Global warming presentation

  1. 1. Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.
  2. 2. Methane Release Carbon Dioxide Nitrous Oxide CFCs
  3. 3. Methane Release • Methane is a greenhouse gas that occurs naturally when organic matter is broken down by bacteria when very little oxygen is present • Methane is released in landfills and in rice paddies when the organic matter is trapped underwater. Carbon Dioxide • Factories and vehicles produce large amounts of harmful carbon dioxide by burning fossil fuels that create carbon dioxide emissions. • When carbon dioxide gas traps heat, which causes the earth's temperature to rise.
  4. 4. Nitrous Oxide • Nitrous oxide is released naturally into the atmosphere when wood, leaves and other organic materials are burned. • It is also present in fertilizers designed to accelerate the growth of plants, but they contribute to global warming. CFCs • CFCs or "chlorofluorocarbons" are chemicals that trap heat in the atmosphere, making them a major threat to the environment and a contributor to global warming. • They also deplete the ozone layer because the atoms they release destroy ozone molecules and increase ultraviolet radiation.
  5. 5. Rising Seas Changes in rainfall patterns Increased likelihood • Inundation of fresh water marshlands, low- lying cities. • Droughts and fires in some areas, flooding in other areas. • Such as flooding, hurricane s, etc.
  6. 6. Melting glaciers Widespread Spread of disease • Significant melting of old glaciers is. • Following widespread habitat loss. • Migration of diseases such as malaria to new, now warmer, regions.
  7. 7. Reduce, R euse, Rec ycle. • Choosing reusable products instead of disposables. • Buying products with minimal packaging. • Recycle paper, plastic, newspaper, glass and aluminum cans. Use Less Heat • Adding insulation to walls and attic, and installing weather stripping or caulking around doors and windows. Change Light Bulb • Replace regular light bulbs with compact fluorescent light (CFL) bulbs. Drive Less • Use community mass transit system, and check out options for carpooling to work or school.
  8. 8. Buy Efficient Product • Choose energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs. Use Less Heat Water • Set water heater at 120 degrees to save energy, and wrap it in an insulating blanket. • Buy low-flow showerheads to save hot water. Use The “Of” Switch • Turning off lights when leave a room, and using only as much light as needed. • To turn off television, stereo and computer when not using it. Plant A Tree • Plan a tree at yard or home.
  9. 9. Nearly everyone in the world will need to adjust. Citizens will need reliable information, the flexibility to change their personal lives, and efficient and appropriate help from all levels of government. So it is an important job, in some ways our top priority, to improve the communication of knowledge, and to strengthen democratic control in govermance everywhere. The spirit of fact-gathering, rational discussion, toleration of dissent, and negotiation of an evolving consensus, which has characterized the climate science community, can serve well as a model.
