3. What is Global Warming?
Global warming is the long-term increase in Earth's average
surface temperature due to human activities, such as burning
fossil fuels and deforestation, which release greenhouse
gases into the atmosphere. These gases trap heat,
intensifying the natural greenhouse effect and causing rising
temperatures, melting ice caps, sea-level rise, extreme
weather events, and ecosystem disruptions. It poses
significant threats to human health, agriculture, economies,
and the environment. Mitigation efforts focus on reducing
greenhouse gas emissions, while adaptation strategies
address the impacts already occurring.
4. The Primary Causes
of global warming
Human Causes Natural Causes
Greenhouse Gas Emissions Volcanic Activities
Industrial Processes Orbital Variations
Deforestation Solar Variability
The burning of fossil fuels releases
significant amounts of greenhouse gases
into the atmosphere. These gases trap
heat enhanced greenhouse effect, leading
to global warming.
Volcanic eruptions release large amounts of
ash and sulphur dioxide into the atmosphere,
which can temporarily cool the planet by
Certain industrial activities release
greenhouse gases, such as methane
(CH4) and nitrous oxide (N2O), which are
potent contributors to global warming.
Changes in Earth's orbit and axial tilt can
affect the distribution of solar radiation on
Earth, leading to periods of warming or
cooling over geological timescales.
The cutting down of forests reduces the
planet's capacity to absorb CO2, as trees
play a crucial role in carbon sequestration.
When forests are removed, the stored
carbon is released into the atmosphere,
adding to greenhouse gas concentrations.
Changes in the sun's output of energy can
influence Earth's climate over long periods.
However, solar variations are relatively
small compared to the influence of human-
caused greenhouse gas emissions.
5. Global warming
Average global temperatures are increasing, leading to more frequent and prolonged
Glaciers and polar ice caps are melting, contributing to rising sea levels.
Changes in temperature and weather patterns impact ecosystems, leading to shifts in
animal habitats and migration patterns.
Global warming can lead to heat-related illnesses, the spread of diseases, and worsened
air quality, impacting human health.
Global warming can threaten the survival of many species as they struggle to adapt to
changing conditions or face habitat loss.
7. Framework Convention on Climate
The Paris Agreement is a landmark international
accord aimed at limiting global warming to well below 2
degrees Celsius above pre-industrial levels, with
efforts to limit the increase to 1.5 degrees Celsius, by
collectively reducing greenhouse gas emissions.
It is an international treaty aimed at addressing
global warming by fostering cooperation among
nations to reduce greenhouse gas emissions and
combat climate change.
8. Individuals play a vital role in addressing global warming through various actions and
choices they make in their daily lives. Here are some key roles individuals can play:

Roles of Individuals
The evidence is clear: our planet is
experiencing rising temperatures, and the
consequences of this phenomenon are
becoming increasingly evident.
By reducing greenhouse gas emissions,
transitioning to renewable energy
sources, and adopting sustainable
practices, we can work towards a
more resilient and sustainable future
for ourselves and future generations.
2020 was recorded as one of the warmest
years ever recorded, with global temperatures
surpassing the previous record set in 2016
These warming trends are not isolated incidents;
they are accompanied by a host of concerning
effects, including melting ice caps, sea-level rise,
extreme weather events, and disruptions to
However, it's not all doom and gloom.
Together, as individuals, communities,
and nations, we have the power to
mitigate the impacts of global warming.
