The document discusses the greenhouse effect and global warming. It defines the greenhouse effect as a natural process that warms the Earth using greenhouse gases like carbon dioxide, methane, nitrous oxide, and ozone. These gases contribute 50%, 19%, 4%, and 8% respectively to the greenhouse effect. Global warming refers to the increase in Earth's average surface temperature caused by the greenhouse effect. The consequences of climate change include rising sea levels, more extreme weather events, droughts, and diseases. The document urges reducing activities that cause global warming like using fossil fuels in order to save the planet.

4. Green House Effect
The greenhouse effect is a natural process that
warms the Earth's surface. When the Sun's
energy reaches the Earth's atmosphere, some of
it is reflected back to space and the rest is
absorbed and re-radiated by greenhouse gases.

5. What are Greenhouse Gases?
Carbon Dioxide
Chlorofluorocarbons
Methane
Nitrous Oxide
Ozone
Water Vapors

7. Greenhouse Farming

8. Advantages of Greenhouse Effect
Without the greenhouse gases, all
heat coming from the sun would
have escaped from the Earth and
it would have become cold and
barren.

12. What is Global Warming?
The increase of Earth’s average
surface temperature due to effect
of greenhouse effect gases.
Also referred to as Climate Change.

13. Consequences of Climate Change

14. Effects of Global Warming
Sea level rises (SLR)
Hurricanes and other storms
Flood
Drought
Less fresh water
Diseases like Malaria

15. Report By NASA
The planet's average surface temperature
has risen about 2.0 degrees Fahrenheit. A
change driven largely by increased carbon
dioxide and other human-made
emissions. Most of the warming occurred in
the past 35 years, with 16 of the 17 warmest
years on record occurring since 2001. But
2016 the warmest year on record.

16. Ways of reducing Global Warming
→Plant more trees
→Minimize use of automobiles
→Avoid excessive burning of fuel
→Save energy
→Reduce waste

17. Save your Mother Earth

18. Final Thoughts :
• Global warming is real.
• Will affect more than our generation.
• All citizens of Earth must act.
• We only get one planet let’s not
destroy it.
• Save your Mother Earth.
