Global warming

what is Global Warming ?!

Global warming is “the increase in the average temperature of the Earth's near-surface air and oceans in recent”.

This temperature increase is caused by a natural process called the greenhouse effect. A blanket of thermal, or greenhouse, gases composed largely of carbon dioxide, methane, nitrous oxide, and other gases are blocking the sun light or Infrared radiation reflects off earth’s surface toward space and cause it to reflect downward, which helps to rapidly increase in earths temperature and cause some Climatic changes.

Scientist believes that within the last 50 years , earths temperature has increased by 38 F and The atmospheric concentrations of CO2 and CH4 have increased by 31% and 149% respectively above pre-industrial levels since 1750.

Global warming causes

A-Natural causes

such as the release of methane gas from arctic tundra and wetlands considering that Methane is a greenhouse gas, and a greenhouse gas will trap heat in the earth's atmosphere.Another natural cause is that the earth is going through a cycle of climate change. This climate change usually lasts about 40,000 years.

B-Man-Made causes

1-Gas emissions and pollution

Burning fossil fuels is one example that causes global warming . Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2.

2-Over population

More people means more food, and more methods of transportation. This means burning of fossil fuels, and more agriculture. . Because more food is needed we have to raise more animals. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution.
