The presentation discusses climate change, defining it as a long-term alteration of weather patterns influenced primarily by greenhouse gases resulting from fossil fuel combustion and deforestation. It highlights the impact of climate change, including droughts, floods, loss of biodiversity, and the aggravation of natural disasters like cyclones and wildfires. Solutions proposed include investing in renewable energy, sustainable transport, and adaptation and mitigation strategies to reduce greenhouse gas emissions.

3. What is Climate Change
• Climate change is a long-term change in the
average weather patterns that have come to
define Earth's local, regional and global
climates.

Burning
Fossil Fuel
When fossil fuels are
burned, they release
nitrogen oxides into
the atmosphere, which
contribute to the
formation of smog and
acid rain. The most
common nitrogen-
related compounds
emitted into the air
by human activities
are collectively
referred to as
These Gases

temperature over the
World. 7

Deforestatio
n
•The action of clearing a wide area of trees.
The effects of
deforestation
The three main consequences of
deforestation are:
Loss of biodiversity
Soil degradation
Global warming

Drought
A drought is a period of drier-than-normal conditions that results
in water-related problems.
Whenever the Earth’s
tempareture is
increasing due to
climate changes then
Drought is occurred.

Flood
As warmer temperatures
cause more water to
evaporate from the land
and oceans, changes in the
size and frequency
of heavy precipitation
events may in turn affect
the size and frequency of
river flooding.

Forest Fire
As a driver of

wildfires release
huge quantities of
greenhouse gases

Industrial
revolution
Many scientists believe, however, that with
the dawn of the industrial age—and the
burning of fossil fuels such as coal,
natural gas, and oil—humans began
to significantly add to the amounts of
carbon dioxide and other greenhouse
gases in the atmosphere, enhancing the
planet's natural greenhouse effect and
causing higher temperatures.
