“The greenhouse effect is the most significant economic, political, environment and human facing the 21st century” (By Timothy Wirth, former US Senator and Undersecretary of State for Global Affairs). It is true that nowadays, due to climate change, our planet is warming at an unprecedented level. Following this, the ecosystem and human life is also affected. That is reason why we had to find the solution to address this problem.

According to the studies of scientists throughout the world, the causes of climate change can be divided into two types: natural causes and human causes. First of all, this phenomenon is influence by natural causes that are outside of the climate system. One of this is solar output. The Sun accommodated the Earth with a large heat, therefore, “even small variations in solar output can have an impact on the climate”. To monitor these changes, researcher has observed sunspots and (more recently) measured satellite. When there is an intensification in sunspots, solar output also intensifies. Scientists at the University of Washington have clarified that at the top of the 11-year solar cycle, increased solar output causes a rapid warming of the air of 0.16 °C.

Moreover, the volcano is one of the main factors that cause climate change. When it erupts, it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. This eruption, with the large volumes of gases and ash, can influence climatic patterns. In April 1991, Pinatoba Mountain in the Philippine islands erupted and emitted thousands of tonnes of gases into the atmosphere. Volcanic eruption of this greatness can bring down temperatures in the lower levels of the environment (called the troposphere), and changing climatic dissemination designs. Secondly, humans being are the major cause of global warming. Scientists believe that burning fossil fuels contribute to climate change because we depend on fossil fuels for our energy needs. “A large amount of climate change happens widely because we are burning fossil fuels and that increases gases such as CO2, methane, and some other gases in the atmosphere” (Donald James “Don” Wuebbles) .

Concurring to the Australian Greenhouse Office, the world depends on fossil powers such as oil, coal, and natural gas for 80% of its vitality needs. Subsequently, that makes it exceptionally difficult to switch from fossil fuels to any other forms of energy since we depend on fossil fuels to a huge degree. The emission of greenhouse gasses has expanded significantly from the industrial revolution, generally from the burning of fossil powers for energy, farming, industrial process, and transportation (Ecological Impacts of Climate Change). According to the “Climate Change” graph done by Robert Simmon, carbon dioxide levels have increased nearly 38 percent from 1750 to 2009 and methane levels have increased 148 percent (Riebeek). Deforestation also is one of the reason cause the climate change.
