  1. Global Warming&The Mediterranean Sea

  2. The Mediterranean Sea • Derived from the Latin medium (middle) and terra (earth) – sea in the middle of the earth • Is surrounded by 3 continents Africa, Europe & Asia • Is surrounded by 20 countries • Is connected to the Indian Ocean and the Atlantic Ocean • Is warm & highly saline – leading to scarcity of sea life as visible by its intense blue colour Lily of the Valley GSS, Mosta

  3. What is global warming? Lily of the Valley GSS, Mosta

  4. Most electric power stations still burn fossil fuels to generate electricity. • When fossil fuels are burnt many greenhouse gases are released in the atmosphere. Burning of Fossil fuels Lily of the Valley GSS, Mosta

  5. http://www.visionlearning.com The effect of CO2 in the atmosphere All models show that doubling the amount of CO2 in the atmosphere will result in a rise of 2o to 4oK over the Mediterranean area. Lily of the Valley GSS, Mosta

  6. Greenhouse Effect The Sun’s energy passes through the car’s glasspanes. This heat energy is trapped inside the car and cannot pass back through the glass, causing the inside of the car to warm up. Lily of the Valley GSS, Mosta

  7. What are the effects of global warming on the Mediterranean Sea? Lily of the Valley GSS, Mosta

  8. Recent pictures of Venice Rise in the sea water levels Global warming leads to melting of the arctic ice which leads to the rise of water level across the globe.  Since the Mediterranean Sea is connected to Atlantic Ocean its water level will rise. Lily of the Valley GSS, Mosta

  9. Hurricanes • Global warming could trigger hurricanes • Hurricanes currently form in the tropical Atlantic ocean and rarely reach Europe • A rise in temperature could set off hurricanes to start in the Mediterranean in the future • This would lead to damage of the coastal settlements around the Mediterranean Lily of the Valley GSS, Mosta

  10. http://www.aerospaceweb.org More about Hurricanes Hurricanes form when the energy released by the condensation of moisture in rising air causes a positive feedback loop. The air heats up, rising further, which leads to more condensation. The air flowing out of the top of this chimney drops towards the ground, forming powerful winds Lily of the Valley GSS, Mosta

  11. Thermal expansion of the sea • Global warming heats up the seas. Sea water expands on heating • Thermal expansion has already raised the oceans 10 to 20 centimetres • This should be added to the possibility that Greenland’s massive ice sheets were to melt Lily of the Valley GSS, Mosta

  12. http://dataservice.eea.europa.eu/atlas/viewdata/viewpub.asp?id=2928http://dataservice.eea.europa.eu/atlas/viewdata/viewpub.asp?id=2928 Observed Climate change in the Mediterranean sea Lily of the Valley GSS, Mosta

  13. Can WE do something about it? • Turn off the computer or the TV when I am not using it. • Take shorter showers. Heating water uses energy. • Keep the rooms cool by closing the blinds, shades or curtains. • Turn off the lights when I leave a room. • Dress lightly when it’s hot instead of turning up the air conditioning or use a fan. • Dress warmly when it’s cold instead of turning up the heater. • Offer to help my parents to keep the air filters of the air-conditioner clean. • Walk short distances instead of asking for a ride in the car.

  14. What are the projections for the Mediterranean region? Lily of the Valley GSS, Mosta

  15. Higher temperatures • Rise in sea level; re-design of low-lying coastal areas • Plant species will be endangered • Species living in and around the sea will be endangered • New diseases in the Mediterranean region Lily of the Valley GSS, Mosta

  16. Agriculture Biodiversity Tourism Health The Economy www2.warwick.ac.uk/ These sectors may be affected negatively Lily of the Valley GSS, Mosta

  17. What is happening in Cyprus? • Average temperature increased by 0.8oC in the last 30 year period • Precipitation dropped by 17% in the second half of the 20th century • Cyprus is importing drinking water from Greece Lily of the Valley GSS, Mosta

  18. What is happening in Malta? • There has been an increase of 3oC in the last 100 years • Precipitation dropped by 20% • This has lead of a drop in the water table reservoir • Soil is drier and contains more salinity Lily of the Valley GSS, Mosta

  19. http://media.learningfundamentals.com.au A mind map about global warming Lily of the Valley GSS, Mosta
