How Do Humans Contribute to Global Warming?

Throughout most of human history, and certainly before human beings emerged as a dominant species throughout the world, all climate changes were the direct result of natural forces.Industrial Age Accelerates Global WarmingThat changed with the start of the Industrial Revolution, when new agricultural and industrial practices began to alter the global climate and environment. Before that time, human activity didn’t release many greenhouse gas, but population growth, deforestation, factory farming, and the widespread use of fossil fuels are creating an excess of greenhouse gases in the amosphere and contributing to globe warming.

Top Causes Of Globe Warming

1Carbon Dioxide From power Plants

many people have created solutions for the pollution caused by power plants. For example, products that help to reduce the green house emissions have emerged. Filters that improve the quality of the air released into the atmosphere have been created to solve this problem. In addition, government regulations have been placed to force owners of large industrial buildings to improve the quality of the air produced by their buildings. Finally, hydrogen power has also become a way of reducing carbon. According to Tom Simonite of http://www.newscientisttech.com/ using carbon is better than using water to generate power, and it is completely environmentally friendly.

2.Pollution Emitted from Cars

Driving to work in the morning is one example of this. When your stuck in traffic, how long does your car stay idle on the road, releasing it’s pollution into the air? There are approximately, 3 billion vehicles being used today. Similarly with the power plants, cars also emit carbon into the air. Cars emit millions of tons of pollutants into the air. In some dense cities, this causes some of the smog and ozone problems. 1,500 cases of cancer are reported each year from pollution.

3.Deforestation

In the past, many countries demolished forests to fuel a growing market for wooden goods; chairs, tables, homes, and so forth, so their country can grow and prosper. Now, when developing nations are trying to build their nations, they can’t because trees are made up of 50% carbon. Many countries need to destroy their forests to make room for farm land and feed their people. Other countries need to create products and help their countries economies.

What Causes Global Warming

Scientists have determined that a number of human ativities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.
Greenhouse Gases and Global WarmingWhile many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gasese.
By driving cars, using electricity from coal-fired power plants, or heating our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the atmosphere. Deforestation is another significant source of greenhouse gases, because fewer trees means less carbon dioxide conversion to oxygen.
During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by 31 percent. Over the same period, the level of atmospheric methane has risen by 151 percent, mostly from agricultural activities such as raising cattle and growing rice.

Effect Of The Globe Warming

Less Ice in the Arctic
Greenland’s MeltingGreenland is melting at a rate of 52 cubic miles per year—much faster than once predicted. If Greenland’s entire 2.5 million cubic kilometers of ice were to melt, it would lead to a global sea level rise of 7.2 meters, or more than 23 feet.

The Northwest Passage Becomes a Reality
"Less Ice in the ArcticThe amount of ice in the Arctic at the end of the 2005 summer “was the smallest seen in 27 years of satellite imaging, and probably the smallest in 100 years.” Experts said it’s the strongest evidence of global warming in the Arctic thus far."

More FloodsDuring the summer of 2007, Brit

ain suffered its worst flood in 60 years. Scientists point the finger directly at global warming, which changed precipitation patterns and is now causing more “intense rainstorms across parts of the northern hemisphere.”

More FiresHotter temperatures could also mean larger and more devastating wildfires.

Higher Sea Levels;Scientists believe sea levels will be three feet higher by the end of the century than they are now.
