Title: GLOBAL WARMING


1
  • GLOBAL WARMING

2
Global Warming Alarm

Global warming
  • What is Global Warming? Warming is defined as the
    increase of the average
  • temperature on Earth. As the Earth is getting
    hotter, disasters like hurricanes, droughts and
    floods are very frequent.

4
Causes Of Global Warming
  • Green house effect
  • Carbon Dioxide from Power Plants
  • Carbon Dioxide Emitted from Cars 
  • Carbon Dioxide from Airplanes
  • Carbon Dioxide from Buildings
  • Methane 

5
.Continued
  • Water Vapor in the Atmosphere Increasing
  • Nitrous oxide
  • Carbon in Atmosphere and Ocean
  • Tundra

6
Effects of Global warming
  • Plant and animal range shifts and population
    changes
  • Coral reef bleaching
  • Downpours, heavy snowfalls, and flooding
  • Droughts and fires

7
.Continued
  • Heat waves and periods of unusually warm weather
  • Ocean warming
  • sea-level rise and coastal flooding
  • Glaciers melting
  • Arctic and Antarctic warming Spreading diseases
  • Earlier spring arrival

Institutions To Monitor Global Warming
  • Lamont-Doherty earth observatory (LDEO)
  • Nasa Godart institute for space studies (GISS)
  • International research institute for climate and
    society
  • Cooperative institute for climate applications
    and research (CICAR)
  • Center for environmental research and
    conservation (CERC)
  • Center for climate systems research (CCSR)
  • Center for research on environmental Decisions
    (CRED)
  • Global roundtable on climate change (GROCC)
  • Lenfest center for sustainable energy (LCSE)
  • Center for hazards and risk research (CHRR)
  • The educational programs of the environmental law
    clinic

10
Global Average Temperature
11
Evidence of Global warming
  • Carbon dioxide increasing in atmosphere
  • Methane also increasing
  • Disappearing glaciers
  • Melting Antarctic sea ice
  • Ocean warming with coral bleaching

14
Polar Bear Panic
  • Polar bears starting to turn up drowned and
    at some point will become extinct due to global
    warming.

15
An Inconvenient Truth
  • Intellectually Exhilarating! An Inconvenient
    Truth is a necessary film
  • A.O. Scott, New York Times
  • It is difficult to get a man to understand
    something when his salary depends on his not
    understanding it Upton Sinclair

16
Skeptics View
  • Natural phenomenon
  • Not man made

17
Jupiter
  • Some parts of Jupiter are now as much as
    six degrees Celsius warmer than just a few years
    ago. Imke de Pater and Philip Marcus of
    University of California, Berkeley

18
Mars
  • Carbon dioxide "ice caps" near Mars's south pole
    had been diminishing for three summers in a row.
    2005 data from NASA's Mars Global Surveyor and
    Odyssey missions
  • A simultaneous rising in temperature on both
    Mars and Earth suggest that climate change is
    indeed a natural phenomenon as opposed to being
    man-made. Habibullo Abdussamatov, head of space
    research at St. Petersburg's Pulkovo Astronomical
    Observatory in Russia

19
Saturn
  • Storms on Saturn indicate a climate change
    occurring on that planet. NASA

20
Alarmists Say
  • Global warming may raise the oceans 23 feet,
    submerging cities from Sidney to New
    York. Jonathan Gregory, climate scientist at the
    University of Reading in England

21
Climate Education Worldwide
  • Climate change is a global issue, but its impacts
    and how it is perceived differ greatly around the
    world. German student Simone Lepper shares her
    experiences teaching climate change in Germany,
    Estonia, and Cameroon.

Current News on Global warming
  • January 15, 2008...The year 2007 tied 1998 as the
    second warmest year on record 2005 being the
    warmest year. An analysis by NASA's Goddard
    Institute for Space Studies (GISS).
  • June 21, 2007...China is now producing the most
    CO2 of any country in the world, surpassing the
    United States. However, per capita the U.S is
    emitting over 4 times as much as China, 21 tons
    per American vs 5 tons per Chinese.

25
Frequently Asked Questions
  • How long does carbon dioxide remain in the
    atmosphere? 
  • Do extreme events such as heat waves and floods
    have
  • What is the cause of sea level rise?
  • How long does the carbon dioxide remain in the
    atmosphere?
  • How much in carbon emissions does the U.S.
    produce?

26
The Final Quote
  • Preserving the environment
  • Conserving energy
  • Providing for clean air and water
  • Developing alternative forms of power
  • Reducing our dependence on oil
  • Each stands on its own benefits. Let us join
    together to make them happen.
