What is Global Warming and Climate
Change?
Global Warming- Human activity like increased use of fossil
fuels and changes in farming have caused levels of Co2
and Methane to rise, and this in turn has resulted in an
increase in the average surface temperature of the Earth.
This increase is known as Global Warming.
Climate Change- Changes in weather patterns due to
global warming is called climate change. It is a long-term
change in the average weather conditions of a place or the
planet as a whole. It can refer to conditions becoming
warmer, wetter, or drier over several decades or more.
Greenhouse Gases
Gas that absorbs thermal energy reflected of the Earth,
stopping it from escaping the atmosphere. Carbon Dioxide
and methane are the biggest greenhouse gases that
contribute to climate change.
India is the world's third-largest emitter of greenhouse
gases (GHGs), after China and the U.S.. In 2021, India
emitted 3.9 billion metric tons of carbon dioxide equivalent
(GtCO₂e), accounting for roughly seven percent of the
global total.
Release of Carbon dioxide (CO₂) into the
atmosphere.
Carbon dioxide is produced during the complete
combustion of fossil fuels. Fossil fuels are used to produce
electricity and all the bases of many forms of transport. It’s
a greenhouse gas, able to trap heat and subsequently
contribute to global warming and climate change.
Methane, natural gas produces CO₂ when burned in a
plentiful supply of oxygen.
India is the third-largest emitter of CO₂ in the world India's
carbon emissions are expected to increase by 8.2% in
2023. This is more than double the expected increase in
China
Release of Methane (CH₄) into the
atmosphere
Methane is a potent greenhouse gas, twenty-five times
more effective at trapping heat compared with CO₂.
Reasons for rising levels of Methane in the atmosphere Increase cattle farming and more waste being generated by
larger populations.
Cattle emit a large amount of meeting as a part of the
digestive system.
Decomposition of food waste by bacteria landfill sites.
India is the second-largest emitter of CH₄ in the world. CH₄
emissions in India have increased more than 30 percent
since 1990. These emissions result from the agricultural
activities of farmers across India.
Reducing the amount of CO₂ released
into the atmosphere
Switch to the use of renewable sources of energy such as
wind and solar, for electricity generation.
Shift to using electric cars or hydrogen fuel cells over diesel
or petrol engines.
Use public transport.
Afforestation, and planting more trees so that the plants
capture of the CO₂ during photosynthesis.
It is also possible to capture CO₂ before it is released into
the oxygen and then storage underground.
Reducing the amount of Methane
released in the atmosphere
Educate people more about the harmful effects of an
excessively meat rich diet.
Better separation of household waste.
Methane produced at landfill sites can be trapped in burned
as a source of electricity and heat.
