SETIAKU (D4 IT A)

Global warming is a process of increasing the average temperature of the atmosphere, oceans, and Earth's land. This happend caused by increased concentrations of greenhouse gases due to human activity through the greenhouse effect such as deforestation and burning fossil. This discovery is recognized by the national science academi of all the major industrial countries
Increasing global temperature is expected to lead to other changes such as rising sea levels, increased intensity of extreme weather phenomena, as well as changes in the number and pattern of precipitation. Consequences of global warming is problem about other crops, the loss of glaciers, and the extinction of various animal species who life in the world.

Global warming happened because:
• The greenhouse effect is the process by which absorption and emission of infrared radiation by atmospheric gases warm the atmosphere of a planet and the lower surface. The greenhouse effect is caused by rising concentrations of carbon dioxide gas (CO2) and other gases in the atmosphere. The increase in CO2 concentration is due to the increase in fuel burning oil, coal and other organic fuels which exceed the ability of plants and the ocean to absorb it for their life.
• Variations of solar radiation can make change the solar energy to reaching the Earth has become a cause of past climate change.

The effects of global warming
• Increased sea surface
• The climate began to unstable or not consistant
• Ekstrem of Global temperature system
• There was a variety of natural disasters in the world
