1. Greenhouse effect what is it?

2.  In the absence of the greenhouse effect and an atmosphere, the Earth's average surface temperature of 14 °C (57 °F) could be as low as −18 °C (−0.4 °F), the black body temperature of the Earth. Without the greenhouse effect, the planet would be an uninhabitable, frozen wasteland.

4. Which are the greenhouse gases  water vapor, which contributes 36–70% which contributes 36–70%  carbon dioxide, which contributes 9–26% which contributes 9–26%  methane, which contributes 4–9% which contributes 4–9%  ozone, which contributes 3–7% which contributes 3–7%

5. Other greenhouse gases  nitrous oxide  CFCs

6. Is there evidence for global warming? It appears that there is a temperature increase of 0.5 o C the last 100 years It appears that there is a temperature increase of 0.5 o C the last 100 years

7. What is the relationship between global warming and greenhouse gases ? Can you see the similarity?! Can you see the similarity?!

8. The impact of global warming in Europe Southeastern Norway Southeastern Norway The year 2000 was the wettest year since records began in 1895. The year 2000 was the wettest year since records began in 1895. Samos Island, Greece Samos Island, Greece July 2000 Fires due to dry conditions and record-breaking heat consumed one-fifth of the island. July 2000 Fires due to dry conditions and record-breaking heat consumed one-fifth of the island. Caucasus Mountains, Russia Caucasus Mountains, Russia Half of all glacial ice disappeared in the past 100 years. Half of all glacial ice disappeared in the past 100 years. Arctic Ocean Arctic Ocean The area of perennial ice cover has decreased by about 7% per decade since 1978. The area of perennial ice cover has decreased by about 7% per decade since 1978. …and so on …and so on

9. What will happen in the future if we do nothing?  Increase in average surface air temperature of about 2.5°C by the year 2100.  More "killer" heat waves during the warm season  Rise of sea-level by approximately 49 cm over the next 100 years.

10. CO 2 and fossil fuels 1.Fossil fuels burning produces CO 2 2. CO 2 is accumulating in the atmosphere 3.Heat from solar energy is trapped beneath CO 2 layer 4.Temperature of the atmosphere becomes higher

11. Global annual CO 2 emissions 23.579 million tones of CO2 are emitted annually from human activities Only 20% of energy used does not produce CO2

12. The Kyoto Protocol  The Kyoto Protocol is an international agreement linked to the United Nations Framework Convention on Climate Change. The major feature of the Kyoto Protocol is that it sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas (GHG) emissions.These amount to an average of five per cent against 1990 levels over the five-year period 2008-2012.

13. But are the European member states meeting their Kyoto 2012 carbon dioxide(CO2) emission targets? The 2010 projection figures are based on existing domestic policies and measures, already implemented by the member states. Figures are in Megaton (Mt CO2-eq). But are the European member states meeting their Kyoto 2012 carbon dioxide(CO2) emission targets? The 2010 projection figures are based on existing domestic policies and measures, already implemented by the member states. Figures are in Megaton (Mt CO2-eq).

14.  The average European produces 11 tonnes of 11 tonnes of CO 2 equivalent per year CO 2 equivalent per year

15.  What can we do as individuals individuals in order to reduce in order to reduce Carbon Dioxide Emissions ? Carbon Dioxide Emissions ?

16. Four simple steps  1 Turn down  2 Switch off  3 Recycle  4 Walk

17. Turn down Do you know that  If you reduce the temperature of your home by just 1°C you save up to 300 kg CO2 per household and year

18. Switch off Do you know that  If you switch off five 60 W lights in hallways and rooms of your house when you don’t need them (about 4 hours per day) you save about 270 kg CO2 per year

19. Recycle Do you know that  If you recycle 1 kg of aluminium you save about 9 kg CO2.  If you recycle 1 kg of aluminium you save about 9 kg CO2.

20. Walk Do you know that  If you replace your short car journeys (about 6 Km per day) with biking you avoid about 240 kg CO2 per year.  If you replace your short car journeys (about 6 Km per day) with biking you avoid about 240 kg CO2 per year.

21.  The members of our team found their Carbon Footprint and made a Carbon Footprint Carbon Footprint pledge pledge

22. We follow the four simple steps and we save !!! we save !!!

23. Konstantina 968 Kg CO 2 per year

24. Emmanuel 2555 Kg CO 2 per year 2555 Kg CO 2 per year

25. Christina 3419 Kg CO2 per year

26. Aristoteles 3819 Kg CO2 per year

27. Antonis 4097 Kg CO2 per year

28. Elena 4103 Kg CO2 per year

29. Timos 6347 Kg CO2 per year
