This document discusses climate change and its causes and consequences. It explains that climate change is a change in the Earth's climate over a long period that used to be natural but is now mainly caused by human activities like industry and technology. It lists greenhouse gases like CO2 and CH4 as contributing to global temperature rise, melting ice caps and glaciers, sea level rise, extreme weather, and health problems. Scientists estimate global temperature could increase by 5.8°C by 2100 or 4°C by 2040 if emissions are not reduced.

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.

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.

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.

Northwest Passage can open up
melting of ice caps and glaciers
glaciers can disappear

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.
