Steps neede to eradicate global warming

  1. 1. Global warming is the rise in the average temperature of Earthsatmosphere and oceans since the late 19th century and its projectedcontinuation. Since the early 20th century, Earths mean surfacetemperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.It’s a fact that our world is warming. Scientific consensus: Global warming is primarily induced by human activities, principally because of greenhouse gas emissions from combustion of fossil fuels. Increased greenhouse gas emissions will result in increased average global temperatures.Atmospheric concentrations of greenhouse gases are the highest in atleast 650,000 years (as measured by Antarctic ice core samples)*Our energy future choices and global warming are inextricably linked.
  2. 2. 1. Carbon dioxide emissions from fossil fuel burningpower plants: Our ever increasing addiction to electricity from coal burningpower plants releases enormous amounts of carbon dioxide into theatmosphere. 40% of U.S. CO2 emissions come from electricityproduction, and burning coal accounts for 93% of emissions from theelectric utility industry .Every day, more electric gadgets flood themarket, and without widespread alternative energy sources, we arehighly dependent on burning coal for our personal and commercialelectrical supply.
  3. 3. 2. Global Warming Cause: Carbon dioxide emissionsfrom burning gasoline for transportation: Our modern car culture and appetite for globally sourced goods isresponsible for about 33% of emissions in the U.S. With our populationgrowing at an alarming rate, the demand for more cars and consumergoods means that we are increasing the use of fossil fuels fortransportation and manufacturing. Our consumption is outpacing ourdiscoveries of ways to mitigate the effects, with no end in sight to ourmassive consumer culture.
  4. 4. 3. Methane emissions from animals, agriculture suchas rice paddies, and from Arctic seabeds: Methane is another extremely potent greenhouse gas, ranking right behind CO2.When organic matter is broken down by bacteria under oxygen-starved conditions(anaerobic decomposition) as in rice paddies, methane is produced. The process alsotakes place in the intestines of herbivorous animals, and with the increase in theamount of concentrated livestock production, the levels of methane released into theatmosphere is increasing. Another source of methane is methane clathrate, acompound containing large amounts of methane trapped in the crystal structure ofice. As methane escapes from the Arctic seabed, the rate of global warming willincrease significantly.
  5. 5. 4. Global Warming Cause: Deforestation, especiallytropical forests for wood, pulp, and farmland: The use of forests for fuel (both wood and for charcoal) is one causeof deforestation, but in the first world, our appetite for wood and paperproducts, our consumption of livestock grazed on former forest land,and the use of tropical forest lands for commodities like palm oilplantations contributes to the mass deforestation of our world. Forestsremove and store carbon dioxide from the atmosphere, and thisdeforestation releases large amounts of carbon, as well as reducing theamount of carbon capture on the planet.
  6. 6. 5. Global Warming Cause: Increase in usage ofchemical fertilizers on croplands: In the last half of the 20th century, the use of chemicalfertilizers (as opposed to the historical use of animal manure) hasrisen dramatically. The high rate of application of nitrogen-richfertilizers has effects on the heat storage of cropland (nitrogenoxides have 300 times more heat-trapping capacity per unit ofvolume than carbon dioxide) and the run-off of excess fertilizerscreates ‘dead-zones’ in our oceans. In addition to these effects,high nitrate levels in groundwater due to over-fertilization arecause for concern for human health.
