GLOBAL WARMING

Our planet warms due to Greenhouse gases. It exists naturally in our atmosphere. It trapped heat energy which comes from the sun. This process is called the greenhouse effect. If it is not present, the surface of the earth will be cold as surface of moon about –18 Celsius. Average temperature of the earth 's surface is about 15 Celsius. Measurement taken from all over the world has shown that global climate is changing. A half of the degree Celsius is increased from last 100 years. Humans have been releasing extra greenhouse gases during this time. In these gases includes carbon-dioxide, methane and nitrous oxide. It is assumed that emissions of greenhouse are by man-made from the increased use of fossil fuels. These fossil fuels are responsible for global warming during the 20th century. These gases are released by the exhausts of motor vehicles and by the cutting down of forest. If all these activities will continue, the temperature of the earth’s surface may 3 degree warmer by the end of the 21th century. This rapid change in temperature has many impacts on the environment …show more content…

Different countries scientist makes a strong argument against global warming. The Scientist has a strict opinion of global warming as a rise in atmospheric temperature they do not consider the atmospheric precursor as valid evidence. The Scientist has evidence that global warming is not real. Global warming is in two steps. Increase in fossil fuel cause increase in carbon dioxide in the air can cause climate change. Fossil fuels include oil, natural gas and coal. In the first part of hypothesis increasing in fossil fuel can increase carbon dioxide in the air. In second part of hypothesis increase in carbon dioxide in the air cause climate change. The second part of hypothesis have never proven. In first part increases in fossil fuels can cause increased carbon dioxide in the air. It is proved by NASA that is not
