2. Objectives
• To understand major consequences of climate
change (CC) in this century and beyond.

3. Content
Introduction
Negative Impacts of CC
• Physical Impacts
• Ecological Impacts
• Socio-economic Impacts
Positive Impacts of CC

4. There’s no such thing as a free lunch.

7. Introduction
When you change the climate you change
every thing.
It effects people and nature in countless ways.
Impact on ecosystems, economics and
communities.

8. Negative Impacts of CC
Physical impacts
 Raise in global temperature
• Heat weaves
 Rising sea level
• Melting polar ice
• Loss of mountain glaciers and snow pack
• Expansion of the oceans
 Increase in extreme events
• Stronger hurricanes
• More droughts and flooding

10. Ecological Impacts
Shifts in species ranges and phenology
• 130 species, both plants and animals have responded
to earlier spring warming
• 1400 species are listed endangered due to CC- Red
list
 Wildfire, drought and insects
• Increase in global temperature
• Drying of spring, ground water depletion

11. Invasive species
Agricultural shifts
Ocean acidification
• Emission of carbon dioxide
• Dissolve of carbon dioxide in seawater

12. Socio- Economic Impacts
Equity and Inequality
Health
• Infectious diseases
• Water borne diseases
• Food borne diseases
• Vector borne disease
• Respirator illness
• Diabetes/Hypertension/Obesity

13. Social conflict
Community will be forced to relocate
Risk and property households
Agriculture, transportation and food

14. .
Positive Impacts of CC
Fewer winter deaths
Lower energy costs
Better agricultural yields
Probably fewer droughts
May be richer biodiversity

15. Thank You!
