Climate changes

  1. 1. Climate changes Dilyana Grozeva teacher of biology and health education Georgi Izmirliev High school, town Gorna Oryahovitsa
  2. 2. Climate: • It is a set of meteorological elements that characterize the average state of the atmosphere of a place
  3. 3. Climate:
  4. 4. Climate:
  5. 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. 6. The facts: • Raising the temperature by 1880 to our days with ~ 1C
  7. 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. 8. The facts: • Change the quantity of rainfall on the ground, leading to frequent unpredictable floods or prolonged droughts
  9. 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. 10. The facts: • A change of global temperature and Carbon Dioxide
  11. 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. 12. The Greenhouse Effect: • Main greenhouse gases Gas Contribution rates Contribution rates 55% Carbon dioxide 39% Ozone 2% Methane 2% Nitrogenous oxide 2%
  13. 13. Concentrations of greenhouse gases in the atmosphere:
  14. 14. Major sources of emissions:
  15. 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. 16. The consequences: • Rising of the level of the World ocean (at an average 0.2cm /year) • Earthquakes • Fires • And more, and more …
  17. 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. 18. What is being done globally: • Increasing the share of renewables • Reducing the harmful emissions • Increasing energy efficiency • Collaboration
  19. 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. 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
