3. Introduction to the Carbon Cycle
-Explanation of the natural carbon cycle:
. Carbon reservoirs (atmosphere, oceans,
biosphere, lithosphere)
.Processes involved: photosynthesis,
respiration,decomposition, weathering,
volcanic eruptions .
. Importance of maintaining balance in the cycle
3

4. -Major sources of anthropogenic CO2
emissions:
.Fossil fuel combustion
. Deforestation
.Cement production
-Visual representation of the dramatic
increase in atmospheric CO2 levels over
recent decades
HUMAN IMPACTS ON THE CARBON CYCLE

6. Explanation of the greenhouse effect : how
certain gases like co2 trap heat from the
sun in the atmosphere :
-Without carbon dioxide, Earth's natural
greenhouse effect would be too weak to
keep the average global surface temperature
above freezing.
-By adding more carbon dioxide to the
atmosphere, people are supercharging the
natural greenhouse effect, causing global
temperature to rise .
THE GREEN HOUSE EFFECTS

7. GEOLOGICAL IMPACTS OF RISING CO2
Sea Level Rise:
. Thermal expansion of oceans due to warming
. Melting of polar ice sheets
. Coastal erosion and flooding
. Change in land water storage
. Climate changes
Ocean Acidification :
• Absorption of CO2 by oceans, creating carbonic acid
. Impact on marine ecosystems, particularly coral
reefs
Changes in Weather Patterns:
. Increased frequency and intensity of extreme
weather events (heatwaves, storms, droughts)
. Disruption of precipitation patterns

8. Geological Evidence for Past Climate
Change :
Paleoclimate records:
-Ice cores, tree rings, sediment cores
-Evidence of past periods of high CO2 and
significant climate changes .
Examplesofgeological evidence :
• Tree rings: Canprovide evidence of climate change up
to 9,000 years ago .
• Ice cores: Can provide evidence of climate change up
to 2 million years ago
.Ocean sediments : Can provide evidence of climate
change up to 200 million years ago

10. Reducing CO2 emissions:
.Transition to renewable energy
sources
.Energy efficiency measures
. Carbon capture and
storage technologies
MITIGATION STRATEGIES :

11. -Without carbon dioxide, Earth's natural
greenhouse effect would be too weak to keep
the average global surface temperature above
freezing.
-By adding more carbon dioxide to the
atmosphere, people are supercharging
the natural greenhouse effect, causing
global temperature to rise.
