFFECT ?

5. The sun sends out energy as
heat and light. This energy
comes to our earth during the
day time.
Some of the sun’s rays get ‘trapped’
in the atmosphere.
Some of them get reflected back
into space.
The ones which get through the
atmosphere warm the earth up.

6. All the time, the earth
radiates heat into space,
which cools it down. We
only really notice this at
night, when there is no
heating from the sun.
Some of the heat going out is
trapped by the atmosphere. This
is what makes our planet warm
enough to live on.
But if too much heat is trapped,
our planet will warm up and
the climate will change.

8. GREENHOUSE GASES
 Carbon dioxide
 combustion of solid waste, fossil fuels (oil, natural gas, and coal), and wood and
wood products
 Methane :
 production and transport of coal, natural gas, and oil. Methane emissions also result
from the decomposition of organic wastes in municipal solid waste landfills, and
the raising of livestock.
 Nitrous oxide
 agricultural and industrial activities, as well as during combustion of solid waste
and fossil fuels.
 hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur
hexafluoride (SF6),
 industrial processes.

10. IS GREENHOUSE EFFECT BAD ?

11. Natural
Greenhouse
effect
More heat is
trapped and
causes global
warming
Atmosphere traps
some heat
Some heat
goes out to
space
Quite a lot of heat
is trapped and the
earth is warm
enough for life.
Enhanced
Greenhouse
effect
Heat radiates
from the earth
Heat radiates

Atmosphere traps
more heat
Less heat
goes out
