Title: Global Warming

Global Warming
  • By Austin

What is Global Warming
  • http//
  • 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
  • http//
  • 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//
  • 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//
  • 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
  • http//
  • (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//
  • 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//
  • 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//
  • 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

The Top 10 c02 Producers
Long Term Effects
  • http//
  • 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

Effects to Animals
  • http//
  • 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
