1. ˝Don’t play games with me!˝
(The Earth)
Our view and ideas
on climate change

2. What is climate change?
• It’s a change in the
climate system of the
Earth over a longer
period.
global
warming
greenhouse
effect
climate
change

3. • Climate changes used
to be natural only.
But…
…current changes are
mainly caused by human
activities!

4. The Human Impact
• The industrial and technological revolution
has changed our life.
more food
More people ››› more
water
more energy

5. Greenhouse gases

6. CO2

7. CH4

9. A few consequences…
global rise in temperature
melting of ice caps and glaciers
sea level rise
extreme weather events
migration of species
serious health problems

10. global rise in temperature

11. • According to
scientists, by
2100 global
temperature
could increase
by 5.8°C.
• Other opinion:
4°C rise by
2040.

12. 2006: smallest Arctic ice cap
Northwest Passage can open up
melting of ice caps and glaciers
glaciers can disappear
from high mountains
(the Alps)

13. sea level rise
regions in danger:
- Southeast Asia
- the Far East
- SE part of the US
- island countries
melting can lead to
3-5 m rise in sea level
in the future

14. migration of species
many animals will have to move
many have moved already

15. • burning forests
• drought
• flooding
• storms
• tornadoes
• heat waves
extreme weather events

16. serious health problems

17. Scientific advice for the future
Somehow
we have to control
warming-up.
reduction of
greenhouse
gas emission
turning our life
into energy-
saving mode
