2. Climate change

3. TOPIC
• Introduction to climate change
• Causes of climate change
• Effects of climate change
• Solutions and actions

4. Understanding
Climate Change
• Climate change refers to long-term shifts in
global weather patterns, primarily driven by
human activities emitting greenhouse gases.
The burning of fossil fuels and deforestation
releases carbon dioxide and other pollutants,
trapping heat in the atmosphere and causing
Earth's average temperature to rise. This
warming leads to a range of environmental
impacts, including more frequent and severe
weather events, rising sea levels, and
disruptions to ecosystems. Urgent global
efforts are needed to mitigate climate change
by reducing emissions, transitioning to
sustainable practices, and adapting to the
evolving conditions to ensure a sustainable
and habitable future for the planet.

5. Impact of Climate
Change
• Rising global temperatures
• Increased frequency of extreme
weather events
• Risks to biodiversity and
ecosystems
• Threats to food and water
security
• Social and economic implications
• Measures for mitigation and
adaptation

6. Effect of Climate
Change
• Rising global temperatures: Climate change is causing a
steady increase in global temperatures, leading to
heatwaves, droughts, and wildfires.
• Melting ice caps and glaciers: The warming climate is
causing the rapid melting of ice caps and glaciers,
contributing to rising sea levels.
• Sea-level rise: As ice melts and ocean temperatures
increase, sea levels are rising, resulting in coastal
flooding and erosion.
• Extreme weather events: Climate change is intensifying
extreme weather events such as hurricanes, cyclones,
and heavy rainfall, leading to increased property
damage and loss of life.
• Changes in ecosystems and biodiversity: Climate change
is disrupting ecosystems and leading to the loss of
biodiversity, impacting plant and animal species.

7. Effect of Greenhouse
Gases
• Waste Management:
• Landfills and waste treatment processes can produce methane, a potent
greenhouse gas.
• Changes in Energy Use:
• The transition from traditional energy sources to more carbon-intensive
fossil fuels has increased greenhouse gas emissions.
• Agricultural Practices:
• Certain agricultural practices, such as rice paddies and livestock farming, can
produce significant amounts of methane.
• Natural Factors:
• Solar Radiation: Variations in the sun's energy reaching the Earth's surface
can influence climate, although these variations are relatively small
compared to the impact of human activities.
• Volcanic Activity: Large volcanic eruptions can inject significant amounts of
ash and gases into the atmosphere, affecting short-term climate patterns.

8. Causes of Climate
Change
• Greenhouse Gas Emissions:
• Carbon Dioxide (CO2): Burning of fossil fuels
(coal, oil, and natural gas) for energy is the
largest single source of global greenhouse gas
emissions.
• Methane (CH4): Released during the production
and transport of coal, oil, and natural gas. It also
results from livestock and other agricultural
practices and by the decay of organic waste in
municipal solid waste landfills.
• Nitrous Oxide (N2O): Agricultural and industrial
activities, as well as the burning of fossil fuels
and solid waste, contribute to nitrous oxide
emissions.

9. Deforestation:
• The clearing of
forests for
agriculture, logging,
and urban
development
reduces the number
of trees available to
absorb atmospheric
carbon dioxide.
Land Use Changes:
• Alterations in land
use, such as
urbanization and
changes in
agricultural
practices, can
influence local and
regional climate
patterns.
Industrial Processes:
• Certain industrial
activities release
greenhouse gases
and other
pollutants directly
into the
atmosphere.

10. Waste Management:
Landfills and waste treatment processes can
produce methane, a potent greenhouse gas.
Changes in Energy Use:
The transition from traditional energy sources to
more carbon-intensive fossil fuels has increased
greenhouse gas emissions.
Agricultural Practices:
Certain agricultural practices, such as rice
paddies and livestock farming, can produce
significant amounts of methane

11. Climate Change and
Global Health
• Climate change poses significant threats to global
health by exacerbating existing health problems and
creating new challenges. Rising temperatures contribute
to the spread of infectious diseases like malaria and
dengue fever as vectors expand their habitats. Extreme
weather events increase the frequency of natural
disasters, causing injuries, displacement, and disruptions
to healthcare systems. Changes in precipitation patterns
affect water and food security, leading to malnutrition
and waterborne diseases. Air pollution from burning
fossil fuels worsens respiratory conditions. Vulnerable
populations, particularly in low-income countries, face
the greatest risks. Addressing climate change is crucial to
safeguarding global health and promoting resilient
healthcare infrastructure.

12. Why should we take
Action on climate change
• Taking action on climate change is imperative for
several reasons. It is an urgent response to protect
ecosystems, biodiversity, and natural resources from
irreversible damage. The escalating frequency of
extreme weather events threatens communities,
economies, and food security. Climate change
contributes to the spread of diseases and environmental
hazards, impacting global health. Importantly,
addressing climate change is a moral duty to reduce
social inequalities and protect vulnerable populations.
By mitigating climate change, we strive for a sustainable
future that ensures the well-being of both the planet
and its inhabitants, emphasizing a responsible and
ethical approach to environmental stewardship.

13. How We Can Take Action
On Climate Change
Taking action on climate change requires collective
efforts. Individuals can adopt sustainable practices
like reducing energy consumption, using renewable
energy sources, and minimizing waste. Supporting
clean transportation and advocating for
environmentally-friendly policies are impactful
steps. Businesses should embrace sustainable
practices, reduce emissions, and invest in green
technologies. Governments play a pivotal role by
implementing and enforcing climate policies,
investing in renewable energy infrastructure, and
fostering international cooperation. Education and
raising awareness about climate change are
essential for inspiring widespread action. By
fostering a global commitment to sustainability, we
can collectively mitigate climate change, protect
ecosystems, and ensure a more sustainable future
for generations to come.

14. Conclusion
In conclusion, decisive action on climate change is imperative. The evidence of its impact on
ecosystems, weather patterns, and human health is clear. Urgent measures are needed
globally to mitigate emissions, adapt to changing conditions, and promote sustainability. The
consequences of inaction are profound, affecting the environment, economies, and social
equity. Embracing renewable energy, sustainable practices, and international collaboration is
crucial for a resilient future. Our choices today shape the well-being of future generations,
emphasizing the immediate necessity for a collective commitment to combat climate change.
