2. Climate:
• It is a set of meteorological elements that
characterize the average state of the
atmosphere of a place

3. Climate:

4. Climate:

5. Climate change:
• The current climate change: A stronger
than expected, sooner than anticipated
• Warming on Earth is a fact - the Earth's
surface temperatures in the 20 th century
have risen by 0,6 º C, and 90 years
proved to be the hottest decade of the
last century

6. The facts:
• Raising the temperature by 1880 to our
days with ~ 1C

7. The facts:
• Warming in the Arctic and Antarctica
and the melting ice caused sea level rise
and flooding of low fertile lands and
coasts

8. The facts:
• Change the quantity of rainfall on the
ground, leading to frequent
unpredictable floods or prolonged
droughts

9. The facts:
• Scientists are almost unanimous that
global warming is the result of emissions
of carbon dioxide and other gases –
which cause the Greenhouse Effect

10. The facts:
• A change of global temperature and
Carbon Dioxide

11. The Greenhouse Effect:
• The observations
show an increased
temperature of the
low strata of the
atmosphere in
comparison with
thermal radiation of
the planet

12. The Greenhouse Effect:
• Main greenhouse gases
Gas Contribution rates
Contribution rates 55%
Carbon dioxide 39%
Ozone 2%
Methane 2%
Nitrogenous oxide 2%

13. Concentrations of greenhouse
gases in the atmosphere:

14. Major sources of emissions:

15. The consequences:
• Running out of the stock of fresh water
• Destruction of ecosystems and loss of
biodiversity
• Reduction of volume and productivity of
arable land
• Destruction of forests due to fires because of
drought and high temperatures
• Increasing of deserts and melting of mountain
glaciers
• Global climate change has an impact on
human health

16. The consequences:
• Rising of the level of the World ocean (at an
average 0.2cm /year)
• Earthquakes
• Fires
• And more,
and more …

17. The near future of Bulgaria…
• Desertification of arable agricultural
land
• Very high risk of flooding caused by the
rapid melting of mountain snow
• Sharp increase in fires and almost
complete destruction of Bulgarian forest
• Emergence and spread of new diseases
and pests to our region
• And more, and more…

18. What is being done globally:
• Increasing the share of renewables
• Reducing the harmful emissions
• Increasing energy efficiency
• Collaboration

19. How to help?
• Remember: Everyone is part of the solution!!!
• Use energy saving lamps
• Recycle
• Turn off the lights that you don’t use
• Maximize your home heating - use insulations
• Switch off electrical appliances from the
‘on’/’off’ button
• Use environmentally friendly transport
• Use rechargeable batteries

20. How to help?
• Try to use renewable energy
• Make sure that your new appliance is energy
class A or A+
• Announce against deforestation
• Explain all this to your friends
• Plant a tree