  7. 7. Scientists predict an increasein sea levels worldwide due tothe melting of two massive icesheets in Antarctica andGreenland, especially on theEast coast of the U.S. However,many nations around the worldwill experience the effects ofrising sea levels, which coulddisplace millions of people. Onenation, the Maldives, is alreadylooking for a new home, thanks
  8. 8. hurricanes and cyclones isincreasing, and research publishedin Nature found:“ScientiStS have come up with thefirmest evidence so far that globalwarming will significantly increasethe intensity of the most extremestorms worldwide. The maximum windspeeds of the strongest tropicalcyclones have increasedsignificantly since 1981, accordingto research published in Nature this
  9. 9. 8. Global Warming Effect: Massive cropfailures: According to recent research, there is a 90% chance that3 billion people worldwide will have to choose betweenmoving their families to milder climes and going hungry dueto climate change within 100 years.“Climate change is expected to have the most severe impacton water supplies. “Shortages in future are likely to threatenfood production, reduce sanitation, hinder economicdevelopment and damage ecosystems. It causes more violentswings between floods and droughts.”" – Guardian: Globalwarming causes 300,000 deaths a year
  10. 10. 9. Global Warming Effect: Widespreadextinction of species: According to research published in Nature, by 2050, risingtemperatures could lead to the extinction of more than amillion species. And because we can’t exist without a diversepopulation of species on Earth, this is scary news for humans.“Climate change now represents at least as great a threat tothe number of species surviving on Earth as habitat-destruction and modification.” Chris Thomas, conservationbiologist at the University of LeedsWidespread species loss and lists of endangered species justkeep growing. This is a concerning matter on many fronts.
  11. 11. 10. Global Warming Effect:Disappearance of coral reefs: A report on coral reefs from WWF says that in a worstcase scenario, coral populations will collapse by 2100 due toincreased temperatures and ocean acidification. The‘bleaching’ of corals from small but prolonged rises in seatemperature is a severe danger for ocean ecosystems, andmany other species in the oceans rely on coral reefs for theirsurvival.
  12. 12. Replace regular bulbs with compact fluorescent light (CFL) bulbs. They consume less powerthen ordinary bulbs and have longer lifetime. Some countries have completely banned theusage of ordinary bulbs and force the common public to use CFL bulbs.These is a method toreduce global warming
  13. 13. By driving less you are not only saving fuel but also helping in reducingglobal warming. Also, look out for other possibilities, for eg: car pooling.If you have colleagues who live in the same area then you can combinetrips. If you need to go to a local market then either walk or go by cycle.Both of them are great form of exercise
  14. 14. Try to use the disposable products into some other form. Just don’tthrow them away. You can recycle almost anything for eg:paper, aluminum foils, cans, newspapers. By recycling you can help inreducing landfills .
  15. 15. When you drive make sure your tyres are inflated properly. If not,then obviously they will consume more fuel. Keep your engine properlytuned and drive less aggressively. Aggressive driving and frequentapplying of brakes hampers the engine and can lower the mileage ofyour car.
  16. 16. Buy energy saving geysers and dishwasher for your home. Avoidwashing clothes in hot water. Just wash them in cold or warm water.Avoid taking frequent showers and use less hot water. It will help insaving energy require to produce that energy.
  17. 17. Just don’t buy products with lot of packaging. When you buy suchproducts you will end up in throwing the waste material in the garbage,which then will help in filling landfill sites and pollute the environment.Also, discourage others from buying such products.
  18. 18. Planting trees can help much in reducing global warming then anyother method. They not only give oxygen but also take in carbondioxide, during the process of photosynthesis, which is the main sourceof global warming.
  19. 19. Purchase environmentally friendly green power electricity. Greenpower is generated from renewable energy sources such as the sun andwind, producing lower greenhouse .Locate participating green powerutilities in your area by visiting the EPA website.Other options forcreating a greener home include installing solar panels or generatingyour own green power .
  20. 20. There has been an influx of organic food in supermarkets over thepast several years. But of equal importance to consider is where thatfood is coming from. For example, how much of the produce in yoursupermarket is being transported halfway around the world? Check thestickers on those apples and peaches and you’ll see ” Produce of Chile”,“Mexico”, or “China”. Also important to note: how much of that food isactually in season? The transportation of food is a major contributor togreenhouse gases.Easy ways for you to get low carbon food are:•Buying things that are actually in season.•Buying locally-grown fruits and vegetables at farmers markets.•Joining a CSA.
  21. 21. Always try your best to educate people about global warming andit’s causes and after affects. Tell them how they can contribute their partby saving energy that will be good for the environment. Gatheropportunities and establish programs that will help you to shareinformation with friends, relatives and neighbors.
