Global warming Global warming Presentation Transcript

  • -OUR EARTH NEEDS US
  • Definition Global warming usually means a fast, unnatural increase in overall temperature of earth that is enough to cause the expected climate conditions to change rapidly.
  • Greenhouse Effect
  • Causes for Global WarmingRise in CO2 emission.Rise in other green house gases, like methane, Water vapor.Deforestation- burning and cutting millions of acres of trees each year, it is responsible for 20-25 per cent of all carbon emissions.Energy use and production- More than 80% of the world- wide energy demand is currently supplied by the fossil fuels coal, oil or gas.The true cause of global warming is our thoughtless attitude towords Nature.
  • Carbon Dioxide
  • Relation between Temperatureand CO2 Todays 370 parts per million of CO2 is the greatest in 20 million years -- and it is still going up.
  • A Pentagan Report points to possible "catastrophic droughts, famines and riots,with skirmishes over food and water, mass migration and economic disruption.Starvation and disease will decrease population size".The Stern Report says "climate change will affect the basic elements of life (water,food production, health and the environment). Hundreds of millions of people couldbe affected by coastal flooding".
  • Impact of Global WarmingIce Under Fire: Arctic40% REDUCED IN 40 YEARSNEXT 30 YEARS IT WILL BE COMPLETELY GONE IN SUMMER TIME.
  • First, it will raise sea levels.Second, Ice caps are white, and reflect sunlight, much of which is reflected back into space, further cooling Earth.Third, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English - make it less salty.Fourth, temperature rises and changing landscapes in the arctic circle will endanger several species of animals. Only the most adaptable will survive.
  • POLAR BEARS DROWNED SWIMMING LONG DISTANCES.
  • ANTARCTICA- LARGEST ICE SHELVES IN THE WORLD.About 98% of Antarctica is coveredby ice, which averages at least 1.6kilometres (1.0 mi) in thickness.PermafrostPermafrost is a solid structure offrozen soil, extending to depths of2.200 feet in some areas of the arcticand subarctic regions, containinggrasses, roots, sticks, much of itdating back to 30,000 years.
  • The Larsen B sector collapsed and broke up, 3,250 km² of ice 220 m thickdisintegrated in just 35 DAYS. "hotspot of global warming."
  • GREENLAND MELTINGThe rate of ice-mass loss from an island inGreenland increased by 250 percentduring a period spanning May 2004 toApril 2006 relative to the period from April2002 to April 2004,a study concludes.IF ENTIRE GREENLAND OR WESTANTARCTICA MELTS SEA LEVEL RISE 20 FEET Worldwide!
  • GALCIERS MELTING POR TAGE GLACIER 1904CHOOYU GLACIER POR TAGE GLACIER 2004
  • Rongbuk Glacier - Northern slope of Mount EverestIF GLOBAL WARMING CONTINUES AT THIS RATE RIVER GANGA WILL BECOME SEASONAL IN 35 YEARS!!!
  • Warming Winds, Rising Tides:Oceans Coral reefs are probably the most complex ecosystems on the planet, home to hundreds of thousands of species. High water temperatures caused coral bleaching and subsequent death or adverse change to sixteen percent of world reefs overall and up to 46 percent in parts of the Indian Ocean. Aquatic Life Dependent On Them are Dying.
  • OCEAN TEMPERATURE RISE IMPACTS: STRONGER STORMS, TORNADOES, HURRICANS HURRICANE KATRINA –AUGUST 29,2005 INCREASE IN PRECIPITATION – RELOCATED. MUMBAI FLOODS, 26 JULY 2005 37 inches of rain in 24 hrs Water levels reached 7 ft.  MORE WATER EVAPORATION IN OCEAN, LANDS SUCKED UP- SEVER DROUGHTS WIND AND WATER CYCLES CHANGE
  • Pushing the Boundaries of Life:Temperate Zone "We are running into a really serious loss of biodiversity." 2/3 of butterfly species with long observational records had shifted northward by from 22 to 150 miles, consistent with temperature increases in Europe.
  • SOLUTIONSThe Most Important Things You Can Do about Rapid Climate Change:1. Understand the Problem, its causes 2. Do Something Today to Reduce Greenhouse Gas Emissions, find solutions.Its time to ACT."In my view, climate change is the most severe problem that we are facing today -- more serious even than the threat of terrorism." - David A. King, Chief Scientific Advisor to the British Government
