What is Global Warming

• http//www.nrdc.org/globalWarming/f101.asp1
• Carbon dioxide and other air pollution that is
  collecting in the atmosphere like a thickening
  blanket, trapping the sun's heat and causing the
  planet to warm up. Coal-burning power plants are
  the largest U.S. source of carbon dioxide
  pollution -- they produce 2.5 billion tons every
  year. Automobiles, the second largest source,
  create nearly 1.5 billion tons of CO2 annually.

Greenhouse Effect

  tml
• Global warming is also known as the "Greenhouse
  effect". The "Greenhouse Earth" is surrounded by
  a shield of atmospheric gases, rather than a
  glass or a plastic cover. The air that makes up
  our atmosphere consists primarily of nitrogen and
  oxygen molecules. A large number of "trace gases"
  make up the remainder of air's composition.

Effects to business world

• http//www.global-warming-debate.com/
• Global warming is a reality that is already
  putting the financial pinch on weather-dependent
  businesses. In New England, maple syrup producers
  are reeling from another dismal sap season. The
  region's ski resorts are losing tens of millions
  of dollars every winter there is reduced snowfall.

Impacts to Antarctica

• http//www.climatehotmap.org/antarctica.html
• The impacts of warming temperatures in Antarctica
  are likely to occur first in the northern
  sections of the continent, where summer
  temperatures approach the melting point of water,
  32?F (0?C). Some ice shelves in the northernmost
  part of Antarcticathe Antarctic Peninsulahave
  been collapsing in recent years, consistent with
  the rapid warming trend there since 1945.

Effects to the World

• (04/26/2002) Scientists say global temperatures
  during first 3 months of 2002 were higher than at
  any time in the past 1,000 years, warm major
  winter floods and summer temperatures of 40C
  (104F) are likely to become common in Britain due
  to global warming.

Effects to our lives

• http//www.ucsusa.org/global_environment/global_wa
  rming/index.cfm
• As the Earth continues to warm, there is a
  growing risk that the climate will change in ways
  that will seriously disrupt our lives. While on
  average the globe will get warmer and receive
  more precipitation, individual regions will
  experience different climatic changes and
  environmental impacts.

What U.S. is doing about Global Warming

• http//healthandenergy.com/global_warming.htm
• While the U.S. is responsible for one-quarter of
  all the pollution that causes global warming,
  politicians in Washington have taken no steps to
  reduce global warming emissions, and the U.S.
  refused to join the 128 countries that have
  ratified the Kyoto Protocol.This international
  global warming pollution reduction treaty seeks
  to reduce emissions about five percent below 1990
  levels by 2008-2012 by setting up an emissions
  trading system and will officially go into effect
  February 16, 2005.

Climate increase

• http//www.eces.org/archive/ec/globalwarming/impac
  tsgeneral.shtml
• Head of leading climate research institute warns
  new research shows global warming could increase
  temperatures double previous predictions UK
  temperatures, for example, could rise by 7-8C by
  2080 compared to the previously expected 4C
  increase.

Long Term Effects

• http//eces.org/archive/ec/globalwarming/wildlife.
  shtml
• According to the study, the eastern Midwest and
  Great Lakes region could be the hardest hit by
  the long-term effects of global warming, with up
  to a 30 percent net loss in the number of
  neotropical migrant species summering in the
  region.

Effects to Animals

• http//library.thinkquest.org/CR0215471/global_war
  ming.htm
• Although the greenhouse effect makes the earth
  able to have people living on it, if there gets
  to be too many gases, the earth can get unusually
  warmer, and many plants, animals, and people will
  die.
