Every place, country, city, region has its own climate. Climate plays one of the important roles in people’s life. Climate is defined as the average weather, which means variety of weather conditions as rain, snow, hail, sun, and wind over period of time about 30 years that can be measured in any particular place.( IPCC Third Assessment Report - Climate Change 2001; editor:A.P.Baede) Climate change is a variation of average weather. There are 2 causes of climate change. The first is human activity which includes deforestation, burning fossil fuels, agriculture, transportation and infrastructure. The second is natural causes which include volcanic eruptions and variations in solar outputs. These causes have negative effect on the natural environment which leads to increasing of temperature, increasing in sea level, changing of precipitations, extremely weather, killing species of animals, birds, fish and plants. This essay will show that the causes of climate change have different effects on the environment. Atmospheric carbon dioxide variations, volcanic eruptions and solar outputs, have negative impacts on animals, plants, and environment.
Climate is always changeable. One winter can be early, another late; one summer wet, another dry (Carter 2000,34). For the last century climate has dramatically changed. Consequences of climate change may manifest itself as rapid and through the long period of time. Climate change could lead to number of catastrophic disasters as droughts, earthquakes, floods, hurricanes, tornadoes and volcanic eruptions. For example earthquakes in New Zealand, China, Chilie, and Haiti, floods in Australia, Pakistan and India, volcanic eruption in Iceland, tornado in Dakota in the USA, Montana supercell thunderstorm and recent disasters in Japan. By climatologists’ evidence there are two causes with several factors that have a response for the Earth’s climate. They are: human activity which includes
