Global Warming

By: Austin

what is global warming
What is Global Warming
  • 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
Greenhouse Effect
  • 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
Effects to business world
  • 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
Impacts to Antarctica
  • 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 Antarctica—the Antarctic Peninsula—have been collapsing in recent years, consistent with the rapid warming trend there since 1945.
effects to the world
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
Effects to our lives
  • 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
What U.S. is doing about Global Warming
  • 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
Climate increase
  • 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 7-8°C by 2080 compared to the previously expected 4°C increase.
long term effects
Long Term Effects
  • 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
Effects to Animals
  • 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.
