Global Warming Causes

Global Warming

Causes

1) Carbon Dioxide from Power Plants.
2) Carbon Dioxide Emitted from Cars.
3) Carbon Dioxide from the planes.
4) Carbon Dioxide from Buildings. - Buildings structure emmits about

12% of carbon dioxide.
5)Methane – If carbon dioxide is the main greenhouse

gas, methane is another important one.This gas is twenty times as

important as CO2 for trapping heat in the atmosphere.
6)Water Vapors in the Climate.-This Water vapor is the

very abundant and very poweful greenhouse gas on the earth.
7)Nitrous oxide –This is another greenhouse gas, this

gas is colourless, non-flammable,sweetish odour, and due to its

characteristic it is called "laughing gas".
8)Deforestation – It is another major reason of

atmospheric carbon dioxide. Deforestation results to 20-25% of carbon

generation which mix with atmosphere.
9)More people – the increasing number of people on

earth is one of the greatest factors in global warming. The world’s

population has grew four times larger in last 100 years. More peoples

means more fossile fuels are burned. This has led to a massive rise in

the levels of greenhouse gases in earth’s atmosphere.
10)City life – life in large cities is comfortable and

convenient, but the energy ths lifestyle requires has a high

environmental cost.A) Home and businesses – heating,

lighting and air-conditioning in homes and business create a lot of

greenhouse gases. Together, buildings account for almost 30 percent of

all CO2 released by cities, with around 70 percent of this coming from

our houses and apartments.B)Industry – People living

in cities use huge amount of power,food,water and manufactured

products. All of this has to come from somewhere. Power

stations,factories and processing plants create almost half of all our

greenhouse gases.C)Transportation – People in cities

requires cars and buses to get around, and business needs trucks to

shift goods. These fuel-hungry vehicles create more than 70 percent of

CO2 transportation emissions. The rest is from trains and

airplanes.D)Building problems – Growing city

populations nedd plsces to live, work and shop. Constuction work and

making concrete release tons of CO2 even before the buildings are

complete.Pollution problem - Burning fossile fuels, the major cause of

global warming, also causes air pollution. Exhaust gases from

factories,cars and other vehicles contains greenhouse gases that trap

heat in our atmosphere. As well as making Earth warmer, some of these

gases can create smog amd acid rain.

How smog is created? – Smog is formed when exhaust

gases from cars and factories react with oxygen in the air, warmed by

high temperatures and uv rays from the sun. This creates a thick cloud

of nitrogen dioxide, ozone, and other harmful gases, which can irritate

or even permanently damage the lungs.

Heat island effect– Concrete buildings and sidewalks

trap heat during the day, leaving and towns several degrees warmer than

surrounding country areas in the evenings. This is called the heat

island effect. The increased heat in cities and towns also leads to

higher levels of air pollution.

Global Warming Solutions- Using energy which we have

available efficiently and moving to renewable energy like wind, solar,

geothermal, and bioenergy would definitely reduce our emissions of

heat-trapping gases.By putting energy efficiency, renewable energy, and

vehicle technology solutions.
