WHAT IS CLIMATE CHANGE?
• Change of weather patterns
• Average weather
=> more or fewer extreme weather events
for example: hurricanes, tornadoes, tsunamis...
CAUSES
HUMAN NATURE
Burning of fossil fuels Volcanic activity
Agriculture => industry The Greenhouse effect
Reinforce the Greenhouse effect The Earth’s orbit around the sun
100%
70%
30%
50%
20%
25%
45%
PROBLEMS
• Seasons are shifting
• Temperatures ↑
=> Sea levels ↑
SOLUTIONS
In December 2009 scientists set a target to stop the climate change:
- Until 2050 the average temperature shouldn’t rise more than 2°C
- Companies have to pay for the amount of CO2 they produce
- All of us need to reduce the consumption of meat
- What everyone can do is:
- Reduce heating
- TV not on standby
- Watch less TV
IMPACTS
North America:
- Less snow (western mountains)
- Heat waves
Latin America:
- Tropical forests are more and more replaced by savanna
- Species extinction increases
- Changes in water availability
Africa:
- Agricultural production is compromised
IMPACTS
Europe:
- Inland flash floods
- Costal flooding
- Less winter tourism
- Less productive crop (Southern Europe)
Asia:
- Risk of flooding in coastal areas
- Death rate rises in some regions
Others:
- Cultures become extinct
- Sea gets more acidic loss of biodiversity
FUTURE TRENDS
Very likely to occure:
- Extremely hot weather periods
- Rainfall increases in high latitude floods
- Rainfall decreases in subtropical land regions draughts
Likely to occure:
- Tropical cyclone intensity increases
High confidence:
- Decreasing water resources in semi-arid areas
