Science researchers have defined global warming the increase in average temperature of the world's atmosphere. Over the last few decades, global warming has imposed a serious threat to the world. It has increased the world's average temperature in many different ways, including the arctic shrinkage, frozen methane release, and seas level rise. The predicated, average temperature has increase extreme weather events, and changes in rainfall patterns, causing floods, heat waves, storms, and cyclones. Studies have found that the temperatures keep increasing in the amount that they are now in; by 2100 the Earth's temperature will increase by at least eleven degrees Fahrenheit or more.
The temperature of the air near the world's surface gets hotter through the process called greenhouse effect. The greenhouse effect is a common occurrence that happens when shortwave light come, from the sun to the world and through a thick layer of greenhouse gases. Some greenhouse gases are producing naturally while others are the direct result of human activities. The greenhouse gases are methane, carbon dioxide, nitrous oxide, ozone, and water vapor; that occur naturally. The cause greenhouse effect by capturing and absorbing solar energy; for without the greenhouse effect, the plant would be indifferent to life because of the temperature earth surface. There are a few human activities that increase the levels of these natural gases. Many scientists believe that growth in temperature is causes by human activities, one of the main causes of global warming. The emission of certain greenhouse gases into the atmosphere where the human activities increase. The burning of fossil fuels such as oil, natural gas, and coal has increases the greenhouse effect. Carbon dioxide is the main gas that humans have affected such as wood products, solid waste, and burnt the emit. It increased by nearly 30% since 1700 because of human...
