101 are seasons is climate of pune changing jnana probodhini prashala Presentation Transcript

  • 1. By Pranav, Anoop& Shivanand
  • 2.  What is climate change Greenhouse effect Introduction Causes of climate change Effects of climate change Recommendations Sources
  • 3.  The climate of a region is defined by the average temperature, humidity, wind direction and sunshine of the region. If all this changes considerably, we may say that ‘climate change’ has occurred. Throughout the earth’s history ,there have been changes in climate and that’s why evolution and adaptation has taken place. So we may say that the climate of the earth is ever changing
  • 4.  The earth receives energy from sun mostly in visible and UV spectrum. When this energy is gained by earth, she reradiates it back in form of IR radiation. This IR radiation is absorbed by GHGs (as they are IR active)and is liberated back in atmosphere. This cycle helps earth keep warm or else the average earth’s temperature would be 1celcius
  • 5.  Activitiesthat generate GHGs are called sources and those that remove them are called sinks. When the cycle of source-sinks is disturbed, climate change occurs. This is caused by either internal or external changes occurring regarding earth. Our focus is on external changes.
  • 6. HUMAN NATURAL Agriculture  Sun storms Deforestation  Volcanic eruptions Pollution  Heat waves  Chill waves  Current changes
  • 7.  CH4 is emitted on a large scale by cows and bulls which are ruminating animals. Every time, when they digest food CH4 is liberated. It is about 70-120 kg methane in a year !! Another 15-20% of the total CH4 emissions come from paddy fields that are flooded during sowing and maturing periods.
  • 8.  Nearly 90%of the paddy area is done in Asia. Large paddy plantations are existing inTamhini ghat and in the small towns near pune. A large volume of N2O emissions has been attributed to fertilizer application. But still, our farmers use 4 times more fertilizers than expected. Also, N2O is 200 times more stronger GHG than CO2.
  • 9.  62000 trees are cut in last 7 years in Pune (legally). The hills in Pune-ARAI tekdi, parvati, taljai are the only carbon sinks of Pune we should try to conserve them. Govn has allowed 40% construction on such hills. We think this should be opposed. 20% of global greenhouse gas emissions result from deforestation and degradation of forest.
  • 10.  Forests contain about 125 percent of the carbon found in the atmosphere. This carbon is stored in the form of wood and vegetation through "carbon sequestration". Deforestation will also disturb the ‘carbon cycle’ This will again boost carbon production and the cycle will go stronger and stronger along time.
  • 11. Private As we all know, Pune has the maximum number of two wheelers in the world.(19 lakh) So our city’s maximum source of pollution is vehicles . On average, 0.62 lbsCO2/mile is released by a vehicle in pune. So about 120lakh pounds of co2 & 60000 RSPM is released every day by vehicles alone.
  • 12. LAXMI ROAD NO TRAFFIC SENSE
  • 13.  There are 10 power plants in or on the outskirts of Pune. On average,300lbs co2 is produced by those in a day. A study has shown that about 3030 kg rspm is released in air by small scale power plants in a day
  • 14.  According to a study, 1 degree Celsius rise in climate of Pune will do 3-7% loss on potatoes, soybean, mustard and WHEAT!! By 2050, 20% loss on almost all crops is expected in Maharashtra. Good thing is that increase of co2 levels in Pune(550ppm) has brought 15% increase in rice and legumes.
  • 15.  Increased droughts and floods will affect availability of crops in future. Animal distress due to heat .Effects on reproduction and milk quantity have occurred. So loss of 1.5 million tons of milk is expected by 2020 in Maharashtra. Cases of extreme rain fall have doubled in Pune in 50 years. This has affected mango market in Pune.
  • 16.  Vector borne diseases have increased alarmingly in recent years as warmer climate is suitable for mosquitoes to survive and reproduce. 160 deaths were recorded in 10 yrs due to malaria in Pune.
  • 17.  Pune’s biomes having short lifespan of 50 yrs are still most vulnerable to projected climate change. Vetal tekdi has seen 10% loss in its forest cover since 2000. Good thing is increased CO2 levels have boosted forest productivity in Maharashtra by 15%
  • 18.  15-40% of species will face extinction in India with rise in 2 degree Celsius(50 years from now). As we will see next by the graphs done by ourselves, average temperatures will go increasing. So biomes will be disturbed greatly resulting loss of chances of survival of species.
  • 19.  As we can see the required rainfall for Pune to meet its needs is 1150.3mm. Average rainfall of Pune is 798.2 mm But this feat has never been achieved in last 50 years. So we must reconsider this issue seriously and improve forest cover.
  • 20.  Ifyou are idling your vehicle for more than 10sec, then you must turn the engine off as it gives more CO2 than starting the engine. About 80 vehicles were standing at S.P college chowk for 90 seconds(this is done by ourself). According to carbon footprint meter,idling vehicle for 1 min=1mile=0.80lbs carbon
  • 21. ReccomendationsSo 96 pounds of carbon is released in just 1 chowkof Pune in just 1 minute.Imagine the number of such chowks in Pune andthe CO2 releasedin such chowks.And imagine the CO2 released in 1 day. WE JUST TURN OFF CAR ATSIGNALS, WE MAKE ADIFFERENCE!!!!
