Global Warming Global Warming Presentation Transcript

  • Globalization and Global Warming UNYP 2007 TEAM: Lior, Eliska, Martin
  • content
    • introduction
    • about global warming (GW)
    • factors leading to GW
    • average temperatures
    • global impact of GW
    • available solutions
    • summary
  • Why this TOPIC?
    • up-to-date problem
    • everybody has an opinion
    • connected with globalization
  • Globalization and Global Warming
    • The cause of global warming is human activity.
    • Examples:
    • Fossil fuel combustion associated with industrial development.
    • The burning of forests.
    • Biomass combustion - the burning of wood, coal, and dung for cooking and heat.
  • Globalization and Global Warming
    • The inability to solve global warming, is emblematic of the failures of globalization.
    • However, it is also an opportunity to use the forces of globalization for the good of the planet's health.
  • Global Warming
    • The most important factors in halting climate change is reducing levels of carbon dioxide in the atmosphere.
    • The global average temperature has risen by 0.6 ºC in the last 100 years.
    • The cost of dealing with the effects of climate change is almost $300 billion every year.
  • Projected Changes In Global Temperature
  • Past EARTH temperatures Graph based on data from the Climatic Research Unit of the University of East Anglia.
  • Past EARTH temperatures Graph based on data reported by Moberg,, in Nature, V. 433, 10 February 2005.
  • Past EARTH temperatures Global temperature variation for the past 425,000 years. The present is at the right. The horizontal 0 line represents the 1961– 1 990 average global temperature. The numbers on the left show the variation from that baseline in °C. Image based on data from the National Oceanographic and Atmospheric Administration.
  • The Greenhouse Effect
    • The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere trap energy from the sun.
    • Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder.
    • Because of how they warm our world, these gases are referred to as greenhouse gases.
  • The Greenhouse Effect
  • Who Is Responsible?
    • The countries that emit most carbon dioxide contribute most to climate change.
    • The world's biggest polluter is the United States . It produces 20.4 tons of carbon dioxide per person, annually.
    • The UK release 9.5 tons per person, annually.
    • In China , carbon dioxide emissions are only 1.9 tons per person, annually.
  • What Can Be Done?
    • In May 1997 Consumer Alert formed a subgroup of the National Consumer Coalition on climate change policy, the "Cooler Heads" Coalition, to address the consumer impact of climate change policies.
    • A total of 178 countries (including 39 industrialized nations) signed up to the Kyoto Protocol in 2001.
    • United States, the world's largest emitter, has not come on board.
    • Reducing reliance on fuel will help to slow down the effects and will help to adapt better to changes in the future.
  • Possible Implications Of Environmental Policies
    • 1. According to a report by the Department of Energy, stringent targets to reduce fossil-fuel emissions in the US will cause energy-intensive industries , including steel, iron, chemical, rubber and plastic, to flee from the developed countries to undeveloped countries, taking with them hundreds of thousands of jobs.
  • Possible Implications Of Environmental Policies
    • 2. Carbon taxes will cause relatively large income losses in the poorest one-fifth of the population. The poor, because they spend a greater proportion of their income on necessities, would have few ways to cut back to compensate for higher living costs.
  • Possible Implications Of Environmental Policies
    • 3. Stabilizing emissions at 1990 levels by 2010 would reduce the growth of US per capita income by 5% per year.
    • 4. Senior citizens on fixed incomes would find their energy costs escalating and their income dwindling.
  • Will The Policies Actually Stop Global Warming?
    • By all estimates, only severe reductions in global CO2 emissions -- on the order of 60 percent or more -- will alter the forecasts.
    • The resulting economic dislocations would be tremendous, potentially outweighing the negative impacts of even the most apocalyptic warming scenario.
    • If the policies do not include developing nations the result will likely be a reallocation of emissions to developing nations, not a reduction of emissions.
  • Summary - list
    • Has the climate changed during the 20th century?
    • What causes this climate change?
    • What climate changes are expected for the future?
    • What are the likely consequences of climate change?
    • How could Climate Change affect us in the future?
    • How could greenhouse gas emissions be reduced?
    • Are recent extreme weather events due to global warming?
    • Do man-made greenhouse gases matter compared to water vapor?
    • Can ecosystems adapt to Climate Change?
    • What is and is not known with certainty about Climate Change?
    • Conclusion
    • Other views
  • Summary
    • global problem
    • atributable to human activities
    • nature can change it by itself
    • demand-suply law may change it
