Global Warming

Theories about global warming first originated during the late 19th century, by Swedish scientists while observing the change in temperature of polluted air. They concluded that the earth is warming up because human has been releasing pollutants into the air. These theories lead to numerous debates among scientists. They believed that since 1896, carbon dioxide released into the air as the byproduct of burning coal for energy is the main culprit of the greenhouse effect. By estimation, carbon dioxide in the air has increased 30 percent since 1750.

Not until 1949, after investigating the phenomenon of rising air temperature in Europe and North America from 1850 to 1940 compared to other location on earth, English scientists reached the conclusion that the industrial revolution at industrialized nations increased the polluting carbon dioxide, thus causing these two regions warmer than the undeveloped nations.

In 1958, studies at the Mauna Loa Observatory in Hawaii, which is located at altitude 3,345m, proved that carbon dioxide is the primary cause of the global warming. In 1976, methane, chlorofluorocarbon CFC, nitrogen oxide NOx are also confirmed to be the cause of the greenhouse effect.

In 1990, 49 scholars who earned the Nobel Prize called upon all nations on earth to immediately take measures to restraint air pollution in order to save the earth.

The most recent studies of the two scientists Karl and Trenberth printed in the Sciences magazine, December 2003 issue, revealed the urgency of global warming. According to their estimation, from 1990 to 2100, the temperature on the ground will increase from 3.1 to 8.9 degree Fahrenheit (1.6 to 4.2 degree Celsius.) The rising temperature will melt the icy Greenland and Antarctica, and could flood the continents. It will shrink the habitable land on earth. The consequences:

• The earth will suffer unusual heat waves
• Drought will occur more often, and more widespread
• Storm, and hurricane could become less predictable
• Environment will be altered
• The sea level will be rising about 75cm in 2100

The advantages of solar energy are:

• No air pollution
• Don’t cause the greenhouse effect
• Don’t produce solid waste, and air pollutants like coal, natural gas, oil, and nuclear energy

Solar energy is the best source of energy for Viet Nam, regarding the geographical condition and the demand of economic development. Solar energy will be the exciting source that contributes to:

• Limiting the greenhouse effect, and the global warming
• Solving the environment pollution caused by population growth
• Supplementing the deficiency of energy in the future when the world’s coal, oil and gas reserves depleted
