  3. 3. What is Global Warming?An Introduction Global warming is the rise in the average temperature of Earths atmosphereand oceans since the late 19th century and its projected continuation. Since theearly 20th century, Warming and related changes will vary from region to region around the globe. Warming is expected to be strongest in the Arctic and would be associated withthe continuing retreat of glaciers, permafrost and sea ice. Proposed policy responses to global warming include mitigation by emissionsreduction, adaptation to its effects, and possible future reengineering. The premise of global warming as an issue of debate is that industrial growthcoupled with non-structured methods we as humans use to sustain ourselves hascreated a situation where our planet is getting progressively hotter.
  4. 4. So what causes Global Warming?Its causes include:Carbon Dioxide emissions from fossil fuelsIncrease in usage of chemical fertilizersDeforestationMethane emissionsPollution
  5. 5. Climate ModelsCurrent Indexand Projections
  6. 6. The Predictions
  7. 7. EffectsThe effects of Global Warming include:o Rise in sea levels, worldwideo More Killer storms, by which I amreferring to more severe Cyclones andHurricaneso Massive Crop Failureso Widespread extinction of specieso Disappearance of coral reefs
  8. 8. Planning MitigationAdaptation GeoengineeringResponsesResponses to Global Warming
  9. 9. There are different views over what the appropriatepolicy response to climate change should be. Thesecompeting views weigh the benefits of limitingemissions of greenhouse gases against the costs. Ingeneral, it seems likely that climate change will imposegreater damages and risks in poorer regions.
  10. 10. ControversyThe global warming controversy refers to a variety ofdisputes, significantly more pronounced in the popular mediathan in the scientific literature, regarding the nature, causes, andconsequences of global warming.The disputed issues include the causes of increased globalaverage air temperature.There is a strong consensus that global surface temperatureshave increased in recent decades and that the trend is causedmainly by human-induced emissions of greenhouse gases.A few organisations hold non-committal positions.
  11. 11. What can YOU do to save Earth?Every person is responsible for anything bad that Global Warmingcauses, which eventually decreases the life of our very own planet.So its your fundamental duty to help protect Earth by doing yourpart. Here’s what you can do: Plant trees. If you already have, plant more! Try using fuel efficient vehicles, or vehicles that run on gasessuch as LPG. Save Electricity Whenever you spot someone cutting down a tree, make surethat you atleast stop that person and explain how severe theconsequences could be. Spread knowledge about how chemical fertilizers should not beused in bulk and its high time that we switch to environment-friendly alternatives.
