    3. 3. The Himalaya The global climate is changing and it is likely to change further over coming decades due to increasing concentrations of ‘ greenhouse gases’ in the earth’s atmosphere caused largely by human activities. This will result in greater variations in weather patterns, a greater frequency of extreme weather events such as floods , droughts and tropical storms , and gradual rises in average temperatures and sea-levels . Bangladesh is extremely vulnerable to climate change impacts because of its geographical location , high population density , high levels of poverty , and the reliance of many livelihoods on climate-sensitive sectors, particularly rural agriculture and fisheries. CC will reduce the 30% of crop production since 1950 If MSL increases 1 m, 2500 sq km of Goran forest will destroy 20% of land of Bangladesh will go under water

    16. 22. How Does it Work??
    17. 23. <ul><li>Greenhouse gases act as insulators of heat, some heat is absorbed, while some is reflected back to space </li></ul><ul><li>Over the years there has been an increase in Greenhouse gases especially carbon </li></ul><ul><li>The blanket of insulating gases thickens, and more and more heat in trapped within the atmosphere. </li></ul>
    18. 24. Its here…
    19. 25. Correleation
    20. 26. Other Correlations
    21. 27. What Now? <ul><li>The Greenhouse effect has happened for along time, naturally. </li></ul><ul><li>It is only until the immense increase in carbon dioxide and other greenhouse gas emissions that made it an excessive process. </li></ul>
    22. 28. Effects <ul><li>Increased Sea Level </li></ul><ul><li>Coastal Cities Effected </li></ul>

    24. 41. Impact of Climate Change on Water Resources <ul><li>Impacts: </li></ul><ul><li>Increase annual precipitation by 10-15% (estimated for 2030) </li></ul><ul><li>Increased precipitation and evaporation will affect mean run-off, frequency, and intensity of floods and drought, soil moisture, and surface and ground water availability in GBM region </li></ul><ul><li>Consequently, these changes has a substantial effect on – </li></ul><ul><li>- agriculture </li></ul><ul><li>- fishery </li></ul><ul><li>- navigation </li></ul><ul><li>- industrial and domestic water supply </li></ul><ul><li>- salinity control and </li></ul><ul><li>- reservoir storage and operation </li></ul>

    26. 43. Impacts on Drought/ dry lands /desertification/ deserts <ul><li>Deserts are very dry places. Some of them get less than 10 inches of rain in a whole year. </li></ul><ul><li>Because there is little water, very few plants grow, so there is no shade. </li></ul><ul><li>Deserts get cold at night because there are no plants to hold the heat on the ground and because dry air cools quickly. </li></ul><ul><li>Dry lands becomes more hotter and drier </li></ul><ul><li>Severe hot and cold may extinct desert biodiversity </li></ul><ul><li>Succulent Carrow well known Desert ecosystem is under threat </li></ul>
    27. 44. CC Impacts on Health <ul><li>Global warming will possibly: </li></ul><ul><li>enhance the vector- borne and water-borne diseases in the tropics (IPCC 2001). </li></ul><ul><li>Increase incidences of diseases such as </li></ul><ul><ul><li>diarrhea, skin diseases, asthma, hypertension and malaria and dengue, loss of human lives, Impact on mental health </li></ul></ul><ul><li>Sanitation facilities will be acuter (WRI, 1998). </li></ul><ul><ul><li>Increased risk of water borne diseases as a result of disruption of water supply and sewage system </li></ul></ul>
    28. 45. Supply and Demand <ul><li>One important resource for the future is water </li></ul><ul><li>As global temperatures increase, certain areas will experience drought while others will experience flooding, thus contaminating fresh water. </li></ul>

    35. 52. CC impacts on Glaciers &quot;Glaciers in the Himalayas are receding faster than in any other part of the world,&quot; according to Syed Iqbal Hasnain from the International Commission for Snow and Ice (ICSI) and the School of Environmental Studies of India's Jawaharlal Nehru University in New Delhi . &quot;If the present rate continues, the likelihood of them disappearing by the year 2035 is very high.&quot;
    36. 53. CC impacts on Glacier The Gangotri glacier, source of the river Ganges, has been receding (10-30m/yr) at alarming rate. Environmentalists fear that if urgent measures are not undertaken, a time may come when Ganges may just disappear. Gangotri glacier… Drying up due to deforestation. Picture Source NASA
