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!
