  • 3. 1. Climate and Climate System
    • Climate is collective weather
    • Climate system :
    • atmosphere, hydrosphere, lithosphere, cryosphere, biosphere, radiation
  • 4.  
  • 5. Lithosphere and Biosphere Hydrosphere
  • 6. CRIOSPHERE
  • 7. GREENHOUSE EFFECT
  • 8. - Carbon Dioxide (CO 2 ) - the burning of the fossil fuels - Kyoto Protocol - UN Climate Convention - EU Directives - IPCC Recommendations
  • 9. RADIATIVE FORCING
  • 10. 2. Paleoclimate
  • 11. Earth's Orbital Changes
  • 12. Paleoclimate cycles
  • 13. The Last Interglacial and the Arctic
  • 14. The Last 1000 Years
  • 15. 3. Recent Global Warming
  • 16. Recent Global Warming

  • 19.  
  • 20. 3. Precipitation Amount Trend
  • 21.  
  • 22.  
  • 23. Palmer’s Drought Severity Index
  • 24. 5. Snow and Ice Cover
  • 25. March-April NH Snow Covering Area
  • 26. CHANGE IN SEA ICE EXTENT Arctic Antarctic
  • 27. ARCTIC Summer 1983 Summer 2003
  • 28. 6. Processes in the Oceans
  • 29. PROCESSES IN THE OCEAN

  • 31.  
  • 32. 7. Climate Extremes
  • 33. Cold Extreme Decrease
  • 34. Warm Extreme Increase
  • 35. Extreme Hot Summer 2003 in Central Europe
  • 36. Extreme Warm Summer 2003 in Croatia
  • 37. Extreme Warm Winter 2006/2007 in Croatia
  • 38. Number of Very Wet Day Increase
  • 39. Sahel Recent Drought
  • 40.  
  • 41. 8. Global Climate Scenario
  • 42. Comprehensive Climate Models
  • 43. CO 2 Temperature
  • 44. GLOBAL WARMING PROJECTION
  • 45. Decade Temperature Projection
  • 46. REGIONAL TEMPERATURE PRPJECTION
  • 47. European Temperature Projection
  • 48. EUROPEAN PRECIPITATION PROJECTION
  • 49. Frost Days Heat Waves Growing Season
  • 50.  
  • 51. Precipitation Intensity Dry Days
  • 52. MORE HOT WEATHER
  • 53. Sea Level Rise
  • 54. Sea Level Rise
  • 55. CO 2 Concentration Scenarios
  • 56. 8. Conclusion - Climate has been changed in the past in long time-scale (1000 years) - Recent global warming on a very short i.e. decade scale (10 to 100 years) - very probably (90 %) caused by man - some measure to limit CO 2 emission - Kyoto Protocol, UN Climate Convention, - IPCC - Political decisions are very important - Role of National Meteorological Service - Agencies for Environmental Protection - education of young people
