3. What is climate change?
A change in global or regional climate patterns, in
particular a change apparent from the mid to late
20th century onwards and attributed largely to
the increased levels of atmospheric carbon
dioxide produced by the use of fossil fuels.

5. Causes of climate
change
 Greenhouse gases
• Greenhouse gases are thought to be
the main contributor to climate change.
They are very efficient in trapping heat
into the atmosphere; therefore, it
results in the greenhouse effect

7.  Nature
• nature also contribute to climate change by
emitting CO2 from volcanos.
• According to NASA, on average, volcanoes
emit between 130 and 230 million tons of
CO2 per year.
• However, by burning fossil fuels, people
release in excess of 100 times more, about
26 billion tons of CO2, into the atmosphere
every year

 Human
Contributions
• A large amount of climate change happens
widely because we are burning fossil fuels
and that increases gases such as CO2,
methane, and some other gases in the
atmosphere.
• The world depends on fossil fuels such as
oil, coal, and natural gas for 80% of its
energy needs.

11. Effect of climate change
⪢ Warmer temperatures increase the
frequency, intensity, and duration
of heat waves, which can
pose health risks, particularly
for young children and the elderly.
⪢ Rising sea level threatens coastal
communities and ecosystems.
⪢ Climate change can also
impact human health by worsening
air and water quality.

13.  Changing ecosystems influence
geographic ranges of many plant
and animal species and the
timing of their lifecycle events,
such as migration and
reproduction
 Changes in the patterns and
amount of rainfall effect water
supplies and water quality and
the production of
hydroelectricity.

15. Solutions
 Keep fossil fuels in the ground.
 Invest in renewable energy.
 Switch to sustainable transport.
 Reduce plastic.
 Protect the oceans.
 Protect forests like the Amazon.
