Global warming is rising at the average temperature of the earth’s surface. Since the late 1800s, the global average temperature has increased by about 0.4 to 0.8 degrees Celsius. According to calculations made by many experts, the average temperature will increase by 1.4 to 5.8 degrees Celsius by 2100. This rate of increase may be much higher than past increases.
Scientists are concerned that the human community and the natural ecosystem can not adapt quickly to climate change. An ecosystem consists of a special territory, living organisms and physical surroundings. Global warming can cause a lot of damage, so they have drafted the Kyoto Protocol treaty to help limit the rest of the world.
Causes of global warming
Global Climatologists (scientists working on climate science) have analyzed global warming since the late 1800s. The majority of climatologists have decided that human activity is responsible for a very large amount of warming. Mankind’s activities contribute to the global warming by increasing Earth’s natural greenhouse effect.
The greenhouse effect heats the surface of the Earth with a complex process involving sunlight, gases, and particles in the atmosphere. Greenhouse gases, heat is the name given to the gases in the atmosphere of the world.
(The most harmful greenhouse gas is carbon dioxide.) The Kyoto Agreement foresees reducing emissions of methane and nitric oxide gases, as well as carbon dioxide.
The main human activities that contribute to global warming are the burning of fossil fuels (coal, oil and natural gas) and the destruction of forests. The most fuel consumption: in automobiles, factories, power plants. With the burning of fossil fuels, carbon dioxide gas (chemical formula CO2) is released. CO2 is a greenhouse gas that slows the outflow of heat.
Trees and other plants use air CO2 in photosynthesis to produce nutrients. The destruction of forests contributes to the proliferation of CO2 by reducing the amount of gas that is destroyed by plants or by decomposing the dead plant cover.
In a small amount, scientist argues that greenhouse gases do not make measurable changes in temperature. They say that natural formation can cause global warming. These occurrences include: solar energy increases.
But the vast majority of climatologists believe that the increase in solar energy is contributing to the warming of the sun is very small.
