Global warming By Siddharth Koyal

  1. 1. Global Warming By Siddharth Koyal
  2. 2. What is Global Warming??• Global warming is the rise in the average temperature of Earths atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earths mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.

  4. 4. What is the cause of Global Warming• Scientists have spent decades figuring out what is causing global warming. Theyve looked at the natural cycles and events that are known to influence climate. But the amount and pattern of warming thats been measured cant be explained by these factors alone. The only way to explain the pattern is to include the effect of greenhouse gases (GHGs) emitted by humans.
  5. 5. List of Greenhouse Gasses• Carbon dioxide• Carbon Monoxide• Methane• Nitrous oxide• Tetrafluoromethane• Hexafluoroethane• Sulfur hexafluoride
  6. 6. The Greenhouse effect…..
  7. 7. The 2 different Types of Greenhouse Effects• There are two common meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earths climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earths natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels (mainly petroleum, coal, and natural gas).
  8. 8. Who tells us about all the causes?• To bring all this information together, the United Nations formed a group of scientists called the Intergovernmental Panel on Climate Change, or IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming. Each report represents a consensus, or agreement, among hundreds of leading scientists.•
  9. 9. The Impact of Global Warming.• Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.• Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.• Sea level rise became faster over the last century.• Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.• Precipitation (rain and snowfall) has increased across the globe, on average.• Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
  10. 10. IF warming continues…..• Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).• Hurricanes and other storms are likely to become stronger.• Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.• Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.• Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.• Some diseases will spread, such as malaria carried by mosquitoes.
