CLIMATE CHANGE
and global warming
Johanna Kleine-Frauns
Overview
• Reasons for global warming
• Greenhouse gasses and greenhouse effect
• What is going to happen
• What can we do?
Natural reasons for global warming
• Changes in solar radiation
• Volcanic eruptions
• Natural fluctuations
Human reasons for global warming
• Fossil fuels– carbon dioxide (CO2)
• Deforestation– CO2 emissions can`t
decrease
• Factory farming– methane (CH4)
Greehouse gasses and greenhouse effect
• gasses accumulate
in the atmosphere
• the energy is absorbed within the atmosphere
• The temperature increased
approximately 0.74°C
• By 2100 the global warming could increase up to 6.5°C
Consequences• Increased glacier melt
and melting polar ice caps
• Rising sea levels
• changing rainfall patterns
• increasing weather extremes
What can we do to fight it?
• Turn down
• Choose low energy models
• Switch off
• Think efficient
• Intelligent transport
• Reuse/recycle
Thank you for listening!
