8.Global Warming Effect: Rise in sea levels worldwide

Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the U.S. However, many nations around the world will experience the effects of rising sea levels, which could displace millions of people. One nation, the Maldives, is already looking for a new home, thanks to rising sea levels.

7.Global Warming Cause: Increase in usage of chemical fertilizers on croplands

In the last half of the 20th century, the use of chemical fertilizers (as opposed to the historical use of animal manure) has risen dramatically. The high rate of application of nitrogen-rich fertilizers has effects on the heat storage of cropland (nitrogen oxides have 300 times more heat-trapping capacity per unit of volume than carbon dioxide) and the run-off of excess fertilizers creates ‘dead-zones’ in our oceans. In addition to these effects, high nitrate levels in groundwater due to over-fertilization are cause for concern for human health.

6.Fossil Fuel Recovery Processes, Including Mining

recovering fossil fuels has a big impact on the causes and effects of global warming. Mining into the earth releases stored up carbon, which then goes into the air and atmosphere. This contributes to global warming.

5.RainForest Deforestation

One of the causes and effects of global warming is the rain forest deforestation that is occurring on a widespread basis. The forests of the world act as carbon sinks, sequestering carbon in the earth and trees where it is harmless. When the trees are cut down this carbon is released. In addition, the trees take in carbon from the air and turn it into oxygen

4.Methane Greenhouse Gas From Farm Animals

One of the natural causes of global warming is the release of methane gas from livestock and agricultural animals. This causes an increase in methane in the atmosphere, which helps trap heat near the earth and raises the temperature. Even though this is one of the natural causes of global warming, an increase in the number of farm animals raised has greatly increased methane greenhouse gas emissions as well.

3. Pollution from Trucks

Trucks, although less in volume, make up for a large portion of the earth's pollution with each truck's individual output of pollutants. The difference between cars and trucks is the type of fuel used to run them. Diesel, the standard for trucks and other vehicles used for carrying large loads, is known to be less clean than gasoline. Trucks roaring down streets can bee seen from a mile away with a tiny smoke stack blowing out the product of having to carry large amounts of goods from one place to the other.
How can our society get rid of trucks? They are vital for the economic health of certain companies. They are used to build homes and carry supplies, People go camping and carry gear with them, and the list goes on. According to http://www.ucsusa.org, diesel is reaching a point where it can no longer meet the standards of government regulations. What kind of alternative can be used instead?

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 according to http://www.nsc.org.
